从PHP AngularJS获取JSON没有显示在控制器 [英] Getting JSON with AngularJS from PHP is not showing on controller
问题描述
我试图构建基于前端到后端PHP基础应用的AngularJS。我建立一个PHP和放大器JSON对象; MySQL查询。该JSON是正确导出，如果我使用内嵌客体与 NG-INIT 指令数据所示。但是，当我安装在控制器东西 Json.php 文件似乎是错误的，因为我没有看到任何数据。
I am trying to build an AngularJS based front-end to a PHP back-end base application. I build the JSON object with a PHP & MySQL query. The JSON is exported correctly and the data is shown if i use the objet inline with an ng-init directive. But when I mount the Json.php file on the controller something seem to be wrong because I don't see any data.
这是中的链接的例子中，在这里，控制器是<$ C $下方C>＆LT; /身体GT; 标记。
This is the link to the example, Here the controller is beneath the </body>tag.
这是主要的页
<html ng-app="myApp">
<head>
<title></title>
</head>
<body>
<div style="direction: ltr">
</div>
<h1>תוצאות שאלון</h1>
<div class="table-responsive" ng-controller="ContentCtrl">
<table class="table" id="results" >
<thead>
<tr>
<th>id</th>
<th>q1</th>
<th>q2</th>
<th>q3</th>
<th>textarea</th>
<th>phone</th>
<th>name</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="answer in answers.data">
<td>{{answer.id}}</td>
<td>{{answer.q1}}</td>
<td>{{answer.q2}}</td>
<td>{{answer.q3}}</td>
<td>{{answer.textarea}}</td>
<td>{{answer.phone}}</td>
<td>{{answer.name}}</td>
</tr>
<?php/*
$table = new Results();
$table->allrows();
*/?>
</tbody>
</table>
</div>

这是控制器：
var myApp = angular.module('myApp', []);
myApp.controller('ContentCtrl', ['$scope', '$http', function ($scope, $http) {
$http.get('json.php')
.success(function(data) {
$scope.answers = data;
console.log('test');
});
}]);
也许模块应该另一页上？
我问<一个href=\"http://stackoverflow.com/questions/34941448/php-export-array-to-json-for-an-angular-app/34941966?noredirect=1#comment57616213_34941966\">this问题早。也许它可以帮助弄好了。
Maybe the module should be on another page? I asked this question earlier. Maybe it can help somehow.
推荐答案
这是你的 json.php 文件与响应的JSON只是对象的数组。但是，你的 NG-重复是遍历 answers.data ，这是不确定的。你应该遍历答案因为这是该数组。
The JSON that your json.php file responds with is just an array of objects. But your ng-repeat is iterating over answers.data, which is undefined. You should iterate over answers since that's the array.
<tr ng-repeat="answer in answers">
如果由于某种原因你不想更改 NG-重复，那么你就可以改变你的控制器，以便它包装数据中的对象是这样的：
If for some reason you don't want to change the ng-repeat, then you can change your controller so that it wraps data in an object like this:
$scope.answers = { data: data };
