MooTools - Fx.Element

Fx.Element 允许您将 Fx 功能添加到单个页面上的多个 dom 元素。实际上Fx.Element是Fx.Morph插件的扩展。Fx.Element 和 Fx.Morph 之间的唯一区别是语法。在此语法中，start({})方法用于创建效果，.set({}) 方法用于设置一些样式。

看一下 Fx.Element 的以下语法。

句法

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');
   }
});

启动({}) 和设置({})

start 和 set 关键字结构用于启动和设置样式。但在此结构中，您通过索引引用元素 - 第一个元素是 0，第二个元素是 1，依此类推。看一下 Start 和 Set 结构的以下语法。

句法

//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'
   }
});

例子

让我们举一个例子来解释 Fx.Element。看看下面的代码。

<!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>
