IT3215 Introduction to JavaScript

Unit 4 Assignment

Form Field Validation and Error Messages

Overview

You have created a basic form and added interactivity to images using JavaScript. Now it is time to validate information entered into your form fields. You will use the "registration.html" file found in your Zip file. You will see that the page has a form with the following fields to allow users to register for an account. The items in parentheses are defined formatting instructions to be observed for each field.

Username* (must only contain letters and numbers)

Password* (minimum of 8 characters)

PasswordVerify* (minimum of 8 characters, must match password)

FirstName* (text string)

LastName* (text string)

Email (uses xxx@xxx.xxx format)

PhoneNumber (uses (xxx) xxx-xxxx format)

SignUpNewsletter (radio box for yes/no)

Tips:

JavaScript is case sensitive, so a variable named myVar is different from MyVar and myvar.

Perform your form validation testing as you go rather than all at the end. It will be much easier to fix the error if you have a smaller sequence of code to review.

Directions

Read the assignment overview.

Use the registration.html file to add functionality to the form found on the page. The JavaScript that you write should validate each field and, if errors are made, display appropriate error messages that direct the user to complete the form properly. Once the form is completed, your script should open the confirmation page (confirmation.php).

Note: The input fields in the form with an asterisk are required fields.

Make sure to do the following:

Write JavaScript that defines that a field is required and generates an appropriate error message if the field has not been completed.

Write JavaScript to validate all input fields per the formatting definitions that the field values should be checked against (found in the overview) after each field.

Write JavaScript that displays an appropriate error correction message (next to the field) in the event a form entry error has been made.

Write a JavaScript that will default the user’s cursor to the first erroneous input field in the event that there is an input error.

Create a submit button that executes the validation when submitted.

Once completed, view your pages in each of your two selected Web browsers to see if the content renders appropriately and consistently within each. Next, verify that your code is error free using the appropriate browser specific development tool found in the Resources.

Take a screen capture of each of your validation results and save it for submission.

Example assignments: You may use the assignment examples, linked in the Resources, to give you an idea of what a Proficient or higher rating on the scoring guide would look like.

Submission Requirements

Upload your Web site files to your Web host.

Submit your work in the courseroom using a single Zip file containing the following:

Your entire Web site and all associated files.

A Word document with:

The URL to your Web site so the instructor can view your site on a live host.

A screen capture of each of your two validations that you completed using the developer tools found in the Resources.
