<script type="text/javascript">
$(document).ready(function () {
$("#loginForm").validate({
rules: {
email: {
required: true,
minlength: 10
},
passwd: {
required: true,
minlength: 8
}
},
messages: {
email: {
required: "Please enter your email",
minlength: "Minlength has to be 10"
},
passwd: {
required: "Please enter your email",
minlength: "Minlength has to be 8"
}
},
submitHandler: function (form) {
alert('valid form submit');
}
});
})
</script>
我在 HTML head 中有这个_
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.js"></script>
<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.12.0/jquery.validate.min.js"></script>
上面的 jQuery 位于关闭 body 标记之前的末尾。
当我使用 http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.js 时，以下代码在 jsfiddle 上运行得非常好和 http://ajax.aspnetcdn.com/ajax/jquery.validate/1.12.0/jquery.validate.min.js .
但在我的浏览器上，它总是转到提交处理程序。 http://jsfiddle.net/4937t/
非常感谢您的宝贵时间。

我不确定您是如何将脚本包含在 html 文档中的，但让我向您展示工作示例。它适用于我的 chrome。我猜你的脚本位置放错了。希望这有效
<!doctype html>
<html>
<body>
<form id="loginForm">
<input name="email" type="text"/><br/>
<input name="passwd" type="password"/><br/>
<input type="submit" />
</form>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.js"></script>
<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.12.0/jquery.validate.min.js"></script>
<script>
$(document).ready(function () {
$("#loginForm").validate({
rules: {
email: {
required: true,
minlength: 10
},
passwd: {
required: true,
minlength: 8
}
},
messages: {
email: {
required: "Please enter your email",
minlength: "Minlength has to be 10"
},
passwd: {
required: "Please enter your password",
minlength: "Minlength has to be 8"
}
},
submitHandler: function (form) {
alert('valid form submit');
}
});
});
</script>
</body>
</html>
