Fixes #579: Resolved entering date issue

[byteom]

Fixes #579

Summary of Changes:

• Issue: Users were able to enter more than four digits for the year in the "Date of Journey" field, resulting in an invalid date format On this page - https://ticket-booking-blue.vercel.app/buy.html.

• Fix: Implemented restrictions to ensure the year part of the date input does not exceed four digits.

Changes Made:

1. JavaScript Validation:

   • Added a validation script to enforce strict date input. The script checks that the date entered follows the YYYY-MM-DD format and restricts any input beyond 10 characters, preventing users from entering more than four digits for the year.

   document.getElementById('journeyDate').addEventListener('input', function() {
       const datePattern = /^\d{4}-\d{2}-\d{2}$/;
       if (!datePattern.test(this.value)) {
           this.value = this.value.slice(0, 10); // Restrict to the YYYY-MM-DD format
       }
   });

2. Html code Updation:

• specify a max attribute in the input[type="date"] field to limit the possible year range

     <div class="form-group">
  <label for="journeyDate">Date of Journey</label>
  <input type="date" id="journeyDate" name="journeyDate" required max="9999-12-31">
</div>
