I second this proposal. I'm attempting to write a Javascript file that
retrieves a web-page and parses the HTML. I plan to use it, for
example, to read my forum pages, extract post titles, and create an
message index.
I use an IFrame to retrieve the page, but then when I attempt to look
at the IFrame document.body, I get a
[quote]
ReferenceError message: Security error: attempted to read protected
variable
[/quote]
This is silly: I've already retrieved the page, it already appears in
the frame, I can see it on my screen, but Javascript is not allowed to
read it! I can open the page manually and view the source, but
Javascript is not allowed to see it! Why?! I fail to see how blocking
JavaScript access to IFrame content makes me more secure.
I wish there were a way to turn off this apparently useless "security
feature".
