我正在运行一个循环,将拇指从xml列表中拉入包含的movieclip。我想要做的是让拇指的父级动画片段在加载完成后淡入淡出,但我无法弄清楚如何在它加载后引用它。
我的代码(目前无法按照我想要的方式运行):
var vsThumb:articleBox;
var currentarticleX:Number = 0;
var articleLinkURL:String;
var articleImageURL:String;
var articleText:String;
var vsThumbLoader:Loader;
var next_x:Number;
next_x = 9;
var thumbAlphaTween:Tween;
var articlevsThumb:Array = new Array();
function loadarticleHeadlines():void
{
for (var i:int = 0; i < egarticleXml.articlelist.articleitem.length(); i++)
{
vsThumb = new articleBox();
vsThumb.alpha = 0;
vsThumbLoader = new Loader();
vsThumbLoader.load(new URLRequest(egarticleXml.articlelist.articleitem[i].articlethumbnail));
articleListContainter.addChild(vsThumb);
vsThumb.articleImage.addChild(vsThumbLoader);
vsThumb.articleTitle.text = egarticleXml.articlelist.articleitem[i].articletitle;
titleAutosize(vsThumb.articleTitle);
vsThumb.x = next_x;
next_x += 260;
articlevsThumb[i] = vsThumb;
vsThumbLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, showBox);
vsThumb.clickBtn.buttonMode = true;
}
function showBox(event:Event):void
{
thumbAlphaTween = new Tween(articlevsThumb[i],"alpha",None.easeNone,0,1,.25,true);
}
}
那么我如何回访加载器的父级,以便我可以淡入整个动画片段?我可以将变量传递给showBox函数吗?

articleitem.length()-1
),因为其作用域是外部函数loadarticleHeadlines
(每次迭代时它将增加1)。这可能就是你的代码无效的原因。该事件将在您的加载器的loaderInfo上触发,因此您可以使用event.target.loader.parent找到加载器的父级:
function loadarticleHeadlines() : void
{
for (var i:int = 0; i < egarticleXml.articlelist.articleitem.length(); i++)
{
vsThumb = new articleBox();
vsThumb.alpha = 0;
vsThumbLoader = new Loader();
vsThumbLoader.load(new URLRequest(egarticleXml.articlelist.articleitem[i].articlethumbnail));
articleListContainter.addChild(vsThumb);
vsThumb.articleImage.addChild(vsThumbLoader);
vsThumb.articleTitle.text = egarticleXml.articlelist.articleitem[i].articletitle;
titleAutosize(vsThumb.articleTitle);
vsThumb.x = next_x;
next_x += 260;
articlevsThumb[i] = vsThumb;
vsThumbLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, showBox);
vsThumb.clickBtn.buttonMode = true;
}
}
function showBox(event:Event):void
{
thumbAlphaTween = new Tween(event.target.loader.parent,"alpha",None.easeNone,0,1,.25,true);
}

您无需将变量传递给showBox
,使用target的Event属性来检索Loader
:
function showBox(event:Event):void
{
var li:LoaderInfo=LoaderInfo(event.target);
// be nice remove your listener when your are done
li.removeEventListener(Event.COMPLETE, showBox);
var ldr:Loader=li.loader; // here is your loader
// do whatever you want with loader
thumbAlphaTween = new Tween(articlevsThumb[i],"alpha",None.easeNone,0,1,.25,true);
}
