Url: "/arweb/reserve/saveCode. action", // path
Data: "clientTel =" + clientTel + "& activityId =" + activityId,
Success: function (text) {$ ("# randomCode"). val (text );},
Error: function (text) {alert ("sorry, the user ID does not exist. Please enter the correct user ID ");}
});

Copy codeThe Code is as follows:
HttpServletResponse res = ServletActionContext. getResponse ();
Res. reset ();
Res. setContentType ("text/html; charset = UTF-8 ");
PrintWriter pw = res. getWriter ();
Pw. print (random );
