I need to access document object of document inside an IFRAME. Is there a way to do that for IE7 and IE8?

I need to get the scrollHeight property of the document inside the <iframe>. I tried all the opti开发者_C百科ons which are:

contentWindow.document  
contentDocument  
window.frames  

All these works fine for IE9,chrome and FF. But i couldnot get it to work in IE7 and IE8.

If anyone has a solution that would be great.

thanks

try out :

contentWindow.documentElement.document

Try this

<script>
    var iframe_doc = "window.document.getElementById('your_iframe_id').document";
    iframe_doc = eval(iframe_doc);
</script>

The above code should return you the iframe document, then get the scrollHeight attribute of the iframe document.
