用JS验证输入必须为中文为什么输入是中文还是一直弹提示
贴代码如下:
<!DOCTYPE html>
<html>
<head>
<meta charset="gbk">
<title>Insert title here</title>
</head>
<body>
<div align="center">
<form action="sub.jsp" method="post" onsubmit="return toVaild();" >
用户名:<input type="text" id="user" /><br />
密码:<input type="password" id="password" /><br/>
姓名:<input type="text" id="first" /><br/>
男性:<input type="radio" checked="checked" id="Sex" name="m" value="male" /><br />
女性:<input type="radio" id="Sex" name="m" value="female" /><br/>
编号:<input type="text" id="no" /><br/>
电话号码:<input type="text" id="phone" /><br/>
身份证号码:<input type="text" id="IDcard" /><br/>
邮箱地址:<input type="text" id="email" /><br/>
