最近遇到个奇怪的问题，使用Ext 的Store获取服务器的json数据时，浏览器显示一个下载对话框，下载的文件里就是json数据，不知道问什么浏览器把json数据当做文件下载了而不是存在Store中。
我的代码如下：
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<title>Basic Tree Demo</title>
<link type="text/css" rel="Stylesheet" href="../../ext-4.0.2a/resources/css/ext-all.css" />
<script type="text/javascript" src="../../ext-4.0.2a/ext-all-debug.js"></script>
<script type="text/javascript" language="javascript">
Ext.onReady(function () {
Ext.define('City', {
extend: 'Ext.data.Model',
fields: [{
name: 'id', type: 'int'
}, {
name: 'name', type: 'string'
}, {
name: 'p_id', type: 'int'
}, {
name: 'iscity', type: 'boolean'
}]
});
var citystore = Ext.create('Ext.data.Store', {
model: 'City',
proxy: {
type: 'ajax',
url: '../../Controllers/TreeDemoController/TreeCities',
reader: {
type: 'json',
model: 'City'
}
},
autoLoad: true
});
Ext.create('Ext.grid.Panel', {
title: '城市表',
store: citystore,
columns: [{
header: 'City Id', dataIndex: 'id'
}, {
header: 'City Name', dataIndex: 'name'
}, {
header: 'Parent Id', dataIndex: 'p_id'
}, {
header: 'Is City', dataIndex: 'iscity'
}],
renderTo: Ext.getBody()
});
});
</script>
</head>
<body>
<div>
</div>
</body>
</html>
下载的文件里的内容是这样的：
[{"id":1,"name":"中国","p_id":0,"iscity":false},{"id":2,"name":"安徽","p_id":1,"iscity":false},{"id":3,"name":"江苏","p_id":1,"iscity":false},{"id":4,"name":"浙江","p_id":1,"iscity":false},{"id":5,"name":"合肥","p_id":2,"iscity":true},{"id":6,"name":"安庆","p_id":2,"iscity":true},{"id":7,"name":"芜湖","p_id":2,"iscity":true},{"id":8,"name":"南京","p_id":3,"iscity":true},{"id":9,"name":"杭州","p_id":4,"iscity":true},{"id":10,"name":"无锡","p_id":3,"iscity":true},{"id":11,"name":"苏州","p_id":3,"iscity":true}]
不知道错在哪里，请高手们指点，谢谢！

后台逻辑你写成了下载了吧
