<%@ page contentType="text/html;charset=gb2312"%><html>
<body>
<form name="form1" action="forwardExample1.jsp" method="post" >

<select name="goaddress" onchange="javascript:form1.submit()">
<option value="novalue"></option>
<option value="1">实例13</option>
<option value="2">实例14</option>
<option value="3">实例15</option>
</select>
</form>
<%// forward应用示例Java程序片
