IFRAME autosizes and DIV autoload.

[alejandro.rivero]

In Mozilla, the following code seems to resize correctly the IFRAME,
so no scroll bars:

<iframe marginwidth=0 marginheight=0 src=text.html
onload="this.height=
this.contentDocument.height">
</iframe>

Of course a frameborder=0 can be desiderable too :-)

Also, the same trick simplifies DIV loading:

<div id=pie></div>
<iframe
onload="document.getElementById('pie').innerHTML=
this.contentDocument.body.innerHTML"
scrolling=no width=100% height=1% frameborder=0 style="visibility:hidden"
src=text.html>
here the this.innerHTML, which is not transferred
</iframe>

Regretly, the onload tag does not work in konqueror.

I get

Error: uncaught exception: Permission denied to get property HTMLDocument.height

when trying this with Mozilla (?)

Love to see it work though...

Hmm. Intriguing. My version of Mozilla is
Mozilla 1.4
Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030908 Debian/1.4-4

I have a page (http://cgt.unizar.es/jornadas/) with the resizing code in
an extended version, and it works:
<iframe
onload="this.height=this.contentDocument.height;
this.contentDocument.body.style.borderStyle='none';
this.contentDocument.body.style.marginTop=0;
this.contentDocument.body.style.marginBottom=0;
this.contentDocument.body.style.paddingBottom=0;
this.contentDocument.body.style.paddingTop=0;"
onclick="this.height= this.contentDocument.height"
scrolling=auto width=100% height=0 frameborder=0
src=punterosSL.html>
Tu browser no soporta iframes. Carga directamente el
<a href=punterosSL.html>fichero</a>
</iframe>

except for the onclick :-( But the onload does its work perfectly.
All the other stuff, btw, is just to avoid the vertical scroll bar nuissance.

DHTML and HTML are practically unrelated disciplines, please see
http://www.cs.tut.fi/~jkorpela/usenet/xpost.html. Also check out your
cross-site-scripting privleges. And use real properties:

this.setAttribute ( "height", this.contentDocument.
getElementsByTagName ( "body" ).item ( 0 ).
offsetHeight );

To handle this in Mozilla, style the content-documents:

:root {
overflow: moz-scrollbars-horizontal;
height: 100%;
}

Explorer has an overflow-x property to check. Both browsers support
adding these styles by force.

Tapping into iframe events is badly supported in most browsers. Perhaps
You can pass the information from content-document to the surrounding
enviroment for wider browser support.

window.addEventListener ( "load", function () {
top.yourResizeFunction ( document.body.offsetHeight );
}, false );

Can anybody do this in IE ? (autosize an iframe that is).

Yeh, it only works for pages from the same domain. :(
