Question

我正在从angular到Spring进行REST调用。我能够得到回复。当我尝试使用ng-repeat填充视图中的值时，屏幕上不会显示任何内容。

这是我的Angular Code此代码在showhidecontroller

中

  var resuls = $http.post('http://localhost:8080/aeservices/AddConfig', dataobj);
          resuls.success(function(data, status, headers, config) {
                $scope.dbresponse= data;
                $scope.messagetest = $scope.dbresponse[0].messages;
                alert($scope.messagetest);
                console.log( $scope.messagetest);
                console.log(data);

                });

这是我从API

收到的回复

    [{
"data12": null,
"name": null,
"errors": ["error data1", "error data2"],
"messages": ["Configuration has been Added successfully", "Configuration has been Added successfully"]
}]

这是我的HTML

     <table ng-controller="ShowHideController">
<tr ng-repeat="item in dbresponse[0].errors" >
        <span><td align="left" class="validationMsg"><img src="images/red_bullet.gif" border="0" width="8" height="8" alt="">&nbsp
{{item}}
</td></span></tr>
</table>

我尝试使用ng-repeat，声明自己这样的项目是$ scope.items = ['one'，'two'，'three'，'four']。即使这没有出现在HTML上。

尝试使用data.data，

<强>控制器：

app.controller("listController", ["$scope", "$http",
  function($scope, $http) {
    $http.get('test.json').then(function(response) {
      $scope.dbresponse = response.data;
    });
  }
]);

<强> HTML：

  <table ng-controller="listController">
      <tr ng-repeat="item in dbresponse[0].errors">
        <td align="left" class="validationMsg"><img src="images/red_bullet.gif" border="0" width="8" height="8" alt=""> {{item}}
        </td>
      </tr>
  </table>

请尝试以下代码，不要声明变量结果。

  $http.post('http://localhost:8080/aeservices/AddConfig', dataobj).success(function(data, status, headers, config) {
                $scope.dbresponse= data;
                $scope.messagetest = $scope.dbresponse[0].messages;
                alert($scope.messagetest);
                console.log( $scope.messagetest);
                console.log(data);

                });
