2、iFrame Auto Resize
About a month ago I was faced with the same need (to conditionally resize an iframe) and discovered that it just wouldn't work reliably due to browser quirks.
However, I solved the problem by creating a div in the parent page that got replaced with the innerHTML from the body of the document in the iframe. Worked like a charm.
You can use an onload event in the iframe element in the parent page or an onload event in the body of the document in the iframed page to trigger the exchange.
Post a stripped down version of the page if you can. One that shows exactly how the iframe fits into the structure of the page.
The solution I settled on works like this:
The parent page has a javascript function like this:
function insertIt() {
var _y = document.getElementById('framediv');
var _x = window.frames[0].document.body.innerHTML;
_y.innerHTML = _x
}
Then, the parent page has a div with the id "framediv" which is placed where the contents of the iframe should appear on the page.
The iframe element is then placed inside the div, like this:
<div id="framediv">
<iframe onload="insertIt();" src="/somewhere/content.htm" frameborder="no" width="555px" scrolling="no">
</div>
As you can see, there's onload="insertIt()" inside the iframe element. So when the iframe loads, the parent page immediately takes the contents of the body of the document contained in the iframe and actually replaces the iframe element with that content.
It's a little tricky to comprehend, but it works great.
You said you're a newbie, does this make any sense to you?
also, is the iframe document located on the same server and the same domain as the parent page?
That will play a part.
