創新年報平臺系統完成過程遇到的問題

1.完成過程遇到幾個問題：

1.1 用js實現註冊手機號、郵箱、確認密碼驗證

首先要肯定驗證的正則表達式，網上有不少版本，其次難住的地方是沒法引用，由於對js不熟悉，因此犯了不少」愚蠢「的錯誤。好比，js應寫在body外面；值的傳遞是經過是value來進行的；引用onblur事件來觸發函數。舉個例子：

手 機 號：<input class="layui-btn layui-btn-primary layui-btn-radius" type="text" name="telephone" id="telephone" onblur="upperCase(this.value)" /><br>
			

　　script對應的代碼 ：

<script type="text/javascript">
		function upperCase(val){
   			//var val=document.getElementById(phone).value;
   			 var reg=/^1[345678]\d{9}$/;
    		if (val=='') {
				alert("請輸入手機號!")
    		}else if(reg.test(val)){
    		}else{
			alert("手機號輸入錯誤，請從新輸入！!")
    	}  
}
</script>

　　2.session的使用

實現創新年報搜索相關平臺信息時用到了session傳值

基本思路爲：用list來傳值平臺類的屬性值，用session的setAttribute來存一個對象，在jsp中用getAttribute來讀取。舉個例子：

servlet類

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");
	}
