Timers in the jsdom (set by window.setTimeout() or window.setInterval()) will, by definition, execute code in the future in the context of the window. Since there is no way to execute code in the future without keeping the process alive, outstanding jsdom timers will keep your Node....
var definition = current_abbr.getAttribute("title"); var key = current_abbr.lastChild.nodeValue; defs[key] = definition; } // create the definition list var dlist = document.createElement("dl"); // loop through the definitions for (key in defs) { var definition = defs[key]; // creat...
其次,在负责创建“缩略语列表“的那个for循环后面添加这样一条语句: //遍历定义for(keyindefs){vardefinition =defs[key];//创建定义列表vardtitle = document.createElement("dt");vardtitle_text =document.createTextNode(key); dtitle.appendChild(dtitle_text);//创建定义描述varddesc = document.createElement...
defs[key]=definition; } //创建定义列表 var dlist=document.createElement("dl"); //遍历缩略语数组defs for(key in defs){ //为每一个创建定义标题dt对应key var dtitle=document.createElement("dt"); var dtitle_text=document.createTextNode(key); ...

在Javascript对象中,虚拟DOM 表现为一个 Object对象。并且最少包含标签名 (tag)、属性 (attrs) 和子元素对象 (children) 三个属性,不同框架对这三个属性的名命可能会有差别 创建虚拟DOM就是为了更好将虚拟的节点渲染到页面视图中,所以虚拟DOM对象的节点与真实DOM的属性一一照应 ...

jsdom is a pure-JavaScript implementation of many web standards, notably the WHATWGDOMandHTMLStandards, for use with Node.js. In general, the goal of the project is to emulate enough of a subset of a web browser to be useful for testing and scraping real-world web applications. ...
Vdom: definition of the VDOM tree and of "virtual applications". This is a "pure" module, which does not depend on any Javascript bindings (it could be executed on the server-side, e.g. for automated testing). Vdom_blit: rendering of virtual applications into the actual DOM. This module...
