The operating environment of this tutorial: windows7 system, jquery1.10.2 version, Dell G3 computer.

In jQuery, if we want to replace node elements, we use the replaceWith() method and replaceAll() method to achieve it.

Method 1: Use replaceWith()

In jQuery, we can use the replaceWith() method to replace the selected element with another element.

Syntax:

$(A).replaceWith(B)

means replacing A with B. Note: Both A and B must contain HTML tags

Example:

<!DOCTYPE html>
<html>

	<head>
		<meta charset="UTF-8">
		<script src="js/jquery-1.10.2.min.js"></script>
		<script>
			$(function() {
				$("button").click(function() {
					$("p").replaceWith("<div><b>Hello world!</b></div>")
				})
			})
		</script>
	</head>
	<body>
		<p>这是一个段落。</p>
		<p>这是另一个段落。</p>
		<br><button>将p节点替换为div节点</button>
	</body>
</html>

In jQuery, although the two methods replaceAll() and replaceWith() have similar functions, they both replace an element with another element, but their operation objects are reversed.

means replacing B with A.

Example:

<!DOCTYPE html>
<html>

	<head>
		<meta charset="UTF-8">
		<script src="js/jquery-1.10.2.min.js"></script>
		<script>
			$(function() {
				$("button").click(function() {
					$("<div style=&#39;color:red;&#39;>Hello world!</div>").replaceAll("p");
				})
			})
		</script>
	</head>
	<body>
		<p>这是一个段落。</p>
		<p>这是另一个段落。</p>
		<br><button>将p节点替换为div节点</button>
