I'm using mouseover effect on a table list to show content of lesson on hover.
However, as it's in table, it's "changing too fast", when going from one row to another, that is why I would like to put some delay on the mouseover effect.
My code currently looks like this :
onmouseover="show('id')" onmouseout="hide('id')">
How to make a small delay ?
A non jQuery solution, for reference:
<script>
var show=function(x)
{
setTimeout(
function()
{
do the stuff...
},
200
);
};
var hide=function(x)
{
setTimeout(
function()
{
do the other stuff...
},
200
);
};
</script>
<div onmouseover="show('id')" onmouseout="show('id')"></div>
Basically, I've defined show and hide as functions which create anonymous functions that do the actual showing and hiding and then run them after a 200ms delay using setTimeout.
An awesome plugin by brain if you use jquery to control your hover actions and timers.
http://cherne.net/brian/resources/jquery.hoverIntent.html
or you can just use vannilla javascript to set timers.
If you are working with jQuery's show and hide methods you can simply put the desired duration in ms between the brackets:
<div onmouseover="$('#id').show(600)" onmouseout="$('#id').hide(600)">
some content
</div>

I want to replay my jquery function ChangeStats() every 5 seconds, it's currently doing sod all.
function ChangeStats() {
$('body').find('.admin-stats-big-figures-hidden').fadeIn(500);
setTimeout(function() {
$('body').find('.admin-stats-big-figures').fadeOut(500);
}, 500);
}
$(document).ready(function(){
setInterval(ChangeStats, 5000);
})();
Yes I have got the right class names.
No I haven't used underscores in my HTML.
I think it's something to do with my use of "find()", once the DOM has loaded and the function is set is it meant to traverse up the DOM tree instead of down?
EDIT:
Updated code, still not working.
HTML:
<span class="admin-stats-big-figures">%productCount%</span>
<span class="admin-stats-big-figures-hidden">hey</span>
Ok, I am going to go out on a limb and make several assumptions here; one is that you wish to cycle between two elements repeatedly, another is that you are using $(this) in the context of the window rather than a containing element. If either of these are incorrect then the following solution may not be suitable. However, let's give this a shot, eh?
1) You need to use setInterval rather than setTimeout to create a repeating call. You can of course "chain" your timeouts (ie: call the succeeding timeout from the code of the current timeout). This has some benefits in certain situations, but for now let's just assume you will use intervals rather than timeouts.
2) You call the find() jQuery method every time, which is a little unnecessary, especially if you will be repeating the actions so one idea would be to cache the lookup. If you are going to do that a custom object would be more suitable than separate global variables.
3) Some flexibility in terms of starting and stopping the animation could be provided. If we use a custom object as mentioned in (2) then that can easily be added.
4) You are using fadeIn and fadeOut, however if you wish the items to cycle then fadeToggle may be your best solution as it will simply allow you to do exactly that, toggle, without needing to check the current opacity state of the element.
5) Finally in my example I have provided a little extra "padding HTML" in order for the example to look good when run. Fading in jQuery will actually set the faded item to a CSS display of "none" which results in the content "jumping about" in this demo, so I have used some div's and a couple of HTML entity spaces to keep the formatting.
Ok, after all that here is the code..
// your custom animation object
var myAnim = {
// these will be cached variables used in the animation
elements : null,
interval : null,
// default values for fading and anim delays are set to allow them to be optional
delay : { fade: 500, anim: 200 },
// call the init() function in order to set the variables and trigger the animation
init : function(classNameOne, classNameTwo, fadeDelay, animDelay) {
this.elements = [$("."+classNameOne),$("."+classNameTwo)];
// if no fade and animation delays are provided (or if they are 0) the default ones are used
if (animDelay) this.delay.anim = animDelay;
if (fadeDelay) this.delay.fade= fadeDelay;
this.elements[0].fadeOut(function(){myAnim.start()});
},
// this is where the actual toggling happens, it uses the fadeToggle callback function to fade in/out one element once the previous fade has completed
update : function() {
this.elements[0].fadeToggle(this.delay.anim,function(el,delay){el.fadeToggle(delay)}(this.elements[1],this.delay.anim));
},
// the start() method allows you to (re)start the animation
start : function() {
if (this.interval) return; // do nothing if the animation is currently running
this.interval = setInterval(function(){myAnim.update()},this.delay.fade);
},
// and as you would expect the stop() stops it.
stop : function () {
if (!this.interval) return; // do nothing if the animation had already stopped
clearInterval(this.interval);
this.interval = null;
}
}
// this is the jQuery hook in order to run the animation the moment the document is ready
$(document).ready(
function(){
// the first two parameters are the two classnames of the elements
// the last two parameters are the delay between the animation repeating and the time taken for each animation (fade) to happen. The first one should always be bigger
myAnim.init("admin-stats-big-figures","admin-stats-big-figures-hidden",500,200);
}
);
OK, so now we need the HTML to compliment this (as I say I have added a little formatting):
<div><span class="admin-stats-big-figures">One</span> </div>
<div><span class="admin-stats-big-figures-hidden">Two</span> </div>
<hr/>
<input type="button" value="Start" onclick="myAnim.start()"/> | <input type="button" value="Stop" onclick="myAnim.stop()"/>
I have also provided buttons to stop/start the animation. You can see a working example at this JSFiddle - although the stop/start buttons are not working (presumably something specific to JSFiddle) they do work when in context though.
