JS实现简单的检查邮件格式是否正确：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>检查邮箱密码</title>
</head>
<body>
<form action="http://www.shuaiqi100.com" onsubmit="checkForm()">
邮件：<input type="text" name="email" id="email"><br/>
密码：<input type="password" name="Pass" id="pass"><br/>
<input type="submit" value="密码">
</form>
<script>
function checkForm()
{
var email = document.getElementById("email").value;
var pass = document.getElementById("pass").value;
//判断邮件格式是否找到@字符
if(email.indexOf("@") == -1)
{
alert("请输入正确的邮箱格式！");
event.returnValue = false;
document.getElementById("email").focus();
return;
}
if(email.indexOf(".") == -1)
{
alert("请输入正确的邮箱格式！");
event.returnValue = false;
return;
}
//检查密码是否符合条件
if(pass.length < 6)
{
alert("密码长度不能小于6！");
event.returnValue = false;
return;
}
}
</script>
</body>
</html>
