* A complete keyboard events cross-browser compatibility layer.
*
* <p>Unfortunately, due to the important differences across Web browsers,
* simply using the available properties in a single keyboard event is not
* enough to accurately determine the key the user pressed. Thus, one needs to
* have event handlers for all keyboard-related events <code>keydown</code>,
* <code>keypress</code> and <code>keyup</code>.
*
* <p>This class provides a complete keyboard event compatibility layer. For any
* new instance you provide the DOM element you want to listen events for, and
* the event handlers for any of the three events <code>keydown</code>
* / <code>keypress</code> / <code>keyup</code>.
*
* <p>Your event handlers will receive the original DOM Event object, with
* several new properties defined:
*
* <ul>
* <li><var>event.keyCode_</var> holds the correct code for event key.
*
* <li><var>event.key_</var> holds the key the user pressed. It can be either
* a key name like "PageDown", "Delete", "Enter", or it is a character like
* "A", "1", or "[".
*
* <li><var>event.charCode_</var> holds the Unicode character decimal code.
*
* <li><var>event.char_</var> holds the character generated by the event.
*
* <li><var>event.repeat_</var> is a boolean property telling if the
* <code>keypress</code> event is repeated - the user is holding down the key
* for a long-enough period of time to generate multiple events.
* </ul>
*
* <p>The character-related properties, <var>charCode_</var> and
* <var>char_</var> are only available in the <code>keypress</code> and
* <code>keyup</code> event objects.
*
* <p>This class will ensure that the <code>keypress</code> event is always
* fired in Webkit and MSIE for all keys, except modifiers. For modifier keys
* like <kbd>Shift</kbd>, <kbd>Control</kbd>, and <kbd>Alt</kbd>, the
* <code>keypress</code> event will not be fired, even if the Web browser does
* it.
*
* <p>Some user agents like Webkit repeat the <code>keydown</code> event while
* the user holds down a key. This class will ensure that only the
* <code>keypress</code> event is repeated.
*
* <p>If you want to prevent the default action for an event, you should prevent
* it on <code>keypress</code>. This class will prevent the default action for
* <code>keydown</code> if need (in MSIE).
*
* @example
* <code>var <var>klogger</var> = function (<var>ev</var>) {
* console.log(<var>ev</var>.type +
* ' keyCode_ ' + <var>ev</var>.keyCode_ +
* ' key_ ' + <var>ev</var>.key_ +
* ' charCode_ ' + <var>ev</var>.charCode_ +
* ' char_ ' + <var>ev</var>.char_ +
* ' repeat_ ' + <var>ev</var>.repeat_);
* };
*
* var <var>kbListener</var> = new pwlib.dom.KeyboardEventListener(window,
* {keydown: <var>klogger</var>,
* keypress: <var>klogger</var>,
* keyup: <var>klogger</var>});</code>
*
* // later when you're done...
* <code><var>kbListener</var>.detach();</code>
*
* @class A complete keyboard events cross-browser compatibility layer.
*
* @param {Element} elem_ The DOM Element you want to listen events for.
*
* @param {Object} handlers_ The object holding the list of event handlers
* associated to the name of each keyboard event you want to listen. To listen
* for all the three keyboard events use <code>{keydown: <var>fn1</var>,
* keypress: <var>fn2</var>, keyup: <var>fn3</var>}</code>.
*
* @throws {TypeError} If the <var>handlers_</var> object does not contain any
* event handler.
*/
pwlib.dom.KeyboardEventListener = function (elem_, handlers_) {
/*
Technical details:
For the keyup and keydown events the keyCode provided is that of the virtual
key irrespective of other modifiers (e.g. Shift). Generally, during the
keypress event, the keyCode holds the Unicode value of the character
resulted from the key press, say an alphabetic upper/lower-case char,
depending on the actual intent of the user and depending on the currently
active keyboard layout.
Examples:
* Pressing p you get keyCode 80 in keyup/keydown, and keyCode 112 in
keypress. String.fromCharCode(80) = 'P' and String.fromCharCode(112) = 'p'.
* Pressing P you get keyCode 80 in all events.
* Pressing F1 you get keyCode 112 in keyup, keydown and keypress.
* Pressing 9 you get keyCode 57 in all events.
* Pressing Shift+9 you get keyCode 57 in keyup/keydown, and keyCode 40 in
keypress. String.fromCharCode(57) = '9' and String.fromCharCode(40) = '('.
* Using the Greek layout when you press v on an US keyboard you get the
output character ω. The keyup/keydown events hold keyCode 86 which is V.
This does make sense, since it's the virtual key code we are dealing with
- not the character code, not the result of pressing the key. The keypress
event will hold keyCode 969 (ω).
* Pressing NumPad_Minus you get keyCode 109 in keyup/keydown and keyCode 45
in keypress. Again, this happens because in keyup/keydown you don't get the
character code, you get the key code, as indicated above. For
