In Part 36, we discussed, associating event handler methods to events using the attributes of HTML tags. In this video we will discuss using DOM object property to assign event handlers to events. First let us understand, what is DOM DOM stands for Document Object Model. When a browser loads a web page, the browser creates a Document Object Model of that page. The HTML DOM is created as a tree of Objects. Example : [html] [head] [title]My Page Title[/title] [/head] [body] [script type="text/javascript"] [/script] [div] [h1]This is browser DOM[/h1] [/div] [/body] [/html] JavaScript can be used to access and modify these DOM objects and their properties. For example, you can add, modify and remove HTML elements and their attributes. Along the same lines, you can use DOM object properties to assign event handlers to events. We will discuss the DOM object in detail in a later video session. We will continue with the same examples that we worked with in Part 36. Notice that in this case, we are assigning event handlers using the DOM object properties (onmouseover & onmouseout) instead of using the attributes of the HTML tag. We are using this keyword to reference the current HTML element. In this example "this" references the button control. [input type="button" value="Click me" id="btn"/] [script type="text/javascript"] document.getElementById("btn").onmouseover = changeColorOnMouseOver; document.getElementById("btn").onmouseout = changeColorOnMouseOut; function changeColorOnMouseOver() { this.style.background = 'red'; this.style.color = 'yellow'; } function changeColorOnMouseOut() { this.style.background = 'black'; this.style.color = 'white'; } [/script] The following example is same as the above. In this case we are assigning an anonymous function to onmouseover & onmouseout properties. [input type="button" value="Click me" id="btn" /] [script type="text/javascript"] document.getElementById("btn").onmouseover = function () { this.style.background = 'red'; this.style.color = 'yellow'; } document.getElementById("btn").onmouseout = function () { this.style.background = 'black'; this.style.color = 'white'; } [/script] If an event handler is assigned using both, i.e an HTML attribute and DOM object property, the handler that is assigned using the DOM object property overwrites the one assigned using HTML attribute. Here is an example. [input type="button" value="Click me" id="btn" onclick="clickHandler1()"/] [script type="text/javascript"] document.getElementById("btn").onclick = clickHandler2; function clickHandler1() { alert("Handler set using HTML attribute"); } function clickHandler2() { alert("Handler set using DOM object property"); } [/script] Using this approach you can only assign one event handler method to a given event. The handler that is assigned last wins. In the following example, Handler2() is assigned after Handler1. So Handler2() owerites Handler1(). [input type="button" value="Click me" id="btn"/] [script type="text/javascript"] document.getElementById("btn").onclick = clickHandler1; document.getElementById("btn").onclick = clickHandler2; function clickHandler1() { alert("Handler 1"); } function clickHandler2() { alert("Handler 2"); } [/script]

Binds the click event handler to the button using on function 2. We are passing 3 arguments to the on() function a) The name of the event b) JSON object that contains data that we want to pass to the event handler c) Event handler method name 3. In the event handler method (sayHello), we access the data using event object's data property. Replace < with LESSTHAN symbol and > with GREATERTHAN symbol <html> <head> <title></title> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { $('#btnClickMe').on('click', { firstName: 'John', lastName: 'Doe' }, sayHello); $('#btnClickMe').on('click', { firstName: 'Mary' }, sayHello); $('#btnClickMe').on('click', sayHello); function sayHello(event) { if (event.data == null) { alert('No name provided'); } else { alert('Hello ' + event.data.firstName + (event.data.lastName != null ? ' ' + event.data.lastName : '')); } } }); </script> </head> <body style="font-family:Arial"> <input id="btnClickMe" type="button" value="Click Me" /> </body> </html> Output : Hello John Doe Hello Mary No name provided

