iPad上的Javascript年龄计算 [英] Javascript age calculation on IPad

问题描述

在每个常规浏览器上，日期都是按正常方式计算的，例如38岁.

On every regular browser, the date is calculated normally .. like 38 year old.

在iPad上，我收到一个非数字(NaN)错误...但是为什么?

On IPad I get a Not a Number (NaN) error... but why?

function getAge(date) {
    var today = new Date();
    var birthDate = new Date(date);
    var age = today.getFullYear() - birthDate.getFullYear();
    var m = today.getMonth() - birthDate.getMonth();
    if (m < 0 || (m === 0 && today.getDate() < birthDate.getDate())) {
        age--;
    }
    return age;

}

NaN @ iPad，IE8，并且可以在Firefox& Chrome正常工作

NaN @ IPad, IE8 and correct working at Firefox&Chrome

推荐答案

您需要在输入日期字符串上进行以下转换，以使其在iPad/iPhone上正常工作.

You need to do the following transformations on the input date string for it work properly on iPad/iPhone.

function getAge(date) {
    date = date.replace(/-/,"/").replace(/-/,"/"); //substitute - with /
    var today = new Date();
    var birthDate = new Date(date);
    var age = today.getFullYear() - birthDate.getFullYear();
    var m = today.getMonth() - birthDate.getMonth();
    if (m < 0 || (m === 0 && today.getDate() < birthDate.getDate())) {
        age--;
    }
    return age;
}
