Description
The onchange event occurs when the value of an HTML element is changed.
Tip: This event is similar to the oninput event. The difference is that the oninput event occurs immediately after the value of an element has changed, while onchange occurs when the element loses focus, after the content has been changed. The other difference is that the onchange event also works on <select> elements.
Syntax
In JavaScript, using the addEventListener() method:
object.addEventListener("change", myScript);
