How do I get the value of a form control?

Correct answers include:

"Form controls can be referred to in different ways, depending on
the context of the reference and the location of the target control.

The following ways are fully standards-compliant (the proprietary `document'
property serves as a starting point for the implementation). Nevertheless,
you should perform run-time feature-tests prior to calling these methods as
not all browsers implement all standards.

1. Referring to a control that is not located within a form, is located
in the same form or in another form:

By ID: document.getElementById("...") [DOM3Core]
By name: document.getElementsByName("...")[...] [DOM2HTML]
By element type: document.getElementsByTagName("...")[...] [DOM3Core]
By XPath: document.evaluate("...")... [DOMXPath]

By CSS selector: document.querySelectorAll("...")[...] [Selector]
