Trigger $document.ready (so AJAX code I can't modify is executed)

Afer some research i created a way to get it to work.

here is my test that shows it working: http://www.antiyes.com/test/test2.php

here is the relevant code:

<script>
    // easy copy of an array
    Array.prototype.copy = function() {
        return [].concat(this);
    };

    // this function is added to jQuery, it allows access to the readylist
    // it works for jQuery 1.3.2, it might break on future versions
    $.getReadyList = function() {
        if(this.readyList != null)
            this.myreadylist =  this.readyList.copy();      
        return this.myreadylist;
    };

    $(document).ready(function() {
        alert("blah");
    });

</script>

<script>

    // this should be added last so it gets all the ready event
    $(document).ready(function() {
        readylist = $.getReadyList();
    });

</script>

then in the body I have:

<input type="button" onclick="$(readylist).each(function(){this();});" value="trigger ready" />

basically what i did was add a function to jQuery that copies the readyList before it's cleared out, then it will be available to be used by you.

it looks like the code below doesnt work:

function AjaxLoaded() {
    $(document).trigger('ready');
}

drop the quotes around document.


Since the jQuery readyList is not exposed as of version 1.4 (discussed here) the nice solutions above are broken.

A way around this is by creating your own readyList, through overriding the original jQuery-ready method. This needs to be done before other scripts that use the original ready method are loaded. Otherwise just the same code as John/Kikito:

// Overrides jQuery-ready and makes it triggerable with $.triggerReady
// This script needs to be included before other scripts using the jQuery-ready.
// Tested with jQuery 1.7
(function(){
var readyList = [];

// Store a reference to the original ready method.
var originalReadyMethod = jQuery.fn.ready;

// Override jQuery.fn.ready
jQuery.fn.ready = function(){
if(arguments.length && arguments.length > 0 && typeof arguments[0] === 'function') {
  readyList.push(arguments[0]);
}

// Execute the original method.
originalReadyMethod.apply( this, arguments );
};

// Used to trigger all ready events
$.triggerReady = function() {
  $(readyList).each(function(){this();});
};
})();

I'm not sure whether it is advisable to override the ready method. Feel free to advise me on that. I have not yet found any side effects myself though.


Just in case anyone needs it, I refined John's solution a bit so it could be used directly as an included javascript file.

// jquery_trigger_ready.js
// this function is added to jQuery, it allows access to the readylist
// it works for jQuery 1.3.2, it might break on future versions
$.getReadyList = function() {
  if(this.readyList != null) { this.myreadylist = [].concat(this.readyList); }
  return this.myreadylist;
};

$(document).ready(function() {
  readylist = $.getReadyList();
});

$.triggerReady = function() {
  $(readylist).each(function(){this();});
}

Including this file after including jquery allows for triggering ready by invoking $.triggerReady(). Example:

<html>
  <head>
    <title>trigger ready event</title>
    <script src="test2_files/jquery-1.js" type="text/javascript"></script>
    <script src="jquery_trigger_ready.js" type="text/javascript"></script>
  </head>
  <body>
    <input onclick="$.triggerReady();" value="trigger ready" type="button">
    <script type="text/javascript">
      $(document).ready(function(){
          alert("blah");
      });
    </script>
  </body>
</html>

By the way, I wanted to make it $(document).triggerReady(). If anyone is willing to share some advice on that, ill be appreciated.
