JSP验证函数为什么不执行？ 代码如下！！！
<%@ page language="java" import="java.util.*" pageEncoding="gb2312"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path + "/";
%>

<script language="JavaScript">
<!--
function check(){//验证数据的合法性
alert('test');
if(form1.username.value == ""){
alert("用户名不能为空，请输入用户名！");
form1.username.focus();
return false;
}
if(form1.userpassword.value == ""){
alert("用户密码不能为空，请输入密码！");
form1.userpassword.focus();
return false;
}
if(form1.reuserpassword.value == ""){
alert("用户确认密码不能为空，请输入密码！");
form1.reuserpassword.focus();
return false;
｝
if(form1.userpassword.value != form1.reuserpassword.value){
alert("密码与确认密码不同！");
form1.password.focus();
return false;
}
if(form1.email.value.length != 0){
for(i=0;i<form1.email.value.length;i++)
if(form1.email.value.charAt(i)=="@")break;
if(i==form1.email.value.length){
alert("非法的E-Mail地址！");
form1.email.focus();
return false;
}
}else{
alert("请输入E-Mail!");
form1.email.focus();
return false;
}
return true;
}

新用户注册
<br>
用户名(*):
<input type="text" name="username" size="20">
<br>
密 码(*):
<input type="password" name="userpassword" size="20">
<br>
再输一次密码(*):
<input type="password" name="userpassword" size="20">
<br>
<input type="submit" value="提交" name="B1" onclick="check()">
<input type="reset" value="全部重写" name="B2">
<Br>
</form>
</body>

答案：if(form1.userpassword.value == ""){
alert("用户密码不能为空，请输入密码！");
form1.userpassword.focus();
return false;
}//这个括号是中文的，你改成英文的就行了 }
另，调JS建议用firefox浏览器，装上firebug插件。上一个：谁有jsp+javaBean访问access数据库的代码啊 ，能执行出来的，编了好几天总是出错，我快绝望了!!!
下一个：jsp中怎么实现一个表单中放两个按钮，这是我的代码 不知道哪里有问题~
