Many classes have shortcut names used when creating (instantiating) a class with a
configuration object. The shortcut name is referred to as an alias (or xtype if the
class extends Ext.Component). The alias/xtype is listed next to the class name of
applicable classes for quick reference.
Framework classes or their members may be specified as private or protected. Else,
the class / member is public. Public, protected, and private are access
descriptors used to convey how and when the class or class member should be used.
Public classes and class members are available for use by any other class or application code and may be relied upon as a stable and persistent within major product versions. Public classes and members may safely be extended via a subclass.
Protected class members are stable public members intended to be used by the
owning class or its subclasses. Protected members may safely be extended via a subclass.
Private classes and class members are used internally by the framework and are not intended to be used by application developers. Private classes and members may change or be omitted from the framework at any time without notice and should not be relied upon in application logic.
static label next to the
method name. *See Static below.Below is an example class member that we can disect to show the syntax of a class member (the lookupComponent method as viewed from the Ext.button.Button class in this case).
Let's look at each part of the member row:
lookupComponent in this example)( item ) in this example)Ext.Component in this case). This may be omitted for methods that do not
return anything other than undefined or may display as multiple possible values
separated by a forward slash / signifying that what is returned may depend on the
results of the method call (i.e. a method may return a Component if a get method calls is
successful or false if unsuccessful which would be displayed as
Ext.Component/Boolean).PROTECTED in
this example - see the Flags section below)Ext.container.Container in this example). The source
class will be displayed as a blue link if the member originates from the current class
and gray if it is inherited from an ancestor or mixed-in class.view source in the example)item : Object in the example).undefined a "Returns" section
will note the type of class or object returned and a description (Ext.Component in the
example)Available since 3.4.0 - not pictured in
the example) just after the member descriptionDefaults to: false)The API documentation uses a number of flags to further commnicate the class member's function and intent. The label may be represented by a text label, an abbreviation, or an icon.

