how to change day by clicking previous / next day buttons using pickadate js

Question

I am using pickadate to choose a date. I am trying to change the selected date by clicking the previous day or next day buttons.

    <form method="post">
    <a href="#">previus day</a>
    <input type="text" id="test" data-value="01/11/2017">
    <a href="#">next  day</a>
    <button type="submit">Submit</button>
    </form>

    <script>
    $('#test').pickadate({format: 'dd/mm/yyyy'});
    </script>

Here is the jsfiddle link: https://jsfiddle.net/kdoo53vg/41/

I am newbie at programming. I would appreciate if you can show me the way to do it. Thanks heaps.

The library you're using does not have built in methods to skip to the next/previous days, however it does expose methods you can use to create the functionality yourself.

On click of the next/prev buttons you can get the currently selected date and then add or subtract a day from it, something like this:

 var picker = $('#test').pickadate({ format: 'dd/mm/yyyy' }).pickadate('picker'); $('#previous_day, #next_day').click(function(e) { e.preventDefault(); setDate($(this).data('diff')); }) function setDate(diff) { var date = new Date(picker.get('select').pick); var newDate = date.setDate(date.getDate() + diff); picker.set('select', newDate) }

You have to add click events to previous/next day links. I don't know this plugin, but if there are functions prev/next, you can use it. If not, you have to read date from input and set next/prev date to it.

You can have next/prev date using Date object

var date = new Date(),
    prevDate = date.setDate(date.getDate() - 1),
    nextDate = date.setDate(date.getDate() - 1);
