Parsley has some built-in ways of adding custom error messages.
Parsley 有一些添加自定义错误消息的内置方法。
var specificField = $('input.specific-field').parsley();
# add the error
window.ParsleyUI.addError(specificField, "myCustomError", 'this is a custom error message');
# remove the error
window.ParsleyUI.removeError(specificField, "myCustomError");

This is how I got it working for Parsley 2.8:
这就是我让它为 Parsley 2.8 工作的方式：
field.parsley().removeError('customValidationId');
field.parsley().addError('customValidationId', {message: "myCustomError"});

Here is a turnkey-solution that I used for showing error from AJAX to fields identified by their id:
这是我用来显示从 AJAX 到由其 ID 标识的字段的错误的交钥匙解决方案：
// Removing errors from previous AJAX call
if ($('.js_error').length) {
$('.js_error').parsley().removeError('myError');
$('.js_error').removeClass('.js_error');
}
// Showing errors from current AJAX call
for (var idField in ajaxErrors) {
var msg = ajaxErrors[idField];
var field = $('#field_' + idField);
if (field.length) {
field.addClass('js_error');
field.parsley().removeError('myError');
field.parsley().addError('myError', {message: msg});
}
}
This solution will not prevent form-submit, though (because it only displays error messages in the UI, the form validation logic is not touched). That's why Parsley.js favors custom validators.
但是，此解决方案不会阻止表单提交（因为它仅在 UI 中显示错误消息，不会触及表单验证逻辑）。这就是Parsley.js 偏爱自定义验证器的原因。

maybe this:
也许这个：
$('input.specific-field').parsley().UI.manageError({error: 'this is a custom error message'});

Examples above appear to be for Parsley 2.0 I'm stuck with an older version but got custom errors to work with the following.
上面的示例似乎适用于 Parsley 2.0 我坚持使用旧版本但遇到自定义错误以使用以下内容。
el = $('#my_input').parsley();
el.manageErrorContainer(); // set up the error list container
$(el.ulError).empty() // clear any previous errors if you want..
el.addError({error: 'Hey, mind yerself!'});
