Format Description Example returned values
------ ----------------------------------------------------------------------- -----------------------
d Day of the month, 2 digits with leading zeros 01 to 31
D A short textual representation of the day of the week Mon to Sun
j Day of the month without leading zeros 1 to 31
l A full textual representation of the day of the week Sunday to Saturday
N ISO-8601 numeric representation of the day of the week 1 (for Monday) through 7 (for Sunday)
S English ordinal suffix for the day of the month, 2 characters st, nd, rd or th. Works well with j
w Numeric representation of the day of the week 0 (for Sunday) to 6 (for Saturday)
z The day of the year (starting from 0) 0 to 364 (365 in leap years)
W ISO-8601 week number of year, weeks starting on Monday 01 to 53
F A full textual representation of a month, such as January or March January to December

M A short textual representation of a month Jan to Dec
n Numeric representation of a month, without leading zeros 1 to 12
t Number of days in the given month 28 to 31
L Whether it's a leap year 1 if it is a leap year, 0 otherwise.
o ISO-8601 year number (identical to (Y), but if the ISO week number (W) Examples: 1998 or 2004
belongs to the previous or next year, that year is used instead)
Y A full numeric representation of a year, 4 digits Examples: 1999 or 2003
y A two digit representation of a year Examples: 99 or 03
a Lowercase Ante meridiem and Post meridiem am or pm
A Uppercase Ante meridiem and Post meridiem AM or PM
g 12-hour format of an hour without leading zeros 1 to 12
G 24-hour format of an hour without leading zeros 0 to 23
h 12-hour format of an hour with leading zeros 01 to 12
H 24-hour format of an hour with leading zeros 00 to 23
i Minutes, with leading zeros 00 to 59
s Seconds, with leading zeros 00 to 59
u Decimal fraction of a second Examples:
(minimum 1 digit, arbitrary number of digits allowed) 001 (i.e. 0.001s) or
100 (i.e. 0.100s) or
999 (i.e. 0.999s) or
999876543210 (i.e. 0.999876543210s)
O Difference to Greenwich time (GMT) in hours and minutes Example: +1030
P Difference to Greenwich time (GMT) with colon between hours and minutes Example: -08:00
T Timezone abbreviation of the machine running the code Examples: EST, MDT, PDT ...
Z Timezone offset in seconds (negative if west of UTC, positive if east) -43200 to 50400
c ISO 8601 date
Notes: Examples:
1) If unspecified, the month / day defaults to the current month / day, 1991 or
the time defaults to midnight, while the timezone defaults to the 1992-10 or
browser's timezone. If a time is specified, it must include both hours 1993-09-20 or
and minutes. The "T" delimiter, seconds, milliseconds and timezone 1994-08-19T16:20+01:00 or
are optional. 1995-07-18T17:21:28-02:00 or
2) The decimal fraction of a second, if specified, must contain at 1996-06-17T18:22:29.98765+03:00 or
least 1 digit (there is no limit to the maximum number 1997-05-16T19:23:30,12345-0400 or
of digits allowed), and may be delimited by either a '.' or a ',' 1998-04-15T20:24:31.2468Z or
Refer to the examples on the right for the various levels of 1999-03-14T20:24:32Z or

U Seconds since the Unix Epoch (January 1 1970 00:00:00 GMT) 1193432466 or -2138434463
MS Microsoft AJAX serialized dates \/Date(1238606590509)\/ (i.e. UTC milliseconds since epoch) or
\/Date(1238606590509+0800)\/
*
* Example usage (note that you must escape format specifiers with '\\' to render them as character literals):
*
// Sample date:
// 'Wed Jan 10 2007 15:05:01 GMT-0600 (Central Standard Time)'
var dt = new Date('1/10/2007 03:05:01 PM GMT-0600');
console.log(Ext.Date.format(dt, 'Y-m-d')); // 2007-01-10
console.log(Ext.Date.format(dt, 'F j, Y, g:i a')); // January 10, 2007, 3:05 pm
console.log(Ext.Date.format(dt, 'l, \\t\\he jS \\of F Y h:i:s A')); // Wednesday, the 10th of January 2007 03:05:01 PM
*

* that would call the overridden method containing the bug. In other words, the
* above patch would only produce "Fixed" then "Good" in the console log, whereas,
* using `callParent` would produce "Fixed" then "Bad" then "Good".