Events in JavaScript

Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/01/events-in-javascript.html What is an event An event is a signal from the browser that something has happened. For example, 1. When a user clicks on an HTML element, click event occurs 2. When a user moves the mouse over an HTML element, mouseover event occurs When events occur, we can execute JavaScript code or functions in response to those events. To do this we need to associate JavaScript code or functions to the events. The function that executes in response to an event is called event handler. In JavaScript, there are several ways to associate an event handler to the event 1. Using the attributes of an HTML tag 2. Using DOM object property 3. Using special methods In this video we will discuss associating event handler methods to events using the attributes of HTML tags. In the following example, the code to execute in response to onmouseover & onmouseout events is set directly in the HTML markup. The keyword "this" references the current element. In this example "this" references the button control. [input type="button" value="Click me" id="btn" onmouseover="this.style.background= 'red'; this.style.color = 'yellow'" onmouseout="this.style.background= 'black'; this.style.color = 'white'" /] The above example, can be rewritten as shown below. In this case the code to execute in response to the event is placed inside a function and then the function is associated with the event. [input type="button" value="Click me" id="btn" onmouseover="changeColorOnMouseOver()" onmouseout="changeColorOnMouseOut()" /] [script type="text/javascript"] function changeColorOnMouseOver() { var control = document.getElementById("btn"); control.style.background = 'red'; control.style.color = 'yellow'; } function changeColorOnMouseOut() { var control = document.getElementById("btn"); control.style.background = 'black'; control.style.color = 'white'; } [/script] Events are very useful in real-world applications. For example they can be used to 1. Display confirmation dialog box on submitting a form 2. Form data validation and many more How to show confirmation dialog in JavaScript [input type="submit" value="Submit" id="btn" onclick="return confirmSubmit()" /] [script type="text/javascript"] function confirmSubmit() { if (confirm("Are you sure you want to submit")) { alert("You selected OK"); return true; } else { return false; confirm("You selected cancel"); } } [/script] JavaScript form validation example : In this example, both First Name and Last Name fields are required fields. When you type the first character in any of the textbox, the background colour is automatically changed to green. If you delete all the characters you typed or if you leave the textbox without entering any characters the background colour changes to red indicating the field is required. We made this possible using onkeyup and onblur events. onkeyup occurs when the user releases a key. onblur occurs when an element loses focus. [table] [tr] [td] First Name [/td] [td] [input type="text" id="txtFirstName" onkeyup="validateRequiredField('txtFirstName')" onblur="validateRequiredField('txtFirstName')"/] [/td] [/tr] [tr] [td] Last Name [/td] [td] [input type="text" id="txtLastName" onkeyup="validateRequiredField('txtLastName')" onblur="validateRequiredField('txtLastName')"/] [/td] [/tr] [/table] [script type="text/javascript"] function validateRequiredField(controlId) { var control = document.getElementById(controlId); control.style.color = 'white'; if (control.value == "") { control.style.background = 'red'; } else { control.style.background = 'green'; } } [/script]

Events are listening out for interactivity by the user. It also could include a change in state; for example you could trigger an event if the HTML5 video player was playing, paused or in the stop position. This allows us to create interactive pages and show, hide or update content to notify the user. This is why it's so important to understand events.

