[DHTML] iFrame SSI IV

[HighContrast]

Give your iframes that you want excluded a class="exclude" attribute, and use this function sizeFrame in place of the existing one:

function sizeFrame(){
if(document.getElementsByTagName('frameset').length||!document.getElementsByTagName('iframe').length)
return;
var frEls=document.getElementsByTagName('iframe'), s='scrollHeight',
frObs=window.frames, o='offsetHeight', b='body', de='documentElement';
for (var cs, hb, hd, d='document', i = frEls.length-1; i > -1; --i)
if (!/exclude/.test(frEls[i].className)){
if(frObs[i][d][b].style.overflow)
cs=frObs[i][d][b].style.overflow;
frObs[i][d][b].style.overflow='hidden';
frEls[i].height=10;
frEls[i].height=Math.max(frObs[i][d][b][o], Math.max(frObs[i][d][de][o],
(hd=frObs[i][d][de][s]) != (hb=frObs[i][d][b][s])? Math.max(hd, hb):0))+
(frEls[i].height==frEls[i].offsetHeight&&frEls[i].getAttribute('frameborder',0)!=='0'?4:0);
frObs[i][d][b].style.overflow=typeof cs=='string'? cs : '';
};
if(!sizeFrame.setup){
for (var i = frEls.length-1; i > -1; --i)
if (!/exclude/.test(frEls[i].className))
sizeFrame.loadup(frEls[i]);
sizeFrame.setup=true;
}};

I´m sorry to wake up an old thread.

First of, thank you so much for this script! I've tried bunch of scripts and this is the only one that works on all browsers!

But since I don't know javascript I have one question.

I wonder if it's possible to make this code the other way around, so that only iframes with class="include" are resized.

Problem is that I have a chatbar (facebook look-a-like) that uses iframes. The chat windows don't expand correctly when I add this script to the site. I can't edit the code for the chatbar so I'm not able to add class="exclude" to the code.

I only need to resize one iframe so I was wondering if it would be possible to make this script only target that one frame.

Thank you.

Here's a quick guess. Save a backup of your page before trying this, but here's how I'd approach it:

Find all lines like this:
if (!/exclude/.test(frEls[i].className)){

I see two of them in the code you quoted above, and there might be more places.

Then replace them with this:
if (/include/.test(frEls[i].className)){

Or similar logic. The ! symbol means "not", so just remove the ! then change "exclude" to "include", and that should, I hope, work for you.
(In the case that you find "exclude" without !, then you might need to add one so it's !+include. I'm guessing you won't find that though.)

Works like charm

Thank you djr33!

This is still working to date but in IE9 it cuts the last line in half.
How can I get it to show the complete line.

Thanks

Could this be used in a wordpress site? I'm trying to get it running but without any luck. it seems to shrink the iframe to about 100 pixels every time.
