jquery inside Bootstrap modal

I'm using jquery code to check for duplicates in a database as the user types an email address in a field.  The code works fine until I place the field inside a Bootstrap modal.

Here's the jquery function
    <script type="text/javascript"> //Check if family email address has already been used.
	$(document).ready(function() {
    var x_timer;    
    $("#f_email").keyup(function (e){
        clearTimeout(x_timer);
        var f_email_var = $(this).val();
        x_timer = setTimeout(function(){
            check_f_email_ajax(f_email_var);
        }, 1000);
    });

function check_f_email_ajax(f_email){
    $("#user-result").html('<img src="ajax-loader.gif" />');
    $.post('/support/check_f_email.php', {'f_email':f_email}, function(data) {
      $("#user-result").html(data);
    });
}
});
</script>

Open in new window


Here's the form code 
<div id="registration-form">
  <label for="f_email">Enter f_email :
  <input name="f_email" type="text" id="f_email" maxlength="45"> <span id="user-result"></span>
  </label>
</div>

Open in new window


The page is here..

http://testregister.cenational.org/cc/dashboard.php

You'll see at the top a field where the jqery call works--when you finish typing, the database is dup-checked for the email address.  But when you click 'Add Family' you'll see a field called 'Enter f_email' that doesn't work.

Thanks for any help give,

I suspect your problem is with event binding.  The way in which you're binding is only binding to elements that exist on the page at the point in time when this code runs:

$("#f_email").keyup(function (e){

}

Open in new window


Try using "on", which will bind elements that are dynamically added to a page.

$("#f_email").on("keyup",function (e){

}

Thanks for the suggestion, I do appreciate the help.  I inserted your code, but still don't get the function to work inside the modal.

Put a console log inside the jQuery function to verify it's triggering.  If it's not triggering, then please post the HTML for the modal, including the div or whatever that contains the modal.

It didn't trigger.  Here's the HTML for the modal.  But if it's not triggering, would this code even have a chance to run?

    <div class="container">
  <!-- Trigger the modal with a button -->
	<td colspan="1"><button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Add Family</button></td>

  <!-- Modal -->
  <div class="modal fade" id="myModal" role="dialog">
    <div class="modal-dialog">
    
      <!-- Modal content-->
      <div class="modal-content">
        <div class="modal-header">
          <button type="button" class="close" data-dismiss="modal">&times;</button>
          <h4 class="modal-title">Add Family</h4>
          Email, first and last name are required.  Other information will need to be filled out by the family contact.

You must have something else going on then.  Because the code you posted works fine and triggers the jQuery event when I type.  Here is a Fiddle Demo

demo result
For the demo, I just copied your code directly, and added the jQuery:
$('#f_email').on('keyup', function() {
  console.log('hello world');
});