Event bubbling in JavaScript
 
15:01
Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/01/event-bubbling-in-javascript.html What is event bubbling Let us understand this with an example. HTML elements can be nested inside each other. For example a button element can be nested inside a span element and the span element inturn can be nested inside a div element. Notice that we have onclick attribute specified for all the 3 elements. [html] [head] [style type="text/css"] .styleClass { display: table-cell; border: 1px solid black; padding: 20px; text-align: center; } [/style] [/head] [body] [div class="styleClass" onclick="alert('Div click handler')"]DIV element [span class="styleClass" onclick="alert('Span click handler')"]Span element [input type="button" value="Click me" onclick="alert('Button click handler')" /] [/span] [/div] [/body] [/html] A click on the button, causes a click event to be fired on the button. The button click event handler method handles the event. The click event then bubbles up to the button element parent (span element), which is handled by the span element event handler method. The click event then bubbles up to the span element parent (div element). This is called event bubbling. Notice that if you click on the [span] element, it's event handler and it's parent([div]) element event handler are called. If you click on the [div] element, just the [div] element event handler method is called. So, the event bubbling process starts with the element that triggered the event and then bubbles up to the containing elements in the hierarchy. The following example is similar to the one above, except we removed the onclick attribute from button and span elements. Because of event bubbling, when you click on the button or the span element, the event gets handled by the div element handler. [html] [head] [style type="text/css"] .styleClass { display: table-cell; border: 1px solid black; padding: 20px; text-align: center; } [/style] [/head] [body] [div class="styleClass" onclick="alert('Click event handled by DIV element')"]DIV element [span class="styleClass"]Span element [input type="button" value="Click me"/] [/span] [/div] [/body] [/html] When the event gets bubbled, the keyword this references the current element to which the event is bubbled. In the example below, we are using "this" keyword to reference the current div element and change it's border color. When you click on the innermost [div] element, all the 3 [div] elements border get changed due to event bubbling. [html] [head] [style type="text/css"] .divStyle { display: table-cell; border: 5px solid black; padding: 20px; text-align: center; } [/style] [/head] [body] [div id="DIV1" class="divStyle"] DIV 1 [div id="DIV2" class="divStyle"] DIV 2 [div id="DIV3" class="divStyle"] DIV 3 [/div] [/div] [/div] [script type="text/javascript"] var divElements = document.getElementsByTagName('div'); for (var i = 0; i [ divElements.length; i++) { divElements[i].onclick = function () { this.style.borderColor = "red"; alert(this.getAttribute("id") + " backgound changed"); } } [/script] [/body] [/html] Stopping event bubbling : If you don't want the event to be bubbled up, you can stop it. With Internet Explorer 8 and earlier versions event.cancelBubble = true With Internet Explorer 9 (and later versions) & all the other browsers event.stopPropagation()

Binding event handlers using jquery on method
 
08:42
Link for all dot net and sql server video tutorial playlists https://www.youtube.com/user/kudvenkat/playlists?sort=dd&view=1 Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/04/binding-event-handlers-using-jquery-on.html In this video we will discuss binding event handlers to events using on() method in jQuery In Part 33 of jQuery Tutorial, we discussed how to bind event handlers using bind() method. If you are using jQuery 1.7 or higher, you should be using on() and off() methods instead of bind() and unbind() methods. The syntax for using on() and off() methods is very similar to using bind() and unbind() methods. The following example is the same example we worked with in Part 33. Instead of using bind() and unbind() we are using on() and off() methods. Replace < with LESSTHAN symbol and > with GREATERTHAN symbol <html> <head> <title></title> <style> .ButtonStyle { background-color: red; cursor: pointer; font-weight: bold; color: white; } </style> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { $('#btnClickMe').on('click mouseover mouseout', function (event) { if (event.type == 'click') { $('#divResult').html('Button Clicked at ' + 'X = ' + event.pageX + ' Y = ' + event.pageY); } else if (event.type == 'mouseover') { $(this).addClass('ButtonStyle'); } else { $(this).removeClass('ButtonStyle'); } }); $('#btnEnableMouseOverEffect').click(function () { $('#btnClickMe').on('mouseover', function () { $(this).addClass('ButtonStyle'); }); }); $('#btnDisableMouseOverEffect').click(function () { $('#btnClickMe').off('mouseover'); }); }); </script> </head> <body style="font-family:Arial"> <input id="btnClickMe" type="button" value="Click Me" /> <input id="btnEnableMouseOverEffect" type="button" value="Enable Mouse Over Effect" /> <input id="btnDisableMouseOverEffect" type="button" value="Disable Mouse Over Effect" /> <br /><br /> <div id="divResult"></div> </body> </html> In the example above we are binding a single anonymous function as the event handler for all the 3 events 1. click 2. mouseover 3. mouseout If you want to bind a different anonymous function, you could do so using the following syntax. $('#btnClickMe').bind({ click : function(event){ $('#divResult').html('Button clicked at X = ' + event.pageX + ' Y = ' + event.pageY); }, mouseover: function () { $(this).addClass('ButtonStyle'); }, mouseout : function () { $(this).removeClass('ButtonStyle'); } }); jQuery shorthand functions (.click, .mouseover, .mouseout etc.) call on() method behind the scenes. So far in this video series we have seen 3 different ways of binding event handlers in jQuery 1. Using jQuery shorthand functions (.click, .mouseover, .mouseout etc.) element.click(function () { ... }); 2. With jQuery version < 1.7, bind() method can be used element.bind('click', function () { ... }); 3. With jQuery version 1.7 or higher, on() method can be used. element.on('click', function () { ... }); According to jQuery.com, as of jQuery 1.7, the .on() method is the preferred method for attaching event handlers.

