而不是改变插件源代码，你可以包括一个额外的js文件，格式类似于下载本地化文件夹中的那些，并在加载validation.js后包括那个文件

jQuery.extend(jQuery.validator.messages, {
    required: ...,
    maxlength: jQuery.validator.format(...),
    ...
});

将此代码添加到验证插件后包含的单独文件/脚本中，以覆盖消息，随意编辑:)

jQuery.extend(jQuery.validator.messages, {
    required: "This field is required.",
    remote: "Please fix this field.",
    email: "Please enter a valid email address.",
    url: "Please enter a valid URL.",
    date: "Please enter a valid date.",
    dateISO: "Please enter a valid date (ISO).",
    number: "Please enter a valid number.",
    digits: "Please enter only digits.",
    creditcard: "Please enter a valid credit card number.",
    equalTo: "Please enter the same value again.",
    accept: "Please enter a value with a valid extension.",
    maxlength: jQuery.validator.format("Please enter no more than {0} characters."),
    minlength: jQuery.validator.format("Please enter at least {0} characters."),
    rangelength: jQuery.validator.format("Please enter a value between {0} and {1} characters long."),
    range: jQuery.validator.format("Please enter a value between {0} and {1}."),
    max: jQuery.validator.format("Please enter a value less than or equal to {0}."),
    min: jQuery.validator.format("Please enter a value greater than or equal to {0}.")
});

@Josh:你可以从你的资源包中翻译消息来扩展你的解决方案

<script type="text/javascript">
    $.validator.messages.number = '@Html.Raw(@Resources.General.ErrorMessageNotANumber)';
</script>

如果你把这段代码放到你的_Layout中。cshtml (MVC)，它可用于所有视图

添加自定义或字段标签或任何与正在验证的字段相关的动态标签。 你可以通过dom选择任何东西，并将其添加到任何带有错误消息的地方。

下面是一个在required消息开头添加字段标签而不是“this field”的例子。

jQuery.extend(jQuery.validator.messages, {

    required: function(result,e){

        let field_label = "This field ";

        if($(e).closest('.form-group').find('label').length > 0)
            field_label = $(e).closest('.form-group').find('label').html();

        return field_label+" is required.";

        },

});

您可以在验证调用中指定自己的消息。从验证插件文档(http://jquery.bassistance.de/validate/demo/milk/)中使用的Remember the Milk注册表单中提升和缩写这段代码，您可以轻松地指定自己的消息:

var validator = $("#signupform").validate({
    rules: {
        firstname: "required",
        lastname: "required",
        username: {
            required: true,
            minlength: 2,
            remote: "users.php"
        }
    },
    messages: {
        firstname: "Enter your firstname",
        lastname: "Enter your lastname",
        username: {
            required: "Enter a username",
            minlength: jQuery.format("Enter at least {0} characters"),
            remote: jQuery.format("{0} is already in use")
        }
    }
});
