- /**
- * @class Ext.EventObject
- Just as {@link Ext.Element} wraps around a native DOM node, Ext.EventObject
- wraps the browser's native event-object normalizing cross-browser differences,
- such as which mouse button is clicked, keys pressed, mechanisms to stop
- event-propagation along with a method to prevent default actions from taking place.
- For example:
- function handleClick(e, t){ // e is not a standard event object, it is a Ext.EventObject
- e.preventDefault();
- var target = e.getTarget(); // same as t (the target HTMLElement)
- ...
- }
- var myDiv = {@link Ext#get Ext.get}("myDiv"); // get reference to an {@link Ext.Element}
- myDiv.on( // 'on' is shorthand for addListener
- "click", // perform an action on click of myDiv
- handleClick // reference to the action handler
- );
- // other methods to do the same:
- Ext.EventManager.on("myDiv", 'click', handleClick);
- Ext.EventManager.addListener("myDiv", 'click', handleClick);
