Resize IFRAME

[Jills]

Hi All,

Does anyone have any idea about how can we resize an IFRAME
dynamically according to its content from another domain? I want to
increase the height according to the page that is displayed on it.

Regards,
Jills

The document object representation of a page from a different domain
will be inaccessible and so it will not be possible to determine the
display dimensions of that document. Without that information it will
not be possible to alter the height of the IFRAME to match the height
of that document.

The original poster didn't mention how the iframe gets its new
content. When that instruction originates from the same domain as the
change of height, there is no problem:

<iframe id="ifr" height="100"></iframe>
<hr>
<input type="button" value="Google" onClick="
document.getElementById('ifr').src='http://www.google.com';
document.getElementById('ifr').height='200px';
">
<input type="button" value="Altavista" onClick="
document.getElementById('ifr').src='http://www.altavista.com';
document.getElementById('ifr').height='350px';
">
