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) 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; }
