使用jQuery，你可以像這樣做，我刪除hidden所以你可以看到正在發生的事情。

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

<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>
