拖放与 starteffect 选项
说明
此选项用于定义可拖动对象开始拖动时要使用的效果。
默认情况下,它会在 0.2 秒内将元素的不透明度改为 0.2。
语法
new Draggable('element', {starteffect: 'effectFunction'});
其中 effectFunction 是函数,用于定义要应用的效果。
示例
<html> <head> <title>Draggables Elements</title> <script type = "text/javascript" src = "/javascript/prototype.js"></script> <script type = "text/javascript" src = "/javascript/scriptaculous.js"></script> <script type = "text/javascript"> window.onload = function() { new Draggable('myimage', {starteffect: effectFunction('myimage')}); } function effectFunction(element) { new Effect.Opacity(element, {from:0, to:1.0, duration:10}); } </script> </head> <body> <p>This image will display very slow in the start.</p> <img id = "myimage" src = "/images/scriptaculous.gif"/> </body> </html>
这将产生以下结果 −
