整理几个中开发常用的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(点击可查看效果)
navigateToURL(new URLRequest('http://52friends.com'), '_blank');
4.刷新浏览器 (点击可查看效果)
navigateToURL(new URLRequest("javascript:location.reload();"),"_self")
5.关闭浏览器 (点击可查看效果)
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;
? }
?
