Cross Domain Data JQuery Plugin

Plugin can be used to dynamically load content from same or other domains. It can also
post form data to remote server script.
It’s creating a hidden iframe object to fetch remote page and when remote page sends data
(either via window.postMessage in all modern browsers or via window.name in IE 6 & 7),
data is read and callback method is invoked.

Simple usage:

Only to retrieve data:

$.getRemoteData(
function(data){
$("body").append( data );
},
'http://-some-remote-url-/source.html'
);

To post form use it like this:

$.postFormRemote(
function(data){
$("#form_result").append( data );
},
'form_id', 'form_url', 'form_method'
);

In source page one must add code like this (as last body element),
to enable true cross domain interaction:

<script type="text/javascript">
window.name = $("body").html();
try {
var target = parent.postMessage ? parent : (parent.document.postMessage ? parent.document : undefined);

if (typeof target != "undefined") {
target.postMessage($("body").html(), "*");
}
} catch (e) {/**/}
</script>
