使用jQuery的serializeArray() 方法序列化表单元素

　　　　如果表单元素很多，手工拼装成json数据非常麻烦，可以使用jQuery提供的serializeArray()方法序列化表单元素，返回json数据结构数据。　　

<%@ page language="java" contentType="text/html; charset=UTF-8"

    pageEncoding="UTF-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<title>Add User</title>

<script type="text/javascript" src="${pageContext.request.contextPath}/resource/script/jquery-1.9.1.min.js"></script>

<script type="text/javascript">

    $(document).ready(function(){

        $("#button_submit").click(function(){

            //序列化表单元素，返回json数据

            var params = $("#userForm").serializeArray();

            //也可以把表单之外的元素按照name value的格式存进来

            //params.push({name:"hello",value:"man"});

            $.ajax({

                type:"POST",

                url:"${pageContext.request.contextPath}/user/addUser5",

                data:params,

                success:function(data){

                    alert("成功");

                },

                error:function(e) {

                    alert("出错："+e);

                }

            });

        });

    });

</script>

</head>

<body>

    <form id="userForm">

        <table>

            <tr>

                <td>账号</td>

                <td>

                    <input type="text" id="userName" name="userName">

                </td>

            </tr>

            <tr>

                <td>密码</td>

                <td>

                    <input type="password" id="password" name="password">

                </td>

            </tr>

            <tr>

                <td>&nbsp;</td>

                <td>

                    <input type="button" id="button_submit" value="提交">

                </td>

            </tr>

        </table>

    </form>

</body>

</html>

　　依然可以使用bean来接收json数据：

@RequestMapping("/addUser5")

    public String addUser5(User user) {

        System.out.println("userName is:"+user.getUserName());

        System.out.println("password is:"+user.getPassword());

        return "/user/success";

    }
