I\'m writing a plugin for TinyMCE and have a problem with detecting click events inside an iframe.

From my search I\'ve come up with this:

Loading iframe:

In my case there were two jQuery's, for the inner and outer HTML. I had four steps before I could attach inner events:
1. wait for outer jQuery to be ready
2. wait for iframe to load
3. grab inner jQuery
4. wait for inner jQuery to be ready
```
$(function() {   // 1. wait for the outer jQuery to be ready, aka $(document).ready
    $('iframe#filecontainer').on('load', function() {   // 2. wait for the iframe to load
        var $inner$ = $(this)[0].contentWindow.$;   // 3. get hold of the inner jQuery
        $inner$(function() {   // 4. wait for the inner jQuery to be ready
            $inner$.on('click', function () {   // Now I can intercept inner events.
                // do something
            });
        });
    });
});
```
The trick is to use the inner jQuery to attach events. Notice how I'm getting the inner jQuery:
```
        var $inner$ = $(this)[0].contentWindow.$;
```
I had to bust out of jQuery into the object model for it. The $('iframe').contents() approach in the other answers didn't work in my case because that stays with the outer jQuery. (And by the way returns contentDocument.)

Just posting in case it helps someone. For me, the following code worked perfect:
```
$(document).ready(function(){
     $("#payment_status_div").hide();
     var iframe = $('#FileFrame').contents();
     iframe.find("#take_payment").click(function(){
         $("#payment_status_div").show("slow");
     });
});
```
Where 'FileFrame' is the iframe id and 'take_payment' is the button inside iframe. Since my form inside the iframe is posted to a different domain, when used load, I got an error message saying:

Blocked a frame with origin "https://www.example.com" from accessing a frame with origin "https://secure-test.worldpay.com". Protocols, domains, and ports must match.

I know this is old but the ID's don't match in your code one is choose_pic and one is choose_pics:
```
<input type=button id=choose_pics value='Choose'>

$("#filecontainer").contents().find("#choose_pic").click(function(){
    //do something      
}); 
```

I solved it by doing like this:

$('#filecontainer').load(function(){

        var iframe = $('#filecontainer').contents();

        iframe.find("#choose_pics").click(function(){
               alert("test");
        });
});

The tinymce API takes care of many events in the editors iframe. I strongly suggest to use them. Here is an example for the click handler

// Adds an observer to the onclick event using tinyMCE.init
tinyMCE.init({
   ...
   setup : function(ed) {
      ed.onClick.add(function(ed, e) {
           console.debug('Iframe clicked:' + e.target);
      });
   }
});
