The example in this article describes how jQuery uses the prepend() method to add content before elements. Share it with everyone for your reference. The specific analysis is as follows:

The following code can add new elements before text and lists

<!DOCTYPE html>
<html>
<head>
<script src="js/jquery.min.js">
</script>
<script>
$(document).ready(function(){
 $("#btn1").click(function(){
  $("p").prepend("<b>Prepended text</b>. ");
 });
 $("#btn2").click(function(){
  $("ol").prepend("<li>Prepended item</li>");
 });
});
</script>
</head>
<body>
<p>This is a paragraph.</p>
<p>This is another paragraph.</p>
<ol>
<li>List item 1</li>
<li>List item 2</li>
<li>List item 3</li>
</ol>
<button id="btn1">Prepend text</button>
<button id="btn2">Prepend list item</button>
</body>
</html>

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