How to display number of days selected from two dates selected from Zebra Datepicker?
Here is the javascript. I was able to start Zebra Datepicker but was unable to display the number of days.
<script type="text/javascript">
$(function() {
$('#mystartdate').Zebra_DatePicker({
direction: 3, // represents the earliest start day from now
select_other_months: 1,
pair: $('#myenddate'),
format: 'm/d/Y'
});
$('#myenddate').Zebra_DatePicker({
direction: [1, 30], // represents 30 days from the selected date
select_other_months: 1,
format: 'm/d/Y'
});
});
</script>
<script type="text/javascript">
function showDays() {
var start = $('#mystartdate').data('Zebra_DatePicker');
var end = $('#myenddate').data('Zebra_DatePicker');
if (!start || !end) return;
var days = (end - start) / 1000 / 60 / 60 / 24;
$('#num_nights').val(days);
};
</script>
Here is the HTML:
<input type="text" name="xstartdate" class="form-control input-sm" id="mystartdate" placeholder="Required">
<input type="text" name="xenddate" class="form-control input-sm" id="myenddate" placeholder="Required">
<input type="text" id="num_nights" readonly>

Few things are missing:
- Call
showDays()
after user selects date. This can be done withonClose
(called when the date token is closed). - Use
val()
to get dates. - Parse the date and then do the calculation.
$(document).ready(function() {
$(function() {
$('#mystartdate').Zebra_DatePicker({
direction: 3, // represents the earliest start day from now
select_other_months: 1,
pair: $('#myenddate'),
format: 'm/d/Y',
onClose: function(el) {
showDays(el);
}
});
$('#myenddate').Zebra_DatePicker({
direction: [1, 30], // represents 30 days from the selected date
select_other_months: 1,
format: 'm/d/Y',
onClose: function(el) {
showDays(el);
}
});
});
function showDays() {
// get date
var start = $('#mystartdate').val();
var end = $('#myenddate').val();
if (!start || !end) return;
// parse date
var startArr = start.split("/");
var endArr = end.split("/");
var startDate = new Date(startArr[2], startArr[0] - 1, startArr[1]);
var endDate = new Date(endArr[2], endArr[0] - 1, endArr[1]);
// calculate days
var days = Math.round((endDate-startDate)/(1000*60*60*24));
$('#num_nights').val(days);
};
});
