如何使用watir滚动网页 [英] how to scroll a web page using watir

问题描述

我想滚动网页，以查找并点击在滚动页面时懒散加载的内容。我使用以下命令

I am trying to scroll a web page to find and click on a content that is lazily loaded when the page is scrolled. I am using following command

require 'watir-webdriver'

@browser = Watir::new :firefox
@browser.send_keys :space

我使用web-driver with firefox我在Ubuntu，但它不工作。在下面的ruby代码中，我试图向下滚动页面，直到我找不到与：id的元素。元素正在加载。
我在几秒钟后超时，任何想法下面的代码是什么问题。

I am using web-driver with firefox and I am on ubuntu but it is not working. In the following ruby code I am trying to scroll the page down until I don't find the element with :id. The element is loading lazily. I am getting timeout after few seconds, any idea what is wrong with the following code.

When /^deal (\d+) is loaded$/ do |id|
  (0..5).each do |click|    
    @browser.send_keys :space
  end
end

推荐答案

如果您启用了JavaScript，您可以访问底层驱动程序并执行一些JavaScript在页面上滚动。

If you have JavaScript enabled, you can access the underlying driver and execute some JavaScript to scroll on the page.

@browser.driver.executeScript("window.scrollBy(0,200)")

将沿着y轴向下滚动200像素。

will scroll down the page 200 pixels along the y axix.
