有一个简单的方法来改变默认的错误值在jQuery验证插件?

我只是想重写错误消息,以使我的应用程序更加个性化——我有很多字段,所以我不想为字段x单独设置消息……我知道我能做到!

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.";

        },

});

@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

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  
       });  
   });
