从后端获取数据时,分页控件未显示在ng-table中

Question

我从后端获取数据列表并使用ng-table显示它.问题是它没有显示分页控件.以前,当我使用虚拟数据显示ng-table时,分页工作完全正常.有人可以帮帮我吗？

这是我的HTML:

<table ng-table="tableParams" show-filter="true" class="table">
            <thead>
                    <tr>
                            <th ng-repeat="column in columns" ng-show="column.visible"
                                    class="text-center" ng-class="{
                                    'sort-asc': tableParams.isSortBy(column.field, 'asc'),
                                    'sort-desc': tableParams.isSortBy(column.field, 'desc'),
                                    'sortable': !$first
                                    }"
                                    ng-click="tableParams.sorting(column.field, tableParams.isSortBy(column.field, 'asc') ? 'desc' : 'asc')">
                                    <div>{{column.title}}</div>
                            </th>
                    </tr>

            </thead>
            <tr ng-repeat="user in data | filter:searchText">

                    <td width="30" style="text-align: left">
                            <input type="checkbox" ng-model="checkboxes.items[user.id]" />
                    </td>

                    <td data-title="'Email Id'" class="text-center" sortable="email" ng-show="columns[1].visible">
                            <span>{{user.email}}</span>
                    </td>
                    <td data-title="'User Karma'" class="text-center" sortable="userkarma" ng-show="columns[2].visible">
                            <span>{{user.userkarma}}</span>
                    </td>
                    <td data-title="'Date Joined'" class="text-center" sortable="datejoined" ng-show="columns[3].visible">
                            <span>{{user.datejoined}}</span>
                    </td>
                    <td data-title="'Unsubscribed'" class="text-center" sortable="status" ng-show="columns[4].visible">
                            <span>{{user.unsubscribed}}</span>
                    </td>
            </tr>
        </table>

以下是我的js文件:

for (var i = 0; i < UserList.getUsers()
            .length; i++) {
            $scope.data.push({
                id: UserList.getUsers()[i]._id,
                email: UserList.getUsers()[i].email,
                userkarma: UserList.getUsers()[i].healthScore,
                datejoined: moment(UserList.getUsers()[i].firstSessionAt)
                    .format("MMMM Do YYYY"),
                unsubscribed: UserList.getUsers()[i].unsubscribed
            })
        };
        $scope.columns = [{
                title: '',
                field: 'checkbox',
                visible: true
            },
            {
                title: 'Email',
                field: 'email',
                visible: true
            }, {
                title: 'User Karma',
                field: 'userkarma',
                visible: true
            }, {
                title: 'Date Joined',
                field: 'datejoined',
                visible: true
            }, {
                title: 'Unsubscribed',
                field: 'unsubscribed',
                visible: true
            }
        ];

        $scope.tableParams = new ngTableParams({
            page: 1, 
                count: 10, // count per page
                filter: {
                    name: 'M' // initial filter
                },
                sorting: {
                    name: 'asc'
                }
            }, {
                total: $scope.data.length, // length of data
                getData: function ($defer, params) {
                    // use build-in angular filter
                    var filteredData = params.filter() ?
                        $filter('filter')($scope.data, params
                            .filter()) :
                        data;
                    var orderedData = params.sorting() ?
                        $filter('orderBy')($scope.data,
                            params.orderBy()) :
                        $scope.data;
                    params.total(orderedData.length); // set total for recalc paginationemail

                    $defer.resolve(orderedData.slice((
                            params.page() -
                            1) * params.count(),
                        params.page() *
                        params.count()));
                }
            });

发生这种情况是因为在$scope.tableParams.reload()异步数据加载后用于刷新数据的常用函数不刷新表中的总项数.它之前没有发生过,因为当您使用虚拟数据时,在开头正确设置了此值.

您需要添加params.total(data.length);的getData功能,手动刷新值.
