The HTMLFormControlsCollection interface represents a collection of HTML form control elements. It replaces one method of HTMLCollection.

This interface is used by the HTMLFormElement interface's elements property, and the HTMLFieldSetElement interface's elements property.

Properties

This interface inherits the properties of its parent, HTMLCollection.

Methods

This interface inherits the methods of its parent, HTMLCollection.

HTMLFormControlsCollection.namedItem(): Returns the RadioNodeList or the Element in the collection whose name or id match the specified name, or null if no nodes match. Note that this version of namedItem() hide 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").
