Event reference
Events are fired to notify code of «interesting changes» that may affect code execution. These can arise from user interactions such as using a mouse or resizing a window, changes in the state of the underlying environment (e.g. low battery or media events from the operating system), and other causes.
Each event is represented by an object that is based on the Event interface, and may have additional custom fields and/or functions to provide information about what happened. The documentation for every event has a table (near the top) that includes a link to the associated event interface, and other relevant information. A full list of the different event types is given in Event > Interfaces based on Event.
This topic provides an index to the main sorts of events you might be interested in (animation, clipboard, workers etc.) along with the main classes that implement those sorts of events. At the end is a flat list of all documented events.
Note: This page lists many of the most common events you’ll come across on the web. If you are searching for an event that isn’t listed here, try searching for its name, topic area, or associated specification on the rest of MDN.
Event index
Used to respond to changes in animation status (e.g. when an animation starts or ends).
Events related to the fetching data.
Used to notify when content is cut, copied, or pasted.
Events related to composition; entering text «indirectly» (rather than using normal keyboard presses).
For example, text entered via a speech to text engine, or using special key combinations that modify keyboard presses to represent new characters in another language.
Provides notification events when CSS transitions start, stop, are cancelled, etc.
Events related to database operations: opening, closing, transactions, errors, etc.
Events related to modifications to the Document Object Model (DOM) hierarchy and nodes.
Warning: Mutation Events are deprecated. Mutation Observers should be used instead.
Events related to using the HTML Drag and Drop API and wheel events.
Drag and Wheel events are derived from mouse events. While they are fired when using mouse wheel or drag/drop, they may also be used with other appropriate hardware.
Wheel events fired on Document and Element
Events related to elements gaining and losing focus.
Events related to forms being constructed, reset and submitted.
Used to notify when the transitioning between full screen and windowed modes, and also of errors occurring during this transition.
Touch events are recommended for implementing gestures.
In addition there are a number of non-standard gesture events:
Events related to changing the state of a display or textual element.
Events related to HTML input elements e.g. , , or .
Events related to using a keyboard.
Used to notify when keys are moved up, down, or just pressed.
Events related to loading and unloading documents.
Events related to installation of progressive web app manifests.
Events related to a window receiving a message from another browsing context.
Events related to using a computer mouse.
Used to notify when the mouse is clicked, doubleclicked, up and down events, right-click, movement in and out of an element, text selection, etc.
Pointer events provide a hardware-agnostic alternative to mouse events. Drag and Wheel events are derived from mouse events.
Events related to gaining and losing network connection.
Provides hardware-agnostic notification from pointing devices including Mouse, Touch, pen/stylus.
Events related to printing.
Events sent to the global script context when any JavaScript promise is rejected.
Events related to SVG images.
Selection API events related to selecting text.
Provides notification events from interacting with a touch sensitive screen (i.e. using a finger or stylus). Not related to the Force Touch API.
Warning: The WebVR API (and associated Window events) are deprecated.
Used to respond to new messages and message sending errors. Service workers can also be notified of other events, including push notifications, users clicking on displayed notifications, that push subscription has been invalidated, deletion of items from the content index, etc.
