$("button").click(function () {
$.post("/untitled/Servlet", {sname: $("#a").val(), spassword: $("#b").val()}, function (data) {
$("p").text(data)
});
$("button").text("已啟動")
})
})

Servlet程式碼：

@WebServlet(name="Servlet",urlPatterns ="/Servlet")
public class Myservlet extends HttpServlet {
public Myservlet() {
super();
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
System.out.println("------------------------------------");
String a=request.getParameter("sname");
String b=request.getParameter("spassword");
String data = "使用者名稱："+a+";密碼："+b;
response.setContentType("text/html;charset=utf-8");
response.setCharacterEncoding("UTF-8");
PrintWriter out = response.getWriter();
out.write(data);
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
}
}
