flex使用小技巧

//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)
