Cross Site JavaScript

[BomberMan2K]

Hi guys,
I've seen this javascript being embedded across different sites. Like google does with ti's adwords and google analytics.

I want my javascript code to be embedded in other sites as well, so they can get html code from me to be displayed at their site, according to the parameters they pass to me.

For example - let's say I have a database of names and passwords, and I wish to get the name as a parameter for my JS code, and it will print the password in the site where it was requested from.

Can any please help with this coding approach?

btw, I don't mean to use AJAX here - just plain Javascript.

Thanx.
Roman.

That's kind of tricky. It might be possible to use location.search to get the value of the query string sent to the JS file, but I don't know if that would work or not.

Ideally a pure JavaScript implementation should work like this, right?

<script src="[URL unfurl="true"]http://domain/script.js?user=soandso&action=profile"></script>[/URL]

There might be a way to parse the query string sent directly to the JavaScript file like that, but more likely you'll get the query string of the page that included the JavaScript.

You could do what Google AdSense does and do something along the lines of:

<script src="[URL unfurl="true"]http://domain/script.js">[/URL]
var user = "soandso";
var action = "profile";
</script>

Otherwise, the only other solution I can think of would be to use PHP or CGI as your JavaScript. i.e.

#!/usr/bin/perl -w

use CGI;
my $q = new CGI;

my $name = $q->param('name');
my $act  = $q->param('action');

print "Content-Type: text/javascript\n\n";
print qq~
// Your JavaScript Code Here
document.onLoad = myFunction();

function myFunction() {
   window.alert ("name: $name");
   window.alert ("action: $action");
}
~;

And then

<script src="[URL unfurl="true"]http://domain/script.cgi?name=soandso&action=profile"></script>[/URL]
