使用JQuery你可以这样做，我删除了hidden，这样你就可以看到发生了什么。

＆＃13;

$('input[name="area[]"]').each(function(){
     $(this).attr('value',$(this).closest('ul').attr('location'));
})

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul id='sortlistThree' location='1' class='connectMe sort'>
  <li>
    <form class='sort'>
        <input name='area[]' class='dienstplan' data='getform' value='1' />
    </form>
  </li>
</ul>

<ul id='sortlistThree' location='2' class='connectMe sort'>
  <li>
    <form class='sort'>
        <input  name='area[]' class='dienstplan' data='getform' value='1' />
    </form>
  </li>
</ul>

<ul id='sortlistThree' location='3' class='connectMe sort'>
  <li>
    <form class='sort'>
        <input  name='area[]' class='dienstplan' data='getform' value='1' />
    </form>
  </li>
</ul>
