JQuery onclick div hide/show/reset for the next time clicked

Simple question from a newbie:
How do I reset/restart a function after completing the time of (500
ms) in order to repeat the function each time I click on a specific
button?
FIRST PART OF THE CODE WORKS
my div is disappearing after 500ms fading out
$('.animate-this').click(function () {
$('p').show().delay(500).fadeOut();
});
SECOND PART IS MISSING
I would need to reset the fuction in order to repeated immediately...
I guess there is a very simple solution for that..

fadeOut accepts a callback function. You can use that
function animate() {
$('p').show().delay(500).fadeOut('slow', function() {
animate()
});
}

pause executing function on purpose

I have a simple .click() function with some functions in it:
$mario.on('click', this, function() {
var width_mario = $window.width()/2;
$contentw.animate({left: '100%', marginLeft: -width_mario, marginTop: 0}, 600);
$fixed.css({'background-color': '#510000', 'left': '25%'});
createMario();
trigger(); // fire trigger not until createMario() is finished with animation
});
inside the function of createMario() are loads of jQuery .animate()ions. What I intend to do is, to fire trigger not until the animations of createMario()are finished. Something like the return function you can do if an animation is finished BUT inside the click function.
Thanks
edit: and not with setTimeout() because the animations have a random speed.

You can't literally do that. What you need to do instead is pass a reference to the trigger function into createMario and have it call that function when the animations are finished. Assuming the animations are via jQuery, they have a callback they call when they're done.

pass it as a callback, something like this:
function createMario(calback_fn) {
...
animate({...}, {duration: 12345, complete: callback_fn});
...
}
Make sure you add it to the longest animate call.
Note that may need to slightly change the animate syntax, see http://api.jquery.com/animate/ for different argument options).
Then do:
...
$fixed.css({'background-color': ... as before... });
createMario(trigger);

You can also use element.promise.done(function() { trigger(); }); if you're animating 1 element in the createMario function, or you can attach it to the longest animated element also (the one that takes the longest to finish), and it will call the trigger() function after that element has finished animating.
Here's a jsFiddle I put together that exemplifies this: http://jsfiddle.net/WPHmY/2/

why setInterval() cycle goes faster every time?

I'm building a custom slider on Javascript , and I want that every time the user clicks on a div of the slider, the slider should stop for X seconds.
My code is:
$(document).ready(function () {
var ciclo;
var index_slide = 1;
function startSlidercicle() {
ciclo = setInterval( function() {
// Slider code goes here
}, 3000);
}
//Here I start the slider animation
startSlidercicle();
//When the user clicks on a div called 'slide', stop the cycle and start again the animation cycle
$('.slide').on('click', function() {
clearInterval(ciclo);
setTimeout(startSlidercicle(), 3000);
});
});
But the problem is that everytime I click and stop the slider, the cycle starts faster and faster. How can I fix it?

Instead of:
clearInterval(ciclo);
setTimeout(startSlidercicle(), 3000);
or:
clearInterval(ciclo);
setTimeout(startSlidercicle, 3000);
I changed the code to be:
clearInterval(ciclo);
startSlidercicle();
And now the slider just works fine. I think that, in the first two proposals, every time I click on the div, a new function is created, "overlapping" over the existing cycle and, thus, it looks like the slider speeds up, but its just one cycle starting over another.

You need to change this:
clearInterval(ciclo);
setTimeout(startSlidercicle(), 3000);
to this:
clearInterval(ciclo);
setTimeout(startSlidercicle, 3000);
In your existing code, you are calling startSlidercirle immediately and it is not waiting until the setTimeout() fires because you have the () after the function name. That means to execute it immediately and pass the result of executing that to setTimeout(). You want to just pass the function reference to setTimeout() which is done by just having the name of the function with no () after it. This is a common mistake.

jQuery Isotope queue shuffle/randomize animation

I would like to set the jQuery Isotope shuffle method to to perform an animated shuffle of the loaded DOM elements every 30 seconds that someone is on the page with the plugin loaded.
I have had success tying the animation to a .hover() event, but I cannot seem to get it to fire when I use setInterval() or .queue(). I want the animation to fire regardless of user interaction/input.
var iso_shuffle = function() {
$('#isotope').isotope('shuffle');
}
setInterval(iso_shuffle(), 2500);
Why does the previous code not trigger the randomization, yet this does:
$('#isotope').hover(function() {
iso_shuffle()
});
Cheers

iso_shuffle() calls the function immediately. The function returns nothing. So your setInterval is actually doing the equivalent of:
setInterval(undefined, 2500);
You want to use the function name as the callback for setInterval:
setInterval(iso_shuffle, 2500);

You need to pass the function itself, not its return value:
setInterval(iso_shuffle, 2500);

Is there anyway on onmouseover to fire after mouseovering after a few seconds?

I want to make sure the user wants to have something pop up by mouseing over a div. I don't want the user to accidentally trigger something to pop up without intent. setTimeout doesn't work because even if it's very brief, the pop up will still pop up, it's just delayed. What I want is the user to mouseover something for 1sec for a pop up to display.
**update:
When I do this:
<div onmouseover="myTimer=setTimeout('display(this)', 5000);">
the timer works and it is displayed after 5 seconds but this is not passed and I can't get the element via $(element).next(), etc.
When I do this:
<div onmouseover="myTimer=setTimeout(display(this), 5000);">
the timer doesn't work. What is wrong, how can I get the timer and the this to be passed?
Thanks!
**update2: the this problem from here states: "Code executed by setTimeout() is run in a separate execution context to the function from which it was called. As a consequence, the this keyword for the called function will be set to the window (or global) object, it will not be the same as the this value for the function that called setTimeout."
I found the answer to overcome this here where you have to "save a reference to the context where the setTimeout function call is made"

This should work for you:
<div id="example">Hover me</div>
<script type="text/javascript">
(function(){
var timer;
var el = document.getElementById('example');
el.onmouseover = function(){
timer = setTimeout(function(){
display(el);
// If display takes no arguments and uses the "this" keyword inside it
// Use display.call(el); instead
}, 1000);
}
el.onmouseout = function(){
clearTimeout(timer);
}
})();
</script>
Example on JSFiddle

I'm pretty sure that this should works:
onmouseover="myTimer=setTimeout(yourFunctionName, 1000);"
You have also to add:
onmouseout="clearTimeout(myTimer);"

On mouse over you can start a timer. On mouse out reset the timer to 0. If the timer reaches 1s, you can trigger your event and reset the timer to 0.

I also later came across something called the hoverIntent jQuery Plug-in, worth checking out.
