[Htmlunit-user] Problem with Javascript engine.
|
From: Shanbhag, G. <ga...@am...> - 2005-06-10 02:17:16

This looks more of a Rhino issue than a htmlunit issue.
I am having problems using the document element inside a iframe=20
through Javascript. Is there any workaround to this problem?
Thanks,
Gautam
Heres the code and the output contains the html I used.

Subject: Re: [Htmlunit-user] Problem using htmlunit/rhino with dom
I have no idea what you're trying to do but SimpleScriptable (and =
everything under the javascript package) is internal code. From the =
package.html:
"Classes in this package are specific for the javascript engine - users =
of HtmlUnit shouldn't need anything in this package."
Then there's the fact that creating a SimpleScriptable directly doesn't =
seem like it would do much good anyway (it should probably be an =
abstract class but since it isn't really public API...).
