The following example displays the gpUrlLoader Class with an option to load a JSON file. Add the event listener, then call the init method with the url and the load type.
var ldr:gpUrlLoader = new gpUrlLoader();
ldr.addEventListener(Event.COMPLETE, jsonLoaded);
ldr.addEventListener(ProgressEvent.PROGRESS, onProgress);
ldr.addEventListener(gpUrlLoader.LOADERROR, ioError);
ldr.init('my_json.js', 'json');
function jsonLoaded(event:Event):void {
var json:Object = ldr.getJson();
}
function onProgress(event:Event):void {
trace(ldr.urlLoader.bytesLoaded);
}
function ioError(e:Event):void {
trace('Error loading file');
}
