javascript - 如何检查时间是否大于javascript中两个日期之间的总时间？

Question

我想检查时间 12.55(这是那里的格式，我无权编辑格式)是否大于 2 个日期之间的总时间，例如 2015-10-12 10:00"和 2015- 10-12 12:00。我已经完成了查找 diff 的第一部分，但不知道如何执行第二部分，即查找时间大于时差。希望有人可以帮助我!

var getDayTimeDiff = function(start, end){

    var date1 = new Date(start);
    var date2 = new Date(end);

    var diff = date2.getTime() - date1.getTime();

    var msec = diff;
    var hh = Math.floor(msec / 1000 / 60 / 60);
    msec -= hh * 1000 * 60 * 60;
    var mm = Math.floor(msec / 1000 / 60);
    msec -= mm * 1000 * 60;
    var ss = Math.floor(msec / 1000);
    msec -= ss * 1000;

    return diff;
}



var timeDiff = getDayTimeDiff("2015-10-12 10:00","2015-10-12 12:00");
console.log(timeDiff); // 7200000


var time2Calc = "12.55";

您可以将时间转换为毫秒，然后比较以毫秒为单位的差异

var getDayTimeDiff = function(start, end) {
  var date1 = new Date(start);
  var date2 = new Date(end);
  return date2.getTime() - date1.getTime();
}

var toMillis = function(time) {
  var parts = time.split('.');
  return (parts[0] * 60 + +parts[1]) * 60 * 1000;
}



function test(t1, t2) {
  var timeDiff = getDayTimeDiff(t1, t2);


  var time2Calc = "12.55";
  var base = toMillis(time2Calc);

  var result = (Math.abs(timeDiff) > base);
  snippet.log(t1 + ' : ' + t2 + ' -> ' + result);
}

test("2015-10-12 10:00", "2015-10-12 23:00");
test("2015-10-12 10:00", "2015-10-12 12:00");
