jQuery Animation Examples with Code
A simple jQuery animate example
In this post, I'm going to show you how easy it is to use jQuery to change a CSS property so you can add animation effects to your page.
For example, you can use jQuery animations to make something like this:
You'll learn about the options available for jQuery animation effects and how to animate multiple elements sequentially. You'll also learn how to animate backgroundColor and create a show/hide effect with jQuery. When you're finished with these examples, you'll know how to use jQuery to make great CSS animations.
Let's get started...
Quick Explanation
The animate() is a jQuery method that is used for changing CSS property of an Element with effects.
$(selector).animate( properties , duration, easing , complete)
An element/s that will have the animation effect
An object of CSS properties and values that the animation will move toward.
The time where the element will complete the animation.
Values: fast (200 ms), slow (600 ms) or any number in miliseconds.
Default: 400
The transition on how the animation will run.
Values:
swing or
linear Default:
swing
DIfference of
swing and
linear movement in graph
![]()
swing starts slowly and gradually increasing speed and slows down before it reaches the end of the duration
![]()
linear from start to end it moves with same speed
a function to execute after the animation is finished.
Default: fn(){}
Example Code
Here is an example where we animate an Element's width and sends a message when the animation is finished:
HTML <div id="changeMyWidth"></div> CSS #changeMyWidth{
background: #ff000066;
width: 100px;
height: 100px;
margin-bottom:15px;
} JS /*Changes Width on click*/
$('#btnAnimate').click(function(){
$('#changeMyWidth').animate(
{
width: '200px'
},
400,
"swing",
function(){
alert("Animation done!");
}
);
});
Tips
-
properties are not all css properties. Some properties must have a "Camel Case" style.
$('#elementId').animate({
background:'#fff'
},"slow");
The above code will not work
$('#elementId').animate({
backgroundColor:'#fff'
},"slow");
The above code will work. Which is equivalent to background-color:#fff in css.
The same will also be applied to other css properties like {marginTop:0px} , {borderColor:'#000'}
-
You can also chain animate() to execute another transition after the effect.
$('#changeMyWidth')
.animate(
{
width: '200px'
},
400,
"swing",
function(){
console.log("Width changed to 200px");
})
.animate(
{
width: '100px'
},
400,
"swing",
function(){
console.log("Width changed to 100px");
});
The above code will make #changeMyWidth's to 200px within 400ms and turns it back too 100px after it's done.