Just below the class name on an API doc page is a row of buttons corresponding to the types of members owned by the current class. Each button shows a count of members by type (this count is updated as filters are applied). Clicking the button will navigate you to that member section. Hovering over the member-type button will reveal a popup menu of all members of that type for quick navigation.
Getting and setter methods that correlate to a class config option will show up in the methods section as well as in the configs section of both the API doc and the member-type menus just beneath the config they work with. The getter and setter method documentation will be found in the config row for easy reference.
Your page history is kept in localstorage and displayed (using the available real estate) just below the top title bar. By default, the only search results shown are the pages matching the product / version you're currently viewing. You can expand what is displayed by clicking on the button on the right-hand side of the history bar and choosing the "All" radio option. This will show all recent pages in the history bar for all products / versions.
Within the history config menu you will also see a listing of your recent page visits. The results are filtered by the "Current Product / Version" and "All" radio options. Clicking on the button will clear the history bar as well as the history kept in local storage.
If "All" is selected in the history config menu the checkbox option for "Show product details in the history bar" will be enabled. When checked, the product/version for each historic page will show alongside the page name in the history bar. Hovering the cursor over the page names in the history bar will also show the product/version as a tooltip.
Both API docs and guides can be searched for using the search field at the top of the page.
On API doc pages there is also a filter input field that filters the member rows using the filter string. In addition to filtering by string you can filter the class members by access level, inheritance, and read only. This is done using the checkboxes at the top of the page.
The checkbox at the bottom of the API class navigation tree filters the class list to include or exclude private classes.
Clicking on an empty search field will show your last 10 searches for quick navigation.
Each API doc page (with the exception of Javascript primitives pages) has a menu view of metadata relating to that class. This metadata view will have one or more of the following:
Ext.button.Button class has an alternate class name of Ext.Button). Alternate class
names are commonly maintained for backward compatibility.Runnable examples (Fiddles) are expanded on a page by default. You can collapse and expand example code blocks individually using the arrow on the top-left of the code block. You can also toggle the collapse state of all examples using the toggle button on the top-right of the page. The toggle-all state will be remembered between page loads.
Class members are collapsed on a page by default. You can expand and collapse members using the arrow icon on the left of the member row or globally using the expand / collapse all toggle button top-right.
Viewing the docs on narrower screens or browsers will result in a view optimized for a smaller form factor. The primary differences between the desktop and "mobile" view are:
The class source can be viewed by clicking on the class name at the top of an API doc page. The source for class members can be viewed by clicking on the "view source" link on the right-hand side of the member row.
This class defines some basic methods for handling dates.
The date parsing and formatting syntax contains a subset of
PHP's date() function, and the formats that are
supported will provide results equivalent to their PHP versions.
The following is a list of all currently supported formats:
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 Numeric representation of a month, with leading zeros 01 to 12
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 represented as the local time with an offset to UTC appended.
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
date-time granularity which are supported, or see 2000-02-13T21:25:33
http://www.w3.org/TR/NOTE-datetime for more info. 2001-01-12 22:26:34
C An ISO date string as implemented by the native Date object's 1962-06-17T09:21:34.125Z
[Date.toISOString](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)
method. This outputs the numeric part with *UTC* hour and minute
values, and indicates this by appending the `'Z'` timezone
identifier.
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)\/
time A javascript millisecond timestamp 1350024476440
timestamp A UNIX timestamp (same as U) 1350024866
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
Here are some standard date/time patterns that you might find helpful. They are not part of the source of Ext.Date, but to use them you can simply copy this block of code into any script that is included after Ext.Date and they will also become globally available on the Date object. Feel free to add or remove patterns as needed in your code.
Ext.Date.patterns = {
ISO8601Long:"Y-m-d H:i:s",
ISO8601Short:"Y-m-d",
ShortDate: "n/j/Y",
LongDate: "l, F d, Y",
FullDateTime: "l, F d, Y g:i:s A",
MonthDay: "F d",
ShortTime: "g:i A",
LongTime: "g:i:s A",
SortableDateTime: "Y-m-d\\TH:i:s",
UniversalSortableDateTime: "Y-m-d H:i:sO",
YearMonth: "F, Y"
};
Example usage:
var dt = new Date();
console.log(Ext.Date.format(dt, Ext.Date.patterns.ShortDate));
Developer-written, custom formats may be used by supplying both a formatting and a parsing function which perform to specialized requirements. The functions are stored in parseFunctions and formatFunctions.
An array of textual day names. Override these values for international dates.
Example:
Ext.Date.dayNames = [
'SundayInYourLang',
'MondayInYourLang'
// ...
];
Defaults to:
[
"Sunday",
"Monday",
"Tuesday",
"Wednesday",
"Thursday",
"Friday",
"Saturday"
]
The date format string that the Ext.util.Format#dateRenderer and Ext.util.Format#date functions use. See Ext.Date for details.
This may be overridden in a locale file.
Defaults to:
"m/d/Y"
An object hash containing default date values used during date parsing.
The following properties are available:
y: Number - The default year value. Defaults to undefined.m: Number - The default 1-based month value. Defaults to undefined.d: Number - The default day value. Defaults to undefined.h: Number - The default hour value. Defaults to undefined.i: Number - The default minute value. Defaults to undefined.s: Number - The default second value. Defaults to undefined.ms: Number - The default millisecond value. Defaults to undefined.Override these properties to customize the default date values used by the parse method.
Note: In countries which experience Daylight Saving Time (i.e. DST), the h, i, s
and ms properties may coincide with the exact time in which DST takes effect.
It is the responsibility of the developer to account for this.
Example Usage:
// set default day value to the first day of the month
Ext.Date.defaults.d = 1;
// parse a February date string containing only year and month values.
// setting the default day value to 1 prevents weird date rollover issues
// when attempting to parse the following date string on, for example, March 31st 2009.
Ext.Date.parse('2009-02', 'Y-m'); // returns a Date object representing February 1st 2009.
Defaults to:
{}
The base format-code to formatting-function hashmap used by the format method. Formatting functions are strings (or functions which return strings) which will return the appropriate value when evaluated in the context of the Date object from which the format method is called. Add to / override these mappings for custom date formatting.
Note: Ext.Date.format() treats characters as literals if an appropriate mapping cannot be found.
Example:
Ext.Date.formatCodes.x = "Ext.util.Format.leftPad(this.getDate(), 2, '0')";
console.log(Ext.Date.format(new Date(), 'X'); // returns the current day of the month
Defaults to:
{
d: "Ext.String.leftPad(m.getDate(), 2, '0')",
D: "Ext.Date.getShortDayName(m.getDay())",
// get localized short day name
j: "m.getDate()",
l: "Ext.Date.dayNames[m.getDay()]",
N: "(m.getDay() ? m.getDay() : 7)",
S: "Ext.Date.getSuffix(m)",
w: "m.getDay()",
z: "Ext.Date.getDayOfYear(m)",
W: "Ext.String.leftPad(Ext.Date.getWeekOfYear(m), 2, '0')",
F: "Ext.Date.monthNames[m.getMonth()]",
m: "Ext.String.leftPad(m.getMonth() + 1, 2, '0')",

