Q & A

What is the purpose of using the `<input type='url'>` element in HTML?

The `<input type='url'>` element is used to create a form input field specifically for URL entry. It ensures that users can only submit valid URLs by performing automatic validation on the entered data.

What happens if the user enters an incorrect URL format in the URL input field?

If the user enters an incorrect URL format, such as missing the protocol (`http://`), the browser triggers a validation warning and prevents the form from being submitted.

How can the user test the URL input validation in the form?

To test the validation, the user can enter a URL without the proper format, such as `kelas komputer online`. The browser will show a validation warning. A valid URL, like `http://example.com`, will pass the validation.

What is the role of the `name` attribute in the URL input element?

The `name` attribute is used to specify a name for the input field, which is essential for accessing the input data when the form is submitted.

What is the correct format for a valid URL input in the `<input type='url'>` field?

A valid URL must include the protocol (e.g., `http://` or `https://`), followed by the domain (e.g., `example.com`). For example, `http://example.com` is a valid URL.

Can the user submit the form with a non-URL value in the URL input field?

No, the form cannot be submitted if the value entered in the URL input field is not a valid URL. The field enforces validation that only allows proper URL formats.

What is the significance of the `button` tag in the form?

The `<button>` tag is used to create a submit button that triggers the form submission. In this case, it is used to test the validity of the URL input before sending the data.

How does the browser handle incorrect URL inputs in the form?

The browser displays a validation warning when the entered URL does not match the required format, preventing the form from being submitted until a valid URL is provided.

What is the expected outcome when a valid URL is entered in the input field?

When a valid URL, such as `http://example.com`, is entered, the validation warning disappears, and the form can be successfully submitted.

What key benefit does the `type='url'` input element offer for form users?

The key benefit of using `type='url'` is that it automatically validates the format of the entered URL, ensuring users submit URLs in the correct format and preventing errors during form submission.
