Attaches two event handlers to the hover event: keydown() Attaches/Triggers the keydown event: keypress() Attaches/Triggers the keypress event: keyup() Attaches/Triggers the keyup event: live() Removed in version 1.9.

Binding Multiple Event Handlers Working with Events in

  1. Use .on () to attach event handlers. Users of older versions of jQuery should use .delegate () in preference to .live ().

This is being handled in jQuery by using .split( ) and then iterating over the list to set the eventListeners for each types. // Add elem as a property of the handle function // This is to prevent a memory leak with non-native events in IE. eventHandle.elem = elem; // Handle multiple events separated by a space // jQuery(...).bind(mouseover mouseout, fn); types = types.split( ); var type, i = 0.
  6. The on () method attaches one or more event handlers for the selected elements and child elements. As of jQuery version 1.7, the on () method is the new replacement for the bind (), live () and delegate () methods. This method brings a lot of consistency to the API, and we recommend that you use this method, as it simplifies the jQuery code base

The two main pros of event delegation over binding directly to an element (or set of elements) are performance and the aforementioned event bubbling. Imagine having a large table of 1,000 cells and binding to an event for each cell. That's 1,000 separate event handlers that the browser has to attach, even if they're all mapped to the same function. Instead of binding to each individual cell though, we could instead use delegation to listen for events that occur on the parent table. event: Required. Specifies one or more events or namespaces to remove from the selected element(s). Multiple event values are separated by a space. Must be a valid event: selector: Optional.
