每天学一点 几个Flex常用功能代码

1、复制内容到系统剪贴板

System.setClipboard(strContent);

2、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   );
   

3、打开一个新浏览器窗口

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

4、刷新浏览器

navigateToURL(new URLRequest("javascript:location.reload();"),"_self")

5、关闭浏览器

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

6、 设置Alert 窗口的背景为透明

Alert 
    { 
    modalTransparency:0.0;  
    modalTransparencyBlur:0;
    }

7、取随机颜色

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

8、 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);
    }

9、清除字串右侧空格

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);
    }

10、 清除字串左右的空格

public function Trim(s : String):String 
    { 
      return LTrim(RTrim(s));
    }

11、获取数据类型

getQualifiedClassName(data)

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;
  }
