Node: normalize() method

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The normalize() method of the Node interface puts the specified node and all of its sub-tree into a normalized form. In a normalized sub-tree, no text nodes in the sub-tree are empty and there are no adjacent text nodes.

Syntax

js
normalize()

Parameters

None.

Return value

None.

Example

html
<output id="result"></output>
js
const wrapper = document.createElement("div");

wrapper.appendChild(document.createTextNode("Part 1 "));
wrapper.appendChild(document.createTextNode("Part 2 "));

let node = wrapper.firstChild;
let result = "Before normalization:\n";
while (node) {
  result += ` ${node.nodeName}: ${node.nodeValue}\n`;
  node = node.nextSibling;
}

wrapper.normalize();

node = wrapper.firstChild;
result += "\n\nAfter normalization:\n";
while (node) {
  result += ` ${node.nodeName}: ${node.nodeValue}\n`;
  node = node.nextSibling;
}

const output = document.getElementById("result");
output.innerText = result;
