如何处理\捕获此错误

Unhandled IOErrorEvent:. text=Error #2124: Loaded file is an unknown type.

我尝试使用AS3将损坏的图像加载到MovieClip中我试过用try＆amp;抓住但没办法我也尝试addEventListener

loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, onIOError);

但它没有发现此错误

任何帮助？！

如果要捕获任何看不见的错误，可以使用标准的try-catch块。

var ldr:Loader = new Loader();
ldr.contentLoaderInfo.addEventListener("complete", ldrDone);
ldr.contentLoaderInfo.addEventListener("ioError", ldrError);
ldr.load(new URLRequest("FILE-NAME-COMES-HERE"));

function ldrDone(evt:*):void
{
    //if the file can be loaded into a Loader object, this part runs
    var temp:*;

    try
    {
        temp = evt.target.content;
        //add it to the stage
        stage.addChild(temp);

        //this traces whether the loaded content is a Bitmap (jpg, gif, png) or a MovieClip (swf)
        var classOfObject:String = flash.utils.getQualifiedClassName(temp);
        trace(classOfObject);
    }
    catch(error:*)
    {
        trace("some error was caught, for example swf is AS2, or whatever, like Error #2180");
    }
}

function ldrError(evt:*):void
{
    //if the file can't be loaded into a Loader object, this part runs
    trace("this is the error part, Error #2124 won't show up");
}

这会捕获错误，例如您尝试加载的swf是一个旧的swf（与AS2一起发布） - 错误＃2180。

如果找不到文件，或者看起来不是任何可加载格式，则运行ioError部分 - 错误＃2124。
