使用Watir Webdriver滚动Firefox
[英]Scroll Firefox using Watir Webdriver
问题描述
I'd like to scrape a website that dynamically generates more content as I scroll down the web browser. 
当我向下滚动浏览器时，我想抓一个动态生成更多内容的网站。 I have seen a related post, Auto-Scroll in FireFox , but it doesn't answer my question. 我在FireFox中看过一篇相关文章Auto-Scroll ，但它没有回答我的问题。
Is it possible to scroll a webpage until the end of page (no more content is generated by the web server) or until a few refreshes using Watir web-driver? 是否可以滚动网页直到页面结束（Web服务器不再生成内容）或直到使用Watir Web驱动程序刷新一些内容？

I have recently tried to do something like that, and to my surprise looks like webdriver does not have support for scrolling. 我最近尝试过这样的事情，令我惊讶的是，webdriver似乎不支持滚动。 I did find two workarounds. 我找到了两个解决方法。
This will send space to the browser, and it will scroll down (works on twitter.com, for example): 这将向浏览器发送space ，它将向下滚动（例如，在twitter.com上工作）：
browser.send_keys :space
This will scroll to the element, and if the element is at the bottom of the page, it will load more content: 这将滚动到元素，如果元素位于页面底部，它将加载更多内容：
browser.element.wd.location_once_scrolled_into_view
