On mouse over enable button after 3 seconds, on mouse off disable and stop count down

I have a button that does something irreversible and I'm trying to put a lockout on it unless the user hovers over it for 3 seconds. If they wait 3 seconds the button becomes enabled. As soon as they mouse off it disables again. If they also mouse off during the count down of 3 seconds it stops the count down.
$('#delete_btn').on('mouseover', function () {
setTimeout(function () {
$('#delete_btn').prop('disabled', false)
}, 3000)
})
$('#delete_btn').on('mouseout', function () {
$('#delete_btn').prop('disabled', true)
})
I'm not sure how to stop the count down if they mouse out early

You need to clear the timeout. So, it's ready to fire on the next call:
var timeout;
$('#delete_btn').on('mouseover', function() {
timeout = setTimeout(function() {
$('#delete_btn').prop('disabled', false);
}, 3000);
});
$('#delete_btn').on('mouseout', function() {
clearTimeout(timeout);
$('#delete_btn').prop('disabled', true);
});
See it in work at CodePen:
https://codepen.io/aminshahrokhi/pen/VNJBYZ

this a copy-paste from W3School, basiclly you have to 'save' the timeout into a var, an then, on hover, clear the time out:
var myVar;
function myFunction() {
myVar = setTimeout(function(){ alert("Hello"); }, 3000);
}
function myStopFunction() {
clearTimeout(myVar);
}
I hope this helps :)

clearInterval not working with jquery .hover

I have a flipping effect using timeouts and setInterval with the following code:
// Flip and unflip panels
function startFlip() {
$('div#front-page-mosaic .front-box.flip').find('div').stop().rotate3Di('flip', 500, {direction: 'clockwise', sideChange: mySideChange});
setTimeout( function() {
$('div#front-page-mosaic .front-box.flip').find('div').stop().rotate3Di('unflip', 500, {sideChange: mySideChange});
}, 8500);
}
// Global flipping effect hook
var flip_hook;
// Autostart flipping effect
setTimeout( function() {
startFlip();
flip_hook = setInterval(function(){ startFlip(); }, 17000);
}, 8000);
// Stop the flipping effect
function stopFlip() {
clearInterval(flip_hook);
}
// Stop fliping on mouse hover, restart on mouse leave
$('div#front-page-mosaic .front-box.flip').hover(
function () {
stopFlip();
},
function () {
setTimeout( function() {
startFlip();
flip_hook = setInterval(function(){ startFlip(); }, 17000);
}, 8000);
}
);
But it does not stop the effect on mouseover. Seems it is not catching the clearInterval(). Any idea why?

You are calling a setTimeout to fire 8 seconds after. So if the user enters before that last setTimeout fires than it will still run. You need to cancel that timer also.
var delay;
function stopFlip() {
clearInterval(flip_hook);
clearTimeout(delay);
}
// Stop fliping on mouse hover, restart on mouse leave
$('div#front-page-mosaic .front-box.flip').hover(
function () {
stopFlip();
},
function () {
delay = setTimeout( function() {
startFlip();
flip_hook = setInterval(function(){ startFlip(); }, 17000);
}, 8000);
}
);

prevent animation double click issue

Hi I have problem with my slider please visit this site and check http://paruyr.bl.ee/
after click on my arrows it becomes work in an asynchronous way, ones it changes very fast and then slow and it repeats.
I think it is from start slider and stop slider.
var sliderPrev = 0,
sliderNext = 1;
$("#slider > img").fadeIn(1000);
startSlider();
function startSlider(){
count = $("#slider > img").size();
loop = setInterval(function(){
if (sliderNext>(count-1)) {
sliderNext = 0;
sliderPrev = 0;
};
$("#slider").animate({left:+(-sliderNext)*100+'%'},900);
sliderPrev = sliderNext;
sliderNext=sliderNext+1;
},6000)
}
function prev () {
var newSlide=sliderPrev-1;
showSlide(newSlide);
}
function next () {
var newSlide=sliderPrev+1;
showSlide(sliderNext);
}
function stopLoop () {
window.clearInterval(loop);
}
function showSlide(id) {
stopLoop();
if (id>(count-1)) {
id = 0;
} else if(id<0){
id=count-1;
}
$("#slider").animate({left:+(-id)*100+'%'},900);
sliderPrev = id;
sliderNext=id+1;
startSlider();
};
$("#slider, .arrows").hover(function() {
stopLoop()
}, function() {
startSlider()
});
function onlyNext () {
var newSlide=sliderPrev+1;
onlyShowSlide(newSlide);
}
function onlyShowSlide(id) {
if (id>(count-1)) {
id = 0;
} else if(id<0){
id=count-1;
}
$("#slider").animate({left:+(-id)*100+'%'},900);
sliderPrev = id;
sliderNext=id+1;
};

I think the best option would be to check if the animation is in progress and prevent the action if it is, something like this:
function prev () {
if(!$('#slider').is(":animated"))
{
var newSlide=sliderPrev-1;
showSlide(newSlide);
}
}
function next () {
if(!$('#slider').is(":animated"))
{
var newSlide=sliderPrev+1;
showSlide(sliderNext);
}
}
To illustrate the difference between this and just sticking a stop() in, check this JSFiddle. You will notice some choppy movements if you click multiple times in the stop() version.

