Validate date for anyone over 18 with jQuery

Question

I have a form on my site that should validate for anyone who is over 18.

var day = $(\"#dobDay\").val();
var month = $(\"#dobMonth\").val();
var year = $(\"         


        

Answer 1

I think it will be easier to understand if we rename the variables

mydate => givenDate
currdate => thresholdDate

if givenDate > thresholdDate => you are not 18
else => you are 18

i.e.

if ( givenDate > thresholdDate ){
    // you are not 18
}

i.e

if ((givenDate - thresholdDate) > 0){
    // you are not 18
}

i.e.

if ((mydate - currdate ) > 0){
    // you are not 18
}
