jQuery Dynamic Click Event:  Bind click event on dynamically added element HTML tags. Here this article explains how to add click event for dynamic added element. In jQuery for click event we can simply use .click() method which works fine, but when we add dynamic HTML and try to achieve click event for it, then there we face problem .i.e jQuery .click() is not working.

Yeah you are right .click() is not working because it's not loaded on DOM, so now what we are going to do is we use .on() method which is added in jQuery v 1.7.

The .on() method attaches event handlers to the currently selected set of elements in the jQuery object.

Prototype : .on( events [, selector ] [, data ], handler )

Description: Attach an event handler function for one or more events to the selected elements.

Example 1: Click event for dynamically added li tags

HTML Markup:  Here we have UL list tag and then we dynamically add LI tag. So now how to achieve click event on this dynamically added element in jQuery.

<ul id="myUL">
 <li>One</li>
 <li>Two</li>
   .......
   .......
</ul>

Here myUL- is the id which is already available on DOM when the page loads.

jQuery: Now by using .on() will able to bind the click event on dynamically added HTML tag .i.e click event for dynamic added Li tags.

$('#myUL').on('click','li', function(){
    console.log('you clicked me');
});

 Example 2: jQuery click event for dynamically added row and divs .i.e tr 

HTML Markup:  Here we have HTML table, and dynamically tr table rows get added, so now we want to bind click event for dynamic added tr table rows using jQuery .on() method

<table id="myTable">
<tr><td>row 1 col 1</td><td>row 1 col 2</td></tr>
<tr><td>row 2 col 1</td><td>row 2 col 2</td></tr>
   .......... 
   ..........
</table>

jQuery : Here myTable is my table id, and on each dynamically added tr we can bind click event as shown in below code.

$('#myTable').on('click','tr', function() {
  alert( $( this ).text() );
});

// Same for div 
// Note: .itemName is the class of dynamically added element under parent div container .i.e myDIv
$('#myDiv').on('hover','.itemName', function() {
   alert( $( this ).text() );
});

Here myDiv - is parent Div id,  .itemName- each span which have itemName call will alert its data.

View Demo

Here in the demo we successfully add dynamic rows to our HTML table .i.e, myTable with some dummy data and a select button. On button click we alert the selected table row data.

For older jQuery library  - 1.7

We can use .live() (method is deprecated in 1.7 and removed in 1.9)

Prototype : .live(events, handler )

Description: Attach an event handler for all elements which match the current selector, now and in the future.

//*
$('#myUL li').live('click', function() {
  alert('hello!'); 
});
//*

 Note:  Use of the .live() method is no longer recommended since later versions of jQuery offer better methods that do not have its drawbacks.
