删除所有默认错误消息

$.validator.messages.required = "";

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}.")
});

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(...),
    ...
});

最新版本有一些不错的内联功能。

如果它是一个简单的输入字段，您可以像这样添加属性data-validation-error-msg

data-validation-error-msg="Invalid Regex"

如果你需要一些更重的东西，你可以使用一个带有传递给validate函数的所有值的变量来完全自定义东西。详细信息请参考这个链接:https://github.com/victorjonsson/jQuery-Form-Validator#fully-customizable

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.";

        },

});

另一种可能的解决方案是遍历字段，向每个字段添加相同的错误消息。

$('.required').each(function(index) {
  $(this).rules("add", {
    messages: {
      required: "Custom error message."
   }
  });
});
