Gamepad.id - Web APIs 编辑

The Gamepad.id property of the Gamepad interface returns a string containing some information about the controller.

The exact syntax is not strictly specified, but in Firefox it will contain three pieces of information separated by dashes (-):

• Two 4-digit hexadecimal strings containing the USB vendor and product id of the controller
• The name of the controller as provided by the driver.

For example, a PS2 controller returned 810-3-USB Gamepad.

This information is intended to allow you to find a mapping for the controls on the device as well as display useful feedback to the user.
