I got this varible:
var things = $('#box li');
My problem is that the user can change the value in #box. So it contains x different li:s then my var things is not set anymore. How do I change this var? var things
is in my index.php
file. The place where the user changes the #box
is in my change.php
file, so I think It’s a bit harder.
Probably I duplicate but I dont know what to search so please direct me if you can.

Use getElementsByTagName
, which will return a live HTMLCollection
, which you can select again:
var things = $('#box')[0].getElementsByTagName("li") console.log($(things).toArray()) $('li').last().remove() //remove last li element console.log($(things).toArray())
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div id="box"> <ul> <li>a</li> <li>b</li> <li>c</li> </ul> </div>
