CODE:

publicfunction 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++;
   }
   returns.substring(i,s.length);
}

9。清除字串右侧空格

CODE:

publicfunction 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--;
   }
   returns.substring(0,i+1);
}

10。清除字串左右的空格

CODE:

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

11。获取数据类型

CODE:

privatefunction 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 ASCIIcode is 48
     else
       code =String.fromCharCode(65+(number % 26)) ;      // A's ASCIIcode is 65
     checkCode += code;
   }
   return checkCode;
   }
