Question
Which event is triggered when the user leaves the page?
Chọn đáp án đúng:
onunloadonleaveonunmountonescape
Solution
The correct answer is onunload.
In web development, the onunload event is specifically designed to be triggered when a user leaves a webpage. This can occur for various reasons, such as navigating to a different page, closing the browser tab, or even refreshing the page. Developers often use this event to perform cleanup tasks or to warn users about unsaved changes before they leave the page.
- onleave: This is not a standard DOM event.
- onunmount: While this is used in frameworks like React to indicate that a component is unmounted from the DOM, it does not apply to the entire page lifecycle.
- onescape: This typically refers to keyboard events and does not indicate leaving the page.
Thus, onunload is the event that is correctly associated with a user leaving a webpage.
