[英]How to customize error message using jQuery.validator placeholders?
I'm trying to add custom form validators. 我正在尝试添加自定义表单验证器。 And I'm stuck with message customizing issue.
而且我遇到了消息自定义问题。
Let's say I want to check if field value does not exceeds max allowed value. 假设我要检查字段值是否未超过最大允许值。 I know that 'Validation Plugin' has a "max" validator already - this is just for sample:
我知道“验证插件”已经具有“最大”验证器-这仅用于示例:
$.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'));
$("#data-form").validate({
rules: {
"form.params1.p4":
{
"min-numeric": [5, 6]
}
}
});
I cannot comprehend what is responsible for replacing {0} and {1} in '$.validator.format'. 我无法理解是什么负责替换$ .validator.format中的{0}和{1}。 And how to pass those parameters?
以及如何传递这些参数?
UPDATE: 更新:
Here is the message I get: 这是我收到的消息:
Applicants must be older than true and younger than [object HTMLInputElement] years of age
申请人必须大于真实年龄且小于[object HTMLInputElement]岁
I cannot comprehend what is responsible for replacing
{0}
and{1}
in'$.validator.format'
.我无法理解是什么负责替换
'$.validator.format'
{0}
和{1}
。 And how to pass those parameters?以及如何传递这些参数?
In your example above, {0}
represents the first parameter and {1}
represents the second parameter. 在上面的示例中,
{0}
代表第一个参数, {1}
代表第二个参数。 The parameters are [5, 6]
respectively and the automatic replacement of such within the message is handled automatically by the plugin. 参数分别为
[5, 6]
,消息中的此类自动替换由插件自动处理。
So when writing a custom method, there is nothing special you'll need to do. 因此,编写自定义方法时,您不需要做任何特别的事情。 If you pass three parameters into your method...
如果您将三个参数传递给方法...
customMethod: [34, 50, 10]
...then you'll have {0}
, {1}
, and {2}
available for your custom message, representing each value of the parameters respectively. ...那么您将获得
{0}
, {1}
和{2}
的自定义消息,分别代表参数的每个值。
It just works. 它只是工作。
If there is something going wrong, then it's not obvious from your OP aside from: 如果出了什么问题,除了以下几点,从您的OP中看不出来:
The method is called
max-numeric
, but you're referencingmin-numeric
in the rules object of the.validate()
method.该方法称为
max-numeric
,但是您要在.validate()
方法的rules对象中引用min-numeric
。
As long as you have two parameters next to max-numeric
, then your example would work. 只要在
max-numeric
旁边有两个参数,您的示例就可以工作。
max-numeric: [5, 6]