Y: "Ext.String.leftPad(m.getFullYear(), 4, '0')",
y: "('' + m.getFullYear()).substring(2, 4)",
a: "(m.getHours() < 12 ? 'am' : 'pm')",

i: "Ext.String.leftPad(m.getMinutes(), 2, '0')",
s: "Ext.String.leftPad(m.getSeconds(), 2, '0')",
u: "Ext.String.leftPad(m.getMilliseconds(), 3, '0')",
O: "Ext.Date.getGMTOffset(m)",
P: "Ext.Date.getGMTOffset(m, true)",
T: "Ext.Date.getTimezone(m)",
Z: "(m.getTimezoneOffset() * -60)",
c: function() {
// ISO-8601 -- GMT format
var c = "Y-m-dTH:i:sP",
code = [],
i,
l = c.length,
e;
for (i = 0; i < l; ++i) {
e = c.charAt(i);
code.push(e === "T" ? "'T'" : utilDate.getFormatCode(e));
}
// treat T as a character literal
return code.join(" + ");
},
C: function() {
// ISO-1601 -- browser format. UTC numerics with the 'Z' TZ id.
return 'm.toISOString()';
},
U: "Math.round(m.getTime() / 1000)"
}
An object hash in which each property is a date formatting function. The property name is the format string which corresponds to the produced formatted date string.
This object is automatically populated with date formatting functions as date formats are requested for Ext standard formatting strings.
Custom formatting functions may be inserted into this object, keyed by a name which from then on may be used as a format string to format.
Example:
Ext.Date.formatFunctions['x-date-format'] = myDateFormatter;
A formatting function should return a string representation of the Date object which is the scope (this) of the function.
To enable date strings to also be parsed according to that format, a corresponding parsing function must be placed into the parseFunctions property.
Defaults to:
{
"MS": function() {
// UTC milliseconds since Unix epoch (MS-AJAX serialized date format (MRSF))
return '\\/Date(' + this.getTime() + ')\\/';
},
"time": function() {
return this.getTime().toString();
},
"timestamp": function() {
return utilDate.format(this, 'U');
}
}
An array of textual month names. Override these values for international dates.
Example:
Ext.Date.monthNames = [
'JanInYourLang',
'FebInYourLang'
// ...
];
Defaults to:
[
"January",
"February",
"March",
"April",
"May",
"June",
"July",
"August",
"September",
"October",
"November",
"December"
]
An object hash of zero-based JavaScript month numbers (with short month names as keys).
Note: keys are case-sensitive.
Override these values for international dates.
Example:
Ext.Date.monthNumbers = {
'LongJanNameInYourLang': 0,
'ShortJanNameInYourLang':0,
'LongFebNameInYourLang':1,
'ShortFebNameInYourLang':1
// ...
};
Defaults to:
{
January: 0,
Jan: 0,
February: 1,
Feb: 1,
March: 2,
Mar: 2,
April: 3,
Apr: 3,
May: 4,

September: 8,
Sep: 8,
October: 9,

An object hash in which each property is a date parsing function. The property name is the format string which that function parses.
This object is automatically populated with date parsing functions as date formats are requested for Ext standard formatting strings.
Custom parsing functions may be inserted into this object, keyed by a name which from then on may be used as a format string to parse.
Example:
Ext.Date.parseFunctions['x-date-format'] = myDateParser;
A parsing function should return a Date object, and is passed the following parameters:
date: String - The date string to parse.strict: Boolean - true to validate date strings while parsing
(i.e. prevent JavaScript Date "rollover"). The default must be false.
Invalid date strings should return null when parsed.To enable Dates to also be formatted according to that format, a corresponding formatting function must be placed into the formatFunctions property.
Defaults to:
{
"MS": function(input, strict) {
// note: the timezone offset is ignored since the MS Ajax server sends
// a UTC milliseconds-since-Unix-epoch value (negative values are allowed)
var r = (input || '').match(MSFormatRe);
return r ? new nativeDate(((r[1] || '') + r[2]) * 1) : null;
},
"time": function(input, strict) {
var num = parseInt(input, 10);
if (num || num === 0) {
return new nativeDate(num);
}
return null;
},
"timestamp": function(input, strict) {
var num = parseInt(input, 10);
if (num || num === 0) {
return new nativeDate(num * 1000);
}
return null;
}
}
Provides a convenient method for performing basic date arithmetic. This method does not modify the Date instance being called - it creates and returns a new Date instance containing the resulting date value.
Examples:
// Basic usage:
var dt = Ext.Date.add(new Date('10/29/2006'), Ext.Date.DAY, 5);
console.log(dt); // returns 'Fri Nov 03 2006 00:00:00'
// Negative values will be subtracted:
var dt2 = Ext.Date.add(new Date('10/1/2006'), Ext.Date.DAY, -5);
console.log(dt2); // returns 'Tue Sep 26 2006 00:00:00'
// Decimal values can be used:
var dt3 = Ext.Date.add(new Date('10/1/2006'), Ext.Date.DAY, 1.25);
console.log(dt3); // returns 'Mon Oct 02 2006 06:00:00'

