A10: Regular Expressions

On This Page Overview Specifications Extra Credit Grading Criteria (20) What to Turn In Overview The main points of this assignment are to: Validate form information Use regular expressions ^ top Specifications Tutorial Exercises Complete the in-chapter tutorial exercises (step-by-step instructions to complete the case study) that are listed throughout chapter Tutorial 7.3. You must follow the steps exactly and turn in all the files to make it work correctly. This does NOT include the Review Assignment nor any Case Problems at the end of the chapter. Form and Form Validation For this project, you will update your single page form from the last assignment to validate form data using regular expressions. The updates are shown in emphasis font. Call your page the same name as before: form.html. Remember that your form must collect the following information: Buyer's first and last name Street address City State Zip code Telephone number Credit card type (use those shown in the tutorial case) Credit card number Credit card expiration with month and year fields In addition, the form must show a subtotal for the order in the amount of $50.00 Also, the form must allow the user to select one of the following shipping options: Federal Express ($10.00) UPS ($8.50) USPS ($6.75) Once the user selects the shipping method, 5% tax should be added to the combined amount for the subtotal and shipping and displayed to the user. Include the following validation before the form is submitted: Buyer's first and last name are 50 characters or less Street address is 6 characters or more City is 2 characters or more State is exactly 2 letters (not just characters) ZIP code is 0, 5 or 9 (5-4) digits (no letters or non-digit characters allowed) Credit card is between 13 and 16 digits long (including 13 and 16) with blank spaces removed and validated using the Luhn formula Credit card expiration is a valid date not more than 10 years in the future Shipping method is selected Note you do not need to use JavaScript for validation if your HTML form ensures a correct value. For example, using a selection list for the state would preclude the need to validate the state, assuming that all the selection list option values are exactly two characters. However, your selection list must allow all valid entries (see state abbreviations). You must use regular expressions in the validation process for the ZIP code and credit card number. In addition to validating the form, send the form information to a page named receipt.html and display at least the following data from the form: Buyer's first and last name Total order amount (including tax and shipping) Be sure to put your JavaScript code for the form in various functions, and to place at least one function in a file named form.js. Once you complete this page, test your JavaScript to ensure it works without error. Other Specifications Complete a README.txt file following the instructions for homework. Zip your files and submit the zipped archive file to WebCT as explained in the section of this document: What to Turn In. Hints To verify your credit card validation, you can use the test numbers found here ^ top Extra Credit This extra credit is worth 2 points. Complete Case Problem 2 of Tutorial 7 that starts on page JVS 406 of your textbook. Include the extra credit solution in your assignment zip file. Make certain that your README.txt file lists any extra credit attempted. ^ top Grading Criteria The instructor will evaluate your assignment using the following criteria. Each criteria represents a specific achievement of your assignment and has a scoring guide. The scoring guide explains the possible scores you can receive. Some scoring guides have a list of indicators. These indicators are a sign of meeting, or a symptom of not meeting, the specific criterion. Note that a single indicator may not always be reliable or appropriate in a given context. However, as a group, they show the condition of meeting the criterion. For information on grading policies, including interpretation of scores, see the course information page.
