Explanation

HTML Structure:

We have links with the class donation-link and a data-amount attribute that stores the value to be set.

The text input with the ID donation-amount that will display the chosen donation amount.

JavaScript Logic:

The script waits until the DOM content is fully loaded before executing.

It selects all elements with the class donation-link and the input field donation-amount.

For each donation link, a click event listener is added.

When a donation link is clicked, the default action (navigating to a URL) is prevented.

The donation amount is then retrieved from the clicked link's data-amount attribute and used to set the value of the text input field.

By following these steps, you can enhance your donation form to allow users to quickly select an amount by clicking a link, providing a seamless and friendly user experience.
