Set Fixed length of input text

Question

I want to set the input length of a textbox to 9 characters only. No more, no less. Is there any way to do it? Any help would be very much appreciated. Thanks!

Answer 1

With HTML5 you can use the pattern attribute to do this:

<input type="text" pattern=".{9}" required name="patternTest" title="Field must be 9 characters long" />
