Java web停车场停车管理系统 下载好eclipse 停车信息注册界面： （一）看一下代码
</head> <body> <div class="main-wrap1"> <div class="crumb-wrap"> <div class="crumb-list"> <i class="icon-font"></i><span>用户注册</span> </div> </div> <div class="result-wrap"> <div class="result-content"> <form method="post" id="myform" name="myform"> <table class="insert-tab" width="100%"> <tbody> <tr> <th> <i class="require-red"></i>登录名： </th> <td> <input class="common-text required" id="name" name="name" size="50" value="" type="text"> </td> </tr> <tr> <th> <i class="require-red"></i>密码： </th> <td> <input class="common-text required" id="pwd" name="pwd" size="50" value="" type="text"> </td> </tr> <tr> <th> <i class="require-red"></i>年龄： </th> <td> <input class="common-text required" id="age" name="age" size="50" value="" type="text"> </td> </tr> <tr> <th> <i class="require-red"></i>电话： </th> <td> <input class="common-text required" id="tel" name="tel" size="50" value="" type="text"> </td> </tr> <tr> <th></th> <td> <input class="btn btn-primary btn6 mr10" onclick="save();" value="提交" type="button"> <input class="btn btn6" onclick="history.go(-1)" value="返回" type="button"> </td> </tr> </tbody> </table> </form> </div> </div> <!--/main--> </div> </body>function save() { if ($("#name").val() == “”) { KaTeX parse error: Expected 'EOF', got '}' at position 66: … return; }̲ if (("#pwd").val() == “”) { $.messager.alert(‘警告’, ‘密码不能为空！’, ‘warning’); return; } document.forms[0].action = “<%=path%>/RegUserinfoAction”; document.forms[0].submit();
}
注册Servlet程序： 代码如下：
package com.liu.action; import java.io.IOException; import java.io.PrintWriter; import java.sql.*; import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import com.biyeseng.db.DBManager; public class RegUserinfoAction extends HttpServlet {
private static final long serialVersionUID = 1L; public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/html"); PrintWriter out = response.getWriter(); String name=request.getParameter("name"); String pwd=request.getParameter("pwd"); String age=request.getParameter("age"); String tel=request.getParameter("tel"); DBManager dbm = new DBManager(); //用户注册 String sql = "insert into userinfo(name,pwd,age,tel,jine) values('"+name+"','"+pwd+"','"+age+"','"+tel+"','0')"; Statement stat = null; Connection conn=null; try { conn=dbm.getConnection(); stat = conn.createStatement(); System.out.println(sql); stat.execute(sql); } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); } finally { try { if(stat!=null) stat.close(); if(conn!=null) conn.close(); } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); } } out.println("<script>alert('注册成功请登录！');window.location.href='login.jsp'</script>"); out.flush(); out.close(); }} 示例：
