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 < 6; i++){ 
        if (addrParts[i] == \'\'){ 
             alert(\'error\'); 
             return false; 
        } 
   } 

   if (addrParts[i].length != 2) { 
        alert(\'error\'); 
        return false; 
   } 
   for (j = 0; j < addrParts[i].length; j++) { 
        c = addrParts[i].toLowerCase().charAt(j); 
        if ((c >= \'0\' && c <= \'9\') || (c >= \'a\' && c <=\'f\')) { 
             continue; 
        } else { 
             alert(\'error\'); 
             return false; 
        } 
   } 

   if ((parseInt(addrParts[0], 16) % 2) == 1) { 
        alert(\'error\'); 
        return false; 
   } 

   return true;
