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

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}.")
});

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."
   }
  });
});

我从未想过这是如此容易，我正在从事一个处理此类验证的项目。

下面的答案将对那些想要轻松更改验证消息的人有很大帮助。

下面的方法使用“占位符名称”来代替“This Field”。

你可以很容易地修改东西

   // Jquery Validation   
   $('.js-validation').each(function(){

       //Validation Error Messages 

       var validationObjectArray = [];

       var validationMessages = {};

       $(this).find('input,select').each(function(){  // add more type hear

          var singleElementMessages = {};

          var fieldName = $(this).attr('name');

          if(!fieldName){  //field Name is not defined continue ;
              return true;
          }


          // If attr data-error-field-name is given give it a priority , and then to placeholder and lastly a simple text

          var fieldPlaceholderName = $(this).data('error-field-name') || $(this).attr('placeholder') || "This Field";

          if( $( this ).prop( 'required' )){

              singleElementMessages['required'] = $(this).data('error-required-message') || $(this).data('error-message')  || fieldPlaceholderName + " is required";

          }

          if( $( this ).attr( 'type' ) == 'email' ){

              singleElementMessages['email'] = $(this).data('error-email-message') || $(this).data('error-message')  || "Enter valid email in "+fieldPlaceholderName;

          }       



          validationMessages[fieldName] = singleElementMessages;

       });


       $(this).validate({
          errorClass   : "error-message",
          errorElement : "div",
          messages     : validationMessages  
       });  
   });  

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.";

        },

});

这招对我很管用:

// Change default JQuery validation Messages.
$("#addnewcadidateform").validate({
        rules: {
            firstname: "required",
            lastname: "required",
            email: "required email",
        },
        messages: {
            firstname: "Enter your First Name",
            lastname: "Enter your Last Name",
            email: {
                required: "Enter your Email",
                email: "Please enter a valid email address.",
            }
        }
    })
