$(document).ready(function () {
$("footer").mouseenter(function () {
$("footer").animate({ bottom: '+=62px' }, 500);
});
$("footer").mouseleave(function () {
$("footer").animate({ bottom: '-=62px' }, 500);
});
});

Try adding stop() to your animate functions. It stops the currently-running animation on the selected element.
$("footer").mouseenter(function () {
$("footer").stop().animate({ bottom: '+=62px' }, 500);
});
$("footer").mouseleave(function () {
$("footer").stop().animate({ bottom: '-=62px' }, 500);
});

jQuery animate - finish animation unless it's fired again

I am making a game like freaking-math using Phonegap and javascript.
I need to create similar timebar at the top. I use jQuery animate to animate the bar ... it works with the first answer only well .. then the second answer it starts but not exactly when the button is fired ..
how can I make it start just when the button fired and end too when it's fired again and end also after 3000ms if no answer were choosen ! ?
(function timeBar() {
$('.answer').on('touchstart', function(){
$('.progress').animate({ width: '0%' }, 3000)
$('.progress').animate({ width: '100%' }, 0);
});
})();
I have tried :
(function timeBar() {
$('.answer').on('touchstart', function(){
$('.progress').animate({ width: '0%' }, 3000);
});
$('.answer').on('touchend', function(){
$('.progress').animate({ width: '100%' }, 0);
});
})();
But not working :( !!

Here's one solution, given that you reload the page for every new math-question:
http://jsfiddle.net/daxro/uLd49zmp/1/
$(document).ready(function() {
$("#bar").animate({
width: '0%'
}, 3000);
});
...and here's another solution which includes a button: http://jsfiddle.net/daxro/uLd49zmp/3/

Toggle animation on click of div?

please look at this fiddle http://jsfiddle.net/rabelais/4X63B/3/
In this fiddle when one hovers on the bars the animations start and stop. I want to know how to change this Jquery code so that the animation starts and stops on click instead? Also when one animation is started and the user clicks on the other bar it will pause to. At the end of each animation a refresh button is display to reset the animation.
$('#one').mouseenter(function(){
$('.alt0').animate({width: $(this).width()}, ($(this).width())/2*1000,"linear",function(){
$("#refresh-1").show();
})
});
$('#refresh-1').click(function(){
$('.alt0').width(0);
$(this).hide();
})
$('#one').mouseleave(function(){
$('.alt0').stop()
});

Try
$('#one').on('click', function () { //when first is clicked
$('.alt1').stop(); //stop second animation
$('#two').removeClass('active'); //remove seconds active class
if ($(this).hasClass('active')) { //check if clicked item has active class
$('.alt0').stop(); //stop animation
$(this).removeClass('active'); //remove active class
} else { //if not active or animating
$(this).addClass('active'); //add active class
$('.alt0').animate({ //start animation
width: $(this).width()
}, ($(this).width()) / 2 * 1000, "linear", function () {
$("#refresh-1").show();
});
}
});
$('#refresh-1').click(function () {
$('.alt0').width(0);
$(this).hide();
})
Similarly do the same for second bar. If you dont want another bar to stop animating on click of other bar
just remove the part from code
$('.alt1').stop(); //stop second animation
$('#two').removeClass('active');
$('.alt0').stop(); //stop firstanimation
$('#one').removeClass('active');
Full example http://jsbin.com/UseTIji/1/

First change mouseenter to mouse click
$('#one').mouseenter(function() → $('#one').click(function()
Enter some variable that will change on every click:
var oneIsPlayed = false
$('#one').click(function() {
oneIsPlayed = !oneIsPlayed;
if ( oneIsPlayed ) {
//code to stop
} else {
//code to start animation
}
})

Breaking down the code:
$('#one').mouseenter(function(){
$('.alt0').animate({width: $(this).width()},
($(this).width())/2*1000,"linear",function(){
$("#refresh-1").show();
})});
This is the part that starts the animation when the mouse enters the element. You can change it so the animation starts on a mouse click by changing it to click:
$('#one').click(function(){
$('.alt0').animate({width: $(this).width()},
($(this).width())/2*1000,"linear",function(){
$("#refresh-1").show();
})});
You can do the same with the stop animation component:
$('#one').click(function(){
$('.alt0').stop()
});
If you want to make a click on one bar stop the animation on the other, you can add a stop method call to the start animation call:
e.g.
$('#two').click(function(){
$('.alt1').animate({width: $(this).width()},
($(this).width())/2*1000,"linear",function(){
$("#refresh-2").show();
$('.alt0').stop();
})});
It seems that you jsfiddle isn't loading for me at the moment, so I can't test. But I hope that can get you in the right direction.

