使用Python在远程网站上触发Javascript事件 [英] Trigger Javascript event on remote website with Python

问题描述

我写了一些基本的Python代码来抓取远程网页并抓取一些数据。在我试图抓取的另一个页面上，数据在视图中隐藏，并且仅在更改< select> 框的值后才会显示。

I wrote some basic Python code to scrape a remote webpage and grab a few pieces of data. On a different page I'm trying to scrape, the data is hidden from view, and only appears after changing the value of a <select> box.

在通过远程网站的javascript进行去除和挖掘之后，我确认它正在使用AJAX（我认为是Prototype的自定义实现）来切换< tbody> < table> 我对抓取感兴趣。

After de-minifying and digging through the remote website's javascript, I confirmed that it is using AJAX (custom implementation of Prototype I think) to switch the <tbody> of the <table> I'm interested in scraping.

有没有办法使用Python（或通过Python的Javascript）来触发该选择框的onChange事件，这样我就可以刷新DOM并获取新的HTML？

Is there a way to use Python (or Javascript via Python) to trigger the onChange event of that select box so I can "refresh" the DOM and grab the new HTML?

推荐答案

找出AJAX请求URL并直接请求它。 ： - ）

Figure out the AJAX request URL and request it directly. :-)
