废话少说直接上代码代码是程序员交流的最好方式哈哈:

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> 
<% 
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 'index.jsp' starting page</title> 
<meta http-equiv="pragma" content="no-cache">

<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">

<!-- 
<link rel="stylesheet" type="text/css" href="styles.css">

<script type="text/javascript" src="js/jquery-1.8.2.js"></script> 
<script type="text/javascript"> 
function selectChange(obj){ 
var value=obj.value; 
var v1 = document.getElementById("tr1"); 
var v2 = document.getElementById("tr2"); 
if(value==0){ 
console.log("two is hidden"); 
v1.style.display="none"; 
v2.style.display="none"; 
}else if(value==1){ 
v1.style.display="block"; 
v2.style.display="none"; 
}else{ 
v1.style.display="none"; 
v2.style.display="block"; 
//将里面的值设为空 
} 
} 
</script> 
</head> 
<center> 
<body > 
<form action="GetJSPContent" method="post"> 
<table> 
<tr> 
<td>通知标题</td> 
<td><input type="text" name="title"/></td> 
</tr> 
<tr> 
<td>通知内容</td> 
<td><textarea cols="50" rows="10" name="cxt" >内容这块暂时没处理,本次测试用例 需要10个汉字以上测试</textarea></td> 
</tr> 
<tr> 
<td>通知类型</td><td><select onchange="selectChange(this)"> 
<option value="0" select="true">所有用户</option> 
<option value="1">用户组</option> 
<option value="2">单用户</option> 
</select></td> 
</tr> 
<tr id="tr1" style="display:none"> 
<td> 输入标签：</td><td><input type="text" id="tag1" name="tag"></td> 
</tr> 
<tr id="tr2" style="display:none"> 
<td> 输入号码：</td><td><input type="text" id="phone" name="phone"></td> 
</tr> 
<tr> 
<td><input type="submit"/></td> 
<td><input type="reset"/></td> 
</tr> 
</table> 
</form> 
</body> 
</center> 
</html>
