1、问题描述,将一个table中的数据整个提交至后台转换成list
2、主要功能:
1)、表格数据json提交后台转成list,jsonObject
2)、后台list数据回显至前端表格,
3)、表格带增加行删除行功能,
4)、select元素回显
5)、jQuery ajax submit提交
3、前端提交表格数据
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <c:set var="ctx" value="${pageContext.request.contextPath}"/> <html> <head> <Meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> <form method="post" id="userFormID"> <table border="1" id="UserTableID"> <tr> <td style="width:10%">序号</td> <td style="width:10%">名字</td> <td style="width:10%">年龄</td> <td style="width:10%">性别</td> <td style="width:10%">操作</td> </tr> <tr > <td style="width:10%" number="1">1</td> <td style="width:10%" nameTd="1"> <input type="text" value="张三" jsonName='name' onfocus="if (value =='请输入'){value =''}"onblur="if (value ==''){value='请输入'}"></td> <td style="width:10%" ageTd="1"> <input type="text" value="22" jsonName='age' onfocus="if (value =='请输入'){value =''}"onblur="if (value ==''){value='请输入'}"></td> <td style="width:10%" sexTd="1"> <select jsonName='sex'> <option value="男" selected="selected">男</option> <option value="女" >女</option> </select> </td> <td style="width:10%" operTd="1"> <input type="button" value="delete" onclick="fnDeleteRow(this,'UserTableID')" style="float:left; margin-top:6px; margin-left:20%"> <input type="button" value="add" onclick="tbAddRow(this);" style="float:right; margin-top:6px; margin-right:20%"> </td> </tr> </table> <input type="button" value="提交" onclick="submitUser()" style="float:right; margin-top:6px; margin-right:20%"> </form> <input type="hidden" id="rootDir" value="${ctx}"> <script type="text/javascript" src="../js/jquery-1.8.2.js"></script> <script type="text/javascript" src="../js/jquery.form.min.js"></script> <script type="text/javascript" src="../js/angular.min.js"></script> <script type="text/javascript" src="../js/saveuser.js"></script> </body> </html>
4、js部分代码
//得到表格数据 function getUser(tableID){ var args = {}; $("#"+tableID+" tr:gt(0)").each(function(i){ var data = new Object(); $(this).find("select[jsonName],input[jsonName]").each(function(){ var name = $(this).attr("jsonName"); data[name]= $(this).val(); }); args[i]=data; }); alert("data;"+JSON.stringify(args)); return JSON.stringify(args); }
protected void doPost(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException { String users = request.getParameter("user"); if (users!=null&&!"".equals(users)) { JSONObject json=JSONObject.fromObject(users); int size = json.size(); List<User> list= new ArrayList<User>(); for (int i = 0; i < size; i++) { JSONObject o = (JSONObject) json.get(""+i); User b = (User) JSONObject.toBean(o,User.class); System.out.println(b.getName()); list.add(b); } } }

7、注意:demo 省去dao层,回显的数据是自定义的,与提交数据无关系
