Question

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

但由于页面加载未完成，我的脚本每次都失败，产生以下错误：

因此我想在20秒之后停止页面加载，然后在我输入上面的代码时点击元素。因为我在页面开始加载时检查了如果我试图查看页面源，我没有得到任何web元素。但是在页面加载开始之后，如果我从开始关闭它到10-12秒，并尝试查看网页源代码，那里所有必需的元素。

所以我想用progamatically做同样的事情。知道怎么做吗？

在Selenium2 API中，默认情况下，没有选项可以停止页面加载。它将等待页面完成加载。

试用此代码：

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

以上代码将等待最多10秒的页面加载。如果页面加载退出时将抛出TimeoutException。你抓住了例外，满足了你的需求。我不确定天气会在抛出异常后退出页面加载。我还没有尝试这个代码。想要尝试一下。

反正有没有从浏览器停止页面加载？
