I am fairly new to JQuery API. I have been using mouseover, but I have never used hover before. SO I am wondering if I should use hover instead.

I have a 2.67 GHz Celeron processor, 1.21 GB of RAM on a x86 Windows XP Professional machine. My understanding is that the Android emulator should start fairly quickly on such a machine, but for me it does not. I have followed all instructions in setting up the IDE, SDKs, JDKs and such and have had some success in staring the emulator quickly but is very particulary. How can I, if possible, fix this problem?
Well, .hover() binds two handlers for the events mouseenter and mouseleave, so it is a more convenient way and also easier to understand the purpose.
ReplyDeletemouseenter differs from mouseover so far as mouseenter is not fired if the cursor is over/enters a child element of the element the handler is bound to.
It is only fired once, when the cursors enters the element. mouseover is always fired, even if the cursor is over a child element.
The best way to see the difference is to have a look at the example of mouseleave().
Furthermore, mouseover and mouseout are real JavaScript events whereas mouseenter and mouseleave are events provided by jQuery (afaik).
In the end, it depends on what you want to achieve. There is no right or wrong and all these methods have their purpose. Unless you show some code, there is not much more to say.
If you mean :hover in CSS and you can achieve the desired effect with it, go for it. If there is a non-JS solution for a certain problem, always choose this one.
hover just saves you from having to do both a mouseenter and a mouseleave by doing both in one function.
ReplyDeletei prefer use css hover, because seems that I write less code to do the same.
ReplyDeleteThey're the same, except hover handles both mouseenter and mouseleave

So you can use it like this
$('selector').hover(function () {
// Do stuff on mouse enter
}, function () {
// Do other stuff on mouse leave
}
)
Since you are learning, here is another equivalent to using hover:
ReplyDelete$('selector').bind('mouseenter mouseleave', function(){
if (event.type == "mouseenter") {
// MouseEnter code
} else {
// MouseLeave code
}
})
