今天寫代碼時碰到一個問題,無法從JavaScript中傳遞參數到action,後來得到老師協助解決了問題:

 

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@taglib prefix="s" uri="/struts-tags"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">
   
    <title>My JSP 'option.jsp' starting page</title>
   
 <meta http-equiv="pragma" content="no-cache">
 <meta http-equiv="cache-control" content="no-cache">
 <meta http-equiv="expires" content="0">   
 <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
 <meta http-equiv="description" content="This is my page">
 <!--
 <link rel="stylesheet" type="text/css" href="styles.css">
 -->

  <script type="text/javascript">
  function change(id)
  {
  window.location.href="option.action?courseId="+id;
  }
</script>
  </head>
 
  <body>
  <center><s:form action="" method="post">
   <s:select list="kch" name="wjtm.kcId.id" listKey="id"
   listValue="name" onchange="change(this.value)" headerKey="0" headerValue="--請選擇課程--"></s:select><br><br>
  </s:form></center>
  </body>
</html>
