简单程序的小问题。接分了。
初学jsp在试着写了个登陆界面但调用不了javascript里的函数请大家帮忙看看哈。
<%@ page contentType= "text/html; charset=gbk " language= "java " import= "java.sql.* " errorPage= " " %>
<script language= "javascript ">
function on_submit()
{
if(form1.username.value= " ")
{
alert( "用户名不为空,请输入用户名 ")；
form1.username.focus();
return false;
}
if(form1.code.value= " ")
{
alert( "密码不能为空 ");
form1.code.focus();
return false;
}
if(form1.reputcode.value!=form1.code.value)
{
alert(两次输入密码不一致);
form1.code.reputcode.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( "错误email地址 ");
form1.email.focus();
return false;
}
}
}
</script>
