Actionscript 3 as3鼠标向下定时器

我想知道一种方法可以检测鼠标id在项目上停留的时间，并且像一个检查器一样，检查鼠标id在特定项目上停留的时间。可以使用定时器吗

非常感谢

当然，但您不需要计时器：

import flash.utils.getTimer;

var startTime:int = 0;
var endTime:int = 0;

function SomeFunctionOrClassConstructor():void
{
    item.addEventListener(MouseEvent.MOUSE_DOWN, startMouseDown, false, 0, true);
}

function startMouseDown($evt:MouseEvent):void {
    startTime = getTimer();
    item.removeEventListener(MouseEvent.MOUSE_DOWN, startMouseDown);
    item.addEventListener(MouseEvent.MOUSE_UP, endMouseDown, false, 0, true);
}

function endMouseDown($evt:MouseEvent):void {
    endTime = getTimer();
    item.addEventListener(MouseEvent.MOUSE_DOWN, startMouseDown, false, 0, true);
    item.removeEventListener(MouseEvent.MOUSE_UP, endMouseDown);
    trace(endTime - startTime);
}

这应该可以让你开始了。

    trace(endTime - startTime);
}
