jQuery验证器addmethod自定义消息 [英] jquery validator addmethod custom message

问题描述

我为jquery的验证器插件创建了一个方法，该方法的工作原理类似于远程规则.区别在于，我想显示动态错误消息(基于ajax响应).

I've created a method for jquery's validator plugin, that works like the remote rule. The difference is that I'd like to display a dynamic error message (based on the ajax response).

jQuery.validator.addMethod("duplicate", function(value, element, params) { 
    var object_settings = this.settings;
    params.data[$(element).attr("name")] = value;
    $.post(params.url, params.data, function(response) {
        if (response == 'true'){ return true; }
        else {
            object_settings.messages[element.name] = response;
            return false;
        }
    }, 'text');
}, '');

它起作用...它设置消息，但最初不显示它(如果您再次验证该字段，则显示消息).

It works...sort of....it sets the message, but doesn't display it initially (if you validate the field a second time, the message is displayed).

有什么建议吗?

(也许远程规则提供了此功能...我在文档中找不到任何内容)

(maybe the remote rule offers this functionality...I couldn't find anything in the documentation)

推荐答案

这是解决方案....需要调用对象的showErrors函数:

Here's the solution....needed to call the showErrors function of the object:

jQuery.validator.addMethod("duplicate", function(value, element, params) { 
    var validator = this;
    params.data[element.name] = value;
    $.post(params.url, params.data, function(response) {
        if (response == 'true'){ return true; }
        else {
            var errors = {};
            errors[element.name] =  response;
            validator.showErrors(errors);
            return false;
        }
    }, 'text');
}, '');

取自jquery.validate.js中的远程"(第917-919行)

Taken from "remote" in jquery.validate.js (lines 917 - 919)
