In this article, we will demonstrate the effect of Fold by using a JavaScript library called script.aculo.us having a smooth scaling down first in the vertical direction and then horizontal toward the left to finally disappear. We can adjust the duration of the effect as well.
Syntax:
Effect.Fold('id_of_element');
// Or
Effect.Fold('id_of_element', { duration: dur });
Parameters:
- id_of_element: Element on which the effect to be applied.
- duration: Duration taken by this effect.
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 FoldEffect() method which uses Fold() method of this library.Â
- By clicking on Click here to see the Fold effect, 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 FoldEffect(element){             new Effect.Fold(element, {duration:4});         }     </script> </head>    <body>     <div id = "myimage" onclick = "FoldEffect(this);">           <img height=200px width=200px             src = "gfg.png" alt = "gfg logo" />                       <h2>Click here to see the Fold effect </h2>     </div>    </body>    </html> |
Output:
Example 2: In this example, we have changed the duration of the effect and also added a button to see the effect.
