HTMLCollection: item() method
The HTMLCollection method item()
returns the element located at the specified offset into the collection.
[!NOTE] Because the contents of an
HTMLCollectionare live, changes to the underlying DOM can and will cause the position of individual elements in the collection to change, so the index value will not necessarily remain constant for a given element.
Syntax
item(index)
Parameters
index- : The position of the
Elementto be returned. Elements appear in anHTMLCollectionin the same order in which they appear in the document’s source.
- : The position of the
Return value
The Element at the specified index, or null if
index is less than zero or greater than or equal to the length property.
Usage notes
The item() method returns a numbered element from an
HTMLCollection. In JavaScript, it is easier to treat the
HTMLCollection as an array and to index it using array notation. See the
example below.
Examples
const images = document.images; // This is an HTMLCollection
const img0 = images.item(0); // You can use the item() method this way
const img1 = images[1]; // But this notation is easier and more common
