extjs 代理 proxy 获取html里面json 的问题

这是extjs的代码
Ext.regModel('User',{
fields:[
{name: 'appeId'},
{name: 'survId'},
{name: 'location'},
{name: 'surveyDate'},
{name: 'surveyTime'},
{name: 'inputUserId'}
]

});
var proxy=new Ext.data.proxy.Ajax({
     type:'ajax',
      url:'survey.html' 
});

//构建Store   
    var store=new Ext.data.Store({
      proxy:proxy,
      model:'User',
      autoLoad: true,
      render:'json'


   });
store.add({appeId:'qwe',survId:'123',location:'123',surveyDate:'s',surveyTime:'s',inputUserId:'s'});
store.sync();
//载入
store.load();
// create the grid
var grid = new Ext.grid.GridPanel({
    store: store,        
    columns: [
        {text: "appeId", width: 60, dataIndex: 'appeId', sortable: true},
        {text: "survId", width: 60, dataIndex: 'survId', sortable: true},
        {text: "location", width: 60, dataIndex: 'location', sortable: true},
        {text: "surveyDate", width: 100, dataIndex: 'surveyDate', sortable: true},
        {text: "surveyTime", width: 100, dataIndex: 'surveyTime', sortable: true},
        {text: "inputUserId", width:80, dataIndex: 'inputUserId', sortable: true}
    ],
    renderTo:'example-grid',
    width:540,
    height:200
});



    这是survey.html
    [{"appeId":"1","survId":"1","location":"","surveyDate":"2008-03-14","surveyTime":"12:19:47","inputUserId":"1","inputTime":"2008-03-14

12:21:51","modifyTime":"0000-00-0000:00:00"}]

值传不过来啊，store.add 自己添加的能显示出来。

你怎么返回的，是通过response.getWriter().println返回的吗

不是的，我是生成json了。不过解决了，是json格式的问题，之前改了我忘记了。谢谢！

你的reader可以读出你发出来的这个数据。你的是html静态页面，注意不要用post请求，有些服务器静态页面是不允许post请求的

而且你store已经配置为autoLoad就不需要在调用load方法了

private String getResponseText(Object content){
ObjectMapper mapper = new ObjectMapper();
try {
System.out.println(content.toString());
return mapper.writeValueAsString(content);
} catch (JsonGenerationException e) {
//logger.error("JsonGenerationException "+e.getLocalizedMessage());
e.printStackTrace();
} catch (JsonMappingException e) {
//logger.error("JsonMappingException "+e.getLocalizedMessage());
e.printStackTrace();
} catch (IOException e) {
//logger.error("IOException "+e.getLocalizedMessage());
e.printStackTrace();
}
return null;
}
