Make a copy of the order form from lab exercise 4 and name it l6p3.php. Remove the JavaScript code to calculate the total price. Add JavaScript code to produce an error message and suppress submission of the form if any quantity field contains non-numeric data. (It's OK for a quantity to be empty, but if it's non-empty, it must have only numbers.) Add an action= attribute to your tag to submit the form to http://weblab.kennesaw.edu/formtest.php. Test that the form is submitted correctly when the quantities are numeric or empty, and that an error message is produced otherwise. (Regular expressions are your friend. Anything that's not a digit is bad. What is the predefined class for non-digits?)
