A jQuery plugin that converts a date object to a supplied format. It was forked from the jQuery UI DatePicker module to support time formatting as well as the original date formatting.

Refer to the dist directory for versions of the library which can be used directly in your application.

The plugin supports the following formatting combinations:

a  - ante meridiem and post meridiem
d  - day of month (no leading zero)
dd - day of month (two digit)
o  - day of year (no leading zeros)
oo - day of year (three digit)
D  - day name short
DD - day name long
g  - 12-hour hour format of day (no leading zero)
gg - 12-hour hour format of day (two digit)
h  - 24-hour hour format of day (no leading zero)
hh - 24-hour hour format of day (two digit)
u  - millisecond of second (no leading zeros)
uu - millisecond of second (three digit)
i  - minute of hour (no leading zero)
ii - minute of hour (two digit)
m  - month of year (no leading zero)
mm - month of year (two digit)
M  - month name short
MM - month name long
S  - ordinal suffix for the previous unit
s  - second of minute (no leading zero)
ss - second of minute (two digit)
y  - year (two digit)
yy - year (four digit)
@  - Unix timestamp (ms since 01/01/1970)
!  - Windows ticks (100ns since 01/01/0001)
'...' - literal text
'' - single quote

Calling the function with a date.

$.formatDateTime('mm/dd/y g:ii a', new Date('2012/07/05 09:55:03')); // 07/05/12 9:55 AM
$.formatDateTime('mm/dd/y gg:ii:ss.uu a', new Date('2012/01/01 00:00:00.000')); // 01/01/12 12:00:00.000 AM

Using an element attribute, e.g.

<span id="example" data-datetime="2012/07/05 09:55:03" />

and calling

$('#example').formatDateTime('mm/dd/y g:ii a');

will produce

<span id="example" data-datetime="2012/07/05 09:55:03">07/05/12 9:55 AM</span>

Or you can specify the date format in the data-dateformat attribute in the element, e.g.

<span id="example" data-datetime="2012/07/05 09:55:03" data-dateformat="mm/dd/y g:ii a">07/05/12 9:55 AM</span>

and calling

$('#example').formatDateTime()

will produce

<span id="example" data-datetime="2012/07/05 09:55:03" data-dateformat="mm/dd/y g:ii a">07/05/12 9:55 AM</span>

Or it can override the text of an element, e.g.

<span id="example">2012/07/05 09:55:03</span>

By calling

$('#example').formatDateTime('mm/dd/y g:ii a');

will produce

<span id="example">07/05/12 9:55 AM</span>

The defaults for formatting are all in English and use traditional capitalization, e.g. Monday, AM and August. This may not be appropriate for all applications. To override these defaults on a case-by-case basis, pass settings to formatDateTime, e.g.

$.formatDateTime('mm/dd/y g:ii a', new Date('2012/07/05 09:55:03'), {ampmNames: ['am', 'pm']}); // 07/05/12 9:55 am

To permanently change the plugin defaults for your application, redefine them directly, e.g.

$.formatDateTime.defaults['ampmNames'] = ['am', 'pm'];
$.formatDateTime('mm/dd/y g:ii a', new Date('2012/07/05 09:55:03')); // 07/05/12 9:55 am

Available settings are as follows:

• monthNames: names of the months, e.g. January
• monthNamesShort: shortened names of the months, e.g. Jan
• dayNames: names of the days, e.g. Sunday
• dayNamesShort: shortened names of the days, e.g. Sun
• ampmNames: names of the 12-hour clock periods, e.g. AM
• getSuffix: callback to convert number to ordinal suffix, e.g. 1 to st
• attribute: attribute which contains the datetime
• formatAttribute: attribute which contains the datetime format
• utc: render dates in UTC instead of local timezone

This project is managed using grunt. To initialize the project, run

$ npm install -g grunt-cli

Once initialized, run

$ grunt

This will run all the tasks needed for building and testing the library. It will produce deployable versions of the library in the dist directory. For convenience to users who may not want to build the application, they are also included in the repository and should be included as part of any commits back to the repository.

Tests are run using Jasmine via the grunt jasmine plugin. They can be run once your environment has been set up (see Contributing for more details) by issuing

$ grunt test

This will perform all tests of the library against jQuery versions 1.5 to 2.1.
