jQuery – Not selector example
In jQuery, the “not” is used to select all elements that do not match the selector.
Examples
- $(‘p:not(.class-p1)’) – selects all elements matched by <p> that do NOT have a class name of “class-p1”.
- $(‘li:not(:only-child)’) – selects all elements matched by <li> that are NOT the only child of their parent.
- $(‘li:not(:first-child)’) – selects all elements matched by <tr> that are NOT the first child of their parent.
jQuery Example

<title>jQuery not example</title>
<script type="text/javascript" src="jquery-1.3.2.min.js"></script>

<h1>jQuery not example</h1>
<ul class="class-ul">
<li>class-ul - #1</li>
<li>class-ul - #2</li>
<li>class-ul - #3</li>
<li>class-ul - #4</li>
<li>class-ul - #5</li>
</ul>
<ul id="id1">
<li>id1 - #1</li>
</ul>
<p class="class-p1">
class - #p1
</p>
<p class="class-p2">
class - #p2
</p>
<button>p:not(.class-p1)</button>
<button>li:not(:only-child)</button>
<button>li:not(:first-child)</button>
<script type="text/javascript">
$("button").click(function () {
var str = $(this).text();
$("li,p").css("background", "white");
$(str).css("background", "coral");
});
</script>
</body>
</html>
$(‘li:not(:first-child)’) – selects all elements matched by that are NOT the first child of their parent.
-> I think – selects all elements matched by that are NOT the first child of their parent.
In the line :-
$(‘li:not(:first-child)’) – selects all elements matched by that are NOT the first child of their parent.
shouldn’t it be instead of ?
