基于ngTable的ocLazyLoad负载

Question

在我们的一个项目中，我们试图为ngTable库编写一个包装器！在这个组件的控制器中，我们使用ngTable加载ocLazyLoad。以下是我们所写的：

数据栅格组件

(function() {

  'use strict';

  angular
    .module('CommonApplication')
    .component('datagrid', {
      scope: true,
      bindings: {
        basepath: '@',
        title: '@',
        dataset: '<'
      },
      templateUrl: '/frontend/components/global/datagrid/templates/datagrid.html',
      controller: 'DataGridController',
    });

})();

带有$ocLazyLoad的数据集控制器(不工作：~\\)

(function() {

  'use strict';

  angular
    .module('CommonApplication')
    .controller('DataGridController', 
    [ '$scope', '$injector', '$ocLazyLoad', DataGridController ]);

  function DataGridController($scope, $injector, $ocLazyLoad) {

    var vm = this;
    var components = {
      datagrid: [
        'https://unpkg.com/ng-table@2.2.0/bundles/ng-table.min.css',
        'https://unpkg.com/ng-table@2.2.0/bundles/ng-table.min.js'
      ]
    };

    $ocLazyLoad.load(components.datagrid).then(function() {
      var NgTableParams = $injector.get('NgTableParams');
      vm.data = [{name: "Moroni", age: 50},{name: "Moroni", age: 50},{name: "Moroni", age: 50},{name: "Moroni", age: 50}];
      vm.tableParams = new NgTableParams({
        page: 1,
        count: 10
      }, {
        dataset: vm.data
      });
    });
  }

})();

无$ocLazyLoad的数据农业控制器(Works)

(function() {

  'use strict';

  angular
    .module('CommonApplication')
    .controller('DataGridController', 
    [ '$scope', '$injector', '$ocLazyLoad', DataGridController ]);

  function DataGridController($scope, $injector, $ocLazyLoad) {

    var vm = this;
    var components = {
      datagrid: [
        'https://unpkg.com/ng-table@2.2.0/bundles/ng-table.min.css',
        'https://unpkg.com/ng-table@2.2.0/bundles/ng-table.min.js'
      ]
    };

    var NgTableParams = $injector.get('NgTableParams');
    vm.data = [{name: "Moroni", age: 50},{name: "Moroni", age: 50},{name: "Moroni", age: 50},{name: "Moroni", age: 50}];
    vm.tableParams = new NgTableParams({
      page: 1,
      count: 10
    }, {
      dataset: vm.data
    });
  }

})();

使用ocLazyLoad时，如果我在定义vm.tableParams的行上设置了一个断点，当它被new NgTableParams填充时，它的设置和其他属性在它们的arguments属性中有这个特殊的错误。

下面是指向$ocLazyLoad.then函数回调结束的异常错误！这是datagrid.js:47:7，因为我们将这些js文件和另一个js文件连接到datagrid.js中

TypeError: 'caller' and 'arguments' are restricted function properties and cannot be accessed in this context.

对此有什么想法吗？！

显然，懒散的加载，即使使用它的承诺.then(callback)不使角等待它的完成！

我所做的是在加载ngTableParams完成时使用ng-table初始化一个表！考虑到这一点，我决定使用一个简单的技巧！

我将ngTableParams附加到一个名为vm.tableParams的作用域变量，稍后我将使用它在使用ng-table的指令时正确地初始化视图中的表。

视图: datagrid.pug

// Load Directive if Params in the controller were attached to the scope!
.row.expanded(ng-if="table.tableParams")
    .small-12.columns 
      table.data-table.hover.stacktable.table-condensed.table-bordered.table-striped(ng-table-dynamic="table.tableParams with table.headers",template-pagination="custom/pager", show-filter="true")
        tr(ng-repeat="(rowIndex, row) in $data ")
          td(ng-repeat="column in $columns", ng-switch="column.field")
            input.selectSwitch( ng-switch-when="selector", type="checkbox", ng-model="table.checkboxes.items[row.id]") 
            div(ng-switch-when="id") {{ rowIndex + 1 }}
            div(ng-switch-when="body") {{ row }}
            span(ng-switch-default) {{row[column.field]}}

控制器: datagrid.controller.js

// Lazyload datagrid components and Initialize headers and parametres!
    $ocLazyLoad.load(components.datagrid).then(function (){
      self.headers = self.dataset.headers;
      self.dataset.headers.forEach(function( header ) {
        header.title = header.headerTitle;
      });
      var NgTableParams = $injector.get('NgTableParams');
      self.tableParams = new NgTableParams({
        count: 5
      }, {
        dataset: self.dataset.data
      });
    });

这样，我们就不会手动使用$compile重新呈现视图，而让角处理编译本身，而不影响性能:)