On click of that div, applying animation. Give some duration for that animation and when the duration get over you can get its callback so then remove that style.
$(document).ready(function () {
$('#service').click(function () {
$("#ServiceSublist").animate({opacity: 0.25,
left: "+=50",
height: "toggle"
}, 1000, function() {
alert("amination complete");
});
});
});

Show image after there is hover on a link for 1500ms

I want to show an image after there is hover on link for atleast 1500ms or there is a click. How can I implement this minimal period hover condition while showing up the image ?
The image should remain visible until there is hover on the link or on itself. & should disappear as the mouse moves out of both. How can I implement this ? Thanks in advance!

http://jsfiddle.net/sSBxv/
$('a').click(function() {
alert(1); // alert on click
})
.hover(function() { // when mouse is entering
var $this = $(this);
// set timeout, save timeout id on element to clear later
$this.data('timeout', setTimeout(function() {
$this.click(); // click after 1500ms
}, 1500));
}, function() { // when mouse is leaving
clearTimeout($(this).data('timeout')); // stop the timeout
});

Try this
var hoverTimer;
$("linkSelector").hover(function() {
hoverTimer = setTimeout(function() {
$("imgSelector").show();
}, 1500);
}, function(){
clearTimeout(hoverTimer);
}).click(function(){
clearTimeout(hoverTimer);
$("imgSelector").show();
});

Something to the effect of...
$("#MyLinkSelectorId").hover(function() {
//Do anything you need to do here when it is clicked/hovered
setTimeout(function() {
//Do all of the other things here
}, 1500);
});
Switch out hover with click or bind multiple events to take care of both event types. To hide the images, you can either use a selector on the images with the .hide() method or you can set the opacity if the browser supports it.

$("a.class").hover( function (){ //First parameter is onmouseenter, show the image
$("img").show();
}, function (){ //second is onmouseleave, set a timeout that will hide the image
setTimeout( function(){
$("img").hide();
}, 1500);
}).click( function() { //on click, hide the image right away.
$("img").hide();
});

Since it looks like you haven't already tried something I'll give you the simplest way using jQuery (please note I haven't tested this):
$("#idOfDiv").mouseover(function() {
setTimeout("alertMsg()",1500);
});
function alertMsg()
{
alert('Ive been entered for 1500ms')
}
Also if you're serious about software development you should've been able to come up with this yourself.

I'm using the jQuery .scroll() function, why can't I override its effects with another function?

I'm using the jQuery .scroll() function to make a certain element fade to 0.2 opacity. Since there is no native "scrollstop" indicator, I decided to make the element fade back to 1.0 opacity on hover. However, it doesn't work.
Here's my code:
$(document).ready(function() {
$(window).scroll(function() {
$("#navlist").animate({ opacity: 0.2 }, 2000);
});
$("#navlist").hover(
function() {
$(this).animate({ opacity: 1 }, 500);
}, function() {
$(this).animate({ opacity: 1 }, 500); // just to be safe?
}
);
});
When I scroll, the #navlist element fades, but when you hover over it nothing happens. But if you refresh the page when you're half way down, the element automatically fades as soon as you refresh, before I've scrolled, and if you try to hover to fade it back in, nothing happens.
Any thoughts?

try to stop animation first
$(document).ready(function() {
$(window).scroll(function() {
$("#navlist").stop().animate({ opacity: 0.2 }, 2000);
});
$("#navlist").hover(function() {
$("#navlist").stop().animate({ opacity: 1.0 }, 500);
},
function() {
$("#navlist").stop().animate({ opacity: 1.0 }, 500);
}
);

The problem is that the scroll event, gets called multiple times during a single scroll (10-20 per a single mouse wheel scroll), so #navlist gets a lot of animate events of 2 seconds.
I am not exactly sure what's going on with jQuery, but when you hover it, even though the opacity: 1 animations run, they end up running the queued #navlist animations.
I solved the problem using a sort of flag, I bet you can find something more efficient.
$(document).ready(function(){
var isAnimationBusy = false;
$(window).scroll(function(){
if(isAnimationBusy) return;
isAnimationBusy = true;
$("#navlist").animate(
{ opacity: 0.2 }, 2000,
function(){ isAnimationBusy = false; }
);
});
$("#navlist").hover(
function(){
isAnimationBusy = false;
$(this).stop().animate({ opacity: 1 }, 500);
},
function(){
isAnimationBusy = false;
$(this).stop().animate({ opacity: 1 }, 500);
}
);
});
Edit: The animation stop will solve the problem, I still believe you should control how many times you call the animate event. There could be a performance hit.
