Flex-12 very simple,basic but useful function source in Flex

This article comes from http://ntt.cc,Yes,let's share.
No.1 Copy content to clipboard拷贝到剪贴板:

System.setClipboard(strContent);

No.2 Clone an ArrayCollection复制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 );

No.3 Open URL:

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

No.4 Page reload页面重新载入,通过JS:

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

No.5 Close browse关闭页面,也是通过JS:

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

No.6 Set the background alpha to transparent on Alert window,这个是定义CSS:

Alert
{
modalTransparency:0.0;
modalTransparencyBlur:0;
}

No.7 Set random color随机颜色：

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

No.8 Trim left of white space

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);
 }

No.9 Trim right of white space

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);
}

No.10 Trim left and right of white space

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

AS3CoreLib里带了去空格的类，大家可以参考下。
No.11 get data type获取数据的类型:

getQualifiedClassName(data)

No.12 Generate check digits

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&lt;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;
}
