我如何验证某人从出生之日起已超过18岁? [英] How can I validate that someone is over 18 from their date of birth?

问题描述

我正在验证驾驶员的出生日期，从当前日期开始至少应为18.

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 %>');   
var Split = Dates.value.split("/");

if (parseInt(Split[2]) > 1993) 
{
    alert("DOB year should be less than 1993");
    Dates.focus();
    return false;
}  

我正在使用上面的JavaScript验证来检查一个人的18岁以上的DOB，但这是不正确的.我需要检查今天的日期，并且应该在18岁以上.如何比较和检查当前日期?

I am using this above JavaScript validation for checking a person's DOB above 18, but it is not correct. I need to check with today's date and it should be above 18. How can I compare and check with the current date?

推荐答案

我认为更好的选择是计算用户年龄，并在if语句中使用该年龄.

I think a better alternative would be to calculate the age of the user, and use that in your if statement.

有关此操作的信息，请参见以下SO答案:
