require 'rubygems'
require 'selenium-webdriver'
require 'win32ole'

driver = Selenium::WebDriver.for :firefox
driver.manage.timeouts.implicit_wait = 10
driver.get "https://prod.example.com/"
link_name = wait.until {

    element = driver.find_element(:link_text, "Company")
    element if element.displayed?
}

link_name.click if link_name

但是由于页面加载未完成，我的脚本每次都会失败，产生以下错误：

因此，我希望在 20 秒后停止页面加载，然后像我在上面的代码中输入的那样点击元素。因为如果我尝试查看页面源，我检查了页面何时开始加载，我没有得到任何网络元素。但是在页面加载开始后，如果我从开始到 10-12 秒关闭它，并尝试查看网页源代码，那里有所有必需的元素。

所以我想在程序上做同样的事情。知道怎么做吗？

在 Selenium2 API 中，默认情况下没有停止页面加载的选项。它将等待页面完成加载。

试试这个代码：

  driver.manage().timeouts().pageLoadTimeout(10, TimeUnit.SECONDS);

上面的代码将等待页面加载长达 10 秒。如果页面加载退出时间，它将抛出TimeoutException. 您捕获异常并满足您的需求。我不确定它是否会在抛出异常后退出页面加载。我还没有尝试过这段代码。想试一试。

了解更多信息。