REACT JS TUTORIAL #5 - Javascript Events & Data Changes in React
 
07:27
Let's wrap up beginner React.js lessons with handling JS events and data changes in React.js. If you build a Reactjs app correctly, each component is able to be very "dumb"..it will only be aware of a few pieces of the application and can be reused in multiple places. If a component is only aware of the data it needs and the event(s) it needs to fire when things change, it can be extremely decoupled from the rest of the application and less prone to break as the React JS application changes over time.

jQuery add event handler to dynamically created element
 
09:15
Link for all dot net and sql server video tutorial playlists https://www.youtube.com/user/kudvenkat/playlists?sort=dd&view=1 Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/04/jquery-add-event-handler-to-dynamically.html In this video we will discuss, how to add event handlers to dynamically created elements. Let us understand this with an example. The following example, allows us to dynamically create new list item (li), attach a click event handler and add it to the unordered list (ul). This happens when you click "Add a New List Item" button. The problem with this approach is that we are binding a click event handler to every list item. This means if you have 500 list items, then there will be 500 event handlers in the memory and this may negatively affect the performance of your application. <html> <head> <title></title> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { $('li').on('click', function () { $(this).fadeOut(500); }); $('#btnAdd').on('click', function () { var newListItem = $('<li>New List Item</li>').on('click', function () { $(this).fadeOut(500); }); $('ul').append(newListItem); }); }); </script> </head> <body style="font-family:Arial"> <input id="btnAdd" type="button" value="Add a New List Item" /> <ul> <li>List Item</li> <li>List Item</li> </ul> </body> </html> A better way of doing the same from a performance standpoint is shown below. In this example, the click event handler is attached to the listitem (li) parent element (ul). Even if you have 500 list items, there is only one click event handler in memory. So how does this work 1. When you click on a list item (li), the event gets bubbled up to its parent (ul) as the list item (li) does not have an event handler 2. The bubbled event is handled by the the parent (ul) element, as it has a click event handler. 3. When a new list item is added dynamicaly, you don't have to add the click event handler to it. Since the newly created list item (li) is added to the same parent element (ul), the click event of this list item also gets bubbled upto the same parent and will be handled by it. <html> <head> <title></title> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { $('ul').on('click', 'li', function () { $(this).fadeOut(500); }); $('#btnAdd').on('click', function () { $('ul').append('<li>New List Item</li>'); }); }); </script> </head> <body style="font-family:Arial"> <input id="btnAdd" type="button" value="Add a New List Item" /> <ul> <li>List Item</li> <li>List Item</li> </ul> </body> </html>

