View source for Internet Browser

<b>Internet Browser</b> is a web browser preloaded on the Wii U. It is based on NetFront Browser NX v2.1 (3.0 in later [[System Software]]), which uses the WebKit rendering engine.

As a mobile-style WebKit-based browser, most advice relevant to [http://developer.apple.com/library/ios/documentation/AppleApplications/Reference/SafariWebContent/Introduction/Introduction.html#//apple_ref/doc/uid/TP40002051-CH1-SW1 iOS Safari] web development applies to developing for Internet Browser as well.

== Homebrew using Internet Browser ==
* [https://github.com/corbindavenport/imageshare ImageShare]
* [[WiiuBru Go]]
* [[Indexiine]]

== Noteworthy Properties ==

The Internet Browser uses a native resolution of 854x448 pixels, matching the screen resolution of the Gamepad, accounting for the top address bar. With an active navigation bar, the visible area is reduced to 854x400 pixels. Unless otherwise specified via the ''viewport'' meta tag, the browser assumes a virtual width of 980 pixels.

The browser supports a single, yet unidentified sans-serif font. This font serves as the universal fallback, even for the default document font which is defined as "Times New Roman". Unicode range 0xE000–0xF8FF is used for private characters. The Wii U Internet Browser font as Nintendo related character up to 0xE09A. Characters from 0xE000 to 0xE06B are similar to the ones available on the Wii Internet Channel. Going to [[/font|this web page]] with your Wii U Gamepad will show you all these custom characters. Webfonts are supported.

== Multimedia Support ==

Internet Browser supports HTML5 audio and video but the <video> and <audio> tag are not implemented. The only video format supported is H.264 either in an MPEG-4 container or in an MPEG-2 transport stream with a M3U8 index according to the HTTP Live Streaming specification. The only audio format supported is AAC encoded with the Low Complexity (LC) profile in an MPEG-4 container. 

The browser can display BMP, PNG, GIF, JPEG, and SVG images, but Image Preview mode only supports JPEG images.

Other HTML5 features supported include canvas, web storage, web messaging, server-sent events, device orientation, and WOFF.

External plugins, such as Flash and Java, are not supported.

== Controls ==
Under normal circumstances, Internet Browser uses the following controls:

== Wii U Scripting Functionality ==
In addition to W3C standard keyboard, touch screen, and motion tracking functionality, Internet Browser exposes many Wii U input and output functions to Javascript through the <tt>wiiu</tt> object.

=== W3C Events ===

Internet Browser supports the following W3C input events:

{| class='wikitable'
! Event Name
! Callback Function
! W3C Documentation
|-
| <tt>"keydown"</tt>
| <i>element</i><tt>.onkeydown</tt>
| rowspan="9" | [http://www.w3.org/TR/DOM-Level-3-Events/#events-keyboardevents DOM Level 3]
|-
| <tt>"keypress"</tt>

| rowspan="2" | [http://www.w3.org/TR/orientation-event/ DeviceOrientation Event Specification]
|-
| <tt>"deviceorientation"</tt>
| <tt>window.ondeviceorientation</tt>
|}
<sup>[1]</sup> The mouseover, mouseout, and mousemove events only work for clickable elements, i.e., elements with a defined <tt>onclick</tt> handler.

Only the following buttons are recognized with the key events:

{| class='wikitable'
! Button
! keyCode
|-
| {{WiiUGamePadAButton}}
| 13
|-
| {{WiiUGamePadDPadLeft}}
| 37
|-
| {{WiiUGamePadDPadUp}}
| 38
|-
| {{WiiUGamePadDPadRight}}
| 39
|-
| {{WiiUGamePadDPadDown}}
| 40
|}

Additionally, most non-input events from [http://www.w3.org/TR/DOM-Level-3-Events/#events-keyboardevents DOM Level 3] are supported.

=== Supported HTML5 Features ===

* [http://www.w3.org/TR/SVG/ SVG]
* Canvas [http://www.w3.org/TR/2dcontext/ 2D Context]
* [http://dev.w3.org/html5/spec/history.html Session History]

Note that local storage is cleared when the browser is closed. Web messaging may not be fully functional. (<b>TODO:</b> <i>test this</i>)

=== wiiu.gamepad ===
The <tt>wiiu.gamepad</tt> object allows Javascript functions to read the current state of the primary GamePad.

==== Reading values ====
In order to read any values from the GamePad, the function <tt>wiiu.gamepad.update()</tt> must be invoked. This will populate all of the properties on the <tt>wiiu.gamepad</tt> object with the current information about the sticks, accelerometers, gyroscopes, buttons, and touch screen. For convenience, this function also returns a reference to the <tt>wiiu.gamepad</tt> object, allowing for idioms like <tt>var state = wiiu.gamepad.update();</tt>. It is safe to invoke this function in a timer for real-time updates.

