auto setting iframe height
Posted on 2010-11-11
Hi,
I am really struggling to auto set the height of an iframe with variable content on a client site.
Can anyone suggest the best way, javasript enabled and not enabled?
I have tracked a few previous posts but with limited success.
Cheers

I have a div with an ID of frameContent but the frame content is being served by another source over which we have no control so there is nothing to go with. At the moment I just have to set the iframe height attribute to 1600px to avoid overflow but this just looks messy
use something like that
<iframe allowtransparency=true frameborder=0 id=rf scrolling=auto src="http://www.externaldomain.com/" style="width:100%;height:1
<iframe allowtransparency=true frameborder=0 id=rf scrolling=auto src="http://www.externaldomain.com/" style="width:100%;height:1
I have tried putting the height to 100% and 80% using the iframe attributes and the css but neither seem to work.
I am now using a blank test page with nothing else but the iframe and it defaults to about 150px with an autoscroll

Percentage height do NOT WORK on an iframe. They have to be REAL pixel heights. There is a method of autosetting the Iframe height, but I have not tried it, and can't say if it works or not. My experience is that these methods do not work for Iframes. The other error is to put an IFRAME in a DIV. Remove the DIV that encloses it, it does not mean anything to the iframe.
A DIV is a component element of a web page that interacts with other DIV components. An IFRAME is NOT this -- it is a separate PAGE in a PAGE -- think of it like a HOLE cut out in your page, where you see another web page underneath yours. How big do you cut the hole? AHA, that is the problem, it has to be defined.
To test for scalable code, check these -- try them to see if they work --

We tried to do this for a web application to go on a tv screen, but after days of hunting and looking for solutions we found nothing.
The simple fact is, the content you're displaying in the iframe is on a completely separate website, so unless you have access to change some code on the website being viewed.. it's not possible.
What you'd have to do is get the client website to send out the height, and your website read this value. There is no way of your website auto-detecting the height.
