Question

您好我正在制作一个简单的jquery函数，可以跟踪它的时间，并通过更改div的显示属性来显示商店是打开还是关闭。

但我也需要加入会议记录，因为该商店例如在7:30开放。如何使用分钟数来使其工作？

我认为它会像：＆amp;＆amp;小时+分钟＆lt; = 11.30＆amp;＆amp;小时＆lt; = 18.00）？但这不起作用。任何帮助表示赞赏

 var now = new Date();
    var weekday = new Array(7);
    weekday[0] = "Monday";
    weekday[1] = "Tuesday";
    weekday[2] = "Wednesday";
    weekday[3] = "Thursday";
    weekday[4] = "Friday";
    weekday[5] = "Saturday";
    weekday[6] = "Sunday";

    var checkTime = function() {
      var dayOfWeek = now.getDay();
      var hour = now.getHours();
      var minutes = now.getMinutes();



      if (( dayOfWeek == 6)) {
        $('.opening-js').css('display', 'none');
        $('.availability-status-closed').css('display', 'block');
      } 

    else if ((dayOfWeek == 0 || dayOfWeek == 1 || dayOfWeek == 2 || dayOfWeek == 3) && hour <= 11 && hour <= 18.00) {
         $('.opening-js').css('display', 'none');
         $('.availability-status-closed').css('display', 'block');
      } 

     else if ((dayOfWeek == 0 || dayOfWeek == 1 || dayOfWeek == 2 || dayOfWeek == 3) && hour >= 11 && hour <= 18.00) {
         $('.opening-js').css('display', 'block');
         $('.availability-status-closed').css('display', 'none');
      } 

      else {
        if ((dayOfWeek == 5) && hour >= 10.00 && hour <= 16.00) {
          $('.availability-status-open').css("display", "block");
          $('.availability-status-closed').css("display", "none");
        }
      }
    };
    setInterval(checkTime, 1000);
    checkTime();

Answer 1

代码中的hour和minutes都是整数

var hour = now.getHours();
var minutes = now.getMinutes();

所以你需要使用两个变量

if((hour == 7 && minutes>=30) || hour>7){
   // it is 7:30 or later.
}

或者，您可以将其降低到最低公分母...... totalMinutes

var totalMinutes = (now.getHours()*60) + now.getMinutes();
var sevenThirty = (7*60)+30;
if(totalMinutes >= sevenThirty){
    // it is 7:30 or later
}

Answer 2

如果您想将时间作为字符串进行比较，请首先尝试将小时和分钟转换为单个字符串。

例如

var now = new Date();
var hours = now.getHours().toString().length > 1 ? now.getHours() : "0" + now.getHours();
var minutes = now.getMinutes().toString().length > 1 ? now.getMinutes() : "0" + now.getMinutes();

var time = hours + "." + minutes;

console.log(time);

另一个选项是仅比较Date个对象。

var time1130 = new Date();
time1130.setHours(11);
time1130.setMinutes(30);

console.log(now > time1130);

或者比较整数（这可能是最简单的方法），正如Jamiec回答中提到的那样

Jquery / js具体时间与分钟
