Iframes and Extracting Content

[NigeW]

Hi there

I am working on a site that has an iframe. This iframe is retrieving data which is external to the website.

We want the iframe to resize based on the length of content within the iframe.

However as it is from an external source we cannot detect the length - browser security restrictions.

So one thought is :

1. Get the content of the iframe.
2. Copy content into a hidden iframe.
3. Detect the height of the hidden iframe.
4. Update the height of the visible iframe.

I cannot however find a way of extracting the content of the iframe.

Has anyone got any ideas ??

Thanks

can't you capture the iFrame.src.innerHTML.length?

Hey mwolf00

Thanks for the reply.

I tried your suggestion but couldn't get that to work - I tried different object references (document.getElementById('framename').src.innerHTML.length) but no luck.

I will follow this up when back at work on Friday.

BTW - awesome graphic in your signature - did you make it yourself ?

why are you trying to copy the content into a hidden frame?

Hi cLFlaVA

As detailed in my first post we cannot resize the iframe due to the src of the iframe being from a source external to the website. I haven't investigated the actual security risks behind it but we have not been able to successfully resize the iframe - there is always an "Access Denied" type message.

Therefore I thought I might be able to capture the content of the iframe, populate it into a hidden local iframe , calculate the size of the local iframe, and then resize the iframe with the remote data in it.
