javascript - 我在哪里可以更改此倒计时功能中的日期？

Question

我刚刚下载了这个倒计时脚本（JavaScript），但我不知道如何更改计时器倒计时的日期。原始脚本：

$(function(){
var now = new Date();
// comment out the line below and change the date of your countdown here
var in30Days = new Date( now.getTime() + (30 * 24 * 60 * 60 * 1000) );
// year to countdown to
var countdownYear = in30Days.getFullYear();
// month to countdown to 0 = Jan, 1 = Feb, etc
var countdownMonth = in30Days.getMonth();
// day to countdown to
var countdownDay = in30Days.getDate();

var countdownDate = new Date( countdownYear, countdownMonth, countdownDay );

setupCountdownTimer( countdownDate );

spaceParallax();

hideIphoneBar();

$("[placeholder]").togglePlaceholder();

setupSignupForm();
});

Answer 1

也许 countdownDate... 默认情况下它是用 now + 30 天构建的？你可以改变这个。

重要的部分是：

setupCountdownTimer( countdownDate );

spaceParallax();

hideIphoneBar();

$("[placeholder]").togglePlaceholder();

setupSignupForm();
});

Answer 2

您的代码本身告诉如何做到这一点：

// comment out the line below and change the date of your countdown here
var in30Days = new Date( now.getTime() + (30 * 24 * 60 * 60 * 1000) );
// year to countdown to
var countdownYear = in30Days.getFullYear();
// month to countdown to 0 = Jan, 1 = Feb, etc
var countdownMonth = in30Days.getMonth();
// day to countdown to
var countdownDay = in30Days.getDate();

以下行创建 countDownDate，将年、月和日传递给函数

var countdownDate = new Date( countdownYear, countdownMonth, countdownDay );

setupCountdownTimer( countdownDate );
