之前我有这个工作......我无法弄清楚改变了什么来打破我的验证器插件。 当我点击提交按钮时，当我将许多字段留空时，我会收到一条提示，表明该表单有效。我在控制台中没有收到任何JS错误。

答案 0 :(得分：2)
.validate()函数添加到.onclick函数中。这是不对的。<input .. /> 问题在那里解决了。
使用此：
$().ready(function () {
var container = $('.error_container');
$("#purchase_premium").validate({
onkeyup: false,
onfocusout: false,
errorContainer: container,
errorLabelContainer: $("ol", container),
wrapper: 'li',
rules: {
account_type: {
required: true
},
first_name: {
required: true
},
last_name: {
required: true
},
address: {
required: true
},
city: {
required: true
},
email: {
required: true
},
state: {
required: true
},
cc_number: {
required: true,
creditcard: true
},
cc_cvc: "required",
password: {
required: true,
minlength: 6
},
password_confirm: {
equalTo: "#password"
}
},
messages: {
account_type: "Please select an account type.",
first_name: "Please enter your first name",
last_name: "Please enter your last name",
address: "Please enter your address",
city: "Please enter your city",
email: "Please enter a valid email address",
state: "Please select a state/province",
cc_number: "Please enter a valid credit card number",
cc_cvc: "Please enter a valid CVV/CVC Security Code",
password: {
required: "Please enter a password.",
minlength: "Your password must be at least 6 characters in length",
}
},
submitHandler: function (form) {
alert('valid');
// you can access form by `form` tag, for example $(form).serialize()
}
});
jQuery.extend(jQuery.validator.messages, {
equalTo: "Your two passwords do not match"
});
// if ($("#purchase_premium").valid()) {
// alert('valid');
// e.preventDefault();
// //$("#purchase_premium").submit();
// } else {
// e.preventDefault();
// }
});
此外，如果您想在表单有效时执行某些操作，请使用submitHandler处理程序：
$("#purchase_premium").validate({
// set some properties
// messages and
// rules
submitHandler: function(form) {
alert('valid');
// you can access form by `form` tag, for example $(form).serialize()
}
});
此外，您的HTML无效。你使用：
<input id="last_name" name='last_name' type="text" placeholder="Last Name">
但你必须使用：
<input id="last_name" name='last_name' type="text" placeholder="Last Name" />
请注意最后的/符号。
