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.
Features
- lightweight polyfill with no dependencies
- works for initial and dynamic content elements
- normalizes
input[type=date]
presentation for desktop browsers - submitted value always has standards based
yyyy-MM-dd
[RFC 3339] format placeholder
attribute works as expected- it's possible to change displayed date value format
- you are able to control where to apply the polyfill
- keyboard and accessibility friendly
Installation
$ npm install better-dateinput-polyfill
Then append the following scripts to your page:
<script src="node_modules/better-dateinput-polyfill/dist/better-dateinput-polyfill.js"></script>
Forcing the polyfill
Sometimes it's useful to override browser implemetation with the consistent control implemented by the polyfill. To suppress feature detection you can add <meta name="dateinput-polyfill-media">
into your document <head>
. Value of content
attribute is a media query where polyfill will be applied:
<!-- force polyfill everywhere -->
<meta name="dateinput-polyfill-media" content="screen">
<!-- force polyfill only on mobile devices in portrait mode-->
<meta name="dateinput-polyfill-media" content="screen and (orientation: portrait)">
Change default date presentation format
When no spicified polyfill uses browser settings to format displayed date. You can override date presentation globally with <meta name="dateinput-polyfill-format">
via content
attribute or directly on a HTML element with data-format
attribute. Value should be options for the Date#toLocaleString call as a stringified JSON object:
<html>
<head>
<!-- Override default date presentation format -->
<meta name="dateinput-polyfill-format" content='{"month":"long","year":"numeric","day":"numeric"}'>
</head>
<body>
<!-- Override date presentation format on a particular element -->
<input type="date" data-format='{"month":"short","year":"numeric","day":"numeric"}'>
</body>
</html>
