Properties

Password inherits properties from Input and HTMLElement and defines or overrides the following:

value

A read/write string that specifies the password entered by the user. It is the value sent over the Net when the form is submitted.

Methods

Event Handlers

                         // Specifies the name property
    [ value="default" ]  // The default value transmitted when the form is submitted
