如何提取HTML文档中的javascript链接? [英] How to extract javascript links in an HTML document?

问题描述

我正在为一个使用网站上很多JavaScript的网站编写一个小型Webspider:

I am writing a small webspider for a website which uses a lot of javascript for links:

<htmlTag onclick="someFunction();">Click here</htmlTag>

函数如下:

function someFunction() {
  var _url;
  ...
  // _url constructed, maybe with reference to a value in the HTML doc
  // and/or a value passed as argument(s) to this function
  ...
  window.location.href = _url;
}

在服务器端评估此功能的最佳方法是什么，以便我可以构造_url的值?

What is the best way of evaluating this function server-side so I can construct the value for _url?

推荐答案

您还可以使用 env.js 和 rhino 来实际评估html中的JavaScript并检测更改手动触发click事件后，将其定位到位置对象.

You could also use env.js and rhino to actually evaluate the JavaScript in the html and detect changes to the location object after manually firing a click event.
