在 MVC VIEW 中使用 AngularJS/AJAX 呈现后端数据

Question

所以我对 AngularJS 和 AJAX 很陌生，但是最近我收到了这个任务，我必须使用 AngularJS/AJAX 来查看 MVC 框架。但是在网上浏览了几个链接后，我找不到任何与在 MVC 框架中使用 AngularJS/AJAX 相关的资源。

所以我必须在控制器中执行 CRUD，现在我已经完成并且能够在前端呈现数据，但我不确定如何在 AngularJS/AJAX 中执行前端并呈现我检索到的数据从控制器。有没有我可以关注的网站或链接？非常感谢

    @model IEnumerable<WebApplication4.Models.PDAStatus>

@{
    var result = (List<PDAStatus>)ViewData["MyData"];
}

<div class="row justify-content-center">
    <div class="col-md-12">
        <h2>View Outstanding PDA</h2>

在 MVC VIEW 中使用 AngularJS/AJAX 呈现后端数据

在MVC视图中，使用angularjs呈现背​​景数据，可以参考以下代码：

Index.csthml 页面：

@*Use a table to display the data.*@
<div ng-app="myApp" ng-controller="myCtrl">
    <table class="table">
        <thead>
            <tr>
                <th>
                     Id
                </th>
                <th>
                    Name
                </th>
                <th>
                     SelectedState
                </th>
                <th></th>
            </tr>
        </thead>
        <tbody>
            <tr ng-repeat="x in articles">
                <td>{{ x.id }}</td>
                <td>{{ x.name }}</td>
                <td>{{ x.selectedState }}</td>
                <td>button</td>
            </tr>
        </tbody>
    </table>
</div>

@section Scripts{
     @*add the angularjs reference*@
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>
    <script>
        var app = angular.module('myApp', []);
        app.controller('myCtrl', function ($scope, $http) {
            //call the action method to get all data, then assign the response data to the model.
            $http.get("/Article/GetAllArticles").then(function (response) {
                $scope.articles = response.data;
            }); 
        });  
    </script>
}

文章控制器动作方法：

    public IActionResult GetAllArticles()
    {   //query database to get all article with state.
        var articles = new List<Article>(){
            new Article() { Id = 1, Name = "A", SelectedState = "Open" },
            new Article() { Id = 2, Name = "B", SelectedState = "Scheduled" },
             new Article() { Id = 3, Name = "C", SelectedState = "Closed" },
        };
        return Json(articles);
    }

结果如下：
