How to validate address input?

I have address input.
The code must be like this

if the address input is empty then show a text message to input the address. If the address box is filled then enable the button and move to slide[1]

I do not see any code. Did you already tried to code a possible solution ?

Here’s a great example of custom validations which will show you different techniques to achieve what you want.