Handling events in AngularJS
 
07:57
event handling in angularjs angularjs ng click example angularjs ng click event In this video we will discuss how to handle events in AngularJS. Let us understand with an example. Here is what we want to do. 1. Display the list of technologies in a table 2. Provide the ability to ike and dislike a technology 3. Increment the likes and dislikes when the respective buttons are clicked Script.js : In the controller function we have 2 methods to increment likes and dislikes. Both the functions have the technology object that we want to like or dislike as a parameter. var app = angular .module("myModule", []) .controller("myController", function ($scope) { var technologies = [ { name:"C#", likes:0, dislikes:0 }, { name: "ASP.NET", likes: 0, dislikes: 0 }, { name: "SQL", likes: 0, dislikes: 0 }, { name: "AngularJS", likes: 0, dislikes: 0 } ]; $scope.technologies = technologies; $scope.incrementLikes = function (technology) { technology.likes++; }; $scope.incrementDislikes = function (technology) { technology.dislikes++; }; }); HtmlPage1.html : Notice in the html below, we are associating incrementLikes() and incrementDislikes() functions with the respective button. When any of these buttons are clicked, the corresponsing technology object is automatically passed to the function, and the likes or dislikes property is incremented depending on which button is clicked. [!DOCTYPE html] [html xmlns="http://www.w3.org/1999/xhtml"] [head] [title][/title] [script src="Scripts/angular.min.js"][/script] [script src="Scripts/Script.js"][/script] [link href="Styles.css" rel="stylesheet" /] [/head] [body ng-app="myModule"] [div ng-controller="myController"] [table] [thead] [tr] [th]Name[/th] [th]Likes[/th] [th]Dislikes[/th] [th]Like/Dislike[/th] [/tr] [/thead] [tbody] [tr ng-repeat="technology in technologies"] [td] {{ technology.name }} [/td] [td style="text-align:center"] {{ technology.likes }} [/td] [td style="text-align:center"] {{ technology.dislikes }} [/td] [td] [input type="button" ng-click="incrementLikes(technology)" value="Like" /] [input type="button" ng-click="incrementDislikes(technology)" value="Dislike" /] [/td] [/tr] [/tbody] [/table] [/div] [/body] [/html] Styles.css : Styles for table, td and th elements table { border-collapse: collapse; font-family:Arial; } td { border: 1px solid black; padding: 5px; } th { border: 1px solid black; padding: 5px; text-align: left; } Link for all dot net and sql server video tutorial playlists https://www.youtube.com/user/kudvenkat/playlists?sort=dd&view=1 Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/11/handling-events-in-angularjs.html

Angular2 Event Binding

The following bindings that we have discussed so far in this video series flow data in one direction i.e from a component class property to an HTML element property. 1. Interpolation 2. Property Binding 3. Attribute Binding 4. Class Binding 5. Style Binding How about flowing data in the opposite direction i.e from an HTML element to a component. When a user performs any action like clicking on a button, hovering over an element, selecting from a dropdownlist, typing in a textbox etc, then the corresponding event for that action is raised. We need to know when user performs these actions. We can use angular event binding to get notified when these events occur. For example the following is the syntax for binding to the click event of a button. Within parentheses on the left of the equal sign we have the target event, (click) in this case and on the right we have the template statement. In this case the onClick() method of the component class is called when the click event occurs. [button (click)="onClick()"]Click me[/button] With event binding we can also use the on- prefix alternative as shown below. This is known as the canonical form [button on-click="onClick()"]Click me[/button] Event Binding Example : import { Component } from '@angular/core'; @Component({ selector: 'my-app', template: `[button (click)='onClick()' ]Click me[/button]` }) export class AppComponent { onClick(): void { console.log('Button Clicked'); } } Every time we click the button, 'Button Clicked' message is logged to the console. You can see this message under the Console tab, in the browser developer tools. Another Example : Initially when the page loads we want to display only the First Name and Last of Employee. We also want to display "Show Details" button. When we click "Show Details" button, we want to display "Gender" and "Age" as well. The text on the button should be changed to "Hide Details". When we click "Hide Details" button, "Gender" and "Age" should be hidden and the button text should be changed to "Show Details". To achieve this we will make use of event binding in Angular. We will also make use of one of the structural directives "ngIf" in angular. Code in employee.component.ts : Notice we have introduced "showDetails" boolean property. The default value is false, so when the page first loads, we will have "Gender" and "Age" hidden. We also have a method, toggleDetails(), which toggles the value of showDetails. import { Component } from '@angular/core'; @Component({ selector: 'my-employee', templateUrl: 'app/employee/employee.component.html', styleUrls: ['app/employee/employee.component.css'] }) export class EmployeeComponent { columnSpan: number = 2; firstName: string = 'Tom'; lastName: string = 'Hopkins'; gender: string = 'Male'; age: number = 20; showDetails: boolean = false; toggleDetails(): void { this.showDetails = !this.showDetails; } } Code in employee.component.html : Notice the click event of the button is binded to toggleDetails() method To dynamicall change the text on the button, we are using ternary operator - {{showDetails ? 'Hide' : 'Show'}} Details We used ngIf structural directive on "Gender" and "Age" [tr] elements The * prefix before a directive indicates, it is a structural directive Besides ngIf, there are other structural directives which we will discuss in our upcoming videos The ngIf directive conditionally adds or removes content from the DOM based on whether or not an expression is true or false If "showDetails" is true, "Gender" and "Age" [tr] elements are added to the DOM, else removed

