AngularJS显示一个json对象

Question

I receive from my rest api news with the specified id. When I display all news I used ng-repeat and works fine but when I want display one object this method is not working.

My .when code:

.when('/displaynews/:id',{
    templateUrl: 'views/display.html',
    controller: 'NewsDisplayController',
    constollerAs: 'displaydash'
})

and the controller :

.controller('NewsDisplayController',
    function($routeParams, NewsModel){

      var displaydash = this;
      var newsId = $routeParams.id;
      path = 'getNewsById/'+newsId;

      function getNewsById() {
          NewsModel.getNewsById().then(function (result){
              displaydash.news = result.data;
              console.log(displaydash.news);
          })
      }

      getNewsById();
})

Result from console.log:

Object { id="56f1ba6b275c8aa5bf4895d8",  title="Tytul",  text="Text",  more...}

How can I display this in my html template?

I try to display in html file in this way:

<p>{{news.title}}</p>
<p>{{news.text}}</p>

But it's not working

Answer 1

You can go for :

angular.toJson(JSONObj);

So, here you can go for: in Controller:

displaydash.news = result.data;
$scope.news      = angular.toJson(displaydash.news);

in HTML:

<p>{{news}}</p>

The issue in your question is simple, you are trying to access news object which you have not defined, try creating a scope variable for it, you will be easily able to access it:

 $scope.displaydash.news = result.data;

<p>{{displaydash.news.title}}</p>
<p>{{displaydash.news.text}}</p>

Refer: https://docs.angularjs.org/api/ng/function/angular.toJson

如果result.data是一个对象，请用方括号括起来并设置为news ，否则直接使用它。

 displaydash.news = typeof(result.data) == "object"?[result.data]: result.data;
