Using Javascript to submit a form at another URL

[Calab]

I have a website that requires the user to log in before they can access the
site. I'd like to be able to simply enter my URL and be logged into the
site. Unfortunately, the site does not support the format
http://username:password@URL

What I'd like to do is create a local file on my drive that will load the
site in question into an iframe. Once the page has finished loading, I'd
like javascript to populate the form fields and click the submit button. It
would be great if the page could end up loading as the top document, but I
could live with having my iframe set to 100% of the page size.

Is this possible? If so, how?

Thanks!

How can you login if you cannot access the site first?
The loginpage surely is not on anothere site??

What do you mean by "your url"?

That has nothing to do with a site, it simply is not a valid url on
modern(!) browsers, so your browser will not be able to do anything with
it.

You mean fake the login page of that site?

Sometimes that can be done, if the site builder is not testing the
session already being established.

However loading the login-page into an ifame will not help you.

Once the page has finished
loading, I'd like javascript to populate the form fields and click the
submit button.

Only on a faked page, not on the page of the site, as modern browsers do
not allow access to an iframe if cross domain.

the top document, but I could live with having my iframe set to 100%
of the page size.

Many impossible things would be great.

It's not something that a web site supports, but a browser. E.g.
Microsoft Internet Explorer only supported it up to version 6.0.

You can install a patch so that it works again for you.

Those form fields can only be approached when the parent page resides
on the same domain as the iframe; same for the submit-action.

Hope this helps,

One can as well use Internet Explorer 4.0, set the Security Level to Low and
be online with an account that has Administrator privileges. Or, why not
leave the default setting of sharing your C: partition with everyone else on
the Internet?

There has been a *security bugfix* for Internet Explorer 6 because the
`http:' URI scheme does not support authentication this way for good reasons.
