How to implement an input mask for a cadastral number?

Question

JavaScript

You need to implement an input mask for the cadastral number. You can read more about the cadastral number by clicking on the link . In short, the cadastral number is described by the following regular expression: /\d{2}:\d{2}:\d{1,7}:\d{1,}/ .
For me personally, the difficulty lies in the fact that the last two parts, separated by a colon, are dynamic, and so far I have no idea how to implement all this.

Answer 1

Make 4 inputs separated by colons. When entering the next character, check if a colon is entered. If it's a colon, cancel the input and move the focus to the next input.

Answer 2

I don’t want to know what this number is)) but for customizing inputs it ’s convenient

Answer 3

What do you mean by "dynamic"? different number of digits allowed?
