1.python+selenium+Safari浏览器，定位元素

selenium.common.exceptions.ElementNotVisibleException: Message: An element command could not be completed because the element is not visible on the page.

在GitHub上有人提出过同样的问题，https://github.com/SeleniumHQ/selenium/issues/5355，有一个回答如下：

可以参考https://bugs.webkit.org/show_bug.cgi?id=174710，这个bug在Safari开发版已经修复，但并未发布。

那么怎么解决Safari浏览器的点击问题呢？

解决方法如下：

通过调用js的方法进行操作

execute_script(script, *args)

#Example：

ele = browser.find_element_by_xpath('//*[@id="1$Menu"]/li')

browser.execute_script('arguments[0].click();', ele)

2.python3+selenium 3.13 + geckodriver 21.0，提示ConnectionResetError，切换为较低版本的driver即可

学习selenium时，如果sleep时间大于等于5秒，就会提示ConnectionResetError: [Errno 54] Connection reset by peer。

换成chrome浏览器，可以正常运行。

demo.py

from selenium import webdriver

from time import sleep, ctime

#chrome

#driver = webdriver.Chrome(executable_path='//Users/csj/Desktop/seleniumdriver/chromedriver/chromedriver')

#Firefoxdriver 21.0

driver = webdriver.Firefox(executable_path='//Users/csj/Desktop/seleniumdriver/firefoxdriver/21.0/geckodriver')

#Firefoxdriver 20.1

#driver = webdriver.Firefox(executable_path='//Users/csj/Desktop/seleniumdriver/firefoxdriver/20.1/geckodriver')

#Firefoxdriver 20.0

#driver = webdriver.Firefox(executable_path='//Users/csj/Desktop/seleniumdriver/firefoxdriver/20.0/geckodriver')

#Firefox 19.1

#driver = webdriver.Firefox(executable_path='//Users/csj/Desktop/seleniumdriver/firefoxdriver/19.1/geckodriver')

driver.implicitly_wait(10)

driver.get("http://www.baidu.com")

print(ctime())

sleep(5)

print(ctime())

driver.find_element_by_id("kw").send_keys("selenium")

driver.close()

使用Firefoxdriver 21.0，报如下错误：

ConnectionResetError: [Errno 54] Connection reset by peer

换成chrome，可以正常运行。老板提醒可能是版本的问题，分别用 Firefox 20.1, 20.0, 19.1,均能运行成功，没有再提示ConnectionResetError。

休眠时间设置为10秒，也没有再报错。
