How to restrict jqueryui date range? - jquery-ui

Question

I have two date-pickers #from and #to, as usual, now what I need to do is make sure that the date range selected between the two is always within 3months of each other. So basically, on selecting one of the pickers, I need to set minDate/maxDate option for the other one relative to the selected date, But I don't know what would be the best way to find these relative dates. Any suggestions?

Answer 1

Alternatively you could do it like this:fiddle
Both ways are valid, i suppose.
.js
$("#startDatePicker").datepicker({
dateFormat: 'yy-mm-dd',
onSelect: function(dateText,dateObj){
var dateObject = $(this).datepicker("getDate");
dateObject.setMonth(dateObj.currentMonth+3);
$("#endDatePicker").datepicker( "option", "maxDate",dateObject);
}
});
$("#endDatePicker").datepicker({
dateFormat: 'yy-mm-dd',
changeMonth: true,
onSelect: function(dateText,dateObj){
var dateObject = $(this).datepicker("getDate");
dateObject.setMonth(dateObj.currentMonth-3);
$("#startDatePicker").datepicker( "option", "minDate",dateObject);
}
});

Answer 2

I have created a jsfiddle.The range between the days is set to 3 days.you can edit based on ur requirement
$(document).ready(function () {
$("#startDatePicker").datepicker({
dateFormat: 'yy-mm-dd',
onSelect: function (date) {
if ($('#endDatePicker').val() == "") {
var selectedDate = new Date(date);
var secsPerDay = 86400000;
var endDate = new Date(selectedDate.getTime() + 2 * secsPerDay);
alert(endDate);
$("#endDatePicker").datepicker("option", "minDate", selectedDate);
$("#endDatePicker").datepicker("option", "maxDate", endDate);
}
}
});
$("#endDatePicker").datepicker({
dateFormat: 'yy-mm-dd',
changeMonth: true,
onSelect: function (date) {
if ($('#startDatePicker').val() == "") {
var selectedDate = new Date(date);
var secsPerDay = 86400000;
var startDate = new Date(selectedDate.getTime() - 5 * secsPerDay);
$("#startDatePicker").datepicker("option", "minDate", startDate);
$("#startDatePicker").datepicker("option", "maxDate", selectedDate);
}
}
});
});
and HTML
<p>Start Date:
<input type="text" id="startDatePicker"/>
</p>
<p>End Date:
<input type="text" id="endDatePicker"/>
</p>
