The . click () events are only attach to fully loaded elements and can't use for dynamic added elements and utilize more memory and create event handler for each child. The .click() requires to event handler for all element which are attached. It is produce the overhead at time for DOM manipulations. The   .on( )  events are used for both dynamic added elements and its consume less memory then .click() events. It allows creating the event handler which elements are added dynamically ways. The .on() will work for current and future elements and it a replacement of the bind(), live() and delegate() methods. The Example over click() vs. on() in details as given below, For .click() events :- The HTML code, < ul   id ="click">      < li > List items </ li > </ ul > The JavaScript code, $( '#click li' ).click( function  () {     $( this ).parent().append($( '<li>New List i...

What is main difference between the $(document).ready () and window.onload()? The main differences are the $(document).ready() event called when your HTML document is loaded and DOM is ready and it's don't wait for your content and images etc. fully loaded but  window.onload() (<body onload="func();">) event is  wait for your content and images etc. fully loaded. The $(document).ready() function is called only one time when your page is loading not for partial page rendering in that case you need to use pageLoad() function. Document Ready function:- We can call more than one document.ready() function in single page. The  document.ready()  function is called when  DOM  is not fully loaded that means rest of images, css or other 3rd party reference on page. It will not wait for the images, css or other 3rd party to get loaded. Body Onload function:- The body.onload() function, we can have only one body.onload...

Advantages:- 1.       Minimal Data Transfer 2.       An asynchronous call by XMLHttpRequest  and it is hold and wait process. 3.       Reduce the traffic travels between the client and the server and the response time is faster so increases performance and speed. 4.       Better responsive and interactivity and faster page renders and improved response times. 5.       Supports almost all modern browsers. 6.       Easy Navigation. 7.       Open source JavaScript libraries available for AJAX support like JQuery, etc. Disadvantages:- 1.       Insecure and increment the load on web server. 2.       All files are downloaded at client-side. 3.       Browser compatibility issues accrued. 4.     ...

The  Asynchronous  Request non-blocking the client  DOM / browser  until your operations is completed and only initiates the operations. It is a backgrounds process.   It is not  hold  and  waits  process and it is an asynchronous call and the asynchronous calls do not wait for a response to close the socket. The Asynchronous call are using when requests are not depend to each other request’s responses. The callback server must be available or the response will be failed. The operations (send, receive, and reply) will be synchronous or asynchronous. By default, the  $.ajax  request in  jQuery  is set to asynchronous and we can set ( async :  false ) for synchronous operations otherwise ( async :  true ). For Synchronous request click...     Example – AJAX Asynchronous Call //AJAX Synchronous and Asynchronous Requests. //#REGION NAMESPACE var demo = demo || {}; //...
