javascript - AngularJS ngTable 分页不起作用，在一页上显示所有数据

Question

我正在使用 ngTables 以表格格式加载我的数据并显示分页。我的数据是从 Firebase 数据库加载的，目前长度是 9。所以我想每页显示三行。

下面是我的代码，当我的页面加载时，所有九行都加载在第一页上，而我将计数设置为 3，而且当我点击页面时，它不会继续。

还有一个问题，过滤也不起作用。

这是我在 HTML View 中的 ng-table 没有改变并且:

<div ng-controller="mycontroller">
    <strong>Filter:</strong> {{tableParams.filter()|json}}
        <table ng-table="tableParams" show-filter="true" class="table table-striped">
            <tr ng-repeat="obj in mylist">
                <td data-title="'Department'" filter="{ 'name': 'text' }">{{ obj.department }}</td>
                <td data-title="'Lastname'" >{{ obj.lastname }}</td>
                <td data-title="'City'">{{ obj.city }}</td>
            </tr>
        </table>
</div>

和mycontroller.js:

app.controller('mycontroller', ["$scope", "$filter", "ngTableParams", "DatabaseRef", "$firebaseArray",
    function ($scope, $filter, ngTableParams, DatabaseRef, $firebaseArray) {

        //get all data from firebase database
        var mydb = DatabaseRef.ref("projects").orderByKey();
        $scope.mylist = $firebaseArray(mydb);

        var data = $scope.mylist;
        data.$loaded().then(function(data) {
            console.log(data.length); // data is loaded here, and the length is 9
            $scope.tableParams = new ngTableParams({
                page: 1, // show first page
                count: 3, // count per page
                filter: {
                    name: '' // initial filter
                }
            }, {
                total: data.length, // length of data
                getData: function ($defer, params) {
                    // use build-in angular filter
                    var orderedData = params.filter() ? $filter('filter')(data, params.filter()) : data;
                    $scope.users = orderedData.slice((params.page() - 1) * params.count(), params.page() * params.count());
                    params.total(orderedData.length);
                    // set total for recalc pagination
                    $defer.resolve($scope.users);
                }
            });
        });
    }]);

这是有效的解决方案:

app.controller('mycontroller', ["$scope", "$filter", "ngTableParams", "DatabaseRef", "$firebaseArray",
    function ($scope, $filter, ngTableParams, DatabaseRef, $firebaseArray) {

        //get all data from firebase database
        var mydb = DatabaseRef.ref("projects").orderByKey();
        $scope.mylist = $firebaseArray(mydb);

        var data = $scope.mylist;
        data.$loaded().then(function(data) {
            console.log(data.length); // data is loaded here, and the length is 9
            $scope.tableParams = new ngTableParams({
                page: 1, // show first page
                count: 3, // count per page
                filter: {
                    name: '' // initial filter
                },
                sorting: { city: "asc" }
            }, {
            filterSwitch: true,
            total: 0, //data.length, // length of data
            getData: function ($defer, params) {
                // use build-in angular filter
                var filteredData = params.filter() ?
                    $filter('filter')(data, params.filter()) :
                    $scope.mylist;

                var orderedData = params.sorting() ?
                    $filter('orderBy')(filteredData, params.orderBy()) : filteredData;

                params.total($scope.mylist.length);
                // set total for recalc pagination
                $defer.resolve(orderedData.slice((params.page() - 1) * params.count(), params.page() * params.count()));


                }
            });
        });
    }]);
