-----------------------------------------
|
|
|
|
An on-screen virtual keyboard embedded within the browser window which
|
|
will popup when a specified entry field is focused. The user can then
|
|
type and preview their input before Accepting or Canceling.
|
|
|
|
As a plugin to jQuery UI styling and theme will automatically
|
|
match that used by jQuery UI with the exception of the required
|
|
CSS listed below.
|
|
|
|
Requires:
|
|
jQuery
|
|
jQuery UI (position utility only) & CSS
|
|
|
|
Usage:
|
|
$('input[type=text], input[type=password], textarea')
|
|
.keyboard({
|
|
layout:"qwerty",
|
|
customLayout: {
|
|
'default': [
|
|
"q w e r t y {bksp}",
|
|
"s a m p l e {shift}",
|
|
"{accept} {space} {cancel}"
|
|
],
|
|
'shift' : [
|
|
"Q W E R T Y {bksp}",
|
|
"S A M P L E {shift}",
|
|
"{accept} {space} {cancel}"
|
|
]
|
|
}
|
|
});
|
|
|
|
Options:
|
|
layout
|
|
[String] specify which keyboard layout to use
|
|
qwerty - Standard QWERTY layout (Default)
|
|
international - US international layout
|
|
alpha - Alphabetical layout
|
|
dvorak - Dvorak Simplified layout
|
|
num - Numerical (ten-key) layout
|
|
custom - Uses a custom layout as defined by the customLayout option
|
|
|
|
customLayout
|
|
[Object] Specify a custom layout
|
|
An Object containing a set of key:value pairs, each key is a keyset.
|
|
The key can be one to four rows (default, shifted, alt and alt-shift) or any number of meta key sets (meta1, meta2, etc).
|
|
The value is an array with string elements of which each defines a new keyboard row.
|
|
Each string element must have each character or key seperated by a space.
|
|
To include an action key, select the desired one from the list below, or define your own by adding it to the $.keyboard.keyaction variable
|
|
In the list below where two special/"Action" keys are shown, both keys have the same action but different appearances (abbreviated/full name keys).
|
|
Special/"Action" keys include:
|
|
{a}, {accept} - Updates element value and closes keyboard
|
|
{alt},{altgr} - AltGr for International keyboard
|
|
{b}, {bksp} - Backspace
|
|
{c}, {cancel} - Clears changes and closes keyboard
|
|
{clear} - Clear input window - used in num pad
|
|
{combo} - Toggle combo (diacritic) key
|
|
{dec} - Decimal for numeric entry, only allows one decimal (optional use in num pad)
|
|
{default} - Switch to the default keyset
|
|
{e}, {enter} - Return/New Line
|
|
{empty} - empty (blank) key
|
|
{lock} - Caps lock key
|
|
{meta#} - Meta keys that change the key set (# can be any integer)
|
|
{next} - Switch to next keyboard input/textarea
|
|
{prev} - Switch to previous keyboard input/textarea
|
|
{s}, {shift} - Shift
|
|
{sign} - Change sign of numeric entry (positive or negative)
|
|
{sp:#} - Replace # with a numerical value, adds blank space, value of 1 ~ width of one key
|
|
{space} - Spacebar
|
|
{t}, {tab} - Tab
|
|
|
|
CSS:
|
|
Please see the keyboard.css file
