Given an HTML document and the task is to replace an HTML element by another element. For example: we can change an element <b> with <h1> element without changing any other property.
Approach:
- Select the HTML element which need to be change.
- Copy all attributes of previous element in an object.
- Replace the previous element by new element.
Example 1: This example illustrates the above approach.
html
<!DOCTYPE HTML>
<html>
<head>
<title>
JQuery | Change an element type.
</title>
<script src=
</script>
</head>
<body style = "text-align:center;">
<h1 style = "color:green;" >

</h1>
<p id = "GFG_UP" style =
"font-size: 15px; font-weight: bold;">
</p>
<button onclick = "GFG_Fun()">
click here
</button>
<br><br>
<b style = "color:green; font-weight: bold;">
Welcome to GeeksforGeeks
</b>
<script>
var up = document.getElementById('GFG_UP');
up.innerHTML = "Click on the button to "
+ "replace an HTML element";
function GFG_Fun() {
var attribute = { };
$.each($("b")[0].attributes, function(id, atr) {
attribute[atr.nodeName] = atr.nodeValue;
});
$("b").replaceWith(function () {
return $("<h1 />",
attribute).append($(this).contents());
});
}
</script>
</body>
</html>
|
Output:
- Before clicking on the button:
- After clicking on the button:
Example 2: This example using the above discussed approach but with a different way to copy attributes.
html
<!DOCTYPE HTML>
<html>
<head>
<title>
JQuery | Change an element type.
</title>
<script src=
</script>
</head>
<body id = "body" style = "text-align:center;">
<h1 style = "color:green;" >

</h1>
<p id = "GFG_UP" style =
"font-size: 15px; font-weight: bold;">
</p>
<button onclick = "GFG_Fun()">
click here
</button>
<br><br>
<b style =
"color:green; font-weight: bold;">
Welcome to GeeksforGeeks
</b>
<script>
var up = document.getElementById('GFG_UP');
up.innerHTML = "Click on the button to "
+ "replace an HTML element";
function GFG_Fun() {
var oldElement = $("b");
var newElement = $("<h1>");
for(var i=0; i<oldElement[0].attributes.length; i++) {
var Attr = oldElement[0].attributes[i].nodeName;
var AttrVal = oldElement[0].attributes[i].nodeValue;
newElement.attr(Attr, AttrVal);
}
newElement.html(oldElement.html());
oldElement.replaceWith(newElement);
}
</script>
</body>
