关于js校验

关于js校验判断字符传是否符合如下格式:  111,222,333,444  逗号分割的数字组合主要有两个小函数:<script>function isIntNumber(num) {     var type="^[0-9]*[1-9][0-9]*$";   var  re =  new   RegExp(type);   if(num.match(re)==null)    {     return false;   }   else   {  return true;   }     } function isOK(uids){         var uidArray = new Array();    uidArray = uids.split(',');        var flag=false;  for (var i=0;i<uidArray.length;i++)  {   alert("uid=="+uidArray[i]);   if (!isIntNumber(uidArray[i]))   {      flag=true;      break;   }  }           if(flag==true)           {                         return false;          }          else       {            return true;          }      }    // 测试:        alert(isOK("111,222,333"));       alert(isOK("111,aaa,333"));</script>
