instructions

  • Open and Save HTML File

    • Open the Laboratory2.html file and save it as Laboratory6.html.

  • Create the Form

    • Within the <body> of the file, create a <form> element with the following attributes: action: Set to submit_form.php method: Set to post onsubmit: Set to validateForm(event)

  • Edit HTML Form

    • Remove all required attributes from the form elements to customize the display message.

  • Enhance the Form with JavaScript Validation

    • Implement JavaScript to validate the form data before submission.

Ensure that:

All required fields are properly validated.

Appropriate error messages are shown for invalid inputs using the alert method for the following:

Ø First andLast Name: "Please enterboth your first and last name"

Ø Email: "Please enter your email"

Ø Date of Birth: "Please select your date of birth"

Ø Gender: "Please select your gender"

Ø Address: "Please enter your address"

Ø Country: "Please select your country"

Ø Terms: "You must agree to the terms and conditions"

  • Confirmation Dialog
    • After the user clicks the submit button, a confirmation dialog should appear asking: "Are you sure you want to submit?"
    • Use the confirm method for the confirmation dialog. If the user clicks "OK", display a message saying, "Successfully Submitted". If the user clicks "Cancel", return to the previous page to allow further editing.