What I would do is add a class to your slider when the animation starts and remove the class when it finishes:
$("#slider").animate({left:+(-id)*100+'%'}, {
duration: 900,
start: function() {
$('#slider').addClass('blocked');
},
complete: function() {
$('#slider').removeClass('blocked');
}
});
Now check on each click event if the slider is blocked or not:
function next () {
if (!$('#slider').hasClass('blocked')) {
var newSlide=sliderPrev+1;
showSlide(sliderNext);
}
}
This is a very simple solution, I'm sure there is a better one.
EDIT: As marcjae pointed out, you could stop the animations from queuing. This means when you double click, the slideshow still will move 2 slides. With my approach the second click will be ignored completely.

You can use a variable flag to control if the animation is still being done, or simply use .stop() to avoid stacking the animation.
$("#pull").click(function(){
$("#togle-menu").stop().slideToggle("slow");
});

It is occurring because your animations are being queued.
Try adding:
.stop( true, true )
Before each of your animation methods. i.e.
$("#slider").stop( true, true ).animate({left:+(-id)*100+'%'},900);

The answers about stop are good, but you have a bigger issue that is causing the described behavior. The issue is here:
$("#slider, .arrows").hover(function() {
stopLoop()
}, function() {
startSlider()
});
You have bound this to the .arrows as well as the #slider and the arrows are contained within the slider. So, when you mouse out of an arrow and then out of the entire slider, you are calling start twice in a row without calling stop between. You can see this if you hover onto the arrow and then off of the slider multiple times in a row. The slides will change many times after 6 seconds.
Similarly, consider the case of a single click:
Enter the `#slider` [stopLoop]
Enter the `.arrows` [stopLoop]
Click the arrow [stopLoop]
[startSlider]
Leave the `.arrows` [startSlider]
Leave the `#slider` [startSlider]
As you can see from this sequence of events, startSlider is called 3 times in a row without calling stopLoop inbetween. The result is 3 intervals created, 2 of which will not be stopped the next time stopLoop is called.
You should just have this hover on the #slider and more importantly, add a call to stopLoop as the first step in startSlider. That will ensure that the interval is always cleared before creating a new one.
$("#slider").hover(function() {
stopLoop()
}, function() {
startSlider()
});
function startSlider(){
stopLoop();
/* start the slider */
}

Anonymous function in setTimeout not working

I'm trying to create a delay between two loops of the nivo-slider.
Without the setTimeout everything works just fine (but without delay). So the folloing example works:
$('#slider').nivoSlider({
lastSlide: function(){
$('#slider').data('nivo:vars').stop = true;
// setTimeout(function() {
$('#slider').data('nivo:vars').stop = false;
// }, 2000);
},
});
If I uncomment the setTimeout-lines the slider stops but does not start again? Any ideas why?
Update:
http://jsfiddle.net/kgYNX/
2nd update:
Tried it with a wrapping function, too. The function gets called but if I use setTimeout in the new function it stops working: http://jsfiddle.net/kgYNX/1/

Solved it slightly different:
beforeChange: function(){
$('#slider').data('nivo:vars').stop = true;
var delay = 0;
if ($('#slider').data('nivo:vars').currentSlide == $('#slider').data('nivo:vars').totalSlides - 2) {
delay = 2000;
}
setTimeout(function() {
$('#slider').data('nivo:vars').stop = false;
}, delay);
}
I don't know why "totalSlides - 2", but it works: http://jsfiddle.net/kgYNX/15/

As a variant, you may add custom option to slider vars collection to prevent stop execution on lastSlide handler when slider re-enabled by timeout:
lastSlide: function () {
var dontStop = $('#slider').data('nivo:vars').dontStopOnLast;
if (!dontStop) {
$('#slider').data("nivoslider").stop();
setTimeout(function () {
$('#slider').data("nivoslider").start();
}, 2000);
}
$('#slider').data('nivo:vars').dontStopOnLast = !dontStop;
}

does jQuery stop() work on custom functions?

There are three images that I have made a tooltip for each.
I wanted to show tooltips within timed intervals say for 2 seconds first tooltip shows and for the second interval the 2nd tooltips fades in and so on.
for example it can be done with this function
function cycle(id) {
var nextId = (id == "block1") ? "block2": "block1";
$("#" + id)
.delay(shortIntervalTime)
.fadeIn(500)
.delay(longIntervalTime)
.fadeOut(500, function() {cycle(nextId)});
}
now what i want is to stop the cycle function when moseover action occurs on each of the images and show the corresponding tooltip. And again when the mouse went away again the cycle function fires.

If I understand everthing correctly, than try this code. Tt stops the proccess if you hover the image and continues if you leave the image. The stop() function will work on custom functions if you implement them like the fadeOut(), slideIn(), ... functions of jquery.
$('#' + id)
.fadeIn(500, function () {
var img = $(this).find('img'),
self = $(this),
fadeOut = true;
img.hover(function () {
fadeOut = false;
},
function () {
window.setTimeout(function () {
self.fadeOut(500);
}, 2000);
}
);
window.setTimeout(function () {
if (fadeOut === false) {
return;
}
self.fadeOut(500);
}, 2000);
});​
