Change Iframe Content from Cached HTML?

Is there any way that I can change the content of iframe from a cached html string? I am not talking about iframe.Attrib开发者_如何学Pythonute["src"] = "url", but rather given a string of html and change the content.

An ugly workaround might be saving the html into a file and change iframe src to it. Any other ways? Maybe javascript can help?

If you can control the contents of the iframe html, you could do something like this:

Expose a method as such:

<script type = "text/javascript">
function setData(str)
{
$('html').html(str);
}
</script>

and call it like

document.iFrameName.setData(myHtmlStr);

from the parent frame.

Stefan Kendall's solution is a good one. As a fallback, if you can't or don't want to use jQuery, you can also document.write into the iframe. Here's an example which I believe will eliminate all the cross-browser quirks.

Bearing in mind this must be on the same domain, otherwise you're into rpc territory...
