Jquery Ui Datepicker Difference In Days

I need to calculate the number of weeks difference between the chosen date and the current date. I've tried to calculate with weekNumberPicked - weekNumberCurrent, but if the two d

Solution 1:

You can use the Datepicker's function getDate to get a Date object.

Then just subtract one date from the other (might want to get the absolute value as well) to get the milliseconds in difference, and calculate the difference in days, or weeks.

$('#test').datepicker({
    onSelect: function() {
        var date = $(this).datepicker('getDate');
        var today = newDate();
        var dayDiff = Math.ceil((today - date) / (1000 * 60 * 60 * 24));
    }
});

Solution 2:

Since DatePicker getDate() methode returns a javascript Date object, you can do something like :

var myDate = $('.datepicker').datepicker('getDate');
var current = newDate();
var difference = myDate - current;

difference now contains the number of milliseconds between your two dates , you can easily compute the number of weeks :

var weeks = difference / 1000 / 60 / 60 / 24 / 7;

Solution 3:

try this code and applied it to your work :D

$("#date_born").datepicker({
    onSelect: function () {
        var start = $('#date_born').datepicker('getDate');
        var end   = newDate();
        var age_year   = Math.floor((end - start)/31536000000);
        var age_month   = Math.floor(((end - start)% 31536000000)/2628000000);
        var age_day   = Math.floor((((end - start)% 31536000000) % 2628000000)/86400000);
        $('#age').val(age_year +' year ' + age_month + ' month ' + age_day + ' day');
    },
    dateFormat: 'dd/mm/yy',
    maxDate: '+0d',     
    yearRange: '1914:2014',
    buttonImageOnly: false,
    changeMonth: true,
    changeYear: true
});

Html Code:

Date <inputtype="text" name="date_born"id="date_born"/> 
Age <inputtype="text" name="age"id="age" />
