1. JSP页面中准备模态框
<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>
div>
form>
div>
div>
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"}
