jQuery JSONP跨域

直接上代码：

服务端test.jsp

String result=request.getParameter("data")==null?"null":request.getParameter("data");
String callback = request.getParameter("jsonpCallback")+"([{\"results\":"+result+"}])";
response.setHeader("Pragma", "no-cache");
response.setHeader("Cache-Control", "no-cache, must-revalidate");
response.setHeader("Pragma", "no-cache");
response.getWriter().write(callback);
response.getWriter().flush();
response.getWriter().close();

System.out.println("json:"+callback+"接收返回");


客户端test.html
$.getJSON("http://10.100.121.113:8081/test.jsp?jsonpCallback=?&data=90", function(data){      
        alert(data[0].results);     
    });
