Question

我无法将eventListeners附加到我的数组中的元素，任何帮助/建议都会很棒..感谢阅读

   var urls:Array=["../showcaseThumbnails/1.jpg",
"../showcaseThumbnails/2.jpg",
"../showcaseThumbnails/3.jpg",
"../showcaseThumbnails/4.jpg",
"../showcaseThumbnails/5.jpg",
"../showcaseThumbnails/6.jpg"];
var loader:Loader;
for (var i:int=0;i<urls.length;i++)
{
   loader=startLoading(urls[i]);
   loader.y=510;
   loader.x=i*54+314;
   addChild(loader);
}

function startLoading(url:String):Loader
{
var loader:Loader=new Loader();
loader.load(new URLRequest(url));
return loader;
}

Answer 1

我猜你不需要再多一个阵列了。您可以使用loaderInfo的url属性来查找URL。

function onLoad(e:Event):void {
  var url:String = e.traget.url;
  var index:Number = urls.indexOf(url);
}

Answer 2

var urls:Array=["../showcaseThumbnails/1.jpg",
"../showcaseThumbnails/2.jpg",
"../showcaseThumbnails/3.jpg",
"../showcaseThumbnails/4.jpg",
"../showcaseThumbnails/5.jpg",
"../showcaseThumbnails/6.jpg"];

var loaders:Array = [];//array to store loaders
var loader:Loader;
for (var i:int=0;i<urls.length;i++)
{
   loader=startLoading(urls[i]);
   loaders.push(loader);
   loader.y=510;
   loader.x=i*54+314;
   addChild(loader);
}

function startLoading(url:String):Loader
{
   var loader:Loader=new Loader();
   loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoad);
   loader.load(new URLRequest(url));
   return loader;
} 
function onLoad(e:Event):void
{
   var index:Number = loaders.indexOf(LoaderInfo(e.target).loader);
   trace(urls[index]);
   //call the corresponding function from here based on index.
}
