Appends an event handler to an element. The shorthand version on is equivalent. Typically you will +use Ext.core.Element.addListener directly on an Element in favor of calling this version.

+

Parameters

  • el : String/HTMLElement

    The html element or id to assign the event handler to.

    +
  • eventName : String

    The name of the event to listen for.

    +
  • handler : Function

    The handler function the event invokes. This function is passed +the following parameters:

      +
    • evt : EventObject
      The EventObject describing the event.
      • +
    • t : Element
      The Element which was the target of the event. +Note that this may be filtered by using the delegate option.
      • +
    • o : Object
      The options object from the addListener call.
      • +

    +
  • scope : Object

    (optional) The scope (this reference) in which the handler function is executed. Defaults to the Element.

    +
  • options : Object

    (optional) An object containing handler configuration properties. +This may contain any of the following properties:

      +
    • scope : Object
      The scope (this reference) in which the handler function is executed. Defaults to the Element.
      • +
    • delegate : String
      A simple selector to filter the target or look for a descendant of the target
      • +
    • stopEvent : Boolean
      True to stop the event. That is stop propagation, and prevent the default action.
      • +
    • preventDefault : Boolean
      True to prevent the default action
      • +
    • stopPropagation : Boolean
      True to prevent event propagation
      • +
    • normalized : Boolean
      False to pass a browser event to the handler function instead of an Ext.EventObject
      • +
    • delay : Number
      The number of milliseconds to delay the invocation of the handler after te event fires.
      • +
    • single : Boolean
      True to add a handler to handle just the next firing of the event, and then remove itself.
      • +
    • buffer : Number
      Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed +by the specified number of milliseconds. If the event fires again within that time, the original +handler is not invoked, but the new handler is scheduled in its place.
      • +
    • target : Element
      Only call the handler if the event was fired on the target Element, not if the event was bubbled up from a child node.
      • +