After a successful update, <tt>wiiu.gamepad.isDataValid</tt> will be set to 1. If no update has happened yet, or if the GamePad is not connected, it will be set to 0.

If the GamePad is connected wiiu.gamepad.isEnabled will be set to 1, else it will be set to 0.

==== Touch Screen ====
The <tt>wiiu.gamepad.tpTouch</tt> variable indicates whether or not there is currently an active touch on the screen. If this variable is 1, the following variables will be set:
{| class='wikitable'
! Variable
! Value
|-
|<tt>wiiu.gamepad.tpTouch</tt>
|1 if touch is present
|-
|<tt>wiiu.gamepad.tpValidity</tt>
|0 = X and Y coordinates valid
1 = X coordinate invalid
2 = Y coordinate invalid
3 = X and Y coordinates invalid
|-
|<tt>wiiu.gamepad.tpX</tt>
|X position in screen coordinates
|-
|<tt>wiiu.gamepad.tpY</tt>
|Y position in screen coordinates
|-
|<tt>wiiu.gamepad.contentX</tt>
|X position in page coordinates
|-
|<tt>wiiu.gamepad.contentY</tt>
|Y position in page coordinates
|}

==== Analog Sticks ====
The following variables store the current state of the left and right analog sticks. Each value ranges from -1.0 to +1.0.
{| class='wikitable'
! Variable
! Value
|-
|<tt>wiiu.gamepad.lStickX
|{{WiiUGamePadLControlStick}} X deflection
|-
|<tt>wiiu.gamepad.lStickY
|{{WiiUGamePadLControlStick}} Y deflection
|-
|<tt>wiiu.gamepad.rStickX
|{{WiiUGamePadRControlStick}} X deflection
|-
|<tt>wiiu.gamepad.rStickY
|{{WiiUGamePadRControlStick}} Y deflection
|}

==== Buttons ====
The variable <tt>wiiu.gamepad.hold</tt> is a bitmask indicating all buttons currently being depressed on the GamePad, including the click states of the analog sticks. Almost all buttons are represented by in this bitmask although the browser's default behaviors may cause some values to be unusable.

The Power button does not appear in the <tt>hold</tt> variable in the browser, probably 0x01. 

Pressing the Home button closes the browser but triggers the event with keycode 2, So you can see that by going back to the browser after pressing it (The Power button doesn't trigger the event).

==== Accelerometer ====
The following variables hold the current state of the GamePad's accelerometers.
{| class='wikitable'
! Variable
! Value
|-
| <tt>wiiu.gamepad.accX</tt>
| Force on X (horizontal) axis
|-
| <tt>wiiu.gamepad.accY</tt>
| Force on Y (depth) axis
|-
| <tt>wiiu.gamepad.accZ</tt>
| Force on Z (vertical) axis
|}

These variables form a vector showing the current acceleration forces on the GamePad, measured in Gs. When held level and motionless, the force of gravity will cause these variables to contain the vector (0.0, -1.0, 0.0).

==== Gyroscope ====
The following variables hold the current state of the GamePad's gyroscopes.
{| class='wikitable'
! Variable
! Value
|-
| <tt>wiiu.gamepad.gyroX</tt>
| Rotation speed around X (horizontal) axis
|-
| <tt>wiiu.gamepad.gyroY</tt>
| Rotation speed around Y (depth) axis
|-
| <tt>wiiu.gamepad.gyroZ</tt>
| Rotation speed around Z (vertical) axis
|}

When the GamePad is motionless these values hover around 0.0.

==== Angle ====
The following variables hold the current angle of rotation of the GamePad.
{| class='wikitable'
! Variable
! Value
|-
| <tt>wiiu.gamepad.angleX</tt>
| Rotation around X (horizontal) axis
|-
| <tt>wiiu.gamepad.angleY</tt>
| Rotation around Y (depth) axis
|-
| <tt>wiiu.gamepad.angleZ</tt>
| Rotation around Z (vertical) axis
|}

A change of 1.0 in these values represents a complete revolution around the specified axis. These variables do not appear to wrap around; multiple revolutions around the same axis will cause the value to continuously increase or decrease.

If properly calibrated, angleX and angleZ should hover around 0.0 when the GamePad is held level, but as the gyroscopes have limited range and resolution the alignment will drift with use.

