JavaScript Event--ui Event

Source: Internet
Author: User

The UI usually has the meaning of "interacting with the user," but the UI events of JS are not all related to user actions.

UI events are usually related to windows, and often have the following:

  • Load: When the page is loaded (including all external resources: JS,CSS, images, and so on), the Load event on the window is triggered.
  • Unload: Triggered when the page is completely uninstalled. When a full unload, the element resource for the page no longer exists, so you cannot manipulate access to the page resource in unload.
  • Resize: Triggered when the page height or width changes.
  • Scroll: page scrolling event.
