JavaScript: document.iframe.link.click() ?

[Scoochi2]

Hey, I'm trying to get JS to simulate a link click in an iframe on my page. Normally I would just change the src of the iframe, but the link I need to click contains a code that is different each time, and will not work with a different (or no) code.

I have this:

<iframe width='600' height='400' id='iframe' name='iframe' src='page.php'></iframe>

and my JS thus far is this:

document.getElementById('iframe').links[25].click();

However, that gives the error:

Error: document.getElementById("iframe").links is undefined
Source File: http://localhost/codeswitcher
Line: 49

I have tried using document.iframe.links... as well but get a similar result.

Does anyone know where I'm going wrong or have a better way to 'click' that link? Manually clicking the link is out of the question, as this script will be run many times in succession and I don't want to stay up all night .

I've also tried using the following.

frames['iframe'].document.links[25].click();

However, that gives the error: "Permission denied to get property Window.document".

EDIT: I now realise that I cannot do this due to the iframe containing a site from a different domain to my own. This is an entirely different problem
