python - 强制页面在新窗口中打开 selenium-web-driver python

Question

我如何强制在 selenium-web-driver python 中的新窗口中打开链接并切换到它提取数据并关闭它目前我正在使用以下代码

for tag in self.driver.find_elements_by_xpath('//body//a[@href]'):
            href = str(tag.get_attribute('href'))
            print href
            if not href:
                continue
            window_before = self.driver.window_handles[0]
            print window_before
            ActionChains(self.driver) \
                .key_down(Keys.CONTROL ) \
                .click(tag) \
                .key_up(Keys.CONTROL) \
                .perform()
            time.sleep(10)
            window_after = self.driver.window_handles[-1]
            self.driver.switch_to_window(window_after)
            print window_after
            time.sleep(10)
            func_url=self.driver.current_url
            self.driver.close()
            self.driver.switch_to_window(window_before)

问题

1. 如果上面的代码点击了带有

   的链接，则不会强制执行

   <a href="" target="_blank">something</a>

2. 经过两个链接后，它的打印内容变得陈旧

   StaleElementReferenceException: Message: The element reference is stale. Either the element is no longer attached to the DOM or the page has been refreshed.

Answer 1

您可以尝试以下方法在新窗口中打开链接:

current_window = self.driver.current_window_handle
link = self.driver.find_element_by_tag_name('a')
href = link.get_attribute('href')
if href:
    self.driver.execute_script('window.open(arguments[0]);', href)
else:
    link.click()
new_window = [window for window in self.driver.window_handles if window != current_window][0]
self.driver.switch_to.window(new_window)
# Execute required operations
self.driver.close()
self.driver.switch_to.window(current_window)

这应该允许您获取链接 URL 并使用 JavaScriptExecutor 在新窗口中打开它(如果它不是空字符串)，否则只需单击该链接。由于有问题的链接具有属性 target="_blank" ，它将在新窗口中打开
