Returns an element or a collection of elements from the current collection by name or index.
Parameters:
nameOrIndex
Required. A string or a zero-based integer that specifies the element or elements to retrieve.
If an integer value is specified, it specifies the index of the element to retrieve.
If this parameter is a string, then it specifies a value for the name or id property of the element or elements to retrieve.
Return value:
If no match is found, it returns undefined.
If exactly one match is found, it returns the matching form element.
If more than one match is found, it returns a forms sub-collection filled with the matching elements.
The sub-collection contains the matching elements in source order.
In Firefox, if more than one match is found, the first matching element is returned.
