使用AngularJS在JSON URL中显示数据

Question

I'm new to ionic/angularjs and I need to know how to display data to a HTML view from a Json url.

So, data in my Json URL looks like this:

{
  News: [
        {
          id: "1",
          title: " It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.",
          image: "uploads/news/fortunaglobal_logo.jpg",
          status: "yes"
        },
        {
          id: "2",
          title: "fgdf",
          description: "hhjgh",
          image: "uploads/news/16613_10204428208286459_7484489390034618482_n.jpg",
          status: "yes"
        }
      ]
}

I tried this in my script:

.controller('NewsCtrl', function($scope, $http) {   

        $http.get('    "JSON URL"   ')
           .success(function(response, status, headers, config){

              window.alert('came in');
              if(status==200){

                 $scope.news = response.data['News'];
                 window.alert($scope.news );

              } else {
                 window.alert('No internet Connection');
              }
              console.log(news);
           })
          .error(function(data,status,headers,config){
              window.alert('error '+data+status);
              console.log(data);
              console.log(status);
         });
})

And this in my html page

<ion-view title="News" ng-controller="NewsCtrl">
    <ion-nav-buttons side="left">
        <button menu-toggle="left" class="button button-icon icon ion-navicon"></button>
    </ion-nav-buttons>


    <ion-content  class="has-header" scroll="true" padding="true">




    <ul ng-repeat="newsS in news">
      <li>{{newsS.title}}</li>
    </ul>


    </ion-content>
</ion-view>

Can someone explain to me what I am doing wrong?

Answer 1

Since you are not specific enough I can only guess what you're trying to get at, but I see some things that might be problematic:

$scope.news = response.data['News'];

If your described JSON from above is the full response, this data should directly be contained in your response element (which is actually supposed to be named data according to the angular documentation).

So try this instead:

$scope.news = response.News;

Next thing that can't work is

console.log(news);

Your variable news is nowhere defined, maybe you meant to use $scope.news ?
