The HTMLFormControlsCollection interface represents a collection of HTML form control elements, returned by the HTMLFormElement interface's elements property.
The collection returned by HTMLFormElement.elements includes the form's associated listed form controls. See HTMLFormElement.elements for the list of listed form controls and an explanation of form association.
This interface replaces one method from HTMLCollection, on which it is based.
This interface inherits the properties of its parent, HTMLCollection.
This interface inherits the methods of its parent, HTMLCollection.
HTMLFormControlsCollection.namedItem()Returns the RadioNodeList or the Element in the collection whose name or id matches the specified name, or null if no nodes match. Note that this version of namedItem() hides the one inherited from HTMLCollection. Like that method, using the JavaScript array bracket syntax with a String, as in collection["value"], is equivalent to collection.namedItem("value").
