IP地址验证和排序

验证IP地址正则：

/^((25[0-5]|2[0-4]\d|[01]?\d\d?)($|(?!\.$)\.)){ 
   4}$/

IP地址排序（按照大小）：

           var aryIP =['192.168.12.11','192.168.12.131','192.168.12.33','192.168.11.33','192.168.2.33'];
            aryIP.sort(function(a,b){ 
   
                var intA ;
                var intB ; 
                var aryA = a.split('.');
                var aryB = b.split('.');
                $.each(aryA,function(i){ 
   
                    aryA[i] = prefixInteger(aryA[i], 3);
                });
                $.each(aryB,function(i){ 
   
                    aryB[i] = prefixInteger(aryB[i], 3);
                });
                intA = aryA.join('')-0;
                intB = aryB.join('')-0;
                return intA-intB;
            })
            function prefixInteger(num, n) { 
   
                return (Array(n).join(0) + num).slice(-n);
            }
            console.log(aryIP);
