EXT读取后台json数据的问题
刚开始接触EXT，可以搞了2天了，一个小小的测试都没有搞出来
大侠们帮忙看看吧 ~~~ 后台能取到数据，可前台怎么都取不到json，页面上能显示出grid框和列 但是没有数据；大家看我的代码可能会发现我的列都是中文的，这是由于我们的项目的原因，我查过资料EXT对中文取值是支持的
我的jsp也是UTF-8的
json的后台打印：{"pageInfo":1,"data":[{"签发人":"","归档":"","登记号":"001","保管期限":"10年","文件标题":"关于什么的测试情况","原文路径":"","份数":"","主题词":"啊","备注":"","正文":"","归档份数":"","处理单":"","密级":"机密","责任者":"啊","拟稿人":"","办结提示":"","分类号":"020","成文日期":"20081009","页数":"1","全宗号":"","缓急程度":"","签发时间":"","拟稿部门":"","主办部门":"","文号":"综[2008]1号","附件":"","登记日期":"20081009"}]}
java（action）的写法：
[code="java"]JSONArray ary = new JSONArray(recodList);
JSONObject jo = new JSONObject();
jo.put("data", ary);
jo.put("pageInfo",recodList.size());
String jstr=jo==null?"":jo.toString();
boolean scriptTag = false;
String cb = request.getParameter("callback");
if (cb != null) {
scriptTag = true;
response.setContentType("text/html;charset=UTF-8");
} else {//"text/html;charset=UTF-8" "text/javascript;charset=UTF-8" "application/x-json;charset=UTF-8"
response.setContentType("text/html;charset=UTF-8");
}
if (scriptTag) {
jstr = cb + "("+jstr+")";
}
System.out.println(jstr);
response.getWriter().print(jstr);[/code]
