'''DOM (Document Object Model) Events''' are a signal that something has occurred, or is occurring, and can be triggered by user interactions or by the browser.<ref>{{Cite web|title=DOM Standard|url=https://dom.spec.whatwg.org/#action-versus-occurance|access-date=2021-05-25|website=dom.spec.whatwg.org}}</ref> [[Client-side]] scripting languages like [[JavaScript]], [[JScript]], [[VBScript]], and [[Java (programming language)|Java]] can register various [[Event (computing)#Event handler|event handlers]] or [[Event (computing)|listeners]] on the element nodes inside a [[Document Object Model|DOM]] tree, such as in [[HTML]], [[XHTML]], [[XUL]], and [[Scalable Vector Graphics|SVG]] documents.

Examples of DOM Events:

* When a user clicks the mouse
* When a web page has loaded
* When an image has been loaded
* When the mouse moves over an element
* When an input field is changed
* When an HTML form is submitted
* When a user presses a key<ref>{{Cite web|url=https://www.w3schools.com/js/js_htmldom_events.asp|title=JavaScript DOM Events|website=www.w3schools.com|access-date=2019-08-03}}</ref>

Historically, like DOM, the event models used by various [[web browser]]s had some significant differences which caused compatibility problems. To combat this, the event model was standardized by the [[World Wide Web Consortium]] (W3C) in DOM Level 2.
