What challenges did you encounter, and how did you overcome them?

I haven't got much experience with form validation, so the validation was sort of a challenge for me. I struggled with the error message because the :invalid pseudo selector gave the error message when the user was typing in the email address. That was not the experience I wanted to create so I fixed the problem with JavaScript. I'm not sure if this is the correct way to handle form validation, so any advice is welcome.

What specific areas of your project would you like help with?

Correct ways of form validation.

    Hi!

    There are a few ways to validate input field via JS. For example, you can check the value every time when it's changing with the input event. This event triggers every time user types something, but that is not a very popular method cos it's could be annoying to get error message before you write all what you want.

    Alternative way is to use change or focusout events. Those events both triggers when input loose focus, but change works only if it's value were changed.

    Than you need to validate input's value. The easiest way to do it by using regular expressions. For now I use this one - /[-.\w]+@([\w-]+\.)+[-\w]/g, but I need to improve it cos it's not validate numbers.

    Also I recommend you to learn about special JS object FormData and use it to collect data from forms. This object is quite useful when you need to send data to the server, so It is a good habit for the future projects.

    Oh, and I was recently wondered about accessibility issues which occurs when we are using custom error messages and I found this article.

    I hope something of this could be helpful =)
