# vanilla-datetimerange-picker

## Overview.
A JavaScript component that is a date &amp; time range picker, no need to build, no dependencies except Moment.js, that is inspired by [Dan Grossman's bootstrap-daterangepicker](https://github.com/dangrossman/daterangepicker).

Actually, this program is base on Dan Grossman's bootstrap-daterangepicker (version 3.1).
I just changed the code a bit to not need jquery.

## Requirements
-  [Moment.js](https://momentjs.com/) (version 2.29.1 is recommended.)
### IE11
If you want to use on Internet Explorer 11, include [Polyfill](https://polyfill.io/v3/polyfill.js?ua=ie/11) to use CustomEvent, Object.assign, Element.prototype.closest and Element.prototype.matches features.

## Quick start using CDN.
1. Include Moment.js and Date Range Picker's css and js files in your webpage:
```
<link type="text/css" rel="stylesheet" href="https://cdn.jsdelivr.net/gh/alumuko/vanilla-datetimerange-picker@latest/dist/vanilla-datetimerange-picker.css">

See [simple example page](examples/datetime-example-simple.html).
## Usage
```
new DateRangePicker(bindElement, options, callback);
```

| parameter | type | description |
----|----|---- 
| bindElement | string or object | bind element id or bind HTMLElement object |
| options | object | option set (see Options) |
| callback | function(momemt, moment) | change datetime callback, 2 parameters: start and end datetime |

## Options
