JSONPject

Takes a JSONP script (one that has a callback=) in the query string and a callback and provides a new script URL specifiying a new callback which wraps the passed in callback. The included script will call the provided callback, ensuring your callback is only called when the JSONP script has finished loading.

Usage

This sort of assumes you're using something to let you use CommonJS modules on the browser end.

var jsonpject = require('jsonpject');
 
function my_callback(data){
    do_something_with(data);
}
 
var jsonp = jsonpject('http://test.com/a_script.js?callback=?');
window[jsonp.fn_name] = jsonp.fn;
var scr = document.createElement('script');
scr.src = jsonp.url;
document.head.appendChild(scr);

Testing

Uses grunt to do testing. Test is available from npm
