We know that cross domain ajax calls are not possible from javascript, but come’on we live in virtual world and every law can be bent if we can (remember Morpheus from ultra cool Matrix ;-) )

Ok, I found  here on this nice guy’s blog under Cross-Domain Communication with IFrames.

I have actually used it and it works like a charm. I made a simple javascript function to get the anchor values , actually I used anchors to pass values using URL as if passing URL variable.

For example if I want to pass one variable then I would do :

http://www.yourdomain.com#action=foo#

For two variables :

http://www.yourdomain.com#action=foo#action2=foo2#

Two JS function, one for getting anchor value and second for resetting URL to it’s original form.

function getAnchor(name) {

url = window.location.href;
var varlen = name.length + 2;
var start = url.indexOf(“#” + name) + varlen;
var length = url.indexOf(“#”, start) – start;

var value = url.substr(start, length);
return value;
}

function resetAnchor() {
url = window.location.href;
var hash = url.indexOf(“#”)
if (hash >= 0) {
url = url.substr(0, hash);
window.location.href = url + “#”;
}
}

I would be happy to help if you have any troubles.
