flash AS +xml 加载图片（使用MovieClipLoader实现LOADING）

该flash一共有两层，一层的第一帧用来添加要使用的按钮（btnPlay，btnBack）和动态文本框（其变量为ratio,note）；二层的第一帧用来添加AS（如下所示）：

stop();

//舞台设置为450*300；配置文件为configuration1.xml；

var doc = new XML();

sWidth = 450;

sHeight = 300;

doc.ignoreWhite = true;

myXML = null;

rootNode = null;

nodeNum = 0;

path = \"configuration1.xml\";

stopFlag = false;

overNum = 0;

totalWidth = 0;

posStr = \"\";

ratio = 0;

note = \"\";

tp = 1;

this.onLoad = function() {

doc.load(path);//加载xml文件。

};

doc.onLoad = function(success) {

if (success) {

myXML = doc.firstChild;

rootNode = myXML.firstChild;

node = rootNode;

k = 1;

while (node.nextSibling) {

_root[\"myload\"+k] = new MovieClipLoader();

_root[\"myListener\"+k] = new Object();

_root[\"myListener\"+k].onLoadStart = function(target_mc) {//加载开始时发生该事件

//trace(\"start \"+target_mc._parent._name);

};

_root[\"myListener\"+k].onLoadProgress = function(target_mc, loadedBytes, totalBytes) {//在onLoadStart和onLoadComplete之间的下载过程，要show loading效果的话，就要使用该事件。如果下载速度很快的话是看不到过程的哦。

_root.ratio = Math.round(loadedBytes/totalBytes*100);

_root.note = \"loading \"+target_mc._parent._name.substr(3, 1)+\"th pic\";

};

_root[\"myListener\"+k].onLoadInit = function(target_mc) {//MOVIECLIP被加载完毕后播放第一帧的时候发生该事件。

var tmpK = Number(target_mc._parent._name.substr(3, 1));

target_mc._parent._x = 30;

target_mc._parent._y = 30;

target_mc._parent._alpha = 0;

_root[\"pW\"+tmpK] = target_mc._width;

_root[\"pH\"+tmpK] = target_mc._height;

target_mc._parent._width = 450/_root[\"pH\"+tmpK]*300;

target_mc._parent._height = 200;

};

_root[\"myListener\"+k].onLoadError = function(target_mc, errorcode) {//加载过程发生错误时发生该事件

//trace(\"error\"+errorcode);

_root.note = target_mc._parent._name.substr(3, 1)+\"cann\'t be loaded!\";

};

_root[\"myListener\"+k].onLoadComplete = function(target_mc) {//加载过程完毕发生该事件。

var tmp = Number(target_mc._parent._name.substr(3, 1))+1;

_root.note = (tmp-1)+\"th pic \"+\"loaded!\";

_root[\"myload\"+tmp].loadClip(_root[\"urlForPic\"+tmp], _root[\"pic\"+tmp].picChild);

};

_root[\"myload\"+k].addListener(_root[\"myListener\"+k]);

_root.createEmptyMovieClip(\"pic\"+k, k*10);

_root[\"pic\"+k].createEmptyMovieClip(\"picChild\", k*100);//为什么要再创建一个空的movieclip呢，是因为只能使用被加载的movieclip（_root[\"pic\"+k].picChild）的_parent（_root[\"pic\"+k]）才能控制被加载的图片或swf的属性，如width和height，

_root[\"pic\"+k].picChild._x = 0;

_root[\"pic\"+k].picChild._y = 0;

_root[\"pic\"+k].onRollOver = function() {

_root.overNum = Number(this._name.substr(3, 1));

_root.stopFlag = true;

};

_root[\"pic\"+k].onEnterFrame = function() {

if (tp == Number(this._name.substr(3, 1)) && this._alpha<100) {

//if(tp==1)trace(this._alpha);

this._alpha = int(this._alpha+2);

} else if (this._alpha>0) {

this._alpha = int(this._alpha-2);

}

};

_root[\"pic\"+k].onRollOut = function() {

_root.stopFlag = false;

overNum = 0;

};

_root[\"pic\"+k].onRelease = function() {

getURL(_root[\"str\"+this._name.substr(3, 1)]);

};

_root[\"str\"+k] = node.nextSibling.attributes.url;

_root[\"txt\"+k] = node.nextSibling.attributes.des;

_root[\"urlForPic\"+k] = node.nextSibling.attributes.pic;

node = node.nextSibling;

k++;

}

} else {

trace(\"There was an error parsing the XML data\");

}

nodeNum = k-1;

_root[\"myload\"+1].loadClip(_root[\"urlForPic\"+1], _root[\"pic\"+1].picChild);

};

_root.btnPlay.onRelease = function() {

tp++;

if (tp>nodeNum) {

tp = 1;

}

};

_root.btnBack.onRelease = function() {

tp--;

if (tp<=0) {

tp = nodeNum;

}

};
