javascript: Cross Domain Request for IE8+

ms-xdr.js

// Get weather for charlotte using YQL + Yahoo weather
var xdr = new XDomainRequest();

xdr.onload = function() {
	// the string now looks like..  json = { ... };
    json = 'json = ' + xdr.responseText; 
    // json is now a regular JSON object
    eval(json); 
    // parse using same function as for jQuery's success event
    self.draw(json.query.results.item.forecast, $elem); 
}
/* 
This is insane ... If all the handlers(especially onprogress)aren't set, the xdr in IE9 randomly aborts :(
