當天的問候!!!將一組單選按鈕的值傳遞給servlet
我創建了一個JSP文件如下:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org /TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<form action="TestAms" method="post">
<%
for(int i=0; i<5; i++){
%>
<input type="radio" name="<%= i%>" value="<%=i %>">
<%
}
%>
<input type="submit" value="SUBMIT">
</form>
</body>
</html>
variable.Now我想要得到的單選按鈕的值,這個程序創建一個循環有名稱和值相同環路5個單選按鈕在servlet中。對於我的servlet的代碼如下:
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class TestAms extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
PrintWriter out = response.getWriter();
for (int i=0; i<5; i++){
String s[] = new String[5];
s[i] = request.getParameter("<%= i%>");
out.println(s[i]);
}
}
}
但我只用5「空」值結束。我知道問題在哪裏。但我無法找到一種方法將循環變量傳遞給request.getParameter()方法。請幫助我..... Thnx提前!
