How to determine if the user is 18 years old and up using jquery?

Question

I want to determine if the user is 18 years old and up using jquery. Can anyone give me a sample code. I am using datepicker.

Thanks in advance!

Get the date from the datepicker, check if it's 18 years ago. — Steve, May 19 '16 at 05:47
[This question](http://stackoverflow.com/questions/4060004/calculate-age-in-javascript) will help you to find age given a `Date` object. — 4castle, May 19 '16 at 05:55
Have you referred to a tutorial? I suggest you do that for datepicker before asking here. — cst1992, May 19 '16 at 06:24

Try this:

Jquery:

$('#datepicker').datepicker({
onSelect: function(value, ui) {
    var today = new Date(), 
        age = today.getFullYear() - ui.selectedYear;
    if(age >= 18)
        $('#age').text("User is 18 years old");
    else
        $('#age').text("User is 18 not years old");
},
maxDate: '+0d',
changeMonth: true,
changeYear: true,
yearRange: '-110:-30'

});

Html:

<input type="text" id="datepicker" />
<div id="age" />

What if they turn 18 later that year? This would say they are 18 when they were actually 17. – 4castle May 19 '16 at 05:53
@kirangadhvi but he told to use datepicker – Jayesh Chitroda May 19 '16 at 05:57
@kirangadhvi That has the same problem. It assumes they've had their birthday already this year. – 4castle May 19 '16 at 05:57
@4castle i am not getting your point friend "What if they turn 18 later that year? " – Jayesh Chitroda May 19 '16 at 05:58
Say I was born December 31st, 2000. If today was January 1st, 2018. It would say I was 18, even though I'm actually 17, but I'll turn 18 later that year. – 4castle May 19 '16 at 06:00
