fadein/fadeout issue, tried stop but does not work - javascript

So all I want to do is fade out a div and fade in another. When i hover a link i want to fadeout prev div and fade in the proper div. everything works fine unless I hover over the links too fast. when i hover too fast, a div would not get faded out. I have tried using stop(), and tried different combinations of true false on the stop function but nothing works. if i change the fade timer to 0 then it works. the code I have is too much to pasted here but basically it is not a simple fadein/fadeout. I have some other stuff going on before the fade function is called
here is my fade function
var fadeEffect = function (a, b) {
$(a).fadeOut(300, function () {
$(b).fadeIn(300);
});
}
it's a private function inside of an object. I tried using stop() on a and/or b and i still get the same thing. If i change the 300 to 0, it works fine
anyone have any ideas?
simplified version here http://jsfiddle.net/LLMUX/9/

I have updated your JSFiddle -> http://jsfiddle.net/manseuk/LLMUX/11/
What i did was add the stop to the divs that were being animated - that stops the duplicates :
$("#vehicleSelector .vehiclesList").bind({
mouseenter: function(event) {
$('#vehicleSlides div, #promoSlides div').stop(true,true); // stop any running animations
event.stopPropagation();
sControl.timerIsOn = false;
showSecondary(this.id)
},
mouseleave: function(event) {
$('#vehicleSlides div, #promoSlides div').stop(true,true); // stop any running animations
event.stopPropagation();
next();
}
});

CSS transitions playing too many times; Added via jQuery

So I have 2 divs, one of them being hidden on load using jQuery .hide()
One div is id is menus and the other is prix-fix-menu
I want to fade and slide between the 2 with button clicks. Its a restaurant menu, so I want to smoothly scroll to the different sections of the menu (such as apps, entrees, dessert etc.) but then if the user clicks the Prix Fix button, the page will fade and slide out the regular menu and fade and slide in the Prix Fix menu. If they have the Prix Fix menu open, I want any of the links OTHER THAN the Prix Fix link, to take the user back to the main menu page, sliding out the Prix Fix and sliding in the regular menu.
To accomplish this, Im just dynamically adding and removing classes from Animate.css. The problem is that the animations keep playing more than once (even though Im using .one() method) . I believe it may be because Im listening to the animationend event to then play another animation causing a loop. But whats weird is that it plays it exactly 4 times, not infinitely.
Here's the javascript:
$('#prix-fix-menu, #catering-menu').hide();
$("a[href='#prix-fix']").on('click', function () {
$('#menus').removeClass().addClass('animated fadeOutLeft');
$('#menus').one('animationend webkitAnimationEnd', function () {
$("#menus").hide();
$('#prix-fix-menu').show().removeClass().addClass('animated fadeInRight');
});
});
$("a:not(a[href='#prix-fix'])").on('click', function () {
$('#prix-fix-menu').removeClass().addClass('animated fadeOutRight');
$('#prix-fix-menu').one('animationend webkitAnimationEnd', function () {
$("#prix-fix-menu").hide();
$('#menus').show().removeClass().addClass('animated fadeInLeft');
});
});
I also have a smooth scroll script (positioned after the previous script in at the bottom of the tag) working with the anchor links as well. Putting this here just in-case this is whats causing the problem even though I dont think so:
$('a[href^="#"]').on('click',function (e) {
e.preventDefault();
var target = this.hash;
var $target = $(target);
$('html, body').stop().animate({
'scrollTop': $target.offset().top
}, 900, 'swing', function () {
window.location.hash = target;
});
});
If more information like CSS or HTML are needed then let me know and Ill added but there's quite a lot of markup for the menu because of all the items.

Thanks in advance!
Following this CODE1
CODE1
$('#prix-fix-menu, #catering-menu').hide();
$("a[href='#prix-fix']").on('click', function () {
//add this line
$('#prix-fix-menu').unbind('animationend webkitAnimationEnd');
$('#menus').removeClass().addClass('animated fadeOutLeft');
$('#menus').one('animationend webkitAnimationEnd', function () {
$("#menus").hide();
$('#prix-fix-menu').show().removeClass().addClass('animated fadeInRight');
});
});
$("a:not(a[href='#prix-fix'])").on('click', function () {
//add this line
$('#menus').unbind('animationend webkitAnimationEnd');
$('#prix-fix-menu').removeClass().addClass('animated fadeOutRight');
$('#prix-fix-menu').one('animationend webkitAnimationEnd', function () {
$("#prix-fix-menu").hide();
$('#menus').show().removeClass().addClass('animated fadeInLeft');
});
});
your code may be caused multiple binding animationend webkitAnimationEnd, so animationend webkitAnimationEnd unbind before start animation.
WHY
Problem is animationend webkitAnimationEnd. animationend and webkitAnimationEnd is different event.
In your case, you tried to add two event at the same time. so another event leaves after trigger animation end. You can easily understand about this situation. Try following CODE2.
CODE2
$('#prix-fix-menu, #catering-menu').hide();
$("a[href='#prix-fix']").on('click', function () {
$('#menus').removeClass().addClass('animated fadeOutLeft');
$('#menus').one('webkitAnimationEnd', function () {
$("#menus").hide();
$('#prix-fix-menu').show().removeClass().addClass('animated fadeInRight');
});
});
$("a:not(a[href='#prix-fix'])").on('click', function () {
$('#prix-fix-menu').removeClass().addClass('animated fadeOutRight');
$('#prix-fix-menu').one('webkitAnimationEnd', function () {
$("#prix-fix-menu").hide();
$('#menus').show().removeClass().addClass('animated fadeInLeft');
});
});
In CODE2, remove only animationend event. It seems to work fine. But it has still problem when you click repeatedly same button. To work CODE2, you have to filter for user to click repeatedly same button using if-statement.

Javascript listener not firing if before end of jquery .slideDown() animation

simple one i hope!
The problem im having is that i have an ('itemID').mouseover, which fires a jquery slide-down animation for a menu box.
The problem is that if the mouse leaves the original item (in this case a text link) before the end of the slideDown() amination, the .mouseleave function is not called.
It works fine otherwise!!
This is what im using: (menu14 is the text link, FunctionsMenu3 is the hidden div containing the menu items)
$('#menu14').mouseover(function() {
$('#FunctionsMenu3').slideDown('fast', function() {
// Animation complete.
});
});
$('#FunctionsMenu3').mouseleave(function() {
$('#FunctionsMenu3').slideUp('fast', function() {
// Animation complete.
});
});
It seem to me that the JS CANT be fired, because its busy doing the slide...
site can be seen at http://www.impero-classroom-management.com
thanks in advance!!
On mouseleave, try .stop() to cancel the current animation.
$('#menu14').hover(
function() {
$('#FunctionsMenu3').slideDown('fast');
},
function() {
$('#FunctionsMenu3').stop().slideUp('fast');
}
);
Well i got around it in the end by not animating the drop down, only the slide up.
not a fix, but it was all i could really do!!
$('#FunctionsMenu5').mouseleave(function() {
$('#FunctionsMenu5').slideUp('fast', function() {
// Animation complete.
});
});
$('#menu15').mouseover(function() {
$('#FunctionsMenu5').show();
});

Fade in/out buttons on mouseover of an image with jQuery. A few bugs to work out

So, I essentially have what I want already, very simple, but there are some bugs. I just want so when you hover over an image, two left/right buttons appear on the image that allow you to click through other images. Then when you leave the image area (excluding the left/right buttons), the buttons fade out again. Here's what I've got:
$(document).ready(function() {
$('#image-slider').mouseenter(function(){
$('.next').fadeIn('50');
$('.prev').fadeIn('50');
}).mouseout(function(){
$('.next').fadeOut('50');
$('.prev').fadeOut('50');
});
});
Bug #1: However, when you mouseover the image the buttons appear, and if you mouse over the buttons, they disappear. Naturally, of course they do, this is because I told them to fade away when I left the image area. First of all, I need them to stay visible even when you hover over them. So I need to somehow include the buttons as part of my image area in my javascript. That's the first problem/
Bug #2: This is a common problem I see in javascript. When you hover over the image, the buttons fade in, hover off, they fade out. Of course, there's a duration to this, and if you keep hovering in/out/in/out/in/out before the duration can finish, then when you let it fly, it will go on and off and on and off. How can I prevent this? So that is you hover out of the image area while the buttons are fading in, it just stops the animation sequence in its tracks so you don't get that continuous fading in/out.
Thanks in advance!

ETA: the fix
I got it solved! A combination of your fix and #Pumou's.
I made another div just to wrap the two items and expanded it to cover the image, then I set the mouseover to be that div. Problem #1 solved.
I used puormo's .fadeTo() trick to solve problem #2.
Then, I used tweaks from everyone to shorten up the code so it was neat and tidy. Thanks to all!
I've decided on #jfriend00's solution. It's the shortest, great work!
Here's my final javascript:
$(document).ready(function() {
var b = $('.ps_next, .ps_prev');
$('#slider-wrapper').bind('mouseenter mouseleave', function(e) {
var check = ( e.type === 'mouseenter' ) ?
( b.stop(0,1).fadeIn(100) ) :
( b.stop(0,1).fadeOut(100) ) ;
});
});
Problem #2 can be fixed with .stop() which forces any previous animations to just to their conclusion before starting the next one.
$(document).ready(function() {
$('#imageContainer').hover(function() {
$('.ps_next').stop(true, true).fadeIn(400);
$('.ps_prev').stop(true, true).fadeIn(400);
}, function () {
$('.ps_next').stop(true, true).fadeOut(400);
$('.ps_prev').stop(true, true).fadeOut(400);
});
});
It may be better to use the .hover() jQuery function which handles both enter and leave rather than mouseenter() and mouseout().
You can see both an example of .stop() and .hover() on this jQuery doc page doing almost the exact same thing you are.
For problem #1, I think we'd need to see the structure of your HTML to know how best to advise on that as their are several choices depending upon how things are structured. You could also do the fadeOut on a delay that was cancelled if they hovered over the button so there was time to get the mouse to the buttons before they disappeared. Or, you could use .hover() on a container that contained both image and buttons.
You can see it working here: http://jsfiddle.net/jfriend00/Zk6rY/.
Shortened the code (as seen in the above jsFiddle) even more to this:
$(document).ready(function() {
$('#imageContainer').hover(function() {
$('.ps_button').stop(true, true).fadeIn(400);
}, function () {
$('.ps_button').stop(true, true).fadeOut(400);
});
});
$(document).ready(function() {
var $buttons = $('.next, .prev')
$('#image-slider').mouseenter(function(){
$buttons.stop().fadeTo('50','1');
$buttons.mouseenter(function() { $buttons.show(); });
}).mouseout(function(){
$buttons.stop().fadeTo('50','0');
});
});
I have also used stop();. I've also shortened it to use one selector to select both buttons (in this case, it was set to the variable $buttons).
I noticed that if your mouse entered the image div, and then left, and then entered again, the buttons were fading in to 50% opacity because of the stop();. I fixed this by using the fadeTo(); feature: the first one is the duration, which was set to 50 like yours, and the second one is the opacity to fade to (a number between 0 and 1).
I also solved the problem of keeping the buttons there when you hover over them. See this line:
$buttons.mouseenter(function() { $buttons.show(); });
This just uses show();, which gives the element display:block; on mouseover.
Example here: http://jsfiddle.net/purmou/MM4ba/1/
More about stop(); here: http://api.jquery.com/stop
More about fadeTo(); here: http://api.jquery.com/fadeto
EDIT: Updated the code so that it now uses jQuery's hover(); function. Shorter code is always better.
$(document).ready(function() {
var $buttons = $('.next, .prev')
$('#image-slider').hover(function(){
$buttons.stop().fadeTo('50','1');
$buttons.mouseenter(function() { $buttons.show(); });
},
function(){
$buttons.stop().fadeTo('50','0');
});
});

DEMO FIDDLE
var b = $('.btn');
$('#image-slider').bind('mouseenter mouseleave', function(e) {
var check = ( e.type === 'mouseenter' ) ?
( b.stop(false, true).fadeIn(300) ) :
( b.stop(false, true).fadeOut(300) ) ;
});
(with your markup and the use of ternary-operators)
You all might be looking for this awsmness.....
$(document).ready(function () {
$('#content').hover(function () {
$('.a').stop(true).fadeTo(500, 0.7);
$('.i').stop(true).fadeTo(500, 0.9);
}, function () {
$('.a').stop(true).fadeOut(500);
$('.i').stop(true).fadeTo(500, 1);
});
$('.a').hover(function () {
$('.i').stop(true).fadeTo(500, 0.95);
}, function () {
$('.a').stop(true).fadeTo(500, 0.7);
$('.i').stop(true).fadeTo(500, 0.9);

jQuery continuously scales a div element using hover()

I recently tried to use jQuery's effect('scale') function with the hover() function in jQuery. The idea is to enlarge the div element on mouseenter, and shrink it back to normal on mouseleave. The code is as follows:
$('.boxgrid').hover(function(){
$(this).effect('scale', {percent:125}, 1000);
}, function() {
$(this).effect('scale', {percent:80}, 1000);
});
I tried testing this in a jsfiddle, but instead of upscaling and downscaling once when a mouse enters the element, it keeps enlarging it. You can see the jsfiddle here. My question is how do I fix it? My understanding was that the mouseenter event was fired only once, and reset when the mouseleaves event is fired, but this seems to say otherwise? Am I missing something? Any help is greatly appreciated.
It calls the hover function every time the animation finishes. I modified it as follows and it appears to work:
window.boxScaled = false;
$('.boxgrid').hover(function(){
if(!window.boxScaled) {
window.boxScaled = true;
$(this).effect('scale', {percent:125}, 1000);
}
}, function() {
if(window.boxScaled) {
window.boxScaled = false;
$(this).effect('scale', {percent:80}, 1000)
}
});
I think you need to force the animation to stop if you leave the box before it has finished scaling (or reenter the box before it has shrunk):
$('.boxgrid').hover(function(){
$(this).stop().effect('scale', {percent:125}, 1000);
}, function() {
$(this).stop().effect('scale', {percent:80}, 1000);
});

Your understanding of hover (mouseenter/mouseleave) is correct, they should only fire once upon entering/leaving.

jQuery mouse out and not hiding a particular element

Let's say I've got two elements: an anchor which causes an occurence of a particular div.
In that single case I'm not able to wrap these two into a parent container, thus the whole markup has to be as following:
click me
<div class="info">info displayed on trigger hover</a>
The very basic question is: when the mouse leaves the trigger I want to hide the info window but only if the cursor is not over it.
How can I do that?
Help appreciated,
regards
If you can't change the markup at all, you can give it a nice fade effect, and take advantage of the fact a fade isn't instant, something like this would handle every .trigger/.info pair:
$(".trigger, .info").hover(function() {
$(this).next().andSelf().filter(".info").stop().animate({opacity: 1 });
}, function() {
$(this).next().andSelf().filter(".info").stop().animate({opacity: 0 });
});​​​​​​
You can try a demo here, you could break this info one function for .trigger and one for .info, I was just keeping it a bit more terse. The two function version would look like this:
$(".trigger, .info").hover(function() {
$(this).next().stop().animate({opacity: 1 });
}, function() {
$(this).next().stop().animate({opacity: 0 });
});
$(".info").hover(function() {
$(this).stop().animate({opacity: 1 });
}, function() {
$(this).stop().animate({opacity: 0 });
});
What this does is on mouseenter it fades in, on mouseleave it fades out (via .animate())...but moving the mouse from one to the other will let the fade happen for 1 frame before putting a .stop() to the fade-out and fade it back in. To the user, they don't see that anything happened, when the mouse leaves both, the fade is allowed to continue.
$('.trigger').live('mouseout',function (event) {
if (!$(event.relatedTarget).is('.info'))
$(this).next().hide();
});
