12条有用的Flex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://52friends.com'), '_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;   }