addeventlistener and removeeventlistener in JavaScript
 
11:51
Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/01/addeventlistener-and.html In this video we will discuss assigning event handlers in JavaScript using the following special methods addEventListener removeEventListener attachEvent detachEvent Internet Explorer 9 (and later versions) & all the other modern browsers support addEventListener() and removeEventListener() methods. Sytnax for assigning event handler using addEventListener() method element.addEventListener(event, handler, phase) Sytnax for removing event handler using removeEventListener() method element.removeEventListener(event, handler, phase) Please note : The third parameter phase is usually set to false as it is not used. Example : In this example, we are passing values for all the 3 parameters including phase. [input type="button" value="Click me" id="btn"/] [script type="text/javascript"] btn.addEventListener("mouseover", changeColorOnMouseOver, false); btn.addEventListener("mouseout", changeColorOnMouseOut, false); function changeColorOnMouseOver() { this.style.background = 'red'; this.style.color = 'yellow'; } function changeColorOnMouseOut() { this.style.background = 'black'; this.style.color = 'white'; } [/script] Since the third parameter "phase" is optional you can omit it if you wish. btn.addEventListener("mouseover", changeColorOnMouseOver); btn.addEventListener("mouseout", changeColorOnMouseOut); Example : This example demonstrates removing event handlers. [input type="button" value="Click me" id="btn"/] [input type="button" value="Remove Event Handlers" onclick="removeEventHandlers()" /] [script type="text/javascript"] btn.addEventListener("mouseover", changeColorOnMouseOver); btn.addEventListener("mouseout", changeColorOnMouseOut); function changeColorOnMouseOver() { this.style.background = 'red'; this.style.color = 'yellow'; } function changeColorOnMouseOut() { this.style.background = 'black'; this.style.color = 'white'; } function removeEventHandlers() { btn.removeEventListener("mouseover", changeColorOnMouseOver); btn.removeEventListener("mouseout", changeColorOnMouseOut); } [/script] Using this approach you can assign more than one event handler method to a given event. The order in which handler methods are executed is not defined. In this example, 2 event handler methods (clickHandler1 & clickHandler3) are assigned to click event of the button control. When you click the button both the handler methods are executed. [input type="button" value="Click me" id="btn"/] [script type="text/javascript"] btn.addEventListener("click", clickHandler1); btn.addEventListener("click", clickHandler2); function clickHandler1() { alert("Handler 1"); } function clickHandler2() { alert("Handler 2"); } [/script] attachEvent() and detachEvent() methods only work in Internet Explorer 8 and earlier versions. Sytnax for assigning event handler using attachEvent() method element.attachEvent( "on"+event, handler) Sytnax for removing event handler using detachEvent() method element.detachEvent( "on"+event, handler) Example : This example will only work in Internet Explorer 8 and earlier versions. [input type="button" value="Click me" id="btn"/] [script type="text/javascript"] btn.attachEvent("onclick", clickEventHandler); function clickEventHandler() { alert("Click Handler"); } [/script] Cross browser solution : For the above example to work in all browsers, modify the script as shown below. [input type="button" value="Click me" id="btn"/] [script type="text/javascript"] if (btn.addEventListener) { btn.addEventListener("click", clickEventHandler); } else { btn.attachEvent("onclick", clickEventHandler); } function clickEventHandler() { alert("Click Handler"); } [/script]

Welcome all, we will see Events in JavaScript in Hindi. JavaScript Events Tutorial in Hindi.JavaScript's interaction with HTML is handled through events that occur when the user or the browser manipulates a page. Events are a part of the Document Object Model (DOM) Level 3 and every HTML element contains a set of events which can trigger JavaScript Code. When the page loads, it is called an event. When the user clicks a button, that click too is an event. Other examples include events like pressing any key, closing a window, resizing a window, etc. onclick onmouseover and onmouseout onkeydown script Script runs when key is pressed onkeypress script Script runs when key is pressed and released onkeyup script Script runs when key is released Guys, Please support my channel by SUBSCRIBE to my channel and share my videos in your Social Network TimeLines.
