Moment/Jquery-一个简单时间线的愚蠢问题

我得到了这个社区的很多帮助，让我的时间线报告正常工作。设置方式是通过检查ajax返回来获取日期范围。然后它会把我所有的参赛作品按星期几分组。如果在该日期范围内没有特定的条目，那么它只会返回"今天没有条目"

到目前为止，一切都在工作，你可以看到下面的例子：https://jsfiddle.net/j3yg2j7j/7/

然而，我注意到，如果日期范围中的最后一天为空，它会忽略它。我需要它返回"今天没有条目"。即使最后一天是空的。

这是一个问题的例子。https://jsfiddle.net/j3yg2j7j/6/

更新：发现另一个奇怪的问题。当我给它的范围从2016-05-02到2016-05-05。我开始收到重复的项目。

这是Ajax请求：

responseText: {
    d: {
        results: [{
            ID: "1",
            Description: "Test1",
            Date: "2016-05-02 09:45"
        }, {
            ID: "2",
            Description: "Test2",
            Date: "2016-05-02 10:45"
        }, {
            ID: "3",
            Description: "Test3",
            Date: "2016-05-03 11:45"
        }, {
            ID: "4",
            Description: "Test4",
            Date: "2016-05-03 11:45",
        }]
    }
}

这是javascript：

      var items_by_date  = {}; // declare an object that will have date indexes
      $.ajax({url:"/SomeUrlBeginninWithSlash",
          dataType: 'json',
          cache: false,
          success: function (data) {
                    console.log("SUCCESS",data);    
                    drawTable(data.d.results);
          }
      });
 var drawTable = function(data) {
  // First sort the entries by date:
  data = data.sort(function(a, b) {
    return (moment(a.Date) - moment(b.Date));
  });
  // Find the date range to work with by looking at each end of the array:
  var firstDate = moment("2016-05-02");
  var lastDate = moment("2016-05-04");
  // loop through each day in that range, keeping track of a starting point i
  // so we don't have to keep checking already-passed events.
  var i = 0, // pointer to the first entry to check on the next date
    ret = ""; 
  for (var thisDate = firstDate; thisDate <= lastDate; thisDate.add(1, 'days')) {
    ret += '<tr><th>' + thisDate.format("dddd, MMMM D") + "</th></tr>";
    // check to see if the next entry is already beyond thisDate:
    if (moment(data[i].Date) > thisDate.endOf('day')) {
      ret += "<tr><td>No entries today.</td></tr>";
    } else {
      // starting at entry i, display all entries before the end of thisDate:
      for (var j = i; j < data.length; j++) {
        if (moment(data[j].Date) < thisDate.endOf('day')) {
          // the next one belongs on thisDate, so display it:
          ret += '<tr><td>' + moment(data[j].Date).format("HH:mm") + " - " + data[j].Description + "</td></tr>";
        } else {
          // next one is not for thisDate, so we can go on to the next day.
          i = j; // It'll start here, so we don't waste time looping over past events
          break; // (out of the inner loop)
        }
      }
    }
  }
  $('#x').html(ret);
}

我知道我忽略了一些简单的事情，但我无法完全理解。
