Question

我想将存储在我服务器上的营业时间与当前时间进行比较。

鉴于以下内容：

开始：09.00 结束：00.30

如果商店已开启或关闭，我想要结果。当当前时间不在给定的开始和结束时间时，商店关闭。

我到目前为止使用的代码不起作用。我收到错误：

TypeError：无法读取属性＆＃39; 3＆＃39;未定义的

firebase.database().ref("v3/standalonelist/bars").on('value', function(snapshot) {

    $timeout(function() {
      $scope.content = snapshot.val();
      snapshot.forEach(function(childSnapshot) {

        $scope.data1 = [childSnapshot.val()];
        $scope.locations1 = $scope.data1

        $scope.locations1.forEach(function(item) {

        $scope.getMinutes = function(str) {
                var time = str.split('.');
                return time[0] * 60 + time[1] * 1;
              }
              $scope.getMinutesNow = function() {
                var timeNow = new Date();
                return timeNow.getHours() * 60 + timeNow.getMinutes();
              }
              var a = new Date();
              var day = a.getDay(); // 3
              var now = $scope.getMinutesNow();
              console.log(item.opens[day]); // returns 09.00

              if (start > end) {
                end += $scope.getMinutes('24.00');

                })

              } else {
                $scope.open = false; // Store is closed
              }
         })
       })

我认为你让它变得有点复杂......

all_from

这是一个工作小提琴：http://jsfiddle.net/L770r2qk/

您可能还想考虑不同的日子，例如从深夜到凌晨运营的商家。为此，您还需要使用def all_from(datab,university): # Create flag to see if there are results result = False for k in datab.keys(): # Knowing that university will always be in the same column if university == datab[k][2]: result = True print datab[k] if not result: print 'Nobody goes to University there!' datab = dict() datab[1] = ['walker','matthew','uuc',1] datab[2] = ['stewart','rory','uum',2] datab[3] = ['toner','kevin','qub',4] datab[4] = ['hughes','johnny','uuj',1] datab[5] = ['douglas','kenny','uuc', 3] datab[6] = ['hooks', 'peter','qub',1] datab[7] = ['campbell','vicky','uuj',2] datab[8] = ['crooks','laura','uum',4] datab[9] = ['irwin','emma','uuc',3] datab[10] = ['patterson','steve','uuc',1] university = (raw_input('Enter the University here: ')) all_from(datab,university)和var today = new Date(), open = "Open", closed = "Closed", display = document.getElementById('display'), start = new Date(), end = new Date(); // Set the opening hour:minutes start.setHours(10); start.setMinutes(5); // Set the closing hour:minutes end.setHours(18); end.setMinutes(30); // Check the time based on milliseconds if ( today.getTime() >= start.getTime() && today.getTime() < end.getTime() ) { display.innerHTML = open; } else { display.innerHTML = closed; }。然后，您可能还想考虑月份更改，然后使用start.setDate(12)和end.setDate(13)。

这些额外的功能取决于您，我将让您将它们实施到示例中。

如何比较开放时间？
