I have been doing quite a bit of web page front-end work lately. jQuery is often used to handle interactive front-end implementation.
One of tasks I did was to highlight the div box background color when mouse hovers on it. So I tried to use jQuery to do so. But the child element (inner box) of the div box could not change the background color since I used “mouseenter” to handle the mouse hovering event.
After I did some research about mouseover and mouseenter, I realized that mouseover fires event even if mouse is pointed to the child element of the outer box. If the div box does not have any child element, then mouseover and mouseenter will behave exactly the same.
I also found an excellent article talking about the difference between mouseout and mouseleave.
