[解决办法]
是不是页面出错了啊。。 你下面既然是 return check(); 就不要用 form.submit(); 这个提交啊。。直接return true;
[解决办法]
function check()//判断用户的输入是否合法
{
var from = document.forms[0];
if (form.username.value==""){
alert("请输入用户名！");myform.username.focus();return false;
}
[解决办法]
}
[解决办法]
form.username.value 改成 myform.UserName.value
其它的form 都改成表单名字 myform
[解决办法]