your information: String.fromCharCode(109) = 'm' and String.fromCharCode(45)
= '-'.
Therefore, we need to map all the codes of several keys, like F1-F12,
Escape, Enter, Tab, etc. This map is held by pwlib.dom.keyCodes. It
associates, for example, code 112 to F1, or 13 to Enter. This map is used to
detect virtual keys in all events.
(This is only the general story, details about browser-specific differences
follow below.)
If the code given by the browser doesn't appear in keyCode maps, it's used
as is. The key_ returned is that of String.fromCharCode(keyCode).
In all browsers we consider all events having keyCode <= 32, as being events
generated by a virtual key (not a character). As such, the keyCode value is
always searched in pwlib.dom.keyCodes.
As you might notice from the above description, in the keypress event we
cannot tell the difference from say F1 and p, because both give the code
112. In Gecko and Webkit we can tell the difference because these UAs also
set the charCode event property when the key generates a character. If F1 is
pressed, or some other virtual key, charCode is never set.
In Opera the charCode property is never set. However, the 'which' event
property is not set for several virtual keys. This means we can tell the
difference between a character and a virtual key. However, there's a catch:
not *all* virtual keys have the 'which' property unset. Known exceptions:
Backspace (8), Tab (9), Enter (13), Shift (16), Control (17), Alt (18),
Pause (19), Escape (27), End (35), Home (36), Insert (45), Delete (46) and
NumLock (144). Given we already consider any keyCode <= 32 being one of some
virtual key, fewer exceptions remain. We only have the End, Home, Insert,
Delete and the NumLock keys which cannot be 100% properly detected in the
keypress event, in Opera. To properly detect End/Home we can check if the
Shift modifier is active or not. If the user wants # instead of End, then
Shift must be active. The same goes for $ and Home. Thus we now only have
the '-' (Insert) and the '.' (Delete) characters incorrectly detected as
being Insert/Delete.
The above brings us to one of the main visible difference, when comparing
the pwlib.dom.KeyboardEventListener class and the simple
pwlib.dom.KeyboardEvent.getKey() function. In getKey(), for the keypress
event we cannot accurately determine the exact key, because it requires
checking the keyCode used for the keydown event. The KeyboardEventListener
class monitors all the keyboard events, ensuring a more accurate key
detection.
Different keyboard layouts and international characters are generally
supported. Tested and known to work with the Cyrillic alphabet (Greek
keyboard layout) and with the US Dvorak keyboard layouts.
Opera does not fire the keyup event for international characters when
running on Linux. For example, this happens with the Greek keyboard layout,
when trying Cyrillic characters.
Gecko gives no keyCode/charCode/which for international characters when
running on Linux, in the keyup/keydown events. Thus, all such keys remain
unidentified for these two events. For the keypress event there are no
issues with such characters.
Webkit and Konqueror 4 also implement the keyIdentifier property from the
DOM 3 Events specification. In theory, this should be great, but it's not
without problems. Sometimes keyCode/charCode/which are all 0, but
keyIdentifier is properly set. For several virtual keys the keyIdentifier
value is simply 'U+0000'. Thus, the keyIdentifier is used only if the value
is not 'Unidentified' / 'U+0000', and only when keyCode/charCode/which are
not available.
Konqueror 4 does not use the 'U+XXXX' notation for Unicode characters. It
simply gives the character, directly.
Additionally, Konqueror seems to have some problems with several keyCodes in
keydown/keyup. For example, the key '[' gives keyCode 91 instead of 219.
Thus, it effectively gives the Unicode for the character, not the key code.
This issue is visible with other key as well.
NumPad_Clear is unidentified on Linux in all browsers, but it works on
Windows.
In MSIE the keypress event is only fired for characters and for Escape,
Space and Enter. Similarly, Webkit only fires the keypress event for
characters. However, Webkit does not fire keypress for Escape.
International characters and different keyboard layouts seem to work fine in
MSIE as well.
As of MSIE 4.0, the keypress event fires for the following keys:
* Letters: A - Z (uppercase and lowercase)
* Numerals: 0 - 9
* Symbols: ! @ # $ % ^ & * ( ) _ - + = < [ ] { } , . / ? \ | ' ` " ~
* System: Escape (27), Space (32), Enter (13)
Documentation about the keypress event:
http://msdn.microsoft.com/en-us/library/ms536939(VS.85).aspx
As of MSIE 4.0, the keydown event fires for the following keys:
* Editing: Delete (46), Insert (45)
* Function: F1 - F12

