Question

我的老板要求我在我们的网站上添加年龄验证屏幕以便工作。

到目前为止，我有一个有效。但是，如果生日未满18岁，我需要将其重定向到Google，而不是说“你还不够老”（我只知道如何做到这一点）。

<head>

   <script language="javascript">
   function checkAge()
   {

   var min_age = 18;


   var year = parseInt(document.forms["age_form"]["year"].value);
   var month = parseInt(document.forms["age_form"]["month"].value) - 1;
   var day = parseInt(document.forms["age_form"]["day"].value);

   var theirDate = new Date((year + min_age), month, day);
   var today = new Date;

   if ( (today.getTime() - theirDate.getTime()) < 0) {
   alert("You are too young to enter this site!");
   return false;
   }
   else {

   return true;
   }
   }
   </script>
