Zombie.js浏览器不返回完整的HTML？
我试图找出Zombie.js。
我有这个脚本：
var Browser = require("zombie"); var assert = require("assert"); Browser.visit("http://web.mit.edu", function (e,browser) { console.log(browser.html()); }); 这只是访问该页面，并logging的HTML，但我得到的HTML不符合我在一个正常的浏览器中得到的源文件。
Zombie.js输出：

真正的来源是很长的，请查看http://web.mit.edu
这是怎么回事？
如果你使用assert来比较源代码和僵尸的结果，你会得到一个错误，因为以下几点：
首先browser.html()不会给你的文档types。
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
第二和更重要的麻省理工学院使用JavaScript文件，在一秒钟超时后加载
<script type="text/javascript"> setTimeout(function(){var a=document.createElement("script"); var b=document.getElementsByTagName('script')[0]; a.src=document.location.protocol+"//dnn506yrbagrg.cloudfront.net/pages/scripts/0011/6778.js"; a.async=true;a.type="text/javascript";b.parentNode.insertBefore(a,b)}, 1); </script>
或asynchronous
var _gaq = _gaq || []; _gaq.push( ['_setAccount', 'UA-1592615-11'], ['_trackPageview','/'], ['rollup._setAccount', 'UA-31439876-1'], ['rollup._trackPageview', '/mit/www/'] ); (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s); })();
源代码显示你加载它们的代码，而zombie给你的结果
<script src="http://dnn506yrbagrg.cloudfront.net/pages/scripts/0011/6778.js" type="text/javascript"></script>
和
<script type="text/javascript" src="http://www.google-analytics.com/ga.js"></script>
根据这些脚本的内容，他们可能会进一步改变DOM和僵尸显示更多的偏差。 不幸的是我不知道解决方法。