clone : Boolean (optional)
true to create a clone of this date, clear the time and return it.
Defaults to: false
this or the clone.
Creates and returns a new Date instance with the exact same date value as the called instance. Dates are copied and passed by reference, so if a copied date variable is modified later, the original variable will also be changed. When the intention is to create a new variable that will not modify the original instance, you should create a clone.
Example of correctly cloning a date:
//wrong way:
var orig = new Date('10/1/2006');
var copy = orig;
copy.setDate(5);
console.log(orig); // returns 'Thu Oct 05 2006'!
//correct way:
var orig = new Date('10/1/2006'),
copy = Ext.Date.clone(orig);
copy.setDate(5);
console.log(orig); // returns 'Thu Oct 01 2006'

Get the timezone abbreviation of the current date (equivalent to the format specifier 'T').
Note: The date string returned by the JavaScript Date object's toString() method varies
between browsers (e.g. FF vs IE) and system region settings (e.g. IE in Asia vs IE in America).
For a given date string e.g. "Thu Oct 25 2007 22:55:35 GMT+0800 (Malay Peninsula Standard Time)",
getTimezone() first tries to get the timezone abbreviation from between a pair of parentheses
(which may or may not be present), failing which it proceeds to get the timezone abbreviation
from the GMT offset portion of the date string.

true if the passed parameters do not cause a Date "rollover", false otherwise.
Parses the passed string using the specified date format.
Note that this function expects normal calendar dates, meaning that months are 1-based (i.e. 1 = January).
The defaults hash will be used for any date value (i.e. year, month, day, hour, minute, second or millisecond)
which cannot be found in the passed string. If a corresponding default date value has not been specified in the defaults hash,
the current date's year, month, day or DST-adjusted zero-hour time value will be used instead.
Keep in mind that the input date string must precisely match the specified format string
in order for the parse operation to be successful (failed parse operations return a
null value).
Example:
//dt = Fri May 25 2007 (current date)
var dt = new Date();
//dt = Thu May 25 2006 (today's month/day in 2006)
dt = Ext.Date.parse("2006", "Y");
//dt = Sun Jan 15 2006 (all date parts specified)
dt = Ext.Date.parse("2006-01-15", "Y-m-d");
//dt = Sun Jan 15 2006 15:20:01
dt = Ext.Date.parse("2006-01-15 3:20:01 PM", "Y-m-d g:i:s A");
// attempt to parse Sun Feb 29 2006 03:20:01 in strict mode
dt = Ext.Date.parse("2006-02-29 03:20:01", "Y-m-d H:i:s", true); // returns null
input : String
The raw date string.
format : String
The expected date string format.
strict : Boolean (optional)
true to validate date strings while parsing (i.e. prevents JavaScript Date "rollover").
Invalid date strings will return null when parsed.
Defaults to: false
The parsed Date, or null if an invalid date string.
Provides a convenient method for performing basic date arithmetic. This method does not modify the Date instance being called - it creates and returns a new Date instance containing the resulting date value.
Examples:
// Basic usage:
var dt = Ext.Date.subtract(new Date('10/29/2006'), Ext.Date.DAY, 5);
console.log(dt); // returns 'Tue Oct 24 2006 00:00:00'
// Negative values will be added:
var dt2 = Ext.Date.subtract(new Date('10/1/2006'), Ext.Date.DAY, -5);
console.log(dt2); // returns 'Fri Oct 6 2006 00:00:00'
// Decimal values can be used:
var dt3 = Ext.Date.subtract(new Date('10/1/2006'), Ext.Date.DAY, 1.25);
console.log(dt3); // returns 'Fri Sep 29 2006 06:00:00'
