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)
