Building a Phone Number Input the Right Way

The right way

Now, how would we build a phone number input the right way? A good form input should:

• Clearly show what sort of format is recommended.

• Accept all kinds of formats, regardless of whether they’re pasted, typed, or entered through the browser’s autofill tool.

• Reformat the phone number in an easy-to-read way if possible.

• Clearly indicate problems when they occur and what needs to be done to fix them.

This is possible using just techniques from the first section of this course.
