1.实现FLex点击下载：
private function onWmDownload(event:MouseEvent):void{
?? ?var urlRequest:URLRequest=new URLRequest('data/tangshan/download/hellotangshan.CAB');
?? ?urlRequest.method="POST";
?? ?urlRequest.contentType = 'application/octet-stream';
?? ?navigateToURL(urlRequest,"_blank");
}
2.实现loading效果：
public var dataLoading:DataLoading;
public var isDataLoadingShowing:Boolean = false;
public function showDataLoading():void{
?? ?if(isDataLoadingShowing)return;
?? ?dataLoading = new DataLoading();
?? ?PopUpManager.addPopUp(dataLoading,this,true);
?? ?PopUpManager.centerPopUp(dataLoading);
?? ?isDataLoadingShowing = true;
}
public function removeDataLoading():void{
?? ?PopUpManager.removePopUp(dataLoading);
?? ?isDataLoadingShowing = false;
}
实现细节：在click事件响应函数中加入showDataLoading(),在callback中removeDataLoading()