/**
* @method
* Defines a class or override. A basic class is defined like this:
*
* Ext.define('My.awesome.Class', {
* someProperty: 'something',
*
* someMethod: function(s) {
* alert(s + this.someProperty);
* }
*
* ...
* });
*
* var obj = new My.awesome.Class();
*
* obj.someMethod('Say '); // alerts 'Say something'
*
* To create an anonymous class, pass `null` for the `className`:
*
* Ext.define(null, {
* constructor: function () {
* // ...
* }
* });
*
* In some cases, it is helpful to create a nested scope to contain some private
* properties. The best way to do this is to pass a function instead of an object
* as the second parameter. This function will be called to produce the class
* body:
*
* Ext.define('MyApp.foo.Bar', function () {
* var id = 0;
*
* return {
* nextId: function () {
* return ++id;
* }
* };
* });
*
* When using this form of `Ext.define`, the function is passed a reference to its
* class. This can be used as an efficient way to access any static properties you
* may have:
*
* Ext.define('MyApp.foo.Bar', function (Bar) {
* return {
* statics: {
* staticMethod: function () {
* // ...
* }
* },
*
* method: function () {
* return Bar.staticMethod();
* }
* };
* });
*
* To define an override, include the `override` property. The content of an
* override is aggregated with the specified class in order to extend or modify
* that class. This can be as simple as setting default property values or it can
* extend and/or replace methods. This can also extend the statics of the class.
*
* One use for an override is to break a large class into manageable pieces.
*
* // File: /src/app/Panel.js
*
* Ext.define('My.app.Panel', {
* extend: 'Ext.panel.Panel',
* requires: [
* 'My.app.PanelPart2',
* 'My.app.PanelPart3'
* ]
*
* constructor: function (config) {
* this.callParent(arguments); // calls Ext.panel.Panel's constructor
* //...
* },
*
* statics: {
* method: function () {
* return 'abc';
* }
* }
* });
*
* // File: /src/app/PanelPart2.js
* Ext.define('My.app.PanelPart2', {
* override: 'My.app.Panel',
*
* constructor: function (config) {
* this.callParent(arguments); // calls My.app.Panel's constructor
* //...
* }
* });
*
* Another use of overrides is to provide optional parts of classes that can be
* independently required. In this case, the class may even be unaware of the
* override altogether.
*
* Ext.define('My.ux.CoolTip', {
* override: 'Ext.tip.ToolTip',
*
* constructor: function (config) {
* this.callParent(arguments); // calls Ext.tip.ToolTip's constructor
* //...
* }
* });
*
* The above override can now be required as normal.
*
* Ext.define('My.app.App', {
* requires: [
* 'My.ux.CoolTip'
* ]
* });
*
* Overrides can also contain statics:
*
* Ext.define('My.app.BarMod', {
* override: 'Ext.foo.Bar',
*
* statics: {
* method: function (x) {
* return this.callParent([x * 2]); // call Ext.foo.Bar.method
* }
* }
* });
*
* IMPORTANT: An override is only included in a build if the class it overrides is
* required. Otherwise, the override, like the target class, is not included.
*
* @param {String} className The class name to create in string dot-namespaced format, for example:
* 'My.very.awesome.Class', 'FeedViewer.plugin.CoolPager'
* It is highly recommended to follow this simple convention:
* - The root and the class name are 'CamelCased'
* - Everything else is lower-cased
* Pass `null` to create an anonymous class.
* @param {Object} data The key - value pairs of properties to apply to this class. Property names can be of any valid
* strings, except those in the reserved listed below:
* - `mixins`
* - `statics`
* - `config`
* - `alias`
* - `self`
* - `singleton`
* - `alternateClassName`
* - `override`
*
* @param {Function} createdFn Optional callback to execute after the class is created, the execution scope of which
* (`this`) will be the newly created class itself.

