MooTools - Fx.Element

Quiz

Fx.Element allows you to add the Fx functionality to multiple dom elements on a single page. Actually Fx.Element is an extension of the Fx.Morph plugin. The only difference between Fx.Element and Fx.Morph is the syntax. In this syntax, the start({}) method is used to create an effect and the .set({}) method is used to set some styles.

Take a look at the following syntax for Fx.Element.

Syntax

var fxElementsArray = $$('.myElementClass');
var fxElementsObject = new Fx.Elements(fxElementsArray, {
   //Fx Options
   link: 'chain',
   duration: 1000,
   transition: 'sine:in:out',
   
   //Fx Events
   onStart: function(){
      startInd.highlight('#C3E608');
   }
});

start({}) and set({})

Start and set keyword structures are used to start and set styles. But in this structure, you refer to the element via the index the first element is 0, the second is 1, and so on. Take a look at the following syntax for the Start and Set structures.

Syntax

//you can set your styles with .set({...})
fxElementsObject .set({
   '0': {
      'height': 10,
      'width': 10,
      'background-color': '#333'
   },
   '1': {
      'width': 10,
      'border': '1px dashed #333'
   }
});

//or create a transition effect with .start({...})
fxElementsObject .start({
   '0': {
      'height': [50, 200],
      'width': 50,
      'background-color': '#87AEE1'
   },
   '1': {
      'width': [100, 200],
      'border': '5px dashed #333'
   }
});

Example

Let us take an example that explains the Fx.Element. Take a look at the following code.

<!DOCTYPE html>
<html>

   <head>
      <style>
         .ind {
            width: 200px;
            padding: 10px;
            background-color: #87AEE1;
            font-weight: bold;
            border-bottom: 1px solid white;
         }
         .myElementClass {
            height: 50px;
            width: 100px;
            background-color: #FFFFCC;
            border: 1px solid #FFFFCC;
            padding: 20px;
         }
         #buttons {
            margin: 20px 0;
            display: block;
         }
      </style>
