How to add content after the specified element in jquery
To add content after the specified element is to insert sibling elements after the specified element. jquery provides two methods:
after()
insertAfter()
after Both ( ) and insertAfter( ) can insert specified content after the selected element, but their operation objects are reversed. Let’s introduce it in detail below.

$(A).after(B) means inserting B after the outside of A.
Example:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<script src="js/jquery-3.2.1.min.js"></script>
<script>
$(document).ready(function() {
$("button").click(function() {
$("div").after("这是往div后面增加的新文本内容");
});
});
</script>
</head>
<body>
<div style="height:100px;background-color:yellow">
这是一些文本。
<p>这是div块中的一个p段落。</p>
</div><br>
<button>往div后面增加内容</button>
</body>
</html>
2. Use insertAfter()
$( A).insertAfter(B) means inserting A after the outside of B.
Example:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<script src="js/jquery-1.10.2.min.js"></script>
<script>
$(document).ready(function() {
$("button").click(function() {
$("<span style='color:pink;'>这是一个新增的span元素</span>").insertAfter("div");
});
});
</script>
</head>
<body>
