I am trying to use animation using jquery. When i mouseover the element, it increases the height and when mouseout, returns to original height.
The Problem is when i mouseover from one element to another element, the previous element's animation is still performing. how to stop the animation of the previous element?
Fiddle code:
http://jsfiddle.net/EVZVQ/
Use .stop(): http://api.jquery.com/stop
$('.div_1').mouseover(function(){
$(this).stop().animate({'height':'200px'},2000);
}).mouseout(function(){
$(this).stop().animate({'height':'100px'},2000);
});
Notice you can chain the event binding functions instead of selecting .div_1 twice in a row.
Here is a demo: http://jsfiddle.net/EVZVQ/1/
When .stop() is called on an element, the currently-running animation
(if any) is immediately stopped. If, for instance, an element is being
hidden with .slideUp() when .stop() is called, the element will now
still be displayed, but will be a fraction of its previous height.
Callback functions are not called.
Source: http://api.jquery.com/stop
Update
You can stop all the divs at once like this (but I'm not sure this is the effect you're looking for):
var $divs = $('.div_1');
$divs.mouseover(function(){
$divs.stop().filter(this).animate({'height':'200px'},250);
}).mouseout(function(){
$divs.stop().filter(this).animate({'height':'100px'},250);
});
Here is a demo: http://jsfiddle.net/EVZVQ/2/
This works better.
$('.div_1').mouseover(function(){
$(this).stop(true).animate({'height':'200px'},200);
});
$('.div_1').mouseout(function(){
$(this).stop(true).animate({'height':'100px'},200);
});

I have a page that uses
$(id).show("highlight", {}, 2000);
to highlight an element when I start a ajax request, that might fail so that I want to use something like
$(id).show("highlight", {color: "#FF0000"}, 2000);
in the error handler. The problem is that if the first highlight haven't finished, the second is placed in a queue and wont run until the first is ready. Hence the question: Can I somehow stop the first effect?
I listed this as a comment for the accepted answer, but I thought it would be a good idea to post it as a standalone answer as it seems to be helping some people having problems with .stop()
FYI - I was looking for this answer as well (trying to stop a Pulsate Effect), but I did have a .stop() in my code.
After reviewing the docs, I needed .stop(true, true)
From the jQuery docs:

Stop the currently-running animation on the matched elements....
When .stop() is called on an element, the currently-running animation (if any) is immediately stopped. If, for instance, an element is being hidden with .slideUp() when .stop() is called, the element will now still be displayed, but will be a fraction of its previous height. Callback functions are not called.
If more than one animation method is called on the same element, the later animations are placed in the effects queue for the element. These animations will not begin until the first one completes. When .stop() is called, the next animation in the queue begins immediately. If the clearQueue parameter is provided with a value of true, then the rest of the animations in the queue are removed and never run.
If the jumpToEnd argument is provided with a value of true, the current animation stops, but the element is immediately given its target values for each CSS property. In our above .slideUp() example, the element would be immediately hidden. The callback function is then immediately called, if provided...
.stop(true,true) will freeze the effect so if it's invisible at the time then it remains invisible. This could be a problem if you are using the pulsate effect.
$('#identifier').effect("pulsate", {times:5}, 1000);
To get around this I added
$('#identifier').stop(true, true).effect("pulsate", { times: 1 }, 1);
In my case, using below code does not work and keep your opacity value remain:
$('#identifier').stop(true, true).effect("pulsate", { times: 1 }, 1);
For me just remove opacity are working:
$('#identifier').stop(true, true).css('opacity','');
Trying to get a simple fadeIn/fadeOut work the way I want, basically, my problem is that it won't overwrite, or stop the function, if I've hovered over another element that triggers the action, and it kind puts it in a queue, and will play all the animations, even after my mouse is not even near the elements. I would like it to not let the function trigger again, unless the fadeout has been finished.
$("p").hover(
function()
{
$(document.getElementById('Bottom_Menu')).fadeIn(200);
},
function()
{
$(document.getElementById('Bottom_Menu')).fadeOut(350);
});
To quickly answer your question, you can use stop().
$("#Bottom_Menu").stop().fadeTo(200, 1);
You don't have to use document.getElementById; instead, just use #id. For classes, use .class. It's all built in to jQuery. :)
UPDATE
I'm now using fadeTo instead of fadeIn, because fadeIn only works when display is none. So if we're canceling the previous animation with stop(), we need to use fadeTo, since the display may not be none. (When you use fadeOut, it fades out the element, and when complete, it sets the element's display to none, which hides the element.)
Notes:
The second property of fadeTo is opacity.
fadeTo, like fadeIn, still automatically changes the display property so the element is visible.
$("#Bottom_Menu").clearQueue();
clears all pending animations/operations to do on this element
I thought this would do it, but it only delays the animation.
$("#searchsubmit").hover(
function () { $("#quicksearchtip").delay(100).slideDown("slow"); },
function () { $("#quicksearchtip").delay(100).slideUp("slow"); });
I don't want the event to fire if the user happens to accidentally pass the cursor over the element for a few milliseconds.
I want it to only occur when they hover over the element. It's very annoying when the cursor touches the element even for a split second the animation fires even after the mouse has left the element.
You're looking for the hoverIntent plugin.
You may ad a .stop(true) before both of the .delay() to empty the animation queue, so on quick mouse out, the delayed action will be removed.
I'm using jQuery to toggle the visibility of a <div> using the jQuery toggle method. The toggle is fired on the mouseenter and mouseleave event, thus creating the effect of the div to fold out on mouseenter and fold in on mouseleave. Problem is, if the user drags the mouse over the <div> a few times and then leaves the <div>, the div will toggle in and out several times. This can happen if the user accidentally moves around the mouse pointer in the <div> are. Do anyone have any idea on how I can avoid this behavior?
Thanx!
Two things:
If you're going to use both mouseenter and mouseleave I'd suggest using the hover() function; and
When using triggered animations it's a good habit to get into to use the stop() method.
So:
$("div.someclass").hover(function() {
$("...").stop().fadeIn("slow");
}, function() {
$("...").stop().fadeOut("slow");
});
Note: replace "..." with the appropriate selector for what you're toggling and use the appropriate effect (I'm using fade here). Also, this in an event handler refers to the source of the event.
You can use the more common mouseover/mouseout events to get a hover event that doesn't fire on internal mouse movements.
But don't use toggle on a mouse event, it can easily go wrong if eg. the mouse is over the element at page load time, or the mouse leaves the browser (which can allow the mouse to leave the bounds of the element without firing a mouseout). Have separate function for over which shows the content, and out which hides it.
Better: just use the hover() method which is meant for exactly this purpose.
Aside from the correct answer by Cletus, i'd like to point out that using mouseenter and mouseleave events is not wrong. The trick only resides into the stop() method, in fact we could still do:
$("div.someclass").on("mouseenter", function() {
$("...").stop().fadeIn("slow");
});
$("div.someclass").on("mouseleave", function() {
$("...").stop().fadeOut("slow");
});
Here is a jsFiddle example :)
