Let me preface this with... I have referenced this question/answers and it seems to contain clues, but i'm still missing the whole picture

Run JQuery in the context of another frame

Essentially, the structure of the index page is this

<html>
<body>
  <div class="frames-wrap">
      <iframe id="this-iframe" src="location.php">

      </iframe>
  </div>
</body>
</html>

location.php then contains a frameset (ahem, not my idea...) that has two frames that are set up like so...

<frameset cols="350,*">
  <frame src="search.php" id="frame_search" name="search"/>
  <frame src="edit.php" id="frame_edit" name="edit" />
</frameset>

if i want to manipulate objects between the index page and these elements how would i go about this?

I keep thinking the context should be something similar to window.parent.frames[0].document... what else am i missing?

I think the link from technicolorenvy has the answer, but the selector has a lesser known second parameter where you can set the context.

Something like this:

var iframeDoc = document.getElementById('myIframe');
iframeDoc = (iframeDoc.contentWindow) ? iframeDoc.contentWindow : (iframeDoc.contentDocument.document) ? iframeDoc.contentDocument.document : iframeDoc.contentDocument;


// From the parent window
$('p', iframeDoc).html('Hello from parent');

Preface: You wont be able to access the iframes contents unless it originates from the same domain.

To select elements in your iframe you could use a jQuery call like this

element = $("#this_iframe").contents().find("#frame_search")

The key is to use the contents() function. See Traversing/contents

Giving your frames ids that are valid JavaScript identifiers would help, then you could use constructs such as window.top.this_iframe.frame_edit.document as your context.

  • thanks for the feedback! however, this is bombing for me. the ids now have underscores rather than ndashes. if i use console.log to see what's happening "behind the scenes" it will return something if i log window.top.this_iframe.document OR if i log window.top.document.getElementById('this_iframe') so it appears that the frame_edit id is not being "seen". any ideas? – technicolorenvy Jan 27 '10 at 23:52

These were all helpful. I kept bombing when I was attempting to get past the iframe in the DOM. THis would appear to be from the fact i had code residing in the ready() method, but the frameset that was being called within the iframe was not loaded by the time that had $(document).ready() fired.

Thanks for all the great help and feedback!
