使用此更新您的angularjs-dropdown-multiselect.js文件的getFindObj（id）功能..

            function getFindObj(id) {
                var findObj = {};

                if ($scope.settings.externalIdProp === '') {
                    findObj[$scope.settings.idProp] = id;

                } else {
                    findObj[$scope.settings.externalIdProp] = id;
                    angular.forEach($scope.options, function (value, index) {
                        if(value.id == id){
                            findObj.label = value.label;
                        }
                    });
                }

                return findObj;
            }
