I am doing a rather simple Tween animation using MooTools. The opening animation is perfectly smooth. But then I added the closing animation (opposite of the opening animation), but it seems to stutter/hiccup at the end almost every time.
I tried the following with no success:
Removed all HTML content from the expanding DIV
Passing the Bounce settings directly to the Set function instead of using the variable
Commented the #content animation to be sure there is only 1 animation running
Commented the addClass and removeClass actions
I can't figure out what's causing the problem. Maybe someone else can have a look…
I put the test-case online here: http://dev.dvrs.eu/mootools/
window.addEvent('domready', function() {
// Set initial Div heights
$('sideBar').setStyle('height', window.getSize().y);
$('sideMenu').setStyle('height', window.getSize().y);
// Set Div heights on Window resize
window.addEvent('resize', function() {
$('sideBar').setStyle('height', window.getSize().y);
$('sideMenu').setStyle('height', window.getSize().y);
});
var bounce = {
transition: Fx.Transitions.Back.easeOut,
duration: 500
};
$$('.button.closeMenu').addEvent('click', function(event) {
event.preventDefault();
$$('.button').removeClass('active');
this.addClass('active');
$('sideMenu').set('tween', bounce);
$('sideMenu').tween('width', 0);
$('content').set('tween', bounce);
$('content').tween('margin-left', 90);
});
$$('.button.menu').addEvent('click', function(event) {
event.preventDefault();
$$('.button').removeClass('active');
this.addClass('active');
$('sideMenu').set('tween', bounce);
$('sideMenu').tween('width', 300);
$('content').set('tween', bounce);
$('content').tween('margin-left', 390);
});
});
Fiddle with example here
The transition you are using goes over the values defined as final value in the .set(property, value);. So when opening the final width is 300px but the transition/effect goes over that and than soft back to the final value.
This works great when opening because width can be 310px or more and then return to 300px, but when with has a transition under the with 0px, it doesn't work so good. It actually works ok if the final width is 10px (check here), but that's not the effect you want.
So my suggestion is to fix it with CSS, or change the transition when closing the sidebar, or use another effect altogether.
Option 1: fiddle - same transition opening, no easeout closing
Option 2: fiddle - same effect as you have but played with CSS and hidded 10px of the sidemenu under the sidebar. (z-index:3; on #sideBar and left:80px;width: 10px; on #sideMenu. Also 10px as the final value for the tween.)
To check different transitions at Mootools demo's look here.

I have a notification that pops up during difference instances on my site, and I'd like that notification to follow the menu that animates when you scroll down.
The code I have is as follows:
<script type='text/javascript'>
var messageFollow = $('.woocommerce-info').offset().top;
$(window).on( 'scroll', function(){
if ($(window).scrollTop() >= messageFollow) {
$('.woocommerce-info').css({top: "150px"});
} else {
$('.woocommerce-info').css({top: "74px"});
}
});
</script>
The notification has a value right now of top: 150px which looks great when you're at the top of the screen but top: 74px looks great when scrolled down.
I also want it to animate, but I have no idea how to implement that as well.
A clip to demonstrate: https://www.dropbox.com/s/p6i95f5gkbyn4nm/MessageNotification.mov?dl=0
jQuery has a built-in animate function.
Just replace css with animate and make sure the value is integer.
You can also give a duration in milliseconds as a second parameter to animate function.
$('.woocommerce-info').animate({top: 150},500);
I'm using this jQuery custom content scroller and it causes the scrollable section to flicker.
On clicking another random button it continuously flickers
If I take no action, it flickers on every few seconds interval
The code used:
$('.custom-scrollbar').mCustomScrollbar({
scrollInertia: 0,
alwaysShowScrollbar: 1, // adding / removing this causes no difference
scrollbarPosition: 'outside'
});
Attached a gif to demonstrate the issue: http://gyazo.com/9ea9d558f2630c74a157c70a367d1868
If it helps anyone: As a fix, I just added a 1px padding for the container; no more flickering.
This custom scrollbar flicks when its container has padding. Remove any padding from this container in css. Fox ex.
.mCSB_container.mCS_no_scrollbar_y.mCS_y_hidden
{
padding: 0px;
}
I could not find a CSS solution that worked in my specific case but disabling the updateOnContentResize advanced setting did the trick (of course, at the price of disabling the corresponding feature):
$(".content").mCustomScrollbar({
advanced: {
updateOnContentResize: false
}
});
I've thrown together a cool little script that will make my search box appear using jQuery UI. However, there are links above the search box that must move up at the same speed as well. For this, the margin-top must be adjusted, but by toggling the margin-top, it seems it is disappearing.
Does anyone know how I can toggle the margin-top without making the links disappear AND keep the speed as close as possible to the other one?
$(document).ready(function() {
$('.pwcustomsearch').hide();
$("#pwcustomsearchlink").click(function () {
var effect = 'slide';
var options = { direction: 'down' };
var duration = 400;
$('.pwcustomsearch').toggle(effect, options, duration);
$('.social-media').toggle({"marginTop": "15px"});
})
});
Here is a fiddle:
http://jsfiddle.net/hcmLw/1030/
.toggle() is adding display:none as an inline style to your element, therefore it disappears.
Use .animate() instead to change the top margin.
