jQuery Validation plugin - Custom message
提问by Detonator
I am new to JQuery and am using the JQuery validation plugin.
我是 JQuery 的新手，正在使用JQuery 验证插件。
I would like to ask, how to override the default messages to display also text in label associated with form element.
我想问一下，如何覆盖默认消息以在与表单元素关联的标签中显示文本。
I would get message something like this:
我会收到这样的消息：
Field Password is required.instead of default This field is required.
字段密码是必需的。而不是默认此字段是必需的。
Field PostCode must contain at least 3 characters.instead of default Please enter at least 3 characters.
字段 PostCode 必须至少包含 3 个字符。而不是默认请输入至少 3 个字符。
I need to override the default behaviour of this plugin, because I do not want to specify custom message for each item for every type of validation.
我需要覆盖此插件的默认行为，因为我不想为每种类型的验证为每个项目指定自定义消息。
Is it possible?
是否可以？

required: true,
minlength: 3
}
},
messages: {

required: "Field PostCode is required",
minlength: "Field PostCode must contain at least 3 characters"
}
});

This is what I found when I was looking for the same thing a couple of days ago. Unfortunately I can't remember where I found it, so I can't give the person who wrote the answer credit.
这是我几天前在寻找同样的东西时发现的。不幸的是，我不记得我在哪里找到它，所以我不能给写答案的人功劳。
jQuery.extend(jQuery.validator.messages, {
required:"This field is required.",
equalTo:"Password fields do not match.",
email:"Please enter a valid email.",
});

There's a more concise way to achieve this.
有一种更简洁的方法可以实现这一点。
Use "data-msg" or "data-msg-(rulename)" to override default error message for a predefined rule or a custom rule. (after jQuery validation v1.11.0, currently v1.16.0)
使用“ data-msg”或“ data-msg-(rulename)”来覆盖预定义规则或自定义规则的默认错误消息。（在 jQuery 验证 v1.11.0 之后，目前是 v1.16.0）
<input id="pwd" name="pwd" type="password" value=""
required
data-msg-required="Field Password is required." />
<input id="postcode" name="postcode" type="text" value=""
required
data-msg-required="Field PostCode is required."
minlength="3"
data-msg-minlength="Field PostCode must contain at least 3 characters." />

I needed to do the same thing, and ended up creating a custom method so that its message could be shared across multiple forms.
我需要做同样的事情，并最终创建了一个自定义方法，以便它的消息可以在多个表单之间共享。
I found this answer in a similar Stack Overflow question: How can we specify rules for jquery validation plugin by class?
我在一个类似的 Stack Overflow 问题中找到了这个答案：我们如何按类指定 jquery 验证插件的规则？
$.validator.addMethod(
"newEmail", //name of a virtual validator
$.validator.methods.email, //use the actual email validator
"Custom error message"
);

add this after the plugin:
在插件后添加：
jQuery.extend(jQuery.validator.messages, {
required: "Your new default message",
email: "That's not a valid email"
});
you can put it in a separate file if you want, but make sure it's included after the plugin itself
如果你愿意，你可以把它放在一个单独的文件中，但要确保它包含在插件本身之后
