我有一个内置于 Flash cs5 中的 Adobe Air 桌面留言板应用程序,它在动态文本字段中加载一个外部“.txt”文件,并每 2 分钟检查一次新文件。我需要它来通知用户(NotificationType.CRITICAL),只有当文件是新的,而不是每次加载它时。是否可以?
应用程序中的所有代码:
NativeApplication.nativeApplication.startAtLogin=true
stage.nativeWindow.alwaysInFront=true;
//external text file load and recheck every 2 minutes
var myInterval:uint = setInterval (loadUrl, 120000);
var loader:URLLoader = new URLLoader(new URLRequest("https://my_text_file.txt"));
loader.addEventListener(Event.COMPLETE, completeHandler);
function completeHandler(event:Event):void {
var loadedText:URLLoader = URLLoader(event.target);
if(myText_txt.htmlText!=loadedText.data){
myText_txt.htmlText = loadedText.data;
stage.nativeWindow.notifyUser(NotificationType.CRITICAL)
}else {
//do nothing
}
}
function loadUrl():void {
loader = new URLLoader(new URLRequest("https:///my_text_file.txt"));
loader.addEventListener(Event.COMPLETE, completeHandler);
}
// button control
Minimize_BTN.addEventListener(MouseEvent.CLICK, minimize);
function minimize(e:MouseEvent){
stage.nativeWindow.minimize();
}
drag_BTN.addEventListener(MouseEvent.MOUSE_DOWN, drag);
function drag(e:MouseEvent){
stage.nativeWindow.startMove();
}
stop(); //Stop on the frame you want
