创建一个 HTMLCollection

我正在尝试垫片Element.prototype.children http://www.w3.org/TR/domcore/#dom-element-children应该返回一个HTML集合 http://www.w3.org/TR/domcore/#htmlcollection

有一个window.HTMLCollection https://developer.mozilla.org/en/DOM/HTMLCollection

However

var h = new HTMLCollection();
//TypeErrror: HTMLCollection is not a constructor

and

var h = Object.create(HTMLCollection.prototype);
h[0] = div;
h.item(0); 
// Could not convert JavaScript argument

测试 Firefox 7 和 Chrome

除了垫片之外HTMLCollection有什么办法可以与之互动吗？

还提供反馈这个 github 问题 https://github.com/Raynos/DOM-shim/issues/5如果你能提出一个解决方案

我认为这是创建 HTMLCollection 的正确方法，由浏览器处理。

var docFragment = document.createDocumentFragment();
docFragment.appendChild(node1);
docFragment.appendChild(node2);
var myHTMLCollection = docFragment.children;
