<%@ page language="java" import="java.util.*" pageEncoding="GB18030"%>
<%
	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 'Jquery006.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">

		<script type="text/javascript" src="js/jquery-1.6.1.js"></script>
		<!-- 获得选中的option对象 -->
		<script type="text/javascript">
			$(document).ready(function() {
				$("#s1").change(function() {
					var str = "";
					//select :selected 注意中间有空格，少了空格就没有效果了
					$("select :selected").each(function() {
						str += $(this).text() + ',';
					});
					$("#div1").html('<b>' + str + '</b>');
				});
			});
		</script>
