𝐓𝐡𝐞 𝐜𝐡𝐚𝐧𝐠𝐞 𝐞v𝐞𝐧𝐭 𝐢𝐬 𝐟𝐢𝐫𝐞𝐝 … https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/change_event#wikiArticle ¦ The change event is fired for ,

¦ elements when an alteration to the element's value is committed
   ¦ by the user.

¦ Depending on the kind of element being changed and the way the
   ¦ user interacts with the element, the change event fires at a
   ¦ different moment:

¦ • When the element is :checked (by clicking or using the
   ¦   keyboard) for <input type="radio"> and <input type="checkbox">;

¦ • When the user commits the change explicitly (e.g., by
   ¦   selecting a value from a <select>'s dropdown with a mouse
   ¦   click, by selecting a date from a date picker for <input
   ¦   type="date">, by selecting a file in the file picker for
   ¦   <input type="file">, etc.);

¦ • When the element loses focus after its value was changed, but
   ¦   not commited (e.g., after editing the value of <textarea> or
   ¦   <input type="text">).

¦ The HTML specification lists the <input> types that should fire
   ¦ the change event.
