效果图

jsp代码

<form > 姓名：<input name="name" type="text"/> 年龄：<input name="age" type="text"/> <input type="button" class="get" value="get提交"/> <input type="button" class="post" value="post提交"/> <input type="button" class="ajax" value="ajax提交"/> </form> <div id="box"></div>

servlet代码

//getpublic void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/html"); response.setCharacterEncoding("utf-8"); response.setContentType("text/html;charset=utf-8"); String name = request.getParameter("name"); String age = request.getParameter("age"); if (name == null || name == "") { name = "测试名字admin"; } if (age == null || age == "") { age = "测试年龄100"; } user user = new user(1, name, age); PrintWriter out = response.getWriter(); JSONObject jsonObj = JSONObject.fromObject(user); out.print(jsonObj); out.flush(); out.close(); }//postpublic void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // response.setContentType("text/html"); request.setCharacterEncoding("utf-8"); response.setCharacterEncoding("utf-8"); response.setContentType("text/html;charset=utf-8"); String name = request.getParameter("name"); if (name == null || name == "") { name = "测试名字admin"; } String age = request.getParameter("age"); if (age == null || age == "") { age = "测试年龄100"; } user user = new user(1, name, age); PrintWriter out = response.getWriter(); JSONObject jsonObj = JSONObject.fromObject(user); out.print(jsonObj); out.flush(); out.close(); }

JS核心代码

<script type="text/javascript"> //get $(document).ready(function() { $('form .get').click(function() { $.get('ajaxServlet',function(response,status,xhr){ var dataObj = eval("(" + response + ")"); $("#box").html(response); alert(dataObj.name); }); }); //post $('form .post').click(function() { $.post('ajaxServlet',function(response,status,xhr){ var dataObj = eval("(" + response + ")"); $("#box").html(response); }); }); //ajax $('form .ajax').click(function() { alert($("[name='name']").val()); $.ajax({ type:'get', url:'ajaxServlet', data:{ name:$("[name='name']").val(), age:$("[name='age']").val() }, success:function(response, status, xhr){ $("#box").html(response);} }); }); });</script>
