How to set document.domain for a dynamically generated IFRAME?
- by Paras Chopra
I am implementing CodeMirror (http://marijn.haverbeke.nl/codemirror/) on a page where document.domain needs to be declared (because of other IFRAMES on the page).
CodeMirror generates a dynamic IFRAME to provide syntax highlighted code editing. The problem is that IE throws up 'Access Denied' (other browsers are fine) at the following piece of code mirror code:
this.win = frame.contentWindow;
...
var doc = this.win.document; <-- ERROR
doc.open();
doc.write(html.join(""));
doc.close();
It turns out IE doesn't inherit document.domain from parent IE. I can set document.domain in the IFRAME contents but IE throws up the error before I can even set the contents. Any ideas how to tackle this problem?
