Flex常用AS

 

Flex里面常需要用到方法，很实用

No.1  拷贝内容到剪贴板

System.setClipboard(strContent);

No.2 拷贝 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 打开一个网页链接:

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

No.4 刷新当前页面（网页）:

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

No.5 关闭浏览器:

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

No.6 设置弹出窗口的背景透明度:

Alert
{
modalTransparency:0.0;
modalTransparencyBlur:0;
}

No.7 设置控件的颜色为一个随机的颜色：

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

No.8 去除字符串左边的空格

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);
}

No.9 去除字符串右边的空格

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

); }

No.10 去除字符串左右两边的空格

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

No.11 获取数据类型:

getQualifiedClassName(data)

No.12 产生一个随机验证码：

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;
}
