原标题:Copying or cloning an HTML element in Prototype

我有两箱,把物品从左边移到右边,现在我想改变行为,把分子从右边 co到左边。 我尝试使用原型图书馆的<代码>Oject.clone(o)和。 造成我的 b死,

目前,将要素从左边移到右边的法典如下:

$( left ).appendChild($( right ).options.item($( right ).selectedIndex));

我如何改变这种说法,即有一份内容的复印件,从左边到右边,而不是实际移动。

最佳回答

而不是Object.clone() use Element.clone()

var selected = $( right ).options.item($( right ).selectedIndex);
var copy = Element.clone(selected, true);
$( left ).appendChild(copy);
