Nice opens form

[orion_rus]

Hello world
I see an idea that's very interesting, but i didn't know how it happens may be somebody can explain it to me?
I see a link, and when i clicks it a form is shown. Link seems to be like what:

<a
href="http://passport.somesite/passport?mode=auth&amp;retpath=http://mail.somesite/"
onclick="return CheckSession('http://mail.somesite/');" class="enter"><img
src="http://img.somesiteru/i/i-enter.gif" border="0" height="13"
width="13">Enter mail</a>

It's very important to me
Thanks in advance

Any thing could be happening. We don't know what CheckSession does.

[orion_rus]

But CheckSession is JScript function or something else?

[Bernard Marx]

Yes, Javascript.
We're just looking into a black box at the moment.

Heh)) i didn't want to know what it did. I need to understand this mechanism what returns a Jscript funtion from another file. How it possible, syntax, and so on. May be any articles available about this effect?
