你好我有一个php文件在远程服务器上运行，它抓取类别列表并将它们存储为JSON格式。该文件名为index.php的（这里的输出）：在下拉菜单中显示角度应用程序中的JSON数据

我试图抓住类别在这一JSON数据，并通过Ajax调用一个下拉菜单中的角应用中展示它。这里是我main.js代码文件的AJAX调用：
$http.get('http://test.s17.sevacall.com/abhas/index.php').
success(function(data, status, headers, config) {
console.log(data);//debug
$scope.categories = data;
}).
error(function(data, status, headers, config) {
//log error
});
这里是我的显示在下拉菜单从AJAX调用数据的HTML文件代码：
<div ng-controller="MainCtrl">
<span class="dropdown" on-toggle="toggled(open)">
<a href class="dropdown-toggle">
Click me to see some awesome things!
</a>
<ul class="dropdown-menu">
<li ng-repeat="category in categories track by $index"> <!--fix this expression-->
<a href>{{category}}</a>
</li>
</ul>
</span>
</div>
我的问题是，JSON数据打印在下拉菜单中，但下拉菜单按字符显示JSON数据，而不仅仅是下拉菜单中每行的类别。它的格式不正确。我很感激任何帮助，我可以收到关于如何解决这个问题，并让我的下拉菜单显示只是类别。
在此先感谢！

谢谢Toress，不幸的是这导致我的html页面显示一个空白的下拉菜单，跨越页面的全长。由于某种原因，我的JSON数据已完全消失 – 2014-11-02 16:54:00
您确定获取响应JSON对象而不是字符串吗？试试看'$ scope.categories = JSON.parse（data）;' – Hatsjoem 2014-11-02 16:55:47
