Question

我正在尝试在node.js中使用jsdom来对HTML文档进行小的转换。在进行客户端测试时，我使用了document.createTreeWalker和document.createNodeIterator函数，这些函数是part of the DOM 2 specification ...但是，它们显然不是jsdom的一部分，尽管它的作者声称它具有完整的DOM1和DOM2兼容性。我错过了什么吗？这些功能是否在jsdom创建的文档中可用？

$ node
> var jsdom = require('jsdom');
> var doc = jsdom.jsdom('<div>Test</div><div>One</div><div>Two</div>');
> doc.createTreeWalker(doc)
TypeError: Object [ null ] has no method 'createTreeWalker'
