验证规则：
1. broadcast mac address (ff:ff:ff:ff::ff:ff:)
2. ipv4 & ipv6 multicast mac address
3. numeric character

复制代码 代码如下:
function isvalidmacaddress(address) { 
   var c = ''; 
   var i = 0, j = 0;
if ((address.tolowercase() == 'ff:ff:ff:ff:ff:ff') || (address.tolowercase() == '00:00:00:00:00:00')) { 
         alert('error'); 
         return false; 
   }
var addrparts = address.split(':'); 
   if (addrparts.length != 6) { 
       alert('error'); 
        return false; 
   } 
   for (i = 0; i         if (addrparts[i] == ''){ 
             alert('error'); 
             return false;

        alert('error'); 
        return false; 
   } 
   for (j = 0; j         c = addrparts[i].tolowercase().charat(j);
