Deprecated
This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Avoid using it and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
The Event.initEvent() method is used to initialize the value of an event created using Document.createEvent().
Events initialized in this way must have been created with the Document.createEvent() method. This method must be called to set the event before it is dispatched, using EventTarget.dispatchEvent(). Once dispatched, it doesn't do anything anymore.
Do not use this method anymore as it is deprecated.
Instead use specific event constructors, like Event(). The page on Creating and triggering events gives more information about the way to use these.
Syntax
event.initEvent(type, bubbles, cancelable);
type- Is a
DOMStringdefining the type of event. bubbles- Is a
Booleandeciding whether the event should bubble up through the event chain or not. Once set, the read-only propertyEvent.bubbleswill give its value. cancelable- Is a
Booleandefining whether the event can be canceled. Once set, the read-only propertyEvent.cancelablewill give its value.
Example
// Create the event. var event = document.createEvent('Event');// Create a click event that bubbles up and // cannot be canceledevent.initEvent('click', true, false); // Listen for the event. elem.addEventListener('click', function (e) { // e.target matches elem }, false); elem.dispatchEvent(event);

[1] Before Firefox 17, a call to this method after the dispatching of the event raised an exception instead of doing nothing.
