  2.关闭浏览器

  navigateToURL(new URLRequest("javascript:window.close()"),"_self");

  3.打开一个新浏览器窗口

  navigateToURL(new URLRequest('http://ntt.cc'), '_blank');

  4.复制一个ArrayCollection

  //dummy solution( well, it works )

  var bar:ArrayCollection = new ArrayCollection();

  for each ( var i:Object in ac ){

  bar.addItem( i );

  }

  // fantastic ! //

  var bar:ListCollectionView = new ListCollectionView( ListCollectionView( ac ).list );

  5.复制内容到系统剪贴板

  System.setClipboard(strContent);

  6.清除子串左侧空格

  public function LTrim(s : String):String

  {

  var i : Number = 0;

  while(s.charCodeAt(i) == 32 || s.charCodeAt(i) == 13 || s.charCodeAt(i) == 10 || s.charCodeAt(i) == 9)

  {

  i++;

  }

  return s.substring(i,s.length);

}

7.设置Alert 窗口的背景为透明

  Alert

  {

  modalTransparency:0.0;

  modalTransparencyBlur:0;

  }

  8.获取取随机颜色

  lbl.setStyle('color', 0xffffff*Math.random());

  9.获取数据类型

  getQualifiedClassName(data)

  10.字符串右侧空格清除

  public function RTrim(s : String):String

  {

  var i : Number = s.length - 1;

  while(s.charCodeAt(i) == 32 || s.charCodeAt(i) == 13 || s.charCodeAt(i) == 10 ||s.charCodeAt(i) == 9)

  {

  i--;

  }

  return s.substring(0,i+1);

  }

  11.清除字串左右的空格

  public function Trim(s : String):String

  {

  return LTrim(RTrim(s));

  }

12.生成随机字符串.

  private function GenerateCheckCode():String

  {

  //init

  var ran:Number;

  var number:Number;

  var code:String;

  var checkCode:String ="";

  //get 4 radom

  for(var i:int=0; i< 4; i++)

  {

  ran=Math.random();

  number =Math.round(ran*10000); //get result like 0.1234

  if(number % 2 == 0)

  code = String.fromCharCode(48+(number % 10)); //0's ASCII code is 48

  else

  code = String.fromCharCode(65+(number % 26)) ; // A's ASCII code is 65

  checkCode += code;

  }

  return checkCode;

  }
