Extend function prototype to run a function as a WebWorker
Function.prototype.runOnBackgroundThread = function (aCallback) {
var _blob = new Blob(['onmessage = '+this.toString()],{"type":"text/javascript"});
var _worker = new Worker((webkitURL.createObjectURL || URL.createObjectURL)(_blob));
_worker.onmessage = aCallback;
_worker.postMessage();
}
var _test = function () {
postMessage((1+1).toString());
}
_test.runOnBackgroundThread(function(e){
alert(e.data);
});
