Question

我在访问嵌套的JSON值时遇到问题。我得到了另一个价值，它只是嵌套的，我有问题。我试图遵循这个例子，但无法让它工作。 Accesing nested JSON with AngularJS

<div ng-app="myApp" ng-controller="customersCtrl"> 
<ul>
  <li ng-repeat="x in myData">
{{ x.Body + ', ' + x.title + ', ' + x.test_l.filename + ', ' +  x.test_h.filename }}
</li>
</ul>
<!--problem here -->
<ul ng-repeat="x in myData" ng-show="isVisible(x.title)">
  <li ng-repeat="y in x.image">{{y.filename}}</li>
</ul>

我的问题是最后一部分。我正在尝试获取图像的所有文件名。

var app = angular.module('myApp', []);
app.controller('customersCtrl', function($scope, $http) {
 $http.get("http://localhost:8012/Adrupal/apistuff/test.json").then(function(response) {
      $scope.myData = response.data;
  });
});

Answer 1

ng-show="isVisible(x.title)"的问题。使用ng-show="x.title"代替ng-show="isVisible(x.title)"。

Answer 2

解决方案很简单，在您的情况下，您只需要获取数组的第一个元素（对象嵌套的位置）。

$scope.myData = response.data[0];

Answer 3

我解决了。如果其他人有同样的问题，这是我的解决方案。

<ul ng-repeat="x in myData">
 <li ng-repeat="y in x.image">{{y.filename}}</li>
</ul>
