There are two alternative methods may perform operations on the label, replaceWith () and the replaceAll () method in jQuery:
replaceWith (): to replace all matching elements or specified HTML DOM elements.
replaceAll (selector): replace all selector matching element with a matching element.
In the following code, using the first tag selector acquires span, b, i tag, then call The replaceWith () method to replace h3 tag.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title></title>
<script src="js/jquery-3.3.1.js"></script>
</head>
<body>
<span>123</span>
<b>123</b>
<i>123</i>
<script>
$("span,b,i").replaceWith("<h3>HelloWorld</h3>");
</script>
</body>
</html>And this code is used to call the replaceAll h3 tag () method, passing jQuery object span, b, i is the label in the parameter list. Two programs operating results are as follows:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title></title>
<script src="js/jquery-3.3.1.js"></script>
</head>
<body>
<span>123</span>
<b>123</b>
<i>123</i>
<script>
$("<h3>HelloWorld</h3>").replaceAll("span,b,i");
</script>
</body>
</html>
