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

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.

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]

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

It just works.

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

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

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

max-numeric: [5, 6]
