//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.打開一個(gè)新瀏覽器窗口

復(fù)制代碼代碼如下:

navigateToURL(new URLRequest("http://www.5ga.cn"), "_blank");

4.刷新瀏覽器

復(fù)制代碼代碼如下:

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

5.關(guān)閉瀏覽器

復(fù)制代碼代碼如下:

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

6.設(shè)置Alert 窗口的背景為透明

復(fù)制代碼代碼如下:

Alert { 
modalTransparency:0.0; 
modalTransparencyBlur:0; 
} 

7.取隨機(jī)顏色

復(fù)制代碼代碼如下:

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

8.清除子串左側(cè)空格

復(fù)制代碼代碼如下:

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.清除字串右側(cè)空格

復(fù)制代碼代碼如下:

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

復(fù)制代碼代碼如下:

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

11.獲取數(shù)據(jù)類型

復(fù)制代碼代碼如下:

getQualifiedClassName(data) ;

12.生成隨機(jī)字符串.

復(fù)制代碼代碼如下:

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; 
}
