1. JSP页面中准备模态框
<!-- 详细信息模态框（Modal） --> <div> <div class="modal fade" id="queryInfo" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true"> <div class="modal-dialog"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button> <h4 class="modal-title" id="myModalLabel">详细信息</h4> </div> <form action="${pageContext.request.contextPath }/productServlet?type=info" method="post"> <div class="modal-body"> <div class="input-group"> <span class="input-group-addon">名 称</span> <input type="text" class="form-control" placeholder="请输入名称" id="name1" readonly="readonly"> </div> <br /> <div class="input-group"> <span class="input-group-addon">规格及型号</span> <input type="text" class="form-control" placeholder="请输入规格及型号" id="xinghao1" readonly="readonly"> </div> <br /> <div class="input-group"> <span class="input-group-addon">存 放 地 点</span> <input type="text" class="form-control" placeholder="请输入存放地点名称" id="address1" readonly="readonly"> </div> <br /> <div class="input-group"> <span class="input-group-addon">使 用 部 门</span> <input type="text" class="form-control" placeholder="请输入使用部门名称" id="department1" readonly="readonly"> </div> <br /> <div class="input-group"> <span class="input-group-addon">单 位</span> <input type="text" class="form-control" placeholder="请输入单位名称" id="unit1" readonly="readonly"> </div> <br /> <div class="input-group"> <span class="input-group-addon">数 量</span> <input type="text" class="form-control" placeholder="请输入数量" id="number1" readonly="readonly"> </div> <br /> <div class="input-group"> <span class="input-group-addon">单 价</span> <input type="text" class="form-control" placeholder="请输入单价" id="price1" readonly="readonly"> </div> <br /> <div class="input-group"> <span class="input-group-addon">金 额</span> <input type="text" class="form-control" placeholder="请输入金额" id="totalprice1" readonly="readonly"> </div> <br /> <div class="input-group"> <span class="input-group-addon">来 源</span> <input type="text" class="form-control" placeholder="请输入来源" id="come1" readonly="readonly"> </div> <br /> <div class="input-group"> <span class="input-group-addon">购 建 日 期</span> <input type="text" class="form-control" placeholder="请输入购建日期" id="buytime1" readonly="readonly"> </div> <br /> <div class="input-group"> <span class="input-group-addon">使 用 人</span> <input type="text" class="form-control" placeholder="请输入使用人名称" id="useperson1" readonly="readonly"> </div> <br /> <div class="input-group"> <span class="input-group-addon">经 办 人</span> <input type="text" class="form-control" placeholder="请输入经办人名称" id="handleperson1" readonly="readonly"> </div> <br /> <div class="input-group"> <span class="input-group-addon">管 理 员</span> <input type="text" class="form-control" placeholder="请输入管理员名称" id="admini1" readonly="readonly"> </div> </div> <div class="modal-footer"> <button type="button" class="btn btn-default" data-dismiss="modal">关闭</button> <!-- <button type="submit" class="btn btn-primary">提交</button> --> </div> </form> </div> <!-- /.modal-content --> </div> <!-- /.modal --> </div>
2.准备点击请求json数据的按钮(带着id请求数据)
<a class="queryA" href="javascript:void(0)" onclick="query(${register.id})"> <span class="glyphicon glyphicon-search"></span> </a>
3.JS处理按钮点击事件
function query(id) { alert(\'ajax请求之前\'); $.ajax({ url : "/small/productServlet", async : true, type : "POST", data : { "type" : "query", "id" : id }, // 成功后开启模态框 success : showQuery, error : function() { alert("请求失败"); }, dataType : "json" }); } // 查询成功后向模态框插入数据并开启模态框。data是返回的JSON对象 function showQuery(data) { $("#name1").val(data.name); $("#xinghao1").val(data.xinghao); $("#address1").val(data.address); $("#department1").val(data.department); $("#unit1").val(data.unit); $("#number1").val(data.number); $("#price1").val(data.price); $("#totalprice1").val(data.totalprice); $("#come1").val(data.come); $("#buytime1").val(data.buytime); $("#useperson1").val(data.useperson); $("#handleperson1").val(data.handleperson); $("#admini1").val(data.admini); // 显示模态框 $(\'#queryInfo\').modal(\'show\'); }
4.后台接收请求返回JSON
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { RegisterService service = new RegisterServiceImpl(); request.setCharacterEncoding("UTF-8"); response.setCharacterEncoding("UTF-8"); response.setContentType("text/html; charset=UTF-8"); String type = request.getParameter("type"); if (type != null && "add".equals(type)) { try { this.add(request, response, service); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } } if (type != null && "query".equals(type)) { try { this.query(request, response, service); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } } } protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { doGet(request, response); } public void query(HttpServletRequest request, HttpServletResponse response, RegisterService service) throws Exception { Integer id = Integer.parseInt(request.getParameter("id")); Register register = service.getRegisterById(id); Gson gson = new Gson(); String json = gson.toJson(register); System.out.println(json); response.getWriter().write(json); }
结果:
{"id":16,"name":"测试名称16","address":"测试地址2","department":"测试部门2","unit":"测试单位2","number":1,"price":1.5,"totalprice":1.5,"come":"来源2","buytime":"八月 23, 2017","useperson":"使用人2","handleperson":"经办人2","admini":"管理员部门2"}
5.最终效果:
{"id":16,"name":"测试名称16","address":"测试地址2","department":"测试部门2","unit":"测试单位2","number":1,"price":1.5,"totalprice":1.5,"come":"来源2","buytime":"八月 23, 2017","useperson":"使用人2","handleperson":"经办人2","admini":"管理员部门2"}
