better-dateinput-polyfill

input[type=date] polyfill for better-dom

Why another date picker? The problem is that most of existing solutions do not follow standards regarding to value property format, that should have “a valid full-date as defined in [RFC 3339]”. In other words representation of date can vary, but the string value should have yyyy-MM-dd format. It helps to work with such values consistently regarding on the current language.

Installation

The simplest way is to use bower:

$ bower install better-dateinput-polyfill

This will clone the latest version of the better-dateinput-polyfill with dependencies into the bower_components directory at the root of your project.

Then append the following script on your page:

<script src="bower_components/better-dom/dist/better-dom.js"></script>
<script src="bower_components/better-i18n-plugin/dist/better-i18n-plugin.js"></script>
<script src="bower_components/better-dateinput-polyfill/dist/better-dateinput-polyfill.js"></script>

Custom formats

Displayed date can be formatted using a data-format attribute on the <input type="date">. For example:

<input type="date" data-format="EE, MMMM dd'th' yyyy">

This will display the selected date like "Monday, December 8th 2014" on the input.

If data-format is not specified, date is formatted using the pattern "E, dd MMM yyyy".

Possible parameters for the format are:

Letter	Date Component	Presentation	Examples
y	Year	Year	2002; 02; 2
M	Month in year	Month	July; Jul; 07; 7
w	Week in year	Number	07; 7
W	Week in month	Number	2
D	Day in year	Number	009; 9
d	Day in month	Number	08; 8
F	Day of week in month (1st, 2nd, 3rd Tuesday)	Number	2
E	Day name in week	Text	Tuesday; Tu.
u	Day number of week (1 = Monday, ..., 7 = Sunday)	Number	1

Number of letters in the parameter name specifies form of the output value, for instance:

"M" yields "1"
"MM" yields "01"
"MMM" yields "Jan"
"MMMM" yields "January"
