如何让多个jQuery / datetimepicker指令一起工作?

虽然我在Angular指令中创建了以下jQuery datetimepicker插件,但该工作正常:

我当然希望能够在页面上多次调用此指令,但即使我将id设为变量,多个控件也因某些原因无法工作,我怀疑它是因为我需要使dp.change参数值动态化,但我不确定它究竟是指什么。

如何让该指令在页面上多次独立工作?

<script type="text/ng-template" id="templateCalendarPicker">
    <div class='input-group date datepicker_format' id="{{dpid}}" style="width:{{width}}px">
        <input type='text' class="form-control" />
        <span class="input-group-addon">
            <span class="glyphicon glyphicon-calendar"></span>
        </span>
    </div>  
</script>

<div ng-controller="mainController">
    <div calendar-picker width="200" date="date1" dpid="d1"></div>
    <div>The first date is <b>{{date1}}</b>.</div>
</div>

<div ng-controller="mainController">
    <div calendar-picker width="200" date="date2" dpid="d2"></div>
    <div>The second date is <b>{{date2}}</b>.</div>
</div>
angular.module('myApp', [])
.controller('mainController', function($scope) {
    $scope.date1 = '2015-09-01';
    $scope.date2 = '2015-09-30';
})
.directive('calendarPicker', function() {
    var controller = function ($scope) {
        var vm = this;
        $('#datepicker').datetimepicker({
            format:'YYYY-MM-DD',
            defaultDate: new Date($scope.date)
        });

        var elemId = '#'+$scope.dpid;
        console.log(elemId);

        $(document).on('dp.change', elemId, function (a) {
            var selected_date = moment(a.date._d).format('YYYY-MM-DD');
            $scope.date = selected_date;
            $scope.$apply();
        });

        $scope.$on('$destroy', function() {
            $('#datepicker').data("DateTimePicker").destroy();
        });        
    };

    return {
        restrict: 'A',
        scope: {
            date : '=',
            width : '@',
            dpid : '@'
        },
        controller: controller,
        controllerAs: 'vm',
        bindToController: true,
        templateUrl: 'templateCalendarPicker'
    };
});

<div class="form-group" show-errors>
  <div class="input-group date">
         <div class="input-group-content">
           <input type="text" datefield name="StartDate" class="form-control" ng-model="startDate" readonly="readonly" style="cursor:pointer;" required>
    </div>
    <span class="input-group-addon"><i class="fa fa-calendar"></i></span>
  </div>
</div>
  

您可以重复使用我使用的 datefield 指令。

Angular Code

angular.module('ngApp').directive('datefield', function () {
        return {
            restrict: 'AC',
            link: function (scope, element, attrs) {
                element.datepicker({ autoclose: true, todayHighlight: true });
            }
        }
    });

此外,你不必重复两次mainController,你可以将它封装到一个并带来相同的行为,我用指令装饰任意次。
