用javascript验证信息时出现了这个错误
我想用javascript验证提交的username和userpassword信息，但是编译时出现
org.apache.jasper.JasperException: /reg.jsp(29,1) Attribute name invalid for tag form according to TLD
我想是不是 <html:form method= "post " name= "reg " language= "javascript " action= "/reg " onsubmit= "return Check(); "> 这里写错了，或者还有其他的错误，请各位大虾指点一下小弟，谢谢

[解决办法]
把 <html:form method= "post " name= "reg " language= "javascript " action= "/reg " onsubmit= "return Check(); "> 句
的name= "reg "去掉,看看
[解决办法]
去掉language= "javascript "
[解决办法]
<html:form method= "post " name= "reg "action= "/reg ">
<script>
document.forms.reg.onsubmit = function()
{
return Check();
}
</script>
[解决办法]
document.reg.username.value 改成document.forms[0].username.value ,下面password也一样，
