Mouse events. [3] [4] Keyboard events. HTML frame/object events. HTML form events. User interface events. Mutation events (notification of any changes to the structure of a document). Progress events [5] (used by XMLHttpRequest and File API [6]). Note that the event classification above is not exactly the same as W3C's classification.
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.
The following code, which works in any compliant player, creates a text field at depth 0, at position (0, 0) on the screen (measured in pixels), that is 100 pixels wide and high. Then the text parameter is set to the " Hello, world " string , and it is automatically displayed in the player:
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 ...
The user can be the source of an event. The user may interact with the software through the computer's peripherals—for example, by typing on a keyboard or clicking with a mouse. Another source is a hardware device such as a timer. Software can also trigger its own set of events into the event loop, such as by communicating the completion of a ...

The event assignment and the event callback function definition are done in a single step in a single location in the code. jQuery also aims to incorporate other highly used JavaScript functionality (e.g. fade ins and fade outs when hiding elements, animations by manipulating CSS properties). The principles of developing with jQuery are:
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 ...
