我正在尝试创建一个程序，用户可以在其中将匹配结果输入到 html 页面中，然后将该数据添加到数据库中，但我可以获取要插入的任何数据。我错了什么，这是我的代码：
<html>
<head>
<title>Result</title>
</head>
<body>
<FORM METHOD=GET ACTION="EnterResult.jsp">
Enter your home team:
<INPUT TYPE="text" NAME="newhomet" VALUE = "" >
Enter your away team:
<INPUT TYPE="text" NAME="newawayt" VALUE = "" >
Enter your home score:
<INPUT TYPE="text" NAME="newhomes" VALUE = "" >
Enter your away score:
<INPUT TYPE="text" NAME="newaways" VALUE = "" >
<INPUT TYPE="submit" VALUE = "Submit">
</FORM>
</body>
</html>
输入结果.jsp
<HTML>
<%@ page import="java.util.*" import="java.awt.*" import= "javax.swing.*" import= "java.sql.*" import= "java.util.* " import= "matchBean.*" errorPage= "NewError.jsp" %>
<jsp:useBean id="newMatchBean" class="matchBeans.MatchResults" />
<%
String newHomeTeam;
String newAwayTeam;
String newHomeScore;
String newAwayScore;
newHomeTeam = request.getParameter("newhomet");
newAwayTeam = request.getParameter("newawayt");
newHomeScore = request.getParameter("newhomes");
newHomeScore = request.getParameter("newaways");
%>
</HTML>
