Question

What is the difference between the onFocus and onMouseEnter event?

Answer 1

onFocus, when applied to form elements, is triggered when the field is given focus by either tabbing to the field or clicking on it so you can enter a value. Most HTML elements are not given focus through onMouseEnter in any case, so the two events are completely different.

Answer 2

You get the onMouseEnter when the mouse just hovers over the object. You can also get focus with the keyboard by tabbing to the control or programatically.

Answer 3

The onfocus event fires when the user clicks on an element, usually <input> or <textarea> elements, and the mousover event fires when the pointer mouses over any element on the page. The mouseenter event, however, is a non-standard event used by IE and implemented by some javascript libraries.
