How can I validate that someone is over 18 from their date of birth?

Question

I am doing validation for Driver\'s Date of birth, it should be minimum of 18 from the current date.

var Dates = $get(\'<%=ui_txtDOB.ClientID %>\');            


        

Answer 1

let TODAY = new Date(Date.now());
let EIGHTEEN_YEARS_BACK = new Date(new Date(TODAY).getDate() + "/" + new Date(TODAY).getMonth() + "/" + (new Date(TODAY).getFullYear() - 18));
let USER_INPUT = new Date("2003/12/13");
// Validate Now
let result = EIGHTEEN_YEARS_BACK > USER_INPUT // true if over 18, false if less than 18

I think this is the closest possible way to check.
