Question

我正在使用as3在flash中构建一个站点。我在主页上实现了一个xml幻灯片，但在更改页面时它不会消失。任何人都可以告诉我如何在其他页面上删除它？

幻灯片代码：

import fl.transitions.Tween;
import fl.transitions.easing.*;
import fl.transitions.TweenEvent;

var my_speed:Number;
var my_total:Number;
var my_images:XMLList;

var my_loaders_array:Array = [];
var my_success_counter:Number = 0;
var my_playback_counter:Number = 0;

var my_slideshow:Sprite = new Sprite();
var my_image_slides:Sprite = new Sprite();
var my_timer:Timer;
var my_prev_tween:Tween;
var my_tweens_array:Array = [];

var my_xml_loader:URLLoader = new URLLoader();
my_xml_loader.load(new URLRequest("slideshow_home.xml"));
my_xml_loader.addEventListener(Event.COMPLETE, processXML);


function processXML(e:Event):void
{

var my_xml:XML = new XML(e.target.data);
my_speed = my_xml. @ SPEED;
my_images = my_xml.IMAGE;
my_total = my_images.length();

loadImages();

my_xml_loader.removeEventListener(Event.COMPLETE, processXML);
my_xml_loader = null;

}

function loadImages():void
{
for (var i:Number = 0; i < my_total; i++)
{

    var my_url:String = my_images[i]. @ URL;
    var my_loader:Loader = new Loader();
    my_loader.load(new URLRequest(my_url));
    my_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete);
    my_loaders_array.push(my_loader);

}
}

function onComplete(e:Event):void
{

my_success_counter++;
if (my_success_counter == my_total)
{

    startShow();

}

var my_loaderInfo:LoaderInfo = LoaderInfo(e.target); 
my_loaderInfo.removeEventListener(Event.COMPLETE, onComplete);

}

function startShow():void
{

addChild(my_slideshow);
my_slideshow.addChild(my_image_slides);

nextImage();
my_timer = new Timer(my_speed*5000);
my_timer.addEventListener(TimerEvent.TIMER, timerListener);
my_timer.start();

}

function nextImage():void
{

var my_image:Loader = Loader(my_loaders_array[my_playback_counter]);
my_image_slides.addChild(my_image);
my_image.x = (stage.stageWidth - my_image.width)-160;
my_image.y = (stage.stageHeight - my_image.height)-100;
new Tween(my_image,"alpha",Strong.easeOut,0,1,1,true);
my_tweens_array[0] = new Tween(my_image,"alpha",Strong.easeOut,0,1,1,true); 

}

function timerListener(e:TimerEvent):void
{
hidePrev();


my_playback_counter++;
if (my_playback_counter == my_total)
{
    my_playback_counter = 0;
}
nextImage();

}

function hidePrev():void
{

var my_image:Loader = Loader(my_image_slides.getChildAt(0));
my_prev_tween = new Tween(my_image,"alpha",Strong.easeOut,1,0,1,true);
my_prev_tween.addEventListener(TweenEvent.MOTION_FINISH, onFadeOut);
}

function onFadeOut(e:TweenEvent):void
{
my_image_slides.removeChildAt(0);

}

Answer 1

my_slideshow.visible = false;

使用此功能，您可以隐藏幻灯片。

但这是愚蠢的方式，因为幻灯片仍然在后台运行。

如果您使用类级别程序，您可以使用removechild方法非常轻松地从舞台中删除幻灯片。这种方式很棒。

Answer 2

将此作为单独的类，然后在主时间轴中实例化。这样您就可以轻松删除。
