angularjs - Angular-Strap 日期选择器的动态放置

Question

我有 Angular 带日期选择器放置字段的问题。
有没有办法动态地使放置属性不与窗口高度重叠。[底部，顶部]。

这是 ng-repeat 中的指令。

我们用这种方法得到的placement 属性是一个空字符串，因为placement 属性没有2 路绑定(bind)。

<div class="time_status_container" 
     ng-right-click="calculatePosition($event)" 
     ng-blur="toggleDatepicker()" 
     tabindex="-1" 
     style="outline:none;">

  <div bs-datepicker
       template="template.html"
       container="body"
       ng-model="start_date"
       data-trigger="manual"
       bs-show="show"
       placement="{{showDatePicker.position}}"
       data-max-date="{{ project.end_date }}">
  </div>

  Show Datepicker
</div>

我用这个指令触发日期选择器。

directives
.directive('ngRightClick', ["$parse", function($parse) {
return function(scope, element, attrs) {
    var fn = $parse(attrs.ngRightClick);
    element.bind('contextmenu', function(event) {
        scope.$apply(function() {
            event.preventDefault();
            fn(scope, {$event:event});
        });
    });
};
}]);

这是应该在哪里动态更改的指令。

directives
.directive('stone', function() {
    return {
        restrict: 'E',
        replace:true,
        templateUrl: 'template.html',
        controller:function($scope){

            $scope.toggleDatepicker = function(type){
                if(type == "start"){
                    $scope.showDatePicker['start'] = true;
                    $scope.showDatePicker['end'] = false;
                }
                else if(type == "end"){
                    $scope.showDatePicker['start'] = false;
                    $scope.showDatePicker['end'] = true;
                }
                else{
                    $scope.showDatePicker['start'] = false;
                    $scope.showDatePicker['end'] = false;
                }

                console.log($scope.showDatePicker)
            };

            $scope.calculatePosition = function(e){
                var mouseTopPosition = e.clientY || e.pageY;
                var lastKnowWindowHeight = $scope.getLastKnownWindowHeight();
                var datePickerStoneHeight = $scope.getDatePickerStoneHeight;
                var position;

                if((mouseTopPosition + datePickerStoneHeight) > lastKnowWindowHeight){
                    position = "top";
                }
                else{
                    position = "bottom";
                }

                $scope.showDatePicker = { start:true,position:position };
            };
        }
    };
});

当然，让 showDatePicker.position 成为一个确定正确值并返回该值的函数。
