1.刷新浏览器   navigateToURL(new URLRequest("javascript:location.reload();"),"_self")   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;   }