* @class Ext.Loader
*
* Ext.Loader is the heart of the new dynamic dependency loading capability in Ext JS 4+. It is most commonly used
* via the {@link Ext#require} shorthand. Ext.Loader supports both asynchronous and synchronous loading
* approaches, and leverage their advantages for the best development flow. We'll discuss about the pros and cons of each approach:
*
* # Asynchronous Loading #
*
* - Advantages:
* + Cross-domain
* + No web server needed: you can run the application via the file system protocol (i.e: `file://path/to/your/index
* .html`)
* + Best possible debugging experience: error messages come with the exact file name and line number
*
* - Disadvantages:
* + Dependencies need to be specified before-hand
*
* ### Method 1: Explicitly include what you need: ###
*
* // Syntax
* Ext.require({String/Array} expressions);
*
* // Example: Single alias
* Ext.require('widget.window');
*
* // Example: Single class name
* Ext.require('Ext.window.Window');
*
* // Example: Multiple aliases / class names mix
* Ext.require(['widget.window', 'layout.border', 'Ext.data.Connection']);
*
* // Wildcards
* Ext.require(['widget.*', 'layout.*', 'Ext.data.*']);
*
* ### Method 2: Explicitly exclude what you don't need: ###
*
* // Syntax: Note that it must be in this chaining format.
* Ext.exclude({String/Array} expressions)
* .require({String/Array} expressions);
*
* // Include everything except Ext.data.*
* Ext.exclude('Ext.data.*').require('*');
*
* // Include all widgets except widget.checkbox*,
* // which will match widget.checkbox, widget.checkboxfield, widget.checkboxgroup, etc.
* Ext.exclude('widget.checkbox*').require('widget.*');
*
* # Synchronous Loading on Demand #
*
* - Advantages:
* + There's no need to specify dependencies before-hand, which is always the convenience of including ext-all.js
* before
*
* - Disadvantages:
* + Not as good debugging experience since file name won't be shown (except in Firebug at the moment)
* + Must be from the same domain due to XHR restriction
* + Need a web server, same reason as above
*
* There's one simple rule to follow: Instantiate everything with Ext.create instead of the `new` keyword
*
* Ext.create('widget.window', { ... }); // Instead of new Ext.window.Window({...});
*
* Ext.create('Ext.window.Window', {}); // Same as above, using full class name instead of alias
*
* Ext.widget('window', {}); // Same as above, all you need is the traditional `xtype`
*
* Behind the scene, {@link Ext.ClassManager} will automatically check whether the given class name / alias has already
* existed on the page. If it's not, Ext.Loader will immediately switch itself to synchronous mode and automatic load the given
* class and all its dependencies.
*
* # Hybrid Loading - The Best of Both Worlds #
*
* It has all the advantages combined from asynchronous and synchronous loading. The development flow is simple:
*
* ### Step 1: Start writing your application using synchronous approach.
*
* Ext.Loader will automatically fetch all dependencies on demand as they're needed during run-time. For example:
*
* Ext.onReady(function(){
* var window = Ext.widget('window', {
* width: 500,
* height: 300,
* layout: {
* type: 'border',
* padding: 5
* },
* title: 'Hello Dialog',
* items: [{
* title: 'Navigation',
* collapsible: true,
* region: 'west',
* width: 200,
* html: 'Hello',
* split: true
* }, {
* title: 'TabPanel',
* region: 'center'
* }]
* });
*
* window.show();
* })
*
* ### Step 2: Along the way, when you need better debugging ability, watch the console for warnings like these: ###
*
* [Ext.Loader] Synchronously loading 'Ext.window.Window'; consider adding Ext.require('Ext.window.Window') before your application's code
* ClassManager.js:432
* [Ext.Loader] Synchronously loading 'Ext.layout.container.Border'; consider adding Ext.require('Ext.layout.container.Border') before your application's code
*
* Simply copy and paste the suggested code above `Ext.onReady`, i.e:
*
* Ext.require('Ext.window.Window');
* Ext.require('Ext.layout.container.Border');
*
* Ext.onReady(...);
*
* Everything should now load via asynchronous mode.
*
* # Deployment #
*
* It's important to note that dynamic loading should only be used during development on your local machines.
* During production, all dependencies should be combined into one single JavaScript file. Ext.Loader makes
* the whole process of transitioning from / to between development / maintenance and production as easy as
* possible. Internally {@link Ext.Loader#history Ext.Loader.history} maintains the list of all dependencies your application
* needs in the exact loading sequence. It's as simple as concatenating all files in this array into one,
* then include it on top of your application.
*
* This process will be automated with Sencha Command, to be released and documented towards Ext JS 4 Final.

