Question

我正在尝试将过滤器应用于我的数据表。

        <div class="widget-content  table-container" ng-controller="getEmployeesController" style="overflow:auto">

            <table ng-table="employeesList" show-filter="true" class="table table-striped table-bordered">
                <tr ng-repeat="employee in $data">
                    <td data-title="'#'">
                        {{ (itemsPerPage * (pageNumber-1)) + $index+1 }}
                    </td>
                    <td data-title="'Name'" sortable="'Name'" filter="{ 'firstName+lastName': 'text' }">
                        {{employee.firstName +""+employee.lastName}}
                    </td>
                    <td data-title="'First Name'" sortable="'firstName'" filter="{ 'firstName': 'text' }">
                        {{employee.firstName}}
                    </td>
                    <td data-title="'Last Name'" sortable="'lastName'" filter="{ 'lastName': 'text' }">
                        {{employee.lastName}}
                    </td>
                </tr>
            </table>
        </div>

第2和第3次过滤效果很好。我想要一个TD，其中第一个名称和第二个名称连接在一起。

App.js

//Datatable
myApp.factory('dataTable', ['$filter', 'ngTableParams', '$rootScope', function ($filter, ngTableParams, $rootScope) {

    var factoryDefinition = {
      render: function($scope, config, componentId, data) {
          if (!config) config = { filter: { 'firstName': $rootScope.mysearch } };

        var config = angular.extend({}, {page:1, count:10}, config)

        $scope[componentId] = new ngTableParams(config, {
            total: data.length, // length of data
            getData: function ($defer, params) {
                // organize filter as $filter understand it (graph object)
                var filters = {};
                var val = $rootScope.mysearch;
                var key = "firstname";
                $rootScope.mysearch = "";

                angular.forEach(params.filter(), function (val, key) {
                    var filter = filters;

                    for (var i = 0; i < parts.length; i++) {

                            filter = filter[parts[i]];
                        }
                        else {
                            filter[parts[i]] = val;
                        }
                    }

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

                $scope.itemsPerPage = params.count();

控制器

myApp.controller('getEmployeesController', ['$scope', 'employeeServices', 'dataTable', '$window', '$timeout', '$filter', '$rootScope', 'ngDialog',
    function ($scope, employeeServices, dataTable, $window, $timeout, $filter, $rootScope, ngDialog) {
    employeeServices.getEmployees().then(function (result) {
        $scope.data = result.data;
    });

连锁的TD未正确过滤。我该怎么做才能使它发挥作用？

找到解决方案，

在集合中创建一个新属性，然后将其设置为连接对象以解决问题。 控制器：

myApp.controller('getEmployeesController', ['$scope', 'employeeServices', 'dataTable', '$window', '$timeout', '$filter', '$rootScope', 'ngDialog',
    function ($scope, employeeServices, dataTable, $window, $timeout, $filter, $rootScope, ngDialog) {
    employeeServices.getEmployees().then(function (result) {
        $scope.data = result.data;
        angular.forEach(result.data, function (value, key) {
            if (value.lastName == undefined) {

            }
            var fullName = value.firstName + '' + ((value.lastName != undefined) ? (value.lastName) : (''));
            result.data[key].fullName = fullName;

        });
  });

<强> HTML ：

<td data-title="'Name'" sortable="'firstName'" filter="{ 'fullName': 'text' }" style="width:100px">
                                {{employee.fullName}}
                            </td>
