How to define easing option in jquery animation? - javascript

I need to set easing 'easeInCubic' on an animation done using jQuery.
Here my code:
$('#content-scroll-inner:not(:animated)').animate({ 'top': moveOf}, this.animationSpeed, this.cbEndAnimation.bind(this));
Trying something like
$('#content-scroll-inner:not(:animated)').animate({ 'top': moveOf},'easeInCubic', this.animationSpeed, this.cbEndAnimation.bind(this));
What am I doing wrong and how to fix it?

Use easing option to set easing effect:
easing: 'easeInCubic'
This way:
$('#content-scroll-inner:not(:animated)').animate({ 'top': moveOf},easing:'easeInCubic', this.animationSpeed, this.cbEndAnimation.bind(this));

Use easing
Optional. Specifies the speed of the element in different points of
the animation. Default value is "swing". Possible values: "swing" -
moves slower at the beginning/end, but faster in the middle "linear" -
moves in a constant speed Tip: More easing functions are available in
external plugins.
With animate():
$('#content-scroll-inner:not(:animated)').animate({ 'top': moveOf},easing:'easeInCubic', this.animationSpeed, this.cbEndAnimation.bind(this));
With addClass()
$('.foot').addClass('slide-down', 1000, 'easeInCubic');

use easing: and make sure to add jquery.ui.js in your script tag. Please read this documentation

JQuery ScrollLeft with easing [duplicate]

This question already has answers here:
TypeError: p.easing[this.easing] is not a function
(12 answers)
Closed 8 years ago.
I am trying to scrollLeft with an easing applied.
It scrolls just fine if I took out the ease
$("#content").animate({
scrollLeft: '+=' + $(window).width()
}, "slow");
But when I try to add an easing to the animation
$("#content").animate({
scrollLeft: '+=' + $(window).width()
}, "slow", "easeInOutBounce");
I get an error that looks like:
TypeError: m.easing[this.easing] is not a function
Any help would be appreciated
easeInOutBounce is not part of the default set of jQuery easings. You’ll need to include jQuery UI’s easing library to have access to this. Either just include the whole of jQuery UI, or build yourself a custom version of the library containing just the easing components. Include this after including jQuery and before your code.
You have to add 'easeInOutBounce' to jquery easing array, otherwise you only can use 'linear' or 'swing'.
There are plugins to add easing curves to jquery, jquery-ui adds many of them including 'easeInOutBounce'
I think you need the JQuery UI to have access to this kind of easing.
Source (JQuery documentation):
Easing
The remaining parameter of .animate() is a string naming an easing function to use. An easing function specifies the speed at which the animation progresses at different points within the animation. The only easing implementations in the jQuery library are the default, called swing, and one that progresses at a constant pace, called linear. More easing functions are available with the use of plug-ins, most notably the jQuery UI suite.

Rapahel js : dynamic positioning and animations

I'm new to js and web dev in general, and i want to add animations to my website using raphael js.
Here is the code I use for a basic slide-in animation:
paper.text('1000','25%','this is a\ntest').animate({x: '50'}, 1000, 'linear');
(test it here)
It works fine when i put fixed values for the x parameter. However, when i use dynamic positioning, the animation doesn't occur, and the text waits for the duration of the animation before positioning itself. At least the final positioning is what i'm looking for:
paper.text('300%','25%','this is a\ntest').animate({x: '50%'}, 1000, 'linear');
Why isn't it working ?
Is there a way around ?
I'm not sure raph can work like that (animating to a percentage), I may be wrong though.
Is this the sort of thing you are after ?
paper.text( paper.width * 3,'25%','this is a\ntest').animate({x: paper.width / 2}, 1000, 'linear');

jQuery Cycle plugin: scroll slides horizontally at constant speed, without easing

I'm using jQuery Cycle plugin. When I use 'scrollHorz' as the value of fx property, slides move not at constant speed, but with easing (see demo).
How can I make the slides move at constant speed?
Just use
easing: "linear"
and you should be fine!
For example:
$('#s1').cycle({
fx: 'scrollHorz',
easing: 'linear',
prev: '#prev1',
next: '#next1',
timeout: 0
});

rewrite this code to flying with easing not fadein

How to rewrite this code, so it would fly in with easing not just fade in.
Code -
jQuery('#swiftslider-slide-'+newSlide).addClass('active').fadeIn('300');
Could you give me a full example? I understand I must use .animate() but if I do like this -
jQuery('#swiftslider-slide-'+newSlide).addClass('active').animate({opacity: "show"}, { duration: "slow", easing: "easein" });;
it doesn't work.
Hope you will be able to help me.
Thanks, Sparky672.
It's not working because, by default, there's no such thing as easein
in jQuery. Without using your own function or plugin, the only two
default jQuery animation easing options are swing and linear. See this
question to learn more about easing functions.

Easing on Fixed Position Jquery

Is there anyway to add a easing to a fixed element?, I've been looking around and I can't find an answer. I really don't know how it would be, maybe something like...
$(window).scroll(function() {
$("#form").animate({position:"fixed", easing: 'swing'});
});
Any help will be appreciated ^ ^ Thanks!
Edit:Pretty much what I'm looking for is when user scrolls, the fixed element obviously will follow the window position, but I want to add is a little delay in comparison to scroll action with an easing effect
You'd have to make that div absolute positioned, z-indexed and without parent, then move it on the scroll event. You can know the number of pixels scrolled with scrollTop(). Something like this:
$(window).scroll(function(){
var offset=100;
//stop is called so easing doesn't affect while it is still scrolling.
$("form").stop().animate({top:($(window).scrollTop()+offset)+"px"}, 300, 'swing');
});
Try this instead:
$("#form").animate({position:"fixed"}, 300, 'swing');
From the jQuery api ( http://api.jquery.com/animate/ ):
The only easing implementations in the jQuery library are the default,
called swing, and one that progresses at a constant pace, called
linear. More easing functions are available with the use of plug-ins,
most notably the jQuery UI suite.
$("form").animate({position:"fixed"}, 300, 'swing'); //swing being default
