jQuery Effect - Animation

jQuery Animation - animate() method

jQuery animate() method is used to create custom animations.

Syntax:

$(selector).animate({params},speed,callback);

Required params parameter definitions form the animation CSS properties.

The optional speed parameter specifies the duration of the effect. It can take the following values: "slow", "fast", or milliseconds.

The optional callback parameter is the name of the function to be executed after the animation is completed.

The following example demonstrates a simple application of the animate() method. It moves the <div> element 250 pixels to the right:

Example

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<script src="http://libs.baidu.com/jquery/1.10.2/jquery.min.js">
</script>
<script> 
$(document).ready(function(){
  $("button").click(function(){
    $("div").animate({left:'250px'});
  });
});
</script> 
</head>
 
<body>
<button>开始动画</button>
<p>默认情况下，所有的 HTML 元素有一个静态的位置，且是不可移动的。 
如果需要改变为，我们需要将元素的 position 属性设置为 relative, fixed, 或 absolute!</p>
<div style="background:#98bf21;height:100px;width:100px;position:absolute;">
</div>

</body>
</html>

Note: By default, all HTML elements have a static position and cannot be moved.
If you need to operate the position, remember to first set the CSS position property of the element to relative, fixed or absolute!

#jQuery animate() - Manipulating Multiple Properties

Please note that multiple attributes can be used at the same time during the animation generation process:

Instance

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<script src="http://libs.baidu.com/jquery/1.10.2/jquery.min.js">
</script>
<script> 
$(document).ready(function(){
  $("button").click(function(){
    $("div").animate({
      left:'250px',
      opacity:'0.5',
      height:'150px',
      width:'150px'
    });
  });
});
</script> 
</head>
 
<body>
<button>开始动画</button>
<p>默认情况下，所有的 HTML 元素有一个静态的位置，且是不可移动的。 
如果需要改变为，我们需要将元素的 position 属性设置为 relative, fixed, 或 absolute!</p>
<div style="background:#98bf21;height:100px;width:100px;position:absolute;">
</div>

</body>
</html>

Note:

Can the animate() method be used to operate all CSS properties?

Yes, almost! However, there is one important thing to remember: when using animate(), you must use Camel notation to write all property names, for example, you must use paddingLeft instead of padding-left, use marginRight instead of margin-right, etc. .

Also, color animation is not included in the core jQuery library.

If you need to generate color animation, you need to download the Color Animation plug-in from jquery.com.

##jQuery animate() - using relative values
It is also possible to define relative values ​​(the value is relative to the element's current value). You need to add += or -= in front of the value:

Instance

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<script src="http://libs.baidu.com/jquery/1.10.2/jquery.min.js">
</script>
<script> 
$(document).ready(function(){
  $("button").click(function(){
    $("div").animate({
      left:'250px',
      height:'+=150px',
      width:'+=150px'
    });
  });
});
</script> 
</head>
 
<body>
<button>开始动画</button>
<p>默认情况下，所有的 HTML 元素有一个静态的位置，且是不可移动的。 
如果需要改变为，我们需要将元素的 position 属性设置为 relative, fixed, 或 absolute!</p>
<div style="background:#98bf21;height:100px;width:100px;position:absolute;">
</div>

</body>
</html>

##jQuery animate() - Using the queue function

By default, jQuery provides queue functionality for animations.

This means that if you write multiple animate() calls after each other, jQuery will create an "internal" queue containing those method calls. Then run these animate calls one by one.

Instance

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<script src="http://libs.baidu.com/jquery/1.10.2/jquery.min.js">
</script>
<script> 
$(document).ready(function(){
  $("button").click(function(){
    var div=$("div");
    div.animate({height:'300px',opacity:'0.4'},"slow");
    div.animate({width:'300px',opacity:'0.8'},"slow");
    div.animate({height:'100px',opacity:'0.4'},"slow");
    div.animate({width:'100px',opacity:'0.8'},"slow");
  });
});
</script> 
</head>
 
<body>
<button>开始动画</button>
<p>默认情况下，所有的 HTML 元素有一个静态的位置，且是不可移动的。 
如果需要改变为，我们需要将元素的 position 属性设置为 relative, fixed, 或 absolute!</p>
<div style="background:#98bf21;height:100px;width:100px;position:absolute;">
</div>

</body>
</html>

<script> 
$(document).ready(function(){
  $("button").click(function(){
    var div=$("div");  
    div.animate({left:'100px'},"slow");
    div.animate({fontSize:'3em'},"slow");
  });
});
</script> 
</head>
 
<body>
<button>开始动画</button>
