Question

I have an application that will return JSON-P data, and I have been communicating with it using jQuery’s simple getJSON method:

$.getJSON("http://somedomain.com/&callback=?", this.callback);

I am bundling my code up into a library, and I love to not require jQuery. How easy would it be to re-write the getJSON function so that I can get cross-domain JSON-P data?

Answer 1

Can do something like

<script>
function mycallback(data) {
   //do something funky with 'data'
}

var oHead = document.getElementsByTagName('HEAD').item(0);
var oScript= document.createElement("script");
oScript.type = "text/javascript";
oScript.src="http://somedomain.com/&callback=mycallback";
oHead.appendChild( oScript);
</script>
