This function attaches an event to an object. For example, you can attach a “click” event to a button. The same can be accomplished by assigning the onclick property on a button; however, with the addEvent() function, you can attach multiple unrelated “click” events to the same object.
- obj – the object or element to which the event will be applied
- eventName – the event name. Example: “click”, “mouseover”, etc.
- func – the event handler function
The following code assigns an event to a button.
Alternatively, an anonymous function can be used when assigning the event.
