1，?复制内容到系统剪贴板

System.setClipboard(strContent);

2,复制一个ArrayCollection

Code
???//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

Code
?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

Code
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

Code
?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;
