因为我们已经使用了JQuery，我们可以让页面设计者在标记中添加自定义消息，而不是代码:

<input ... data-msg-required="my message" ...

或者，更通用的解决方案是在所有字段上使用一个简短的data-msg属性:

<form id="form1">
    <input type="text" id="firstName" name="firstName" 
        data-msg="Please enter your first name" />
    <br />
    <input type="text" id="lastName" name="lastName" 
        data-msg="Please enter your last name" />
    <br />
    <input type="submit" />
</form>

然后代码包含如下内容:

function getMsg(selector) {
    return $(selector).attr('data-msg');
}

$('#form1').validate({
    // ...
    messages: {
        firstName: getMsg('#firstName'),
        lastName: getMsg('#lastName')
    }
    // ...
});

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.",
            }
        }
    })

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")
        }
    }
});

验证的完整API(…):http://jqueryvalidation.org/validate

我们可以指定文本字段的类型来代替这些自定义错误消息。

示例:设置字段类型为type = 'email'

然后插件将识别字段并正确验证。

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  
       });  
   });  

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