WebDriver元素（三）

1.常用的键盘操作：

    send_keys(Keys.BACK_SPACE)    删除键（BackSpace)

    send_keys(Keys.SPACE)              空格键（Space)

    send_keys(Keys.TAB)                 制表键（Tab）

    send_Keys(Keys.CONTROL,'a')    全选（Ctrl+A)

from  selenium import webdriver

from selenium.webdriver.common.keys  import Keys

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

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


driver.find_element_by_id("kw").send_keys(Keys.BACK_SPACE)
driver.find_element_by_id("kw").send_keys(Keys.SPACE)#输入空格键

2.获得验证信息

from selenium import webdriver
import time

driver = webdriver.Firefox()
driver.get("http://www.126.com")

print('Before login==========')

title = driver.title
print(title)

now_url = driver.current_url
print(now_url)
#执行邮箱登录
driver.find_element_by_id("idInput").clear()
driver.find_element_by_id("idInput").send_keys("username")
driver.find_element_by_id("pwdInput").clear()
driver.find_element_by_id("pwdInput").send_keys("password")
driver.find_element_by_id("loginBtn").click()
time.sleep(5)

print('After login===========')

#再次打印当前页面title
title = driver.title
print(title)

#打印当前页URL
now_url = driver.current_url
print(now_url)

#获得登录的用户名
user = driver.find_element_by_id('spnUid').text
print(user)

driver.quit()

 title:用户获得当前页面的标题

current_url:用户获得当前页面的URL

3.设置元素等待：

WebDriver提供了两种等待：显示等待和隐式等待
