There is a huge collection of events that can be generated by most element nodes: Mouse events. [3] [4]Keyboard events.; HTML frame/object events. HTML form events. User interface events.
The actual logic is contained in event-handler routines. These routines handle the events to which the main program will respond. For example, a single left-button mouse-click on a command button in a GUI program may trigger a routine that will open another window, save data to a database or exit the application.
Event bubbling is a type of DOM event propagation [1] where the event first triggers on the innermost target element, and then successively triggers on the ancestors (parents) of the target element in the same nesting hierarchy till it reaches the outermost DOM element or document object [2] (Provided the handler is initialized). It is one way ...
The DOM also provides access to user actions such as pressing a key and clicking the mouse. It is possible to intercept and process these and other events by creating event handler functions and routines. The event handler receives control each time a given event occurs and can carry out any appropriate action, including using the DOM to change ...
JavaScript event listeners help developers run code when specific events happen. The onmouseover event listener runs code when a user's mouse pointer enters an element. The onmouseout event listener runs code when the mouse pointer leaves that element. These events can be added to HTML elements to make very interactive web pages.
Even when synchronous handling appears to block execution, the underlying mechanism in many systems is still asynchronous, managed by the event loop. [ 1 ] [ 2 ] Events can be implemented through various mechanisms such as callbacks, message objects, signals, or interrupts, and events themselves are distinct from the implementation mechanisms used.
