script.aculo.us Shrink Effect

Last Updated : 03 Dec, 2020

In this article, we will demonstrate the effect of Shrink by using a JavaScript library called script.aculo.us shrinking an element into a particular direction and hiding when the effect is complete. We can adjust the duration of the effect as well.

Syntax:

Effect.Shrink('id_of_element');

// or

Effect.Shrink('id_of_element', { duration: dur });

// or

Effect.Shrink('id_of_element', { direction:'direction' });

Parameters:

id_of_element: Element on which the effect to be applied.
duration: Duration taken by this effect.
direction: The direction to be shrunk, defaults to center.

Note: To use this library we are supposed to download or install the library and then use it in our programs. And to do so you can follow this link http://script.aculo.us/downloads.

Approach:

To demonstrate the use of this function, we have written a small piece of code. In which we have written a small JavaScript function named ShrinkEffect() method which uses Shrink() method of this library.
By clicking on Click Image to Shrink, you will see the effect clearly.

Example 1: To see the effect, first install the library and then open the following program in the local environment.

HTML

<!DOCTYPE html> 
<html> 
  
<head> 
    <script src="prototype.js"></script> 
    <script src= 
        "scriptaculous.js?load = effects"> 
    </script> 
  
    <script type="text/javascript"> 
        function ShrinkEffect(element) { 
            new Effect.Shrink(element, { duration: 4 }); 
        } 
    </script> 
</head> 
  
<body> 
    <div id="myimage" onclick="ShrinkEffect(this);"> 
        <img height=200px width=200px 
            src="gfg.png" alt="gfg logo" /> 
  
        <h2>Click here to see the Shrink effect</h2> 
    </div> 
</body> 
  
</html> 

Output:

Example 2: In this example, we have used the direction of the effect as ‘bottom-left’ and also added a button for the effect to appear.
