Internet Browser - Extended Functionality

With the Wii U Internet Browser, by using specialized JavaScript, it is possible to obtain button states of the GamePad or control how video and images (JPEG) are displayed.

• Sample page: To obtain values from the Wii U GamePad (Wii U Internet Browser required).
• Note: Nintendo provides this information as a courtesy and does not offer support on this extension function.

Developer Mode

This feature is available for Wii U System version 4.0.0U and above.

Change user agent:

Changes can be made from the Wii U console's Internet Browser > Start Page > Settings.

Enable developer tools:

1. Enable from the Wii U console's Internet Browser > Start Page > Settings.
2. Once enabled, you can use a browser on a PC on the same local network to inspect the code of any web page.
3. The developer tools work with Chrome [ver. 30.0.1599.101m] and Safari [ver. 6.0.3] and above.

Note: Changing the user agent and enabling developer tools will be disabled once the Wii U console's Internet Browser is closed.

Enhanced Video Playback Function

Embedded play (inline) on a webpage:

The Wii U console's Internet Browser generally plays video full screen. However, if text, pictures, or other elements need to be included with the video while it plays, embedding an inline video player can be done using the methods below:

• Insert webkit-playsinline into the video tag.
  • Example: <video webkit-playsinline controls>
• While holding down on a video tag, the option "Play video on web page" from the menu will be displayed. This button is only enabled when a video tag is found.
• Note: Since September 30, 2013, embedded inline video play can only be done on updated systems.

Suppression of autoplay:

Since the Wii U console's Internet Browser is unable to play 2 or more videos simultaneously, autoplay is suppressed under these conditions:

1. Video tag autoplay elements.
2. play() ordered by non-user operations (JavaScript timers, etc.).

Navigation & Focus

Using +Control Pad buttons to focus

• Focus movement rule: Focus moves to the first element found (anchor element link, tab index, etc.) when moving in the direction of the +Control Pad button pressed. If no element is found, the page scrolls for a determined quantity.
• Control method: You can call up a preventDefault method for the target element node's keydown event, or hide focus by returning false.
