jquery ajax提交表单从action传值到jsp实现小结

var clientTel = $("#clientTel").val(); 
var activityId = $("#activityId").val(); 
$.ajax({ 
type : "post",//发送方式 
url : "/arweb/reserve/saveCode.action",// 路径 
data : "clientTel="+clientTel+"&activityId="+activityId , 
success: function(text){$("#randomCode").val(text);}, 
error: function(text) {alert("对不起,用户ID不存在,请输入正确的用户ID");} 
});

HttpServletResponse res = ServletActionContext.getResponse(); 
res.reset(); 
res.setContentType("text/html;charset=utf-8"); 
PrintWriter pw = res.getWriter(); 
pw.print(random); 
pw.flush(); 
pw.close();
