问题描述
这是我目前所拥有的:http://jsfiddle.net/beCVL/5/
这就是我试图覆盖默认 cloneNode 的方式:Object.defineProperty(Object.prototype, "cloneNode", {得到:cloneNode2,设置:cloneNode2});
This is how I'm trying to override the default cloneNode:Object.defineProperty(Object.prototype, "cloneNode", { get: cloneNode2, set: cloneNode2});
但它不起作用,所以,我认为 Object.prototype 没有 cloneNode,但 Element.prototype 也没有.
but it's not working, so, I think Object.prototype doesn't have cloneNode, but Element.prototype doesn't either.
那么,假设我的方法是正确的,我需要使用哪个类来覆盖 cloneNode?p>
So, which class do I need to use to override cloneNode, assuming my method is correct?
推荐答案
这一系列的工作正在进行中,但它重新实现了 cloneNode 的功能.http://jsfiddle.net/beCVL/19/
This series of fiddles is a work in progress, but it reimplements cloneNode's functionality. http://jsfiddle.net/beCVL/19/
截至美国东部时间 4 月 4 日上午 10:53,它需要与 IE 一起使用,因为 IE 没有 Node 对象.
as of April 4th, 10:53am EST, it needs to work with IE, as IE doesn't have a Node object.
注意,在 IE 中,原型函数不能被覆盖.因此,cloneNode 的所有实例都必须替换为一个确定要使用哪个版本的 cloneNode 的函数.
Note, that in IE, prototype functions can't be overridden. So, all instances of cloneNode have to be replaced by a function that determines which version of cloneNode to use.
