如何使用jQuery.validator占位符来自定义错误消息? [英] How to customize error message using jQuery.validator placeholders?

问题描述

我正在尝试添加自定义表单验证器.而且我遇到了消息自定义问题.

I'm trying to add custom form validators. And I'm stuck with message customizing issue.

比方说，我想检查字段值是否未超过最大允许值. 我知道验证插件"已经有一个最大"验证器-这仅用于示例:

Let's say I want to check if field value does not exceeds max allowed value. I know that 'Validation Plugin' has a "max" validator already - this is just for sample:

$.validator.addMethod("max-numeric", function(value, element, param) {
    var maxValue = $(element).attr("data-max");
    return (!maxValue) || maxValue >= value;
}, $.validator.format('Applicants must be older than {0} and younger than {1} years of age'));

$("#data-form").validate({
    rules: {
        "form.params1.p4":
        {
            "min-numeric": [5, 6]
        }
    }
});

我无法理解负责替换$ .validator.format中的{0}和{1}的原因.以及如何传递这些参数?

I cannot comprehend what is responsible for replacing {0} and {1} in '$.validator.format'. And how to pass those parameters?

更新:

这是我收到的消息:

申请人的年龄必须大于真实年龄，小于[对象 HTMLInputElement]岁

Applicants must be older than true and younger than [object HTMLInputElement] years of age

我无法理解负责替换'$.validator.format'中的{0}和{1}的原因.以及如何传递这些参数?

I cannot comprehend what is responsible for replacing {0} and {1} in '$.validator.format'. And how to pass those parameters?

在上面的示例中，{0}代表第一个参数，{1}代表第二个参数.参数分别为[5, 6]，并且消息中的此类自动替换由插件自动处理.

In your example above, {0} represents the first parameter and {1} represents the second parameter. The parameters are [5, 6] respectively and the automatic replacement of such within the message is handled automatically by the plugin.

因此，编写自定义方法时，您不需要做任何特别的事情.如果您将三个参数传递给您的方法...

So when writing a custom method, there is nothing special you'll need to do. If you pass three parameters into your method...

customMethod: [34, 50, 10]

...然后您将具有用于自定义消息的{0}，{1}和{2}，分别代表参数的每个值.

...then you'll have {0}, {1}, and {2} available for your custom message, representing each value of the parameters respectively.

它可以正常工作.

如果出了什么问题，那么除了:

If there is something going wrong, then it's not obvious from your OP aside from:

该方法称为max-numeric，但是您要在.validate()方法的rules对象中引用min-numeric.

The method is called max-numeric, but you're referencing min-numeric in the rules object of the .validate() method.

只要在max-numeric旁边有两个参数，示例就可以工作.

As long as you have two parameters next to max-numeric, then your example would work.

max-numeric: [5, 6]
