IE8：对象不支持此属性或方法（日期函数） [英] IE8: Object Doesn't Support This Property or Method (Date function)

问题描述

我收到的错误只出现在伟大的IE8上，它指向以下函数，特别是行： return（expDate.getTime（）> Date.now（））;

I'm getting an error that only appears on the great IE8, it points to the following function, specifically the line: return (expDate.getTime() > Date.now());

$.validator.addMethod("checkDocExpiry",function(value) {
    var driverLicExp = ($('#drivers-license-expiration').val()) ? $('#drivers-license-expiration').val() : '';
    if (driverLicExp != ''){
        var expDate = new Date(driverLicExp);
        return (expDate.getTime() > Date.now());
    }else{
        return (true);
    }
}, "Your driver's license has expired.");

我不确定是什么原因造成这种情况，我对开发旧版浏览器相当新。这在FF，IE10，Chrome，Safari中运行良好。

I'm not sure what would cause this, I am fairly new to developing for older browsers. This runs fine in FF, IE10, Chrome, Safari.

任何帮助都将不胜感激。

Any help would be much appreciated.

谢谢

推荐答案

看起来 Date.now（）不支持IE8（见下表）：

Looks like Date.now() isn't supported in IE8 (see the table at the bottom):

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/now

new Date（）应该为您提供当前日期的日期对象。

new Date() should get you a date object with the current date.
