我正在将我的AS3代码库转换为TypeScript并遇到此错误:

AS3代码:

private function loadDataXml(assetsXml : String) : void {
    var loader : URLLoader = new URLLoader();
    loader.addEventListener(Event.COMPLETE, handleDataLoaded);
    loader.load(new URLRequest(assetsXml));
}

private function handleDataLoaded(event : Event) : void {
    var xml_data : XML = new XML(event.target.data);
    parseData(xml_data);
    .........
}

private function parseData(xml_data : XML) : void {
    ......
}

TypeScript代码

private loadDataXml(assetsXml : string) {
    var xmlRequest:XMLHttpRequest = new XMLHttpRequest();
    xmlRequest.addEventListener("load",this.handleDataLoaded, false);
    xmlRequest.open("GET", assetsXml, false);
    xmlRequest.setRequestHeader("Content-Type", "text/xml");
    xmlRequest.send(null);
}

private handleDataLoaded(evt:Event) {
    var xmlDoc:Document = (<XMLHttpRequest> evt.target).responseXML;
    this.parseXMLData(xmlDoc);
    ...... …
