Handle switch 1

   Sometimes when we use selenium, simulated in a click, a new window or a new tab will appear. However, at this time, our driver did not update the login window when analog or start page (in fact, is a handle, "handle is a special smart pointer", the handle to the beginning of the page). However, when I click action occurs, switch pages happen, but still handle original handle, then we need to switch operating handles to adjust to the new interface appears. Specific operation is as follows:

next_click.click()  # 模拟点击下一页的时候，会出现一个新窗口或者新标签
n = drive.window_handles  # 这个时候会生成一个新窗口或新标签页的句柄，代表这个窗口的模拟driver
print('当前句柄: ', n)  # 会打印所有的句柄
drive.switch_to_window(n[-1])  # driver切换至最新生产的页面

2.1 to access the contents of a tab under properties

For example, I want to get this python clicks at url:

url = drive.find_element_by_xpath(').get_attribute('href')  # 获取某一页中的，某个标签下某个属性的内容

2.2 turn off the current window, tab

The current drive handle is that you need to close the window, tab page:

drive.close()  # 注： 当前drive的句柄是你需要关闭窗口、标签页的

2.3 simulated mouse verification sliding bar

Sometimes, a simple question will meet verification slider, like this:

At this point, need to simulate sliding a mouse, refer to the following:

slider = drive.find_element_by_xpath('***')  # 滑动条那个小块的位置

velocity = [5, 6, 19, 40, 40, 50]  # 150长度， 根据进度条的长度，来设置滑动距离
ActionChains(drive).click_and_hold(slider).perform()  # 点击滑块，并保持
  for v in velocity:
      c = random.randint(0, 2)  # 为了反反爬虫，设计不定操作
      v = v+c  # 加入不定因素
      ActionChains(drive).move_by_offset(xoffset=v, yoffset=0).perform()  # 按照预先设计速率滑动
ActionChains(drive).release().perform()  # 释放
