MovieClipLoader类与监听的应用

示例
以下示例举例说明如何使用多个 MovieClipLoader 方法和侦听器。

// 首先设置侦听器
var my_mcl = new MovieClipLoader();
myListener = new Object();
myListener.onLoadStart = function (target_mc) 
{
myTrace ("*********First my_mcl instance*********");
myTrace ("Your load has begun on movie clip .= " + target_mc);
var loadProgress = my_mcl.getProgress(target_mc);
myTrace(loadProgress.bytesLoaded + " = bytes loaded at start" );
myTrace(loadProgress.bytesTotal + " = bytes total at start");
}
myListener.onLoadProgress = function (target_mc, loadedBytes, totalBytes) 
{
myTrace ("*********First my_mcl instance Progress*********");
myTrace ("onLoadProgress() called back on movie clip " + target_mc);
myTrace(loadedBytes + " = bytes loaded at progress callback " );
myTrace(totalBytes + " = bytes total at progress callback \n");
}
myListener.onLoadComplete = function (target_mc) 
{
myTrace ("*********First my_mcl instance*********");
myTrace ("Your load is done on movie clip = " + target_mc);
var loadProgress = my_mcl.getProgress(target_mc);
myTrace(loadProgress.bytesLoaded + " = bytes loaded at end");
myTrace(loadProgress.bytesTotal + " = bytes total at end=");
}
myListener.onLoadInit = function (target_mc) 
{
myTrace ("*********First my_mcl instance*********");
myTrace ("Movie clip = " + target_mc + " is now initialized");
// 您现在可以进行所需的任何设置，例如：
target_mc._width = 100;
target_mc._width = 100;
} 
myListener.onLoadError = function (target_mc, errorCode) 
{
myTrace ("*********First my_mcl instance*********");
myTrace ("ERROR CODE = " + errorCode);
myTrace ("Your load failed on movie clip = " + target_mc + "\n");
 } 
my_mcl.addListener(myListener);
//现在将这些文件加载到其目标中。
// 加载到影片剪辑中 - 字符串用作目标
my_mcl.loadClip("http://www.somedomain.somewhere.com/someFile.swf","_root.myMC");
my_mcl.loadClip("http://www.somedomain.somewhere.com/someOtherFile.swf", "_level0.myMC2");
//失败的加载
my_mcl.loadClip("http://www.somedomain.somewhere.com/someFile.jpg", _root.myMC5);

   // 加载到影片剪辑中 - 影片剪辑实例用作目标。
my_mcl.loadClip("http://www.somedomain.somewhere.com/someOtherFile.jpg", _level0.myMC3);

   // 加载到 _level1 
my_mcl.loadClip("file:///C:/media/images/somePicture.jpg", 1); 
 
//第二次设置侦听器
var another_mcl = new MovieClipLoader();
myListener2 = new Object();
myListener2.onLoadStart = function (target_mc) 
{
myTrace ("*********Second my_mcl instance*********");
myTrace ("Your load has begun on movie clip22 .= " + target_mc);
var loadProgress = my_mcl.getProgress(target_mc);
myTrace(loadProgress.bytesLoaded + " = bytes loaded at start" );
myTrace(loadProgress.bytesTotal + " = bytes total at start");
}
myListener2.onLoadComplete = function (target_mc) 
{
myTrace ("*********Second my_mcl instance*********");
myTrace ("Your load is done on movie clip = " + target_mc);
var loadProgress = my_mcl.getProgress(target_mc);
myTrace(loadProgress.bytesLoaded + " = bytes loaded at end");
myTrace(loadProgress.bytesTotal + " = bytes total at end" );
} 
myListener2.onLoadError = function (target_mc, errorCode) 
{
myTrace ("*********Second my_mcl instance*********");
myTrace ("ERROR CODE = " + errorCode);
myTrace ("Your load failed on movie clip = " + target_mc + "\n");
 } 
another_mcl.addListener(myListener2);
//现在将这些文件加载到其目标中（使用 MovieClipLoader 的第二个实例）
another_mcl.loadClip("http://www.somedomain.somewhere.com/yetAnotherFile.jpg", _root.myMC4);
// 在完成下载以及已调用 my_mcl.onLoadInit 后
// 发出以下语句。
// my_mcl.removeListener(myListener)
// my_mcl.removeListener(myListener2)
