iframe src as variable

[zbgump]

I hate asking questions when I know the answer is obvious, but here goes...


A friend of mine helped me out with a script to set a variable to the appropriate url for my iframe.


How do I set the src of the iframe to equal the variable, in the html body?


Thanks.

If you have

<iframe id="miFrame">

then you can

document.getElementById('miFrame').src = url;

Thanks for the re Gollum. I'm pretty new to javasript; I've been playing around with your recommendation and I'm just confusing myself further.


var iframe_url = ''

if (product.length > 0 ){

iframe_url = '/product_pages/set_pages/'+ product+ '.html ';

else

iframe_url = '/product_pages/set_pages/thing.html';



}




Thats part of the code I have to set "image_url".

Now for <iframe src = "X" > What goes where "X" is? Or am I going about this the wrong way still?

TIA

Looking over the post, I'm not sure I've been clear.

The varible gets set in the head of the page; depending on wether or not a variable string is attached to the url.




I need that variable to set which url is loaded in to my iframe.

in your document body...

<script type="text/javascript">
document.write('<iframe src="' + iframe_url + '"></iframe>');
</script>
