Try it Yourself »

More "Try it Yourself" examples below.


Definition and Usage

The item() method returns a node at the specified index in a NodeList object.

The nodes are sorted as they appear in the source code, and the index starts at 0.

A Node object's collection of child nodes is an example of a NodeList object.

Note: There are two ways to access a node at the specified index in a node list:

This syntax:

document.body.childNodes.item(0);    // The first child node of <body>Try it

Will produce the same result as this syntax:

document.body.childNodes[0];         // The first child node of <body>Try it

You can use whatever method you like, however, the most common method is [index].

Tip: Use the length property to return the number of nodes in a NodeList object.
