JavaScript: How to access an image in main doc from iframe

[armanic]

Please help on the following:

I have a document loaded in an IFRAME. In that document, I need in a JavaScript to access an image (having an ID) in the main document (the document including the IFRAME). What I want to do is to change the image source in the main document.

My question: what is the (DOM) code to access that image. Is the .referrer used here?

Thanks in advance, Arman

[CODE=javascript]window.frames['your_frame_nam e'].document.getEl ementById('img_ id')[/CODE]

Sorry, it's doesn't work.

I need in the IFRAME document the image in the parent. Thus, this refers to an image in the frame (at least, that's what I understand):

window.frames['your_frame_name'].document.getElementById('img_id').src

This also doesn't work:

window.parent.document.getElementById('img_id').src

Please help once more and explain why the above example is wrong.

Thanks, Arman

I can't tell what exactly what you are trying to do here, but this is how I'd do it.

window.frames['frame_name'].document.getElementById("the_id").src = parent.document.getElementById("the_image_id").src;

IE has given me trouble with that in the past so I had to do it like this.

var my_iframe = window.frames['frame_name'];
var the_src = parent.document.getElementById("image_id").src;
my_iframe.document.getElementById("the_iframe_image_id").src = the_src;

I hope this helps if not maybe I'm not understanding what you are trying to do. Good day,

Let me explain what I'm trying to do:

There is a document ("doc1") that contains an image ("img1") and an IFRAME ("iframe1") . In this IFRAME, a second document is loaded ("doc2").
In doc2, I want to change the source of img1 in doc1.

When doing this in doc1, the code will be:

function changeSrc()
  {
  document.getElementById("img1").src="any_image.gif"
  }

The question is how this code must be when it is located in doc2.

sorry for the misunderstandin g ... it should work with:

[CODE=javascript]parent.document .getElementById ('img1').src = 'any_image.gif' ;[/CODE]
assuming that the iframe is part of the doc1?

kind regards

Yes! This works.

Thank you for your help.
