I still can’t find out how JSONP is a workaround of Cross-Origin limitations. Do you mean that jQuery JSONP ajax instead of creating an XMLHttpRequest, simply creates an script tag and loads the result and passes it to the success callback function?

Great resource and well explained, Christpher. Just to clarify -you don’t need to use jQuery for a simple js script injection. Here’s the basic code fragment:

var script=document.createElement(’script’)
script.setAttribute(’src’,'http://www.yourdomain.com/yourscript.js’);
document.getElementsByTagName(‘head’)[0].appendChild(script);

In “yourscript.js” file you can do all your manipulations.

Thanks, your article is the last of all articles I’ve read to understand this JSONP thingy for days.

My mistake was I begun with understanding JSONP on jQuery,.. since it started off inside jQuery.Ajax() I thought this JSONP is actually an AJAX request, which confuses me in regards of same domain policy.
But now I finally found what I missed, that JSONP is NOT XHR request. starting from here (your article), I now can fully understand the examples. LOL.

Thanks.
