Dzdatetimepicker NPM

DZDateTimePicker

Functional, Extensible & Simple Date and Time picker without any dependencies.

DZDateTimePicker also automatically adds support for:

input[type="date"]
input[type="time"]
input[type="datetime-local"]

if they are not supported natively. You don't have to do anything extra. The library will handle the setup for you. You simply have to query the .value of your original input elements and you're all set.

Demos

On a related note:

All source files are in the src directory.
All distribution files are in the dist directory (which you should use for production sites)

Setup

Via NPM

npm install --save dzdatetimepicker

<script src="dzdatetimepicker-dist.js"></script>

<!-- The stylesheet. You can include your own instead -->
<link rel="stylesheet" href="dzdatetimepicker.css" />

Date Picker Usage

Simply,

<input type="datetime-local" name="epoch-start" />

DZDateTimePicker will allow native browser implementations to take over if they exist. If they don't, the library will do it's own wiring for you.

You can optionally initiate the date picker by wiring up a trigger element like so:

<button 
  class="date-trigger" 
  data-date-max="2016-05-09" 
  data-date-min="2016-01-01" 
  data-onset="didSetDate"
>Trigger</button>

The few important things to note are:

when dzdatetimepicker-dsit.js runs, it automatically finds elements with the class date-trigger and hooks on to them. No futher configuration is required.
You can set additional, optional dataset items like date-max and date-min to control the selectable items within a range. Both are optional, and you can use only one if desired.
the last parameter, onset is required if you need a callback when the user selects a date. This is optional, however, your implementation will require it if you need to update the UI. The implementation for this is intentionally left out.

Timer Picker Usage

Simply,

<input type="time" name="epoch-start" />

You can optionally initiate the time picker by wiring up a trigger element like so:

<div 
  role="button" 
  class="trigger timer-trigger" 
  data-onchange="didSetTime"
>Time Trigger</div>

When the script loads, it automatically hooks on to elements with the class timer-trigger. No other configuration is necessary. Similar to the date picker, the last parameter, onchange is required if you need a callback when the user selects a date. This is optional, however, your implementation will require it if you need to update the UI. The implementation for this is intentionally left out.

The callback, unlike the date picker, responds with an object in the following format:

{
  "string" : "14:26",
  "hours" : 14,
  "minutes" : 26
}

Range Picker Usage

To setup a range picker, include the rangepicker-dist.js file along with the date-picker sources as mentioned above. Then you can can write simple markup as follows:

<div id="range-picker">
  
  <div 
    role="button" 
    class="trigger range-start" 
    data-date-max="2017-05-09" 
    data-date-min="2016-01-01" 
    data-onset="didSetDate"
  >Start</div>
    
  <div 
    role="button" 
    class="trigger range-end" 
    data-date-max="2017-05-09" 
    data-date-min="2016-01-01" 
    data-onset="didSetDate"
  >End</div>
  
</div>

You can then initialise the range picker as follows:

const myRangePicker = new RangePicker(document.getElementById("range-picker"))

The RangePicker will then automatically handle all the setup for you and adjust the min-max ranges for the date picker based on the user's input.

Notes

Both the datepicker and timepicker automatically idenity <input> elements. They hook on to the focus and blur events so the user can use the pickers to set the values directly.
If the pickers detect an <input> element, the pickers will update the value attribute when the user updates their selection.
When not using an <input> element, you can optionally set the attribute data-date-val="" and it'll be updated similarly.