See my updated fiddle here: http://jsfiddle.net/hcmLw/1032/
EDIT: Updated the fiddle again to make the toggling work properly.
I have a JS feature on the following site that is working just fine in Firefox but not in Safari: http://rossbolger.com/kids/light-stories/
The feature slides out a grid of thumbnails called #image-thumbs when the mouse hovers over the container called #hit-area. It works (at least in Firefox) by first changing #image_thumbs height from '48px' to 'auto', the height is then measured using jQuery's height(). This height is stored in a variable and then using jQuery's css() it is given back to the #image-thumbs when the mouse is over.
The code on the site looks a little something like this:
// Thumbnails Nav Reveal and Hide Scripts
var thumbs_height = 1,
thumbs = $('#image-thumbs'),
thumbs_original_height = thumbs.css('height');
// Slide Up Thumbs
(function revealThumbs() {
// On hover let the thumbs become their full height
$('#image-thumbs #hit-area').hover(function(){ // Mouse over
// Get the unrestricted height of the thumbs
thumbs.css('height', 'auto');
thumbs_height = thumbs.height();
// then put it back to what it was so we can animate it using CSS3 transition
thumbs.css('height', 'inherit');
// delay 0.1s before triggering the change in height (time for the calculations to complete)
setTimeout( function() { thumbs.css('height', thumbs_height ) }, 100 );
}, function(){ // Mouse out
hideThumbs();
});
})();
// Hide thumbs
function hideThumbs(){
thumbs.css('height', thumbs_original_height );
};
The reason for measuring the unrestricted height and passing it back as a pixel value, rather than simply setting the height to 'auto', is to create a sliding effect via CSS3 (i.e. transition: height 0.5s). The transition only takes place if the affected attribute goes from one numeric value to another.
Thanks for any help bug testing this. I haven't even looked at other browsers yet.
All the best,
Laurence
Okay, so I've worked it out...
In the javascript document (scripts.js on the site) there was a function higher up the page calling the hideThumbs() function. So it wasn't working because the variables in hideThumbs() hadn't been declared at that point. Funny that it should still work in Firefox and IE9!
I've moved all this code to a point before that other function and the problem is now resolved. So far I've only done this locally. I'll update the site in the link above later.
In a webapp I'm working on, I want to create some slider divs that will move up and down with mouseover & mouseout (respectively.) I currently have it implemented with JQuery's hover() function, by using animate() and reducing/increasing it's top css value as needed. This works fairly well, actually.
The problem is that it tends to get stuck. If you move the mouse over it (especially near the bottom), and quickly remove it, it will slide up & down continuously and won't stop until it's completed 3-5 cycles. To me, it seems that the issue might have to do with one animation starting before another is done (e.g. the two are trying to run, so they slide back and forth.)
Okay, now for the code. Here's the basic JQuery that I'm using:
$('.slider').hover(
/* mouseover */
function(){
$(this).animate({
top : '-=120'
}, 300);
},
/* mouseout*/
function(){
$(this).animate({
top : '+=120'
}, 300);
}
);
I've also recreated the behavior in a JSFiddle.
Any ideas on what's going on? :)
==EDIT== UPDATED JSFiddle
It isn't perfect, but adding .stop(true,true) will prevent most of what you are seeing.
http://jsfiddle.net/W5EsJ/18/
If you hover from bottom up quickly, it will still flicker because you are moving your mouse out of the div causing the mouseout event to fire, animating the div back down.
You can lessen the flicker by reducing the delay, however it will still be present until the delay is 0 (no animation)
Update
I thought about it and realized that there is an obvious solution to this. Hoverintent-like functionality!
http://jsfiddle.net/W5EsJ/20/
$(document).ready(function() {
var timer;
$('.slider').hover(
/* mouseover */
function(){
var self = this;
timer = setTimeout(function(){
$(self).stop(true,true).animate({
top : '-=120'
}, 300).addClass('visible');
},150)
},
/* mouseout*/
function(){
clearTimeout(timer);
$(this).filter(".visible").stop(true,true).animate({
top : '+=120'
}, 300).removeClass("visible");
}
);
});
You could use .stop() and also use the outer container position
$(document).ready(function() {
$('.slider').hover(
/* mouseover */
function(){
$(this).stop().animate({
top : $('.outer').position().top
}, 300);
},
/* mouseout*/
function(){
$(this).stop().animate({
top : $('.outer').position().top + 120
}, 300);
}
);
});
DEMO
Hope this helps
Couldn't reproduce your issue but I believe that hover is getting called multiple times. To work around this you can check if the div is already in animation. If yes, then don't run another animation again.
Add following piece of code to check if the div is already 'animating':
if ($(this).is(':animated')) {
return;
}
Code: http://jsfiddle.net/W5EsJ/2/
Reference:http://api.jquery.com/animated-selector/
I understand the problem and reproduced it, it happens when hovering from the bottom up. The hovering with the mouse is what's causing the problem since the animation function will be called when the mouse hovers over the image. You need to control what happens here by using mouse enter and mouse leave, check out a similar example: Jquery Animate on Hover
The reason it's like that is because the hover is getting queued up causing it to slide up and down multiple times. There's a plug-in called hoverIntent which fixes the issue. http://cherne.net/brian/resources/jquery.hoverIntent.html
If you do decide to use hoverIntent, the only thing you have to change in your code is .hover > .hoverIntent
