I have a
element. How can remove all the elements inside it, except for the first and the last, using jQuery?
To remove from all ul-s on the page the li-s that are neither the first nor the last:
$('ul li:not(:first-child):not(:last-child)').remove();
Or using a specific id:
$('#yourul li:not(:first-child):not(:last-child)').remove();
If you have a jQuery object with your ul in it:
$(yourul).find('li:not(:first-child):not(:last-child)').remove();
Have you tried selecting all the list elements, and then removing the first and last ones from the list?
$('ul li').not('li:first, li:last').remove()
Here's a way to do it using slice
$("#removeAllButFirstAndLast").click(function() {
$("#myUL").children().slice(1, -1).remove()
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<ul id="myUL">
<li>first</li>
<li>second</li>
<li>third</li>
<li>fourth</li>
</ul>
<div id="removeAllButFirstAndLast">click to remove all but first and last</div>
$('ul li').not('li:first, li:last').remove();
This will remove all items from list Except/Exclude first and last element,
To remove all items from any list
$('#yourulid li').remove(); //remove all li items from list named/id #yourulid
$("ul li:not(:first-child):not(:last-child)").remove();
