使用 revert 选项进行拖放
说明
如果设置为 true，则元素在拖动结束时返回其原始位置。它还指定在拖动操作停止时是否调用 reverteffect 回调。默认为 false。
语法
以下是设置 revert 选项的简单语法。
new Draggable('element', {revert:true});
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', {revert:true} );
}
</script>
</head>
<body>
<p>Drag it and then leave it to see the result:</p>
<img id = "myimage" src = "/images/scriptaculous.gif"/>
</body>
</html>
这将产生以下结果 −
scriptaculous_drag_drop.html