Here im gonna just replace your $(this). and maybe it'll work then.. also using callback.
function ChangeStats() {
$('body').find('.admin-stats-big-figures-hidden').fadeIn(500, function() {
$('body').find('.admin-stats-big-figures').fadeOut(500);
});
}
$(document).ready(function(){
setTimeout('ChangeStats()', 5000);
});
hoping someone can help.
I'm a javascript novice. I have a list of names that, when hovered over, display a box with that person's contact information.
The problem I'm having is that the box displays too fast; causing boxes to fire off rapidly when mousing over multiple names.
Link: http://law.nd.edu/faculty/
Here's what I believe is the relevant code:
<script>
jQuery(".directory-list li").hover(
function() {
jQuery(this).find(".directory-info").fadeIn(200); ;
},
function() {
jQuery(this).find(".directory-info").fadeOut(50);;
}
);
</script>
Thanks for any help.
Use hoverIntent instead.
There is a nice little plugin for it, that is the easiest way to do it.
http://cherne.net/brian/resources/jquery.hoverIntent.html
It will keep your elements from rapid-firing.
The easiest way would be to add a delay before your fadeIn:
jQuery(this).find(".directory-info").delay(300).fadeIn(200);
You can introduce a delay by using setTimeout as follows:
var hoverTimer;
jQuery(".directory-list li").hover(function() {
var elem = jQuery(this).find(".directory-info");
hoverTimer = setTimeout(function() {
elem.fadeIn(200);
}, 1000); // wait for one second and then fadeIn
},
function() {
clearTimeout(hoverTimer);
jQuery(this).find(".directory-info").fadeOut(50);
});
Check out this fiddle, think this is what you want. The other answer that uses timeoutes will loose the context of this inside the setTimeout() function and will not work.

I'm trying to do a simple slide out effect, then add a class with display:none;
But for some reason, the jQuery animation is completing instantly, instead of using the duration as the docs say. I tried using different values, and 'slow' / 'fast'.
Looking at the source in Chrome's developer tools, the DOM is updated instantly. Removing the callback doesn't make the animation work either, it just does nothing in that case.
$('.type-panel').slideDown(500, function () {
$(this).addClass('panel-hidden')
});
<div class="ed-panel type-panel">
//bunch of stuff
</div>
What am I missing?
(I have jQuery and jQueryUI referenced)
I think you meant to use .slideUp() to hide it.
$('.type-panel').slideUp(500, function() {
$(this).addClass('panel-hidden');
});
Notice, .slideUp() will add automatically set the display to none.
I have an animation using Animate.CSS that I would like to have replay if the user would like but what I have attempted does not work. Here is the code:
HTML:
<div class="img-center">
<img src="path.jpg" class="feature-image animated rotateInDownRight" />
</div>
<p class="textcenter"> </p>
<div class="img-center">
Replay
</div>
JS:
var $j = jQuery.noConflict();
$j("#replay").click(function() {
$j('.feature-image').removeClass('animated rotateInDownRight').addClass('animated rotateInDownRight');
});
I do know the script itself works as I can see it happen in Firebug however that animation doesn't animate again. How do I achieve this with Animate.CSS?
This is just a guess but it appears that jQuery isn't "finished" removing the class before it adds it back in. I know this makes NO sense, but it's how JavaScript works. It can call the next function in the chain before all the stuff from the first one is finished. I poked around the code on Animate.CSS's site and saw that they use a timeout in their animation function. You might try the same. Here's their code:
function testAnim(x) {
$('#animateTest').removeClass().addClass(x);
var wait = window.setTimeout( function(){
$('#animateTest').removeClass()},
1300
);
}
What this is doing is exactly like what you are doing except that it waits for the animation to finish, then removes the classes. That way when the other class is added back in, it is truely "new" to the tag. Here is a slightly modified function:
function testAnim(elementId, animClasses) {
$(elementId).addClass(animClasses);
var wait = window.setTimeout( function(){
$(elementId).removeClass(animClasses)},
1300
);
}
Notice two things: First this code would allow you to change what element gets the animation. Second, you remove the classes you added after 1300 milliseconds. Still not 100% there, but it might get you further down the road.
It should be noted that if there is already some animation classes on the object it might break this JS.
found the right answer at animate.css issue#3
var $at = $('#animateTest').removeClass();
//timeout is important !!
setTimeout(function(){
$at.addClass('flash')
}, 10);
Actually a simpler version can avoid using JQuery too.
el.classList.remove('animated','flash');
//timeout is important !!
setTimeout(function(){
el.classList.add('animated','flash');
}, 10);
I believe the issue here is that when I remove the class it was adding the class to quickly. Here is how I solved this issue:
(HTML is same as above question).