==== Orientation ====
There are nine variables that tie into the GamePad's orientation tracking, organized into three three-dimensional vectors:

{| class='wikitable'
! Axis
! X
! Y
! Z
|-
| X (horizontal) axis
| <tt>wiiu.gamepad.dirXx</tt>
| <tt>wiiu.gamepad.dirXy</tt>
| <tt>wiiu.gamepad.dirXz</tt>
|-
| Y (depth) axis
| <tt>wiiu.gamepad.dirYx</tt>
| <tt>wiiu.gamepad.dirYy</tt>
| <tt>wiiu.gamepad.dirYz</tt>
|-
| Z (vertical) axis
| <tt>wiiu.gamepad.dirZx</tt>
| <tt>wiiu.gamepad.dirZy</tt>
| <tt>wiiu.gamepad.dirZz</tt>
|}

This is a basis of three perpendicular unit vectors; that is, each vector has length 1.0 and points along the relevant axis of the GamePad relative to an arbitrary starting orientation in three-dimensional space.

=== wiiu.remote ===
While Internet Browser exposes a <tt>wiiu.remote</tt> object, at the present time no way is known how to activate it. Presumedly it would allow Javascript functions to read the current state of the primary Wii Remote and its Motion Plus accessory.

All subsequent documentation is only a best guess at functionality based on the property names and how it worked on the Wii.

==== Reading values ====
In order to read any values from a Wii Remote, the function <tt>wiiu.remote.update(n)</tt> must be invoked, where <tt>n</tt> is the number of the Wii Remote. This populates all of the properties on the <tt>wiiu.remote</tt> object with the current information about the pointer, accelerometers, gyroscopes, and buttons of the selected Wii Remote. For convenience, this function also returns a reference to the <tt>wiiu.remote</tt> object, allowing for idioms like <tt>var state = wiiu.remote.update(0);</tt>. It is safe to invoke this function in a timer for real-time updates.

If the specified Wii Remote returns valid data, <tt>wiiu.remote.isDataValid</tt> will be set to 1. If no update has happened yet, or if the selected Wii Remote is not connected, it will be set to 0.

==== Buttons ====
The variable <tt>wiiu.remote.held</tt> is a bitmask indicating all buttons currently being depressed on the Wii Remote.

==== Accelerometer ====
The following variables hold the current state of the Wii Remote's accelerometers.
{| class='wikitable'
! Variable
! Value
|-
| <tt>wiiu.remote.accX</tt>
| Force on X (horizontal) axis
|-
| <tt>wiiu.remote.accY</tt>
| Force on Y (depth) axis
|-
| <tt>wiiu.remote.accZ</tt>
| Force on Z (vertical) axis
|}

These variables form a vector showing the current acceleration forces on the Wii Remote, measured in Gs. When held level and motionless, the force of gravity will cause these variables to contain the vector (0.0, -1.0, 0.0).

==== Pointer ====
The following variables track the Wii Remote's cursor on the screen.
{| class='wikitable'
! Variable
! Value
|-
| <tt>wiiu.remote.dpdX</tt>
| X position in screen coordinates
|-
| <tt>wiiu.remote.dpdY</tt>
| Y position in screen coordinates
|-
| <tt>wiiu.remote.dpdDistance</tt>
| Distance between Wii Remote and Sensor Bar
|-
| <tt>wiiu.remote.contentX</tt>
| X position in page coordinates
|-
| <tt>wiiu.remote.contentY</tt>
| Y position in page coordinates
|-
| <tt>wiiu.remote.isCursorViewable</tt>
| 1 if cursor display is enabled
|-
| <tt>wiiu.remote.dpdValidity</tt>
| 0 = X and Y coordinates valid
1 = X coordinate invalid
2 = Y coordinate invalid
3 = X and Y coordinates invalid
|}

Additionally, the function <tt>wiiu.remote.setCursorViewable(n, enable)</tt> will enable or disable the display of a Wii Remote's cursor.

==== Motion Plus ====
There are nine variables that tie into the Motion Plus orientation tracking, organized into three three-dimensional vectors:

{| class='wikitable'
! Axis
! X
! Y
! Z
|-
| X (horizontal) axis
| <tt>wiiu.remote.mplsDirXx</tt>
| <tt>wiiu.remote.mplsDirXy</tt>
| <tt>wiiu.remote.mplsDirXz</tt>
|-
| Y (depth) axis
| <tt>wiiu.remote.mplsDirYx</tt>
| <tt>wiiu.remote.mplsDirYy</tt>
| <tt>wiiu.remote.mplsDirYz</tt>
|-
| Z (vertical) axis
| <tt>wiiu.remote.mplsDirZx</tt>
| <tt>wiiu.remote.mplsDirZy</tt>
| <tt>wiiu.remote.mplsDirZz</tt>
|}

This is a basis of three perpendicular unit vectors; that is, each vector has length 1.0 and points along the relevant axis of the GamePad relative to an arbitrary starting orientation in three-dimensional space.

The following variables are also available to track the motion of the Wii Remote:

{| class='wikitable'
