Question

我有一个菜单弹出，同时隐藏在按钮上的鼠标点击事件上，但我希望能够通过单击菜单movieclip及其按钮外部来隐藏所述菜单。是否有可能在as3中实现这一目标？

到目前为止，这是我找到，改编并尝试使用的解决方案，但仍然无法实现。

switchbd_btn.addEventListener(MouseEvent.CLICK, onClickHandler);
stage.addEventListener(MouseEvent.CLICK, onClickHandler);

function onClickHandler(event : MouseEvent) : void  {
            switch(event.target)
            {
                case switchbd_btn:
                    switchbd.gotoAndStop(2);
                    switchbdIN.start();
                    switchbd_btn.filters = [ONf];
                    break;

                case stage:
                    switchbdOUT.start();
                    switchbd.gotoAndStop(3);
                    switchbd_btn.filters = [OFf];
                    break;
            }
}

我原来的工作代码： -

//////////////////////SWITCH BOARD\\\\\\\\\\\\\\\\\\\\\\\\\\\\
switchbd_btn.addEventListener(MouseEvent.MOUSE_DOWN, ShowswitchBD);
var switchbdIN:Tween = new Tween (switchbd, "x", Strong.easeOut, 1089.05, 277.85, 1, true);
var switchbdOUT:Tween = new Tween (switchbd, "x", Strong.easeOut, 277.85, 1089.05, 1, true);
var ONf:DropShadowFilter = new DropShadowFilter (-1,26,0xCCCCCC,1,2,2,1,3,false,false,false);
var OFf:DropShadowFilter = new DropShadowFilter (6,26,0x000000,1,2,2,1,3,false,false,false);

function ShowswitchBD(e:MouseEvent):void {

    if (switchbd.currentFrame != 2)
    {
        switchbd.gotoAndStop(2);
        switchbdIN.start();
        switchbd_btn.filters = [ONf];
}
    else {
        switchbdOUT.start();
        switchbd.gotoAndStop(3);
        switchbd_btn.filters = [OFf];
    }
}

switchbd是菜单movieclip，switchbd_btn是按钮。

这是一种完成你所要求的模式。这假定您的菜单movieClip被调用：switchbd并使用按钮显示/隐藏它：switchbd_btn。

首先，在按钮上添加一个单击侦听器并创建处理函数：

switchbd_btn.addEventListener(MouseEvent.CLICK, toggleMenu);

function toggleMenu(e:Event):void {
    //the x position should be 277.85 when visible
    if(switchbd.x <= 278){
        hideMenu();
    }else{
        showMenu();
    }
}

现在创建节目和隐藏菜单功能：

function showMenu():void {
    switchbd.gotoAndStop(2); //or however you 'show' it

    switchbdIN.start();
    switchbd_btn.filters = [ONf];

    //since the menu is visible, listen for global mouse clicks to hide it
    stage.addEventListener(MouseEvent.CLICK, hideMenuGlobalClick);
}

function hideMenu():void {
    switchbd.gotoAndStop(3);
    switchbdOUT.start();
    switchbd_btn.filters = [OFf];

    //stop listening for global mouse clicks since the menu is hidden now
    stage.removeEventListener(MouseEvent.CLICK, hideMenuGlobalClick);
}

function hideMenuGlobalClick(e:Event):void {
    var target:DisplayObject = e.target as DisplayObject;

    //crawl up the display tree from the item click until there is no parent (stage)
    while(target && target.parent){
        //if the target is the menu or button, exit this function
        if(target == switchbd || target == switcbd_btn){
            return;
        }

        //move on to the next item up the chain
        target = target.parent;
    }

    //if you made it this far, it wasn't the menu that was clicked
    hideMenu();
}

点击外面隐藏菜单
