我想计算使用jQuery日期选择器选择日期时的年龄。我在下面添加了代码，但是如果我选择 19/03/2015， 15/01/2015或 19/03/2014， 31/12/2014之类的日期，它将显示负值

I want to calculate age when date is selected by using jquery date picker. I added code below but it showing minus value if i select date like '19/03/2015','15/01/2015' or '19/03/2014' ,'31/12/2014'

  $(document).ready(function () 
{
 console.log($(document).width());           
     $('#patientDob').datepicker
    ({
        dateFormat: 'dd/mm/yy',
        changeMonth: true,
        changeYear: true,
        yearRange: '1900:2150',
        maxDate: new Date(),
        inline: true,

             onSelect: function() {
               var birthDay = document.getElementById("patientDob").value;
                var DOB = new Date(birthDay);
                var today = new Date();
                var age = today.getTime() - DOB.getTime();
                age = Math.floor(age / (1000 * 60 * 60 * 24 * 365.25));

                document.getElementById('patientAge').value = age;
            }
     });  

});

推荐答案

AFAIK JavaScript日期需要yyyy / mm / dd，并且您正在发送：

AFAIK The javascript Date requires yyyy/mm/dd, and you are sending:

 var DOB = new Date(birthDay); //  dateFormat: 'dd/mm/yy'

将格式更改为 yyyy / mm / dd并且可以正常工作。

Change format to "yyyy/mm/dd" and will work ok.
