The Node.normalize()
method 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
element.normalize();
Example
var wrapper = document.createElement("div"); wrapper.appendChild( document.createTextNode("Part 1 ") ); wrapper.appendChild( document.createTextNode("Part 2 ") ); // At this point, wrapper.childNodes.length === 2 // wrapper.childNodes[0].textContent === "Part 1 " // wrapper.childNodes[1].textContent === "Part 2 " wrapper.normalize(); // Now, wrapper.childNodes.length === 1 // wrapper.childNodes[0].textContent === "Part 1 Part 2 "
