我想设置一个倒计时器在 24 小时后结束。这是迄今为止我用于计时器的代码:

countdown: {
    // Possible options are 'default' or 'piechart'
    type: 'default',
    // The date when the countdown started. Used by the progress bars. 24 Hour format (00 to 23): Month Day, Year Hours:Minutes
    startDate: new Date(),
    // The target date we're counting down to. 24 Hour format (00 to 23): Month Day, Year Hours:Minutes
    targetDate: new Date("startDate"+1)
},

最初，模板附带的代码是；

countdown: {
    // Possible options are 'default' or 'piechart'
    type: 'default',
    // The date when the countdown started. Used by the progress bars. 24 Hour format (00 to 23): Month Day, Year Hours:Minutes
    startDate: new Date("November 1, 2013 00:00"),
    // The target date we're counting down to. 24 Hour format (00 to 23): Month Day, Year Hours:Minutes
    targetDate: new Date("July 20, 2014 11:13")
},

我希望倒计时每天开始并在 24 小时后结束，这就是我删除开始日期的原因。任何帮助，将不胜感激。谢谢。

Answer 1

var startDate = new Date();
var endDate = new Date();
endDate.setDate(startDate.getDate() + 1);

var countdown = { startDate: startDate, targetDate: endDate };
