Quizplus · Accepted Answer

The onbeforeunload event handler is applied to a page when it is about to be unloaded by the browser, such as when the user navigates away from the page or closes the browser tab. This can allow the page to prompt the user with a confirmation message before they leave the page or accidentally lose their data. The other options (onload, onunload, onbeforeload) relate to other stages of the page's load and unload process and do not specifically apply to when the page is about to be unloaded by the browser.
