As we've seen before, creating re-usable functions can significantly reduce the size of your Java Script code.These functions can even be included from an external javascript file so that the browser can cache them, and so the programmer isn't always copying and pasting.Basically, for each of the regular expression tests, an array is returned holding each component of the pattern that we've matched.

Note: You do not need to do the things mentioned in this article if you have created your feedback form using the Feedback Form Script Wizard.This script only confirms that the input format is correct and that each individual value falls within its allowed range.It does not check for leap years or invalid dates at the end of short months.The expressions use a pre-defined class is returned which enables the form to be submitted.This routine DOES NOT check that the date or time input values are valid, just that they match the required format (d/m/y and h:m). Once you're in control of the input format, it's a lot easier to check that the values are actually valid.

For the time check, the array returned includes the hour (pos 1), minutes (pos 2) and, optionally, the am/pm string (pos 3).
