减去时间= NAN

Question

我正在尝试创建一个时差功能.我需要能够判断CookieTime是否被粘贴.我尝试过很多不同的东西,似乎无法让它发挥作用.为什么这不会减去任何建议？

我昨晚在帮助下成功完成了DateDiff:Javascript DateDiff

我的控制台中的错误是:未捕获TypeError:对象12:34:00没有方法'getTime'不知道我是否理解这意味着什么.

CookieTime = "12:34:00"; //Cookie time...
currTime   = "05:11:55"; //Current Real Time...

function past(){

//Print the results for testing...
document.write(CookieTime + '<br>'); // = 12:34:00
document.write(currTime + '<br/>');  // = 05:11:55

// = Testing the results here = NaN
document.write(CookieTime.getTime() - currTime.getTime() + '<br/>');

    if (CookieTime - currTime >= 0){
      // Time has pasted!!
      return true;
    } else {
      // Time is not here yet!!
      return false;
    }
}

document.write(past()); //Print response.

您需要解析原始日期:

CookieTime = new Date('1970-1-1 12:34:00'); //Cookie time...
currTime   = new Date('1970-1-1 05:11:55'); //Current Real Time...
