The HTML DOM allows JavaScript to change the content of HTML elements.
Change the Value of an Attribute In the DOM, attributes are nodes. Unlike element nodes, attribute nodes have text values. The way to change the value of an attribute, is to change its text value. This can be done using the setAttribute() method or setting the nodeValue property of the attribute node.
To replace an element in an array:Use the indexOf() method to get the index of the element you want to replace. Call the Array. splice() method to replace the element at the specific index. The array element will get replaced in place.
by using replaceChild():
<html>
<head>
</head>
<body>
<div>
<a id="myAnchor" href="http://www.stackoverflow.com">StackOverflow</a>
</div>
<script type="text/JavaScript">
var myAnchor = document.getElementById("myAnchor");
var mySpan = document.createElement("span");
mySpan.innerHTML = "replaced anchor!";
myAnchor.parentNode.replaceChild(mySpan, myAnchor);
</script>
</body>
</html>
A.replaceWith(span) - No parent neededGeneric form:
target.replaceWith(element)
Way better/cleaner than the previous method.
For your use case:
A.replaceWith(span)
...).Examples:
// Initially [child1, target, child3]
target.replaceWith(span, "foo") // [child1, span, "foo", child3]
const list = ["bar", span]
target.replaceWith(...list, "fizz") // [child1, "bar", span, "fizz", child3]
null targetIf your target has a chance to be null, you can consider using the newish ?. optional chaining operator. Nothing will happen if target doesn't exist. Read more here.
target?.replaceWith?.(element)
child.before and child.after
parent.prepend and parent.append

var a = A.parentNode.replaceChild(document.createElement("span"), A);
a is the replaced A element.
This question is very old, but I found myself studying for a Microsoft Certification, and in the study book it was suggested to use:
oldElement.replaceNode(newElement)
I looked it up and it seems to only be supported in IE. Doh..
I thought I'd just add it here as a funny side note ;)
