1.完成过程遇到几个问题：
1.1 用js实现注册手机号、邮箱、确认密码验证
首先要确定验证的正则表达式，网上有很多版本，其次难住的地方是无法引用，因为对js不熟悉，所以犯了很多”愚蠢“的错误。比如，js应写在body外面；值的传递是通过是value来进行的；引用onblur事件来触发函数。举个例子：
手 机 号：<input class="layui-btn layui-btn-primary layui-btn-radius" type="text" name="telephone" id="telephone" onblur="upperCase(this.value)" /><br>
script对应的代码 ：
<script type="text/javascript">
function upperCase(val){
//var val=document.getElementById(phone).value;
var reg=/^1[345678]\d{9}$/;
if (val==‘‘) {
alert("请输入手机号!")
}else if(reg.test(val)){
}else{
alert("手机号输入错误，请重新输入！!")
}
}
</script>
2.session的使用
实现创新年报搜索相关平台信息时用到了session传值
基本思路为：用list来传值平台类的属性值，用session的setAttribute来存一个对象，在jsp中用getAttribute来读取。举个例子：
servlet类
protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
// TODO Auto-generated method stub
req.setCharacterEncoding("utf-8");
String condition1 = req.getParameter("condition1");
String content1 = req.getParameter("content1");
String sql = "select PId,Pname,Pnum,approval_num,techField from platform where "+condition1+" like ‘%"+content1+"%‘";
Connection conn = DBUtil.getConnection();
PreparedStatement prep = null;
ResultSet rs = null;
List<platform> list = new ArrayList<platform>();
HttpSession session = req.getSession();
try {
prep = conn.prepareStatement(sql);
rs = prep.executeQuery();
while(rs.next()) {
platform platform = new platform();
platform.setPId(rs.getInt(1));
platform.setPname(rs.getString(2));
platform.setPnum(rs.getDate(3));
platform.setApproval_num(rs.getString(4));
platform.setTechField(rs.getString(5));
list.add(platform);
}
session.setAttribute("platforms", list);
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
resp.sendRedirect("/Innovation/NewSearch2.jsp");
}
