Resizing iframe, not working in Firefox

Question

I'm trying to resize an iframe. My code is working in Chrome and Interner Explorer, but not in Firefox. Can someone explain why.

Here's my javascript:

<script type="text/javascript" language="javascript"> 

function autoResize(id){
var newheight;


if(document.getElementById){
    newheight=document.getElementById(id).contentDocument .body.scrollHeight;

}

document.getElementById(id).height= newheight;

}
</script>

And here is my iframe:

<iframe id="myframe" src="http://www.somesite.com/content/index.php" frameborder="0" scrolling="no" width="900px" onLoad="autoResize('myframe');"></iframe>

Are you getting any error here ? Give an alert here and see if you are actually getting the height in firefox .. — The Dark Knight, Feb 07 '13 at 11:36
Is www.somesite.com same-origin with your script? Is the web page in the subframe in quirks mode or standards mode? — Boris Zbarsky, Feb 07 '13 at 23:46

Maybe because you are not sending passing the id as parameter in function call in if statement. Try this:

<script type="text/javascript" language="javascript"> 

    function autoResize(id){

    if(document.getElementById(id)){
        document.getElementById(id).height = document.getElementById(id).contentDocument .body.scrollHeight;

    }
}
</script>

This also works with Chrome and IE, but not with Firefox (18.0.2). – user2050491 Feb 07 '13 at 14:01
