ปัญหาคือ ต้องการให้เวลาพิมพ์ , ลงในช่อง text แล้วให้พิมพ์ได้

function checkIE()
{
   var msg = "";
   var ver = getiever();
   if( ver> -1 )
   {
      if( ver>= 8.0 )
         msg = "8";
      else if( ver == 7.0 )
    	  msg = "7";
      else if( ver == 6.0 )
    	  msg = "6";
      else
    	  msg = "<6";
    }
   return msg;
}

function CharacterFormat(fld,e){
   var strCheck = ',,';

   var len = 0;
   if( ie == 8 )
   		var whichCode = e.keyCode;
   else	
   		var whichCode = (window.Event) ? e.which : e.keyCode;
   
   key = String.fromCharCode(whichCode); 
   
   if( whichCode == 8 || whichCode == 0  || whichCode == 13) { 
	
	}else{ 

	   key = String.fromCharCode(whichCode); 
	   if(strCheck.indexOf(key) != -1) return false;
	}
}