* Numerals: 0 - 9
* Symbols: ! @ # $ % ^ & * ( ) _ - + = < [ ] { } , . / ? \ | ' ` " ~
* System: Escape (27), Space (32), Shift (16), Tab (9)
As of MSIE 5, the event also fires for the following keys:

* Navigation: PageUp (33), PageDown (34)
* System: Shift+Tab (9)
Documentation about the keydown event:
http://msdn.microsoft.com/en-us/library/ms536938(VS.85).aspx
As of MSIE 4.0, the keyup event fires for the following keys:

* Symbols: ! @ # $ % ^ & * ( ) _ - + = < [ ] { } , . / ? \ | ' ` " ~
* System: Escape (27), Space (32), Shift (16), Tab (9)
As of MSIE 5, the event also fires for the following keys:

charCode is never set.
which is always set.
keyIdentifier is always undefined.
Gecko keypress:
This event fires for all keys, except for modifiers themselves.
keyCode is only set for virtual keys, not for characters.
charCode is always set for all characters.
which is always set for all characters and for the Enter virtual key.
keyIdentifier is always undefined.
Another important difference between the KeyboardEventListener class and the
getKey() function is that the class tries to ensure that the keypress event
is fired for the handler, even if the Web browser does not do it natively.
Also, the class tries to provide a consistent approach to keyboard event
repetition when the user holds down a key for longer periods of time, by
repeating only the keypress event.
On Linux, Opera, Firefox and Konqueror do not repeat the keydown event, only
keypress. On Windows, Opera, Firefox and MSIE do repeat the keydown and
keypress events while the user holds down the key. Webkit repeats the
keydown and the keypress (when it fires) events on both systems.
The default action can be prevented for during keydown in MSIE, and during
keypress for the other browsers. In Webkit when keypress doesn't fire,
keydown needs to be prevented.
The KeyboardEventListener class tries to bring consistency. The keydown
event never repeats, only the keypress event repeats and it always fires for
all keys. The keypress event never fires for modifiers. Events should always
be prevented during keypress - the class deals with preventing the event
during keydown or keypress as needed in Webkit and MSIE.
If no code/keyIdentifier is given by the browser, the getKey() function
returns null. In the case of the KeyboardEventListener class, keyCode_
/ key_ / charCode_ / char_ will be null or undefined.

http://www.JSON.org/json2.js

Public Domain.
NO WARRANTY EXPRESSED OR IMPLIED. USE AT YOUR OWN RISK.
See http://www.JSON.org/js.html
This file creates a global JSON object containing two methods: stringify
and parse.
JSON.stringify(value, replacer, space)
value any JavaScript value, usually an object or array.
replacer an optional parameter that determines how object
values are stringified for objects. It can be a
function or an array of strings.
space an optional parameter that specifies the indentation
of nested structures. If it is omitted, the text will
be packed without extra whitespace. If it is a number,
it will specify the number of spaces to indent at each
level. If it is a string (such as '\t' or ' '),
it contains the characters used to indent at each level.
This method produces a JSON text from a JavaScript value.
When an object value is found, if the object contains a toJSON
method, its toJSON method will be called and the result will be
stringified. A toJSON method does not serialize: it returns the
value represented by the name/value pair that should be serialized,
or undefined if nothing should be serialized. The toJSON method
will be passed the key associated with the value, and this will be
bound to the object holding the key.
For example, this would serialize Dates as ISO strings.
Date.prototype.toJSON = function (key) {
function f(n) {
// Format integers to have at least two digits.
return n < 10 ? '0' + n : n;
}
return this.getUTCFullYear() + '-' +
f(this.getUTCMonth() + 1) + '-' +
f(this.getUTCDate()) + 'T' +
f(this.getUTCHours()) + ':' +
f(this.getUTCMinutes()) + ':' +
f(this.getUTCSeconds()) + 'Z';
};
You can provide an optional replacer method. It will be passed the
key and value of each member, with this bound to the containing
object. The value that is returned from your method will be
serialized. If your method returns undefined, then the member will
be excluded from the serialization.
If the replacer parameter is an array of strings, then it will be
used to select the members to be serialized. It filters the results
such that only members with keys listed in the replacer array are
stringified.
Values that do not have JSON representations, such as undefined or
functions, will not be serialized. Such values in objects will be
dropped; in arrays they will be replaced with null. You can use
a replacer function to replace those with JSON values.
JSON.stringify(undefined) returns undefined.
The optional space parameter produces a stringification of the
value that is filled with line breaks and indentation to make it
easier to read.
If the space parameter is a non-empty string, then that string will
be used for indentation. If the space parameter is a number, then
the indentation will be that many spaces.
Example:
text = JSON.stringify(['e', {pluribus: 'unum'}]);
// text is '["e",{"pluribus":"unum"}]'
text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
// text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'
text = JSON.stringify([new Date()], function (key, value) {
return this[key] instanceof Date ?
'Date(' + this[key] + ')' : value;
});
// text is '["Date(---current time---)"]'
JSON.parse(text, reviver)
This method parses a JSON text to produce an object or array.
It can throw a SyntaxError exception.
The optional reviver parameter is a function that can filter and
transform the results. It receives each of the keys and values,
and its return value is used instead of the original value.
If it returns what it received, then the structure is not modified.
If it returns undefined then the member is deleted.
Example:
// Parse the text. Values that look like ISO date strings will
// be converted to Date objects.
myData = JSON.parse(text, function (key, value) {
var a;
if (typeof value === 'string') {
a =
/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
if (a) {
return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
+a[5], +a[6]));
}
}
return value;
});
myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) {
var d;
if (typeof value === 'string' &&
value.slice(0, 5) === 'Date(' &&
value.slice(-1) === ')') {
d = new Date(value.slice(5, -1));
if (d) {
return d;
}
}
return value;