JS:
var $j = jQuery.noConflict();
window.setTimeout( function(){
$j('.feature-image').removeClass('animated rotateInDownRight')},
1300);
$j("#replay").click(function() {
$j('.feature-image').addClass('animated rotateInDownRight');
});
What I believe is happening is the jQuery code is removing and adding the class to quickly. Regardless of the reason this code works.
If you wish you can also give a try to this javaScript side development that support animate.css animations. Here is an example of usage.
//Select the elements to animate and enjoy!
var elt = document.querySelector("#notification") ;
iJS.animate(elt, "shake") ;
//it return an AnimationPlayer object
//animation iteration and duration can also be indicated.
var vivifyElt = iJS.animate(elt, "bounce", 3, 500) ;
vivifyElt.onfinish = function(e) {
//doSomething ...;
}
// less than 1500ms later...changed mind!
vivifyElt.cancel();
Take a look here
My answer is a trick to add/remove the css class with a tint delay:
$('#Box').removeClass('animated').hide().delay(1).queue(function() {
$(this).addClass('animated').show().dequeue();
});
Also you can test it without hide/show methods:
$('#Box').removeClass('animated').delay(1).queue(function() {
$(this).addClass('animated').dequeue();
});
I fill it works smooth in chrome but it works with more unexpected delay in FF, so you can test this js timeout:
$('#Box').removeClass('animated');
setTimeout(function(){
$('#Box').addClass('animated');
}, 1);
This solution relies on React useEffect, and it's rather clean, as it avoids manipulating the class names directly.
It doesn't really answers the OP question (which seems to be using jQuery), but it might still be useful to many people using React and Animate CSS library.
const [repeatAnimation, setRepeatAnimation] = useState<boolean>(true);
/**
* When the displayedFrom changes, replay the animations of the component.
* It toggles the CSS classes injected in the component to force replaying the animations.
* Uses a short timeout that isn't noticeable to the human eye, but is necessary for the toggle to work properly.
*/
useEffect(() => {
setRepeatAnimation(false);
setTimeout(() => setRepeatAnimation(true), 100);
}, [displayedFrom]);
return (
<div
className={classnames('block-picker-menu', {
'animate__animated': repeatAnimation,
'animate__pulse': repeatAnimation,
})}
...
)
I'm required to develop a slideshow (not an existing one) with jQuery. I was able to change picture with a function that I created named changePic (takes an image link). It incorporates the fading animation from the jQuery library.
For the slideshow I'm trying to use a while loop. It kind of works, except that it doesn't wait for the animation to finish.
How do I, a) wait for the animation to finish, b) delay the changing picture so it display the picture for a couple of seconds?
Also tried Settimeout, and it doesn't work.
Edit:
Basically changing image is like this:
function changePic(imglink){
var imgnode = document.getElementById("galleryimg");
$(imgnode).fadeTo(500, 0, function(){
$(imgnode).attr("src", imglink);
$(imgnode).fadeTo(1000, 1);
})
}
and the slideshow code is like this, but obviously it shouldn't.
function slideshow(gallerylinks){
var i=0;
while (i<gallerylinks.length){
changePic(gallerylinks[i]);
i++;
}
}
You could always try ditching the while loop, and going with a perpetually recursive function...
on the .animate, you could add a timeout function (at whatever interval) that calls the changePic function. As I have no idea what your code looks like, I will provide a fantastically generic outline.
/* array of imgUrls */
var imgUrls = new Array(); //populate it however
changePic(slideToShowIndex, fadeOutSpeed, fadeInSpeed, slideDelay)
{
$('#slideHolder').animate({ opacity: 0}, fadeOutSpeed , function(){
$('#slideHolder').attr('src', imgUrls[slideToShowIndex]);
$('#slideHolder').animate({ opacity: 1 }, fadeInSpeed, function() {
setTimeout(function() { changePic(slideToShowIndex+1, fadeOutSpeed, fadeInSpeed, slideDelay);}, slideDelay});
});
}});
}
$(document).ready(function() {
changePic(0, 5000, 5000, 10000);
});
This should (in theory) fade the image out, swap it with the new one, and fade it in (both taking 5 seconds) and then adding a delay to call itself with the next slide index in 10 seconds.
This is in no way perfect, but does outline the general idea. Since we have no idea what your code looks like, I can only assume your setTimeout was in the wrong spot. Doing it like this will make sure that the animation has finished before the timeout is set. This guarantees that the slide wont change until after the animation has changed.
of course you could always use a combination of the ':not(:animated)' selector and a setInterval to achieve much the same effect.
EDIT: made a slight change to stack the animations properly. The thoery behind this still works even with the OPs addition of code.
You could have provided more details or example code but have a look at stop() and delay() functions.
