jQuery implements the method of inserting a new element before the last element_jquery

The example in this article describes how jQuery implements inserting a new element before the last element. Share it with everyone for your reference. The details are as follows:

<script type="text/javascript"
src="http://ajax.microsoft.com/ajax/jquery/jquery-1.5.1.min.js">
</script>
<script type="text/javascript">
$(function () {
$("#btnOne").click(function () {
$('#divOne > p:last-child')
.before('<p>Dynamic Para</p>')
});
});
</script>

I hope this article will be helpful to everyone’s jquery programming design.
