HTMLFormControlsCollection.namedItem() - Web APIs 编辑

The HTMLFormControlsCollection.namedItem() method returns the RadioNodeList or the Element in the collection whose name or id match the specified name, or null if no node matches.

Note that this version of namedItem() hides the one inherited from HTMLCollection. Like that one, in JavaScript, using the array bracket syntax with a String, like collection["value"] is equivalent to collection.namedItem("value").

Syntax

var item = collection.namedItem(str);
var item = collection[str];

Parameters

• str is a DOMString

Return value

• item is a RadioNodeList , Element, or null.
