  • A textarea gives you a great opportunity to allow people to place large amounts of text as input in a form. There are a number of ways to limit the amount that is sent, but not to many that will let you see how much you may have exceeded maximum or minimum input lengths prior to submitting the entire form. The following example will display the number of characters typed into a textarea field. It works the same way for a text input field.
