HTMLCollection.item() gets an element by position.
Parameters
- index
- The position of the Node to be returned. Elements appear in an HTMLCollection in the same order in which they appear in the document source.
Return value
The Node at the specified index, or null if index is less than zero or greater than or equal to the length property.
Description
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.
Example
var c = document.images; // This is an HTMLCollection var img0 = c.item(0); // You can use the item( ) method this way var img1 = c[1]; // But this notation is easier and more common
