关于设计：Actionscript 载入外部文件与打印处理

7-1 显示动画影片的载入完成百分比

this.stop();
var ballArray=[ball1_mc,ball2_mc,ball3_mc,ball4_mc,ball5_mc,ball6_mc,ball7_mc,ball8_mc,ball9_mc,ball10_mc];
var myInfo:LoaderInfo=this.loaderInfo;

function chgBall(num){
 for (var i=0;i<num;i++){
  ballArray[i].gotoAndStop(2);
 }
}

this.addEventListener("enterFrame", initHandler);
function initHandler(event:Event){
 var myTbytes=myInfo.bytesTotal; 
 var myLoaded=myInfo.bytesLoaded;
 var percent = Math.floor(myLoaded / myTbytes * 100);
     msg_txt.text=percent + "%";
 if (percent>=100){
  //this.gotoAndStop(2);
  chgBall(10);
 }else if (percent>=90){
  chgBall(9);
 }else if(percent>=80){
  chgBall(8);
 }else if(percent>=70){
  chgBall(7);
 }else if(percent>=60){
  chgBall(6);
 }else if(percent>=50){
  chgBall(5);
 }else if(percent>=40){
  chgBall(4);
 }else if(percent>=30){
  chgBall(3);
 }else if(percent>=20){
  chgBall(2);
 }else if(percent>=10){
  chgBall(1);
 }
}

7-2 显示动画影片的载入状态（时间倒数，完成与总载入大小）

this.stop();
var myInfo:LoaderInfo=this.loaderInfo;

function setNum(num){
 return Math.round(num/1000);
}

this.addEventListener("enterFrame", initHandler);
function initHandler(event:Event){
 var myTbytes=myInfo.bytesTotal; 
 var myLoaded=myInfo.bytesLoaded;
 var percent = myLoaded/myTbytes;
 if (percent<=1){
  var time = (myTbytes-myLoaded)/(myLoaded/getTimer());
 }
 bar_mc.bar.scaleX=percent;
 total_txt.text=setNum(myTbytes);
 loaded_txt.text=setNum(myLoaded);
 time_txt.text=setNum(time) + "sec";
}

7-3 告知使用者外部文件的数据载入剩余量

var myLoader:Loader = new Loader();
 var url:String = "DSC_0249.JPG";
 var urlReq:URLRequest = new URLRequest(url);
 myLoader.load(urlReq);
 pic_mc.addChild(myLoader);
 
this.addEventListener("enterFrame", initHandler);
function initHandler(event:Event){
 var myInfo:LoaderInfo=myLoader.contentLoaderInfo;
 myLoaded=myInfo.bytesLoaded;
 myTbytes=myInfo.bytesTotal;
 remainNUM=Math.round((myTbytes-myLoaded)/1000);
 state_txt.text=remainNUM+"kb";
} 

7-4 载入外部文本文件

var word:URLLoader = new URLLoader(); 
var wordreq:URLRequest = new URLRequest("strawberry .txt");
word.load(wordreq);

word.addEventListener(Event.COMPLETE, onTEXTFileLoaded);
function onTEXTFileLoaded(me:Event){
       in_txt.text = word.data;
}
