Angular 数据表不处理数据

Question

我正在使用 Angular-datatable 来显示数据并且它可以很好地处理静态数据，但是当动态提供数据时它不起作用。这让我很难过。

What i want to achieve is to load data from ajax in datatable.

我正在使用以下代码进行初始化，它工作正常Plunker：

function MyChapterController($scope, $q, DTOptionsBuilder, DTColumnBuilder, chapter) {
    var vm = this;     

    vm.dtOptions = DTOptionsBuilder.newOptions()
        .withPaginationType('full_numbers')
        .withDisplayLength(2)
        .withDOM('pitrfl');
    vm.dtColumns = [
        DTColumnBuilder.newColumn('id').withTitle('ID'),
        DTColumnBuilder.newColumn('title').withTitle('First name'),
        DTColumnBuilder.newColumn('lastName').withTitle('Last name').notVisible()
    ];

    vm.myChapters = [];
}

以下代码无效检查 Plunker:

function MyChapterController($scope, $q, $resource, DTOptionsBuilder, DTColumnBuilder, chapter) {
    var vm = this;     

    vm.dtOptions = DTOptionsBuilder.newOptions()
        .withPaginationType('full_numbers')
        .withDisplayLength(2)
        .withDOM('pitrfl');
    vm.dtColumns = [
        DTColumnBuilder.newColumn('id').withTitle('ID'),
        DTColumnBuilder.newColumn('title').withTitle('First name'),
        DTColumnBuilder.newColumn('lastName').withTitle('Last name').notVisible()
    ];

    vm.myChapters = [{
          "id": 860,
          "firstName": "Superman",
          "lastName": "Yoda"
      }, {
          "id": 870,
          "firstName": "Foo",
          "lastName": "Whateveryournameis"
      }, {
          "id": 590,
          "firstName": "Toto",
          "lastName": "Titi"
      }, {
          "id": 803,
          "firstName": "Luke",
          "lastName": "Kyle"
      }];

}

我也尝试过 dataresource Plunker 但这里也很不幸。

它已经消耗了我很多时间。所以最后我决定听取大家的建议。任何帮助，将不胜感激。

你错过了两点：

控制器未被调用，因为它未添加到标记中。如果您以后要使用 ui-router 没关系，因为您可以在配置中添加控制器。
您的 table 未填充，因为您错过了添加绑定，例如{{chapter.id}} 和 myChapters 在 $scope 中不可用，因为您使用的是 controllerAs 语法。

请查看下面或更新后的 plunkr 中的演示。

在下面的演示中，我只将 $http.get(...) 更改为 $http.jsonp(...) 以从 mocky.io.

获取 json 数据

更新

要使过滤器成为分页功能，您必须将 table 标记更改为此。

<table datatable="ng" dt-options="chapterCtrl.dtOptions" dt-column-defs="chapterCtrl.dtColumnDefs" id="cb-mychapter-table" class="row-border hover table table-bordered cb-data-table" cellspacing="0" width="100%">

// Code goes here
'use strict';

angular.module('myApp', ['datatables','ngResource']);

(function (angular) {
    'use strict';

    angular
            .module('myApp')
            .controller('myChapterController', MyChapterController)
            .factory('chapter', ChapterFactory);

    MyChapterController.$inject = ['$scope', '$q', '$resource', 'DTOptionsBuilder', 'DTColumnBuilder', 'chapter'];

    function MyChapterController($scope, $q, $resource, DTOptionsBuilder, DTColumnBuilder, chapter) {
        var vm = this;     
        
        vm.dtOptions = DTOptionsBuilder.newOptions()
            .withPaginationType('full_numbers')
            .withDisplayLength(2)
            .withDOM('pitrfl');
        vm.dtColumns = [
            DTColumnBuilder.newColumn('id').withTitle('ID'),
            DTColumnBuilder.newColumn('title').withTitle('First name'),
            DTColumnBuilder.newColumn('lastName').withTitle('Last name').notVisible()
        ];
        
        /*vm.myChapters = [{
              "id": 860,
              "firstName": "Superman",
              "lastName": "Yoda"
          }, {
              "id": 870,
              "firstName": "Foo",
              "lastName": "Whateveryournameis"
          }, {
              "id": 590,
              "firstName": "Toto",
              "lastName": "Titi"
          }, {
              "id": 803,
              "firstName": "Luke",
              "lastName": "Kyle"
          }];*/
        
        chapter.getChapters().then(function(chapters) {
          vm.myChapters = chapters;
        });
    }
    
  ChapterFactory.$inject = ["$http"];
  
  function ChapterFactory($http) {
   return {
     getChapters: function() {
       return $http.jsonp('http://www.mocky.io/v2/55f2b4cb0938f5cd069cff10?callback=JSON_CALLBACK').then(function(response) {
         console.log(response);
         return response.data;
       });
     }
   };
  }
  
}(angular));