* @author Brian Moeskau
* @docauthor Brian Moeskau
*
* A wrapper class for the native JavaScript Error object that adds a few useful capabilities for handling
* errors in an Ext application. When you use Ext.Error to {@link #raise} an error from within any class that
* uses the Ext 4 class system, the Error class can automatically add the source class and method from which
* the error was raised. It also includes logic to automatically log the eroor to the console, if available,
* with additional metadata about the error. In all cases, the error will always be thrown at the end so that
* execution will halt.
*
* Ext.Error also offers a global error {@link #handle handling} method that can be overridden in order to
* handle application-wide errors in a single spot. You can optionally {@link #ignore} errors altogether,
* although in a real application it's usually a better idea to override the handling function and perform
* logging or some other method of reporting the errors in a way that is meaningful to the application.
*
* At its simplest you can simply raise an error as a simple string from within any code:
*
* Example usage:
*
* Ext.Error.raise('Something bad happened!');
*
* If raised from plain JavaScript code, the error will be logged to the console (if available) and the message
* displayed. In most cases however you'll be raising errors from within a class, and it may often be useful to add
* additional metadata about the error being raised. The {@link #raise} method can also take a config object.
* In this form the `msg` attribute becomes the error description, and any other data added to the config gets
* added to the error object and, if the console is available, logged to the console for inspection.
*
* Example usage:
*
* Ext.define('Ext.Foo', {
* doSomething: function(option){
* if (someCondition === false) {
* Ext.Error.raise({
* msg: 'You cannot do that!',
* option: option, // whatever was passed into the method
* 'error code': 100 // other arbitrary info
* });
* }
* }
* });
*
* If a console is available (that supports the `console.dir` function) you'll see console output like:
*
* An error was raised with the following data:
* option: Object { foo: "bar"}
* foo: "bar"
* error code: 100
* msg: "You cannot do that!"
* sourceClass: "Ext.Foo"
* sourceMethod: "doSomething"
*
* uncaught exception: You cannot do that!
*
* As you can see, the error will report exactly where it was raised and will include as much information as the
* raising code can usefully provide.
*
* If you want to handle all application errors globally you can simply override the static {@link #handle} method
* and provide whatever handling logic you need. If the method returns true then the error is considered handled
* and will not be thrown to the browser. If anything but true is returned then the error will be thrown normally.
*
* Example usage:
*
* Ext.Error.handle = function(err) {
* if (err.someProperty == 'NotReallyAnError') {
* // maybe log something to the application here if applicable
* return true;
* }
* // any non-true return value (including none) will cause the error to be thrown
* }
*

* @class Ext.util.Format
*
* This class is a centralized place for formatting functions. It includes
* functions to format various different types of data, such as text, dates and numeric values.
*
* ## Localization
*
* This class contains several options for localization. These can be set once the library has loaded,
* all calls to the functions from that point will use the locale settings that were specified.
*
* Options include:
*
* - thousandSeparator
* - decimalSeparator
* - currenyPrecision
* - currencySign
* - currencyAtEnd
*
* This class also uses the default date format defined here: {@link Ext.Date#defaultFormat}.
*
* ## Using with renderers
*
* There are two helper functions that return a new function that can be used in conjunction with
* grid renderers:
*
* columns: [{
* dataIndex: 'date',
* renderer: Ext.util.Format.dateRenderer('Y-m-d')
* }, {
* dataIndex: 'time',
* renderer: Ext.util.Format.numberRenderer('0.000')
* }]
*
* Functions that only take a single argument can also be passed directly:
*
* columns: [{
* dataIndex: 'cost',
* renderer: Ext.util.Format.usMoney
* }, {
* dataIndex: 'productCode',
* renderer: Ext.util.Format.uppercase
* }]
*
* ## Using with XTemplates
*
* XTemplates can also directly use Ext.util.Format functions:
*
* new Ext.XTemplate([
* 'Date: {startDate:date("Y-m-d")}',
* 'Cost: {cost:usMoney}'
* ]);
*

