Question

我在下面发布了我的代码以及我想要显示的JSON数据。具体来说，我希望能够{{client.label}}并将客户端放在列表中。不幸的是，唯一可行的是当我做{{client}}时，它给了我整个JSON对象，这是我不想要的。我是Angular的新手，我知道我显然做错了什么，但我不太清楚是什么。任何帮助表示赞赏！

<body ng-controller="myController">
  <ul>
    <li ng-repeat="client in userData">
      {{client.label}}
    </li>
  </ul>
  <script>
    var app = angular.module('myApp', []);
    app.controller("myController", function ($scope, $http) {
      $http({
        url: 'myURL/blah/blah',
        method: 'POST',
        data: {
          common: { clientName: '6012' },
          qualifier: '$ALL.$ALL.$ALL.$ALL.$ALL',
          pattern: 'configs\\..*'
        },
        headers: { 'Content-Type': 'application/json' }
      }).success(function(data) {
        $scope.userData = data;
      });
    });
  </script>
</body>

Answer 1

将ng-repeat更改为：

<li ng-repeat="client in userData.parameters[0].value">
  {{client.label}}
</li>

Answer 2

要迭代的数据不是返回但更深的数据。你应该改变 $scope = data; 至 $scope = data.parameters[0].value; 或者改变它重新调整的方式。

还有一件事，通常最好通过集中服务处理数据。
