独立的Javascript布局引擎？ [英] Standalone Javascript layout engine?
问题描述
$ b
有没有一种方法可以自己渲染它？
例如，在极端情况下，假设我正在访问一个网站几乎没有任何内容，但通过一系列Javascript函数显示非常丰富的TEXT内容（显然导致HTML）。
访问/读取HTML结果的方式如何？
我试图在Android上这样做。

但是，如果你看看实际的源代码（你在HttpResponse中得到了什么），你会看到更多的怪异文本......主要是javascript。
I我只对这个Javascript的结果感兴趣。任何想法如何做到这一点？
我认为答案是肯定的，但不要那样做。
如果我必须实施将'Facebook'翻译成手机的解决方案，我可以使用浏览器自动化解决方案在亚马逊EC2上安装服务器并运行浏览器，例如 Watir 来模拟点击并从页面上删除数据。我认为这是太多的希望，因为你可以在手机本身背后高效运行。
然而，更好的解决方案可能是使用Firebug / Fiddler等对发送的ajax调用进行反向工程并找到获取底层数据的方法？或者，也许你只需要反向工程JS：（。
Assuming I retrieved HTML content from a website (over which I have no control), and that content contains lots of Javascript code that's a significant part of what's actually rendered by a layout engine (e.g. WebView).
Is there a way I can render it myself?
For example, in the extreme case, suppose I am visiting a website that has almost nothing in its but displays very rich TEXT content, via a host of Javascript functions (which obviously results in HTML).
How do access/read that HTML result?
I am looking to do this on Android only.
Update, trying to provide more context to @abesto. If you go to facebook.com and copy/paste rendered content into a text file, you'll receive:

But if you look at the actual source (what you get in HttpResponse) you'll see much more monstrous text... mostly javascript.
I am only interested in the result of that Javascript. Any ideas how to accomplish this?
I think the answer is yes, but don't do that.
If I had to implement a solution for translating 'Facebook' to a mobile phone, I could set up a server, maybe on Amazon EC2 and run the browser there, using a browser automation solution, such as Watir to simulate the clicks and scrape the data off the page. I think it's too much to hope for that you could run that efficiently behind the scenes on the phone itself.
However, the better solution might be to use Firebug/Fiddler etc to reverse engineer the ajax calls being sent and find a way to get the underlying data? Or maybe you just need to reverse-engineer the JS :(.
