Project 2 Form Validation Due Apr 23instructionsproject 2 Form Val
This project involves creating a comprehensive registration form using HTML5 and JavaScript, emphasizing client-side validation. Users will fill out personal details, contact information, and preferences. Validation ensures all data is correctly formatted, complete, and error-free. The form will prevent submission if errors exist, displaying appropriate messages for correction. Additionally, the form should be hosted online, validated using W3C tools, and accompanied by a reflection on the development process.
Paper For Above instruction
The purpose of this project is to construct an HTML5 registration form integrated with JavaScript validation to ensure the accurate capture of user data. Client-side validation enhances user experience by providing immediate feedback, minimizing server load, and ensuring data consistency. The form must include various input fields, each with specific validation requirements, and incorporate dynamic behaviors such as default text handling and error messaging. This comprehensive approach to form validation aligns with best web development practices, emphasizing usability and data integrity.
Design and Structure of the Form
The form design involves multiple sections, each carefully crafted to collect specific data points. The first section gathers user names, requiring both first and last names to be alphabetic, not blank, and with default placeholder texts that disappear upon focusing. The address section includes fields for city, state, and zip code, where city input must be alphabetic and zip code exactly five digits. The state is selected from a dropdown menu, ensuring a valid selection. These validations prevent incorrect address formatting.
Contact details encompass a phone number divided into area code (three digits) and primary number (seven digits), both validated for correct length and numeric content. The email section requires a valid email format, validated with regex or pattern matching, and a confirmation field to cross-check input accuracy. If the email format is invalid, an error message prompts correction.
The user is then prompted to choose a meal preference via radio buttons, enforcing a selection among the options: Vegan, Vegetarian, Non-Vegetarian. The contact method selection requires at least two methods from a set of four options, with validation to prevent insufficient choices. Comments allow optional input with a limit of 250 characters.
Implementation Details
JavaScript functions are employed to validate each input according to the specified rules. These functions are triggered upon form submission, preventing final submission if errors are found. Error messages are displayed adjacent to the respective fields for user correction. The submit function aggregates all validations and, if successful, would email the data (though actual email functionality may be simulated or performed server-side). The reset button clears all fields, restoring the default state.
Advanced Challenges
Extra features include adding at least two additional validated fields, such as a company name or preferred contact time, and incorporating a logo image at the top of the form for branding purposes. These enhancements improve usability and visual appeal.
Hosting and Validation
The completed form is to be hosted on the Nova server, ensuring accessibility. The HTML should be validated with W3C to confirm error-free markup. Proper hosting URLs must be provided with submission.
Reflection
Students should reflect on challenges encountered, such as complex validation logic, handling default text, or managing multiple validation conditions simultaneously. The reflection should also detail whether the advanced tasks were completed, describing the additional features implemented.
Submission
Submit the hosted URL, all code files, and the reflection document through the designated assignment folder before the deadline. Ensure proper commenting within code, and verify the correctness of submission. Late penalties apply, and extensions require official documentation.
