ExtReact Docs Help

Introduction

The documentation for the ExtReact product diverges somewhat from the documentation of other Sencha products. The sections below describe documentation for all products except where indicated as unique to ExtReact.

Terms, Icons, and Labels

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.

ExtReact component classes list the configurable name prominently at the top of the API class doc followed by the fully-qualified class name.

Access Levels

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.

Member Types

Member Syntax

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).

lookupComponent ( item ) : Ext.Component
protected

Called when a raw config object is added to this container either during initialization of the items config, or when new items are added), or {@link #insert inserted.

This method converts the passed object into an instanced child component.

This may be overridden in subclasses when special processing needs to be applied to child creation.

Parameters

item :  Object

The config object being added.

Returns
Ext.Component

The component to be added.

Let's look at each part of the member row:

Member Flags

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.

Class Icons

- Indicates a framework class

- A singleton framework class. *See the singleton flag for more information

- A component-type framework class (any class within the Ext JS framework that extends Ext.Component)

- Indicates that the class, member, or guide is new in the currently viewed version

Member Icons

- Indicates a class member of type config

Or in the case of an ExtReact component class this indicates a member of type prop

- Indicates a class member of type property

- Indicates a class member of type method

- Indicates a class member of type event

- Indicates a class member of type theme variable

- Indicates a class member of type theme mixin

- Indicates that the class, member, or guide is new in the currently viewed version

Class Member Quick-Nav Menu

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.

Getter and Setter Methods

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.

ExtReact component classes do not hoist the getter / setter methods into the prop. All methods will be described in the Methods section

History Bar

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.

Search and Filters

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.

API Doc Class Metadata

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:

Expanding and Collapsing Examples and Class Members

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.

Desktop -vs- Mobile View

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:

Viewing the Class Source

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.

Summary

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

             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

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.

properties

Instance Properties

DAY : String

Date interval constant.

Defaults to:

"d"

dayNames : String[]

An array of textual day names. Override these values for international dates.

Example:

Ext.Date.dayNames = [
    'SundayInYourLang',
    'MondayInYourLang'
    // ...
];

DAYS_IN_WEEK : Number

The number of days in a week.

Defaults to:

7

defaultFormat : String

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"

defaults : Object

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.

firstDayOfWeek : Number

The day on which the week starts. 0 being Sunday, through 6 being Saturday.

This may be overridden in a locale file.

Defaults to:

0

formatCodes : Object

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

formatFunctions : Object

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.

HOUR : String

Date interval constant.

Defaults to:

"h"

MILLI : String

Date interval constant.

Defaults to:

"ms"

MINUTE : String

Date interval constant.

Defaults to:

"mi"

MONTH : String

Date interval constant.

Defaults to:

"mo"

monthNames : String[]

An array of textual month names. Override these values for international dates.

Example:

Ext.Date.monthNames = [
    'JanInYourLang',
    'FebInYourLang'
    // ...
];

monthNumbers : Object

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
    // ...
};

MONTHS_IN_YEAR : Number

The number of months in a year.

Defaults to:

12

MONTHS_IN_YEAR : Number

The maximum number of days in a month.

Defaults to:

31

SECOND : String

Date interval constant.

Defaults to:

"s"

useStrict : Boolean

Global flag which determines if strict date parsing should be used. Strict date parsing will not roll-over invalid dates, which is the default behavior of JavaScript Date objects. (see parse for more information)

Defaults to:

false

weekendDays : Number[]

The days on which weekend falls. 0 being Sunday, through 6 being Saturday.

This may be overridden in a locale file.

Defaults to:

[0,6]

YEAR : String

Date interval constant.

Defaults to:

"y"

methods

Instance Methods

add ( date, interval, value, [preventDstAdjust] ) : Date

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'

Parameters

date :  Date

The date to modify

interval :  String

A valid date interval enum value.

value :  Number

The amount to add to the current date.

preventDstAdjust :  Boolean (optional)

true to prevent adjustments when crossing daylight savings boundaries.

Defaults to: false

Returns

:Date

The new Date instance.

align ( date, unit, step ) : Date

Align the date to unit.

Parameters

date :  Date

The date to be aligned.

unit :  String

The unit. This unit is compatible with the date interval constants.

step :  Number

Returns

:Date

The aligned date.

between ( date, start, end ) : Boolean

Checks if a date falls on or between the given start and end dates.

Parameters

date :  Date

The date to check

start :  Date

Start date

end :  Date

End date

Returns

:Boolean

true if this date falls on or between the given start and end dates.

clearTime ( date, [clone] ) : Date

Attempts to clear all time information from this Date by setting the time to midnight of the same day, automatically adjusting for Daylight Saving Time (DST) where applicable.

Note: DST timezone information for the browser's host operating system is assumed to be up-to-date.

Parameters

date :  Date

The date

clone :  Boolean (optional)

true to create a clone of this date, clear the time and return it.

Defaults to: false

Returns

:Date

this or the clone.

clone ( date ) : Date

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'

Parameters

date :  Date

The date.

Available since: 6.2.0

Parameters

d :  Date

The date to convert.

Returns

:Date

The date as UTC. Does not modify the passed date.

parse ( input, format, [strict] ) : Date/null

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&#39;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

Parameters

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

Returns

:Date/null

The parsed Date, or null if an invalid date string.

parseFunctions : Object

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.

Properties

parseFunctions :

subtract ( date, interval, value, [preventDstAdjust] ) : Date

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'

Parameters

date :  Date

The date to modify

interval :  String

A valid date interval enum value.

value :  Number

The amount to subtract from the current date.

preventDstAdjust :  Boolean (optional)

true to prevent adjustments when crossing daylight savings boundaries.
