开发进度3

今天用javaweb将家庭记账本的基本功能实现了,接下来将会开始从手机

端出发,趋向于用微信小程序开发。下面是程序的编写基本框架与过程

包的基本框架:

建立两张数据表,收入表与支出表,然后对应建立两个类,servlet等等,对两张数据表进行增删改查,现粘贴部分代码

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>

</head>
<body>
    <%
         Object message = request.getAttribute("message");
         if(message!=null && !"".equals(message)){
    %>
         <script type="text/javascript">
              alert("<%=request.getAttribute("message")%>");
         </script>
    <%} %>
    <div align="center">
        <h1 style="color: black;">收入列表</h1>
        <a href="index.jsp">返回主页</a>
        <table class="tb" border="1">
            <tr>
                <td hidden="hidden">id</td>
                <td>姓名</td>
                <td>日期</td>
                <td>方式</td>
                <td>说明</td>
                <td>金额</td>
                <td align="center" colspan="2">操作</td>
            </tr>
            <c:forEach items="${student1}" var="item">
                <tr>
                    <td hidden="hidden">${item.id}</td>
                    <td>${item.name}</td>
                    <td>${item.number}</td>
                    <td>${item.classroom}</td>
                    <td>${item.course}</td>
                    <td>${item.score}</td>
                    <td><a href="Servlet1?method=getstudentbyid&id=${item.id}">修改</a></td>
                    <td><a href="Servlet1?method=delete&id=${item.id}">删除</a></td>
                </tr>
            </c:forEach>
        </table>
    </div>
</body>
</html>

        <form action="Servlet1?method=update" method="post" onsubmit="return check()">
            <div class="a">

            </div>
        </form>
    </div>
    <script type="text/javascript">
    function check() {
        var name = document.getElementById("name");
        var number = document.getElementById("number");
        var classroom = document.getElementById("classroom");
        var course = document.getElementById("course");
        var score = document.getElementById("score);
        //非空
        if(name.value == '') {
            alert('姓名为空');
            name.focus();
            return false;
        }
        if(number.value == '') {
            alert('日期为空');
            number.focus();
            return false;
        }
        if(classroom.value == '') {
            alert('方式为空');
            classroom.focus();
            return false;
        }
        if(course.value == '') {
            alert('说明为空');
            course.focus();
            return false;
        }
        if(score.value == '') {
            alert('金额为空');
            score.focus();
            return false;
        }
    }
    </script>
</body>
</html>

在一个jsp中实现修改删除,省去了很多繁杂的过程,然后是结果的截图

 

 

 接下来具体的美化界面的操作将在开发微信小程序时实现
