get contents of iframe

[markww]

I cannot get the contents of an iframe in my page, it is quickly
driving me insane. My iframe is defined like:

<iframe id = "e_body" name = "e_body" src="about:blank"></iframe>

I've made a function to retrieve the contents like:

function GetIFrameContentsPlease()
{
var strContents =
document.getElementById("e_body").document.body.innerHTML;

alert("the contents are: " + strContents);
}

but it fails. I need this to work on IE and FF, any suggestions?

Thanks

You realize you do need an actual source (-html document) in order to get
the contents of the iframe? I don't know if "about:blank" does it.

With that in mind, try this:

setTimeout("alert(e_body.document.body.innerHTML);",10);

Hi,

Yes there is no initial content, but the user is allowed to type in the
iframe with designMode = 'on' - I just need to get whatever they have
typed into the iframe. I'll give what you posted a try,

Thanks

If I understand you correctly you are using an IFRAME to get user input?
HTML already contains an element for such purpose, it is a FORM with a
TEXTAREA. Why the re-engineering?

Hi Jonathan,

I wanted to use an iframe so that the user could do some limited rich
text formatting, and I wouldn't have to script anything extra. I would
like there to be a button beneath the iframe such as 'edit' - in which
case the user can start typing in there, make text bold, type weblinks
like www.something.com. Then they could just hit 'stop edit', in which
case I'd just turn design mode 'off' and the weblinks they typed become
active, the rich text maintains its formatting, etc.

All I'd have to do is flip the designMode switch.

Textareas as I understand don't allow for such formatting or clickable
links?

Thanks

Many rich text widgets out there, here is one:
