On first click animation works good, on second it skips some steps

For this animation I use velocity.js and here is the code
$(document).ready(function() {
$('.shrink').on('click', function() {
$(".spread").removeClass("spread").addClass("shrink");
$(this).removeClass("shrink").addClass("spread");
$(".spread").velocity({
width: "80%"
}, 300);
$(".shrink").velocity({
width: "5%"
}, 300);
$('.spread').on('click', function() {
$(this).removeClass("spread").addClass("shrink");
$(".shrink").velocity({
width: "20%"
}, 300);
});
});
});
and the jsfiddle with full animation preview.
So, when you click on some column it opens and click again it closes. That is how it is supposed to work. But, the problem is if you now click again on the same column, it will open and close immediately, which is not the effect I want.
How can I fix this?
Btw, not sure why, but currently is not working in chrome, but it works in ff.

Learn about event delegation
simple rewrite of your code becomes
$(document).ready(function () {
$('body').on('click', '.spread', function () {
$(this).removeClass("spread").addClass("shrink");
$(".shrink").velocity({
width: "20%"
}, 300);
});
$('body').on('click', '.shrink', function () {
$(".spread").removeClass("spread").addClass("shrink");
$(this).removeClass("shrink").addClass("spread");
$(".spread").velocity({
width: "80%"
}, 300);
$(".shrink").velocity({
width: "5%"
}, 300);
});
});

How to add multiple event (mouseover/mouseout) into one selector

If I mouseover/mouseout very fast more than one time during animation times (here 900). Button is animating more than one time; even when I stopped mouse activity.
I want that it will take only one event for animation during animation times; even when multiple event triggered.
Other way I want to say if I triggered multiple mouseover event during 900 it will terminate immediately when I triggered mouseout and vice-versa.
$(document).ready(function () {
$("button").mouseover(function () {
$(this).css({
background: 'transparent',
color: '#09F'
});
$("button").animate({
width: "110%",
}, 900);
$(this).text("Show More >");
});
$("button").mouseout(function () {
$(this).css({
background: '#09F',
color: '#FFF'
});
$("button").animate({
width: "100%",
}, 900);
$(this).text("Show More");
});
});
Here's an JSFiddle to show you the behaviour

You need to use .stop()
Stop the currently-running animation on the matched elements.
Use
$(document).ready(function () {
$("button").mouseover(function () {
$(this).css({
background: 'transparent',
color: '#09F'
});
$("button").stop().animate({ //Here used stop
width: "110%",
}, 900);
$(this).text("Show More >");
});
$("button").mouseout(function () {
$(this).css({
background: '#09F',
color: '#FFF'
});
$("button").stop().animate({ //Here used stop
width: "100%",
}, 900);
$(this).text("Show More");
});
});
DEMO

Yes every time because you have some duration for example
$('somelemenent').animate({}, 400);
Your animation will stay in order if you hover element more quickly than your duration.
For this cases, you should set:
$('somelement').stop().animate(/* and your properties */);
Method .stop() stops all effects and orders which have connection with current element.

Use this : add another event after finishing previous one.
$(document).ready(function(){
$("button").mouseover(function() {
$( this ).css({background :'transparent',color : '#09F'});
$( "button").stop().animate({width: "110%",}, 900 );
$(this).text("Show More >");
}).mouseout(function() {
$( this ).css({background :'#09F',color : '#FFF'});
$( "button").stop().animate({width: "100%",}, 900 );
$(this).text("Show More");
});
});

jquery stop() doesn't work properly

I have some DIVs for products, and I have:
// mouseenter
$(document).on('mouseenter', '.productWrapper', function(){
$(this).stop(true,true);
$(this).find('.productWrapperContentVisible').animate({
height: '100px',
opacity: '1',
}, function(){
$(this).find('.productWrapperPrice').fadeIn();
$(this).find('.productWrapperByCompany').fadeIn();
});
});
// mouseleave
$(document).on('mouseleave', '.productWrapper', function(){
$(this).stop(true,true);
$(this).find('.productWrapperPrice').fadeOut('fast');
$(this).find('.productWrapperByCompany').fadeOut('fast');
$(this).find('.productWrapperContentVisible').animate({
height: '40px',
opacity: '.8',
});
});
and there are about 20 of products in each page, while I'm using stop(true,true), after I move my mouse on many of them many times, this doesn't work right, they continue to change height, and sometimes productWrapperPrice is still there while I don't have my mouse over there, it should go hidden.. .
sample: http://jsfiddle.net/gwsPB/
What's wrong with my code?
Thanks

Try this:
// mouseenter
$(document).on('mouseenter', '.productWrapper', function () {
$(this).find('.productWrapperContentVisible').stop(true, false).animate({
height: '100px',
opacity: '1'
}, function () {
$(this).find('.productWrapperPrice, .productWrapperByCompany').stop(true, true).fadeIn();
});
}).on('mouseleave', '.productWrapper', function () {
var $this = $(this);
$this.find('.productWrapperPrice, .productWrapperByCompany').stop(true, true).fadeOut('fast');
$this.find('.productWrapperContentVisible').stop(true, false).animate({
height: '40px',
opacity: '.8'
});
});
DEMO
The problem is: when you mouseenter and mouseleave immediately fast enough, your animate function in the mouseenter event is not finished yet. When your call $this.find('.productWrapperContentVisible').stop(true, true), the animation is stopped but the callback function is called which display them again
function () {
$(this).find('.productWrapperPrice, .productWrapperByCompany')
.stop(true, true).fadeIn();
}
By using stop(true, false), the callbacks are not called.

You need to call stop() on elements where are being animated, calling it on an ancestor element has no effect.
// mouseenter
$(document).on('mouseenter', '.productWrapper', function () {
$(this).find('.productWrapperContentVisible').stop(true, true).animate({
height: '100px',
opacity: '1'
}, function () {
$(this).find('.productWrapperPrice, .productWrapperByCompany').stop(true, true).fadeIn();
});
}).on('mouseleave', '.productWrapper', function () {
var $this = $(this);
$this.find('.productWrapperPrice, .productWrapperByCompany').stop(true, true).fadeOut('fast');
$this.find('.productWrapperContentVisible').stop(true, true).animate({
height: '40px',
opacity: '.8'
});
});

How to make a hover listener optional

I've been having some difficulties, could someone point me in the right direction for this fiddle?
I need the div to animate on hover, but only when the .isDown class has been added to a different element by the click function.
Fiddle
$(".move").click( function(event){
event.preventDefault();
if ($(this).hasClass("isDown") ) {
$(this).stop().animate({opacity:"0.5"}, 270);
$(this).removeClass("isDown");
//can put hover in here????
} else {
$(this).stop().animate({opacity:"1"}, 300);
$(this).addClass("isDown");
}
return false;
});
if ($(".move").hasClass("isDown")){
$(".funnyMOVE").hover(
function() {
$(this).stop().animate({top:"10px"},215);
},
function() {
$(this).stop().animate({top:"0px"},230);
});
}

Use the same condition inside the hover function. You are only binding the event in DOM ready based on the condition. So the event is never bound as the condition is false to start with.
$(".fuckerMOVE").hover(
function () {
if ($(".move").hasClass("isDown")) {
$(this).stop().animate({
top: "10px"
}, 215);
}
},
function () {
if ($(".move").hasClass("isDown")) {
$(this).stop().animate({
top: "0px"
}, 230);
}
});
Check Fiddle

Here is working code:
I removed your code outside of the .move click and put this in it:
$(".fuckerMOVE").hover(function () {
$(this).stop().animate({
top: "10px"
}, 215);
},
function () {
$(this).stop().animate({
top: "0px"
}, 230);
});
Fiddle
The problem was that if ($(".move").hasClass("isDown")){ was reached on document load, where this would have been false. My solution was just to apply the hover bind on the element directly when you are wanting it to be bound.
I actually just realized it looks like you were wanting to remove the bind if the .move is clicked again. If this is the case, you can move your bind into your else block and then add this to the if block:
$(".fuckerMOVE").off("mouseenter mouseleave");
The reason for mouseenter and mouseleave is that behind the scenes hover() sets listeners for these events.
Fiddle

not sure if this is what you want.
http://jsfiddle.net/hvLA6/
$("#move").click( function(event){
event.preventDefault();
if ($(this).hasClass("isDown") ){
$(this).stop().animate({opacity:"0.5"}, 270);
$(this).removeClass("isDown");
} else {
$(this).stop().animate({opacity:"1"}, 300);
$(this).addClass("isDown");
}
if ($("#move").hasClass("isDown")){
$(".fuckerMOVE").hover(
function() {
$(this).stop().animate({top:"10px"},215);
},
function() {
$(this).stop().animate({top:"0px"},230);
});
}
return false;
});
CSS
div {
width:100%;
height:100px;
background:black;
position:relative;
}
#move {
font-size:20px;
background:pink;
}

How to get `morpha.start()` after 2sec `mouseenter`?

Mootools: How to get morpha.start() after 2sec mouseenter?
window.addEvent('domready',function() {
var morph = new Fx.Morph('resize',{duration:700,delay:400});
$$('#resize').addEvent('mouseenter',function(e){
e.stop();
morpha.start({
width: '200px',
height: '100px'
});
}//It does not work on adding ',2000' here
);
<div id="resize" class="resize">DIV will get bigger after 2sec on mouseenter</div>

use delay.
http://www.jsfiddle.net/dimitar/m6JKt/ example
document.id('resize').set("morph", {duration:700,delay:400}).addEvents({
mouseenter: function(){
this.store("timer", (function() {
this.morph({
width: '200px',
height: '100px'
});
}).delay(2000, this));
},
mouseleave: function() {
$clear(this.retrieve("timer"));
}
});
this has also been refactored to use element.morph which does the class instance for you - and it will cancel the transition if you mouseout within the 2 seconds starting period grace.
