Define a "proper" name.

Start by reading Falsehoods Programmers Believe About Names[^] - particularly points 15 (People’s names do not contain numbers) and 17 (People’s names are not written in all lower case letters).

Makes no sense: any string can be called "name". Before requiring anything, require yourself to understand what you want.

Do you only want names that sudevsu approves of? Does your client/employer know this? Maybe you just want to create a bad experience for your users?

You can try easier techniques like tabindex and validations for the input controls to control this type of interactions.

But if you absolutely have to enforce a set sequence of activities, you could use a JavaScript/jQuery type function that does a validation on the values of the controls in the sequence you like and then if any control has an empty value, set the focus on that control and exits the function.

This function could be triggered on tab out events for the controls and on page load event for the page.
