Jquery click event not working after append method

JqueryHtml

Jquery Problem Overview


So I have this button which adds a new row to the table, however my problem is that it does not listen to the .new_participant_form click event anymore after the append method has taken place.

http://jsfiddle.net/cTEFG/

Click Add New Entry then click on the Form name.

$('#add_new_participant').click(function() {


    var first_name = $('#f_name_participant').val();
    var last_name = $('#l_name_participant').val();
    var role = $('#new_participant_role option:selected').text();
    var email = $('#email_participant').val();


    $('#registered_participants').append('<tr><td><a href="#" class="new_participant_form">Participant Registration</a></td><td>'+first_name+ ' '+last_name+'</td><td>'+role+'</td><td>0% done</td></tr>');

    });

    $('.new_participant_form').click(function() {

        var $td = $(this).closest('tr').children('td');

        var part_name = $td.eq(1).text();
        alert(part_name);

    });
});

HTML

<table id="registered_participants" class="tablesorter">

<thead>
<tr> 
<th>Form</th>
<th>Name</th>
<th>Role</th>
<th>Progress </th>


</tr> 
</thead>


<tbody>
<tr> 
<td><a href="#" class="new_participant_form">Participant Registration</a></td>
<td>Smith Johnson</td>
<td>Parent</td>
<td>60% done</td>


</tr> 
</tbody>
    
</table>

<button id="add_new_participant"></span>Add New Entry</button> 

Jquery Solutions


Solution 1 - Jquery

Use on :

$('#registered_participants').on('click', '.new_participant_form', function() {

So that the click is delegated to any element in #registered_participants having the class new_participant_form, even if it's added after you bound the event handler.

Solution 2 - Jquery

The .on() method is used to delegate events to elements, dynamically added or already present in the DOM:

// STATIC-PARENT              on  EVENT    DYNAMIC-CHILD
$('#registered_participants').on('click', '.new_participant_form', function() {

  var $td = $(this).closest('tr').find('td');
  var part_name = $td.eq(1).text();
  console.log( part_name );

});


$('#add_new_participant').click(function() {

  var first_name = $.trim( $('#f_name_participant').val() );
  var last_name  = $.trim( $('#l_name_participant').val() );
  var role       = $('#new_participant_role').val();
  var email      = $('#email_participant').val();
  
  if(!first_name && !last_name) return;

  $('#registered_participants').append('<tr><td><a href="#" class="new_participant_form">Participant Registration</a></td><td>' + first_name + ' ' + last_name + '</td><td>' + role + '</td><td>0% done</td></tr>');

});

<table id="registered_participants" class="tablesorter">
  <thead>
    <tr>
      <th>Form</th>
      <th>Name</th>
      <th>Role</th>
      <th>Progress </th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td><a href="#" class="new_participant_form">Participant Registration</a></td>
      <td>Smith Johnson</td>
      <td>Parent</td>
      <td>60% done</td>
    </tr>
  </tbody>
</table>

<input type="text" id="f_name_participant" placeholder="Name">
<input type="text" id="l_name_participant" placeholder="Surname">
<select id="new_participant_role">
  <option>Parent</option>
  <option>Child</option>
</select>
<button id="add_new_participant">Add New Entry</button>

Solution 3 - Jquery

This problem could be solved as mentioned using the .on on jQuery 1.7+ versions.

Unfortunately, this didn't work within my code (and I have 1.11) so I used:

$('body').delegate('.logout-link','click',function() {

http://api.jquery.com/delegate/

> As of jQuery 3.0, .delegate() has been deprecated. It was superseded > by the .on() method since jQuery 1.7, so its use was already > discouraged. For earlier versions, however, it remains the most > effective means to use event delegation. More information on event > binding and delegation is in the .on() method. In general, these are > the equivalent templates for the two methods:

// jQuery 1.4.3+
$( elements ).delegate( selector, events, data, handler );
// jQuery 1.7+
$( elements ).on( events, selector, data, handler );

This comment might help others :) !

Solution 4 - Jquery

TRY THIS

As of jQuery version 1.7+, the on() method is the new replacement for the bind(), live() and delegate() methods.

SO ADD THIS,

$(document).on("click", "a.new_participant_form" , function() {
      console.log('clicked');
});

Or for more information CHECK HERE

Solution 5 - Jquery

** Here is the solution, that might help you **

// Changed to delegate() method to use delegation from the body

$("body").delegate("#boundOnPageLoaded", "click", function(){
   alert("Delegated Button Clicked")
});

Solution 6 - Jquery

$(document).on("click", '.mylink', function(event) { 
alert("new link clicked!");});