* - `0,0.00` - (123,456.78) shortcut method, show comma and digits, 2 precision

/**
* Provides the ability to execute one or more arbitrary tasks in a asynchronous manner.
* Generally, you can use the singleton {@link Ext.TaskManager} instead, but if needed,
* you can create separate instances of TaskRunner. Any number of separate tasks can be
* started at any time and will run independently of each other.
*
* Example usage:
*
* // Start a simple clock task that updates a div once per second
* var updateClock = function () {
* Ext.fly('clock').update(new Date().format('g:i:s A'));
* }
*
* var runner = new Ext.util.TaskRunner();
* var task = runner.start({
* run: updateClock,
* interval: 1000
* }
*
* The equivalent using TaskManager:
*
* var task = Ext.TaskManager.start({
* run: updateClock,
* interval: 1000
* });
*
* To end a running task:
*
* Ext.TaskManager.stop(task);
*
* If a task needs to be started and stopped repeated over time, you can create a
* {@link Ext.util.TaskRunner.Task Task} instance.
*
* var task = runner.newTask({
* run: function () {
* // useful code
* },
* interval: 1000
* });
*
* task.start();
*
* // ...
*
* task.stop();
*
* // ...
*
* task.start();
*
* A re-usable, one-shot task can be managed similar to the above:
*
* var task = runner.newTask({
* run: function () {
* // useful code to run once
* },
* repeat: 1
* });
*
* task.start();
*
* // ...
*
* task.start();
*
* See the {@link #start} method for details about how to configure a task object.
*
* Also see {@link Ext.util.DelayedTask}.
*

* @class Ext.util.DelayedTask
*
* The DelayedTask class provides a convenient way to "buffer" the execution of a method,
* performing setTimeout where a new timeout cancels the old timeout. When called, the
* task will wait the specified time period before executing. If durng that time period,
* the task is called again, the original call will be cancelled. This continues so that
* the function is only called a single time for each iteration.
*
* This method is especially useful for things like detecting whether a user has finished
* typing in a text field. An example would be performing validation on a keypress. You can
* use this class to buffer the keypress events for a certain number of milliseconds, and
* perform only if they stop for that amount of time.
*
* ## Usage
*
* var task = new Ext.util.DelayedTask(function(){
* alert(Ext.getDom('myInputField').value.length);
* });
*
* // Wait 500ms before calling our function. If the user presses another key
* // during that 500ms, it will be cancelled and we'll wait another 500ms.
* Ext.get('myInputField').on('keypress', function(){
* task.{@link #delay}(500);
* });
*
* Note that we are using a DelayedTask here to illustrate a point. The configuration
* option `buffer` for {@link Ext.util.Observable#addListener addListener/on} will
* also setup a delayed task for you to buffer events.
*
* @constructor The parameters to this constructor serve as defaults and are not required.
* @param {Function} fn (optional) The default function to call. If not specified here, it must be specified during the {@link #delay} call.
* @param {Object} scope (optional) The default scope (The this reference) in which the
* function is called. If not specified, this will refer to the browser window.

* there are no listeners. This can be particularly helpful when one would otherwise

* });
*

* the specified `scope`. Will be called with arguments
* given to {@link #fireEvent} plus the `options` parameter described below.
*
* @param {Object} [scope] The scope (`this` reference) in which the handler function is
* executed. **If omitted, defaults to the object which fired the event.**
*
* @param {Object} [options] An object containing handler configuration.
*
* **Note:** Unlike in ExtJS 3.x, the options object will also be passed as the last
* argument to every event handler.
*
* This object may contain any of the following properties:
*
* @param {Object} options.scope
* The scope (`this` reference) in which the handler function is executed. **If omitted,
* defaults to the object which fired the event.**
*
* @param {Number} options.delay
* The number of milliseconds to delay the invocation of the handler after the event fires.
*
* @param {Boolean} options.single
* True to add a handler to handle just the next firing of the event, and then remove itself.
*
* @param {Number} options.buffer
* Causes the handler to be scheduled to run in an {@link Ext.util.DelayedTask} delayed
* by the specified number of milliseconds. If the event fires again within that time,
* the original handler is _not_ invoked, but the new handler is scheduled in its place.
*
* @param {Ext.util.Observable} options.target
* Only call the handler if the event was fired on the target Observable, _not_ if the event
* was bubbled up from a child Observable.
*
* @param {String} options.element
* **This option is only valid for listeners bound to {@link Ext.Component Components}.**
* The name of a Component property which references an element to add a listener to.
*
* This option is useful during Component construction to add DOM event listeners to elements of
* {@link Ext.Component Components} which will exist only after the Component is rendered.
* For example, to add a click listener to a Panel's body:
*
* new Ext.panel.Panel({
* title: 'The title',
* listeners: {
* click: this.handlePanelClick,
* element: 'body'
* }
* });
*
* **Combining Options**
*
* Using the options argument, it is possible to combine different types of listeners:
*
* A delayed, one-time listener.
*
* myPanel.on('hide', this.handleClick, this, {
* single: true,
* delay: 100
* });
