Coding Challenge: Simple Event Registration Portal

Objective: Create a simple event registration portal using only HTML and JavaScript. This portal will enable users to register for an event by providing their personal details, selecting an event date, and submitting their preferences. Upon submission, the registration details should be displayed on the same page, showcasing a simplistic approach without any CSS styling.

Requirements:

Task 1: Setup

• Create an HTML File: Start by creating an index.html file. This file will serve as the foundation for your event registration form and include the script linking.

Task 2: Create the Registration Form

• Form Structure: Within index.html, insert a
  element with the following inputs:

  • A text input for the registrant's name.
  • A text input for the registrant's email address.
  • A dropdown selection for the registrant to choose an event date.
  • A checkbox group for selecting preferences (e.g., Meal Preference: Vegetarian, Non-Vegetarian, Vegan).
  • A submit button to finalize the registration.
• Registration Display Area: Add a
  element below the form to display the submitted registration details.

Task 3: Implement Form Submission and Validation

• JavaScript Logic: Create a script.js file for:
  • Preventing the default form submission action.
  • Validating that all form fields are filled out. Display an alert if any field is missing.
  • Appending the registration details to the display area upon submission.

Task 4: Display Registration Details

• Details Display: After form submission, dynamically create and append elements within the registration display area to show the registrant's name, email, selected event date, and preferences.
