AngularJS orderBy 不适用于自定义函数

Question

目前，我已经创建了自定义函数以从 Moment 中找到 fromNow，我想根据函数返回的值对数据进行排序。

我想将 Table 元素放在顶部，从现在开始的天数 较短

在下面的 table 31 Days From Today 中，第 2 列较小，我想将此元素放在顶部，我尝试了以下方法但是没用

谁能帮帮我 Table

AngularJS 排序方式

<tr ng-repeat="x in Holidays|orderBy:findFromNow">
                <td>{{$index+1}}</td>
                <td>{{x.Day}}</td>
                <td>
                <span class="label label-warning">{{findFromNow(x.Date)}} Days From Today</span></td>
                </tr>

函数

$scope.findFromNow = function (inputDate) {
        var m = moment(inputDate, "D-MMM-YY");
        var today = moment().startOf('day');
        var days = Math.round((today - m) / 86400000);
        if (days > 0) {
            return 999;
        } else {
            return (days * (-1));
        }

    }

节假日JSON

  [
    {
      "Day": "Monday",
      "Date": "2-Jan-17"
    },
    {
      "Day": "Monday",
      "Date": "20-Feb-17"
    },
    {
      "Day": "Monday",
      "Date": "29-May-17"
    },
    {
      "Day": "Monday",
      "Date": "3-Jul-17"
    },
    {
      "Day": "Tuesday",
      "Date": "4-Jul-17"
    },
    {
      "Day": "Monday",
      "Date": "4-Sep-17"
    },
    {
      "Day": "Thursday",
      "Date": "23-Nov-17"
    },
    {
      "Day": "Friday",
      "Date": "24-Nov-17"
    },
    {
      "Day": "Monday",
      "Date": "25-Dec-17"
    }
  ]

您应该在使用前编写单独的函数或检查 inputDate 的类型，因为在 orderBy 中，inputDate 是 Object 而不是 Date

 $scope.sortDate = function(inputDate){
    var m = moment(inputDate.Date, "D-MMM-YY");
    var today = moment().startOf('day');
    var days = Math.round((today - m) / 86400000);
    if (days > 0) {
        return 999;
    } else {
        return (days * (-1));
    }

}
