在功能的自动化测试中，经常会用到鼠标事件。在selenium中，我们主要借助的是action_chains模块中的ActionChains，使用该类要先进行导入，导入方式为：

from selenium.webdriver.common.action_chains import ActionChains

下面是详细源代码

1、鼠标悬浮操作

#/usr/bin/env python

#-*-coding:utf-8-*-

from selenium import webdriver

from selenium.webdriver.common.action_chains import ActionChains

import time as t

from selenium.webdriver.common.keys import Keys

driver=webdriver.Chrome()

driver.maximize_window()

driver.implicitly_wait(30)

driver.get(";)

#实例化ActionChains

actionChains=ActionChains(driver)

element=driver.find_element_by_link_text("设置")

#鼠标悬浮操作 move_to_element()

actionChains.move_to_element(element).perform()

t.sleep(3)

driver.find_element_by_link_text("搜索设置").click()

t.sleep(3)

driver.quit()

2、鼠标右键操作

#/usr/bin/env python

#-*-coding:utf-8-*-

from selenium import webdriver

from selenium.webdriver.common.action_chains import ActionChains

import time as t

from selenium.webdriver.common.keys import Keys

driver=webdriver.Chrome()

driver.maximize_window()

driver.implicitly_wait(30)

driver.get(";)

#实例化ActionChains

actionChains=ActionChains(driver)

element=driver.find_element_by_id("kw")

#鼠标右键操作context_click()

actionChains.context_click(element).perform()

t.sleep(3)

driver.quit()

3、鼠标右键

#/usr/bin/env python

#-*-coding:utf-8-*-

from selenium import webdriver

from selenium.webdriver.common.action_chains import ActionChains

import time as t

from selenium.webdriver.common.keys import Keys

driver=webdriver.Chrome()

driver.maximize_window()

driver.implicitly_wait(30)

driver.get(";)

#实例化ActionChains

actionChains=ActionChains(driver)

driver.find_element_by_id("kw").send_keys('seleniun')

element=driver.find_element_by_id("su")

#鼠标双击操作double_click()

actionChains.double_click(element).perform()

t.sleep(3)

driver.quit()

4、键盘事件实战

#/usr/bin/env python

#-*-coding:utf-8-*-

from selenium import webdriver

from selenium.webdriver.common.action_chains import ActionChains

import time as t

from selenium.webdriver.common.keys import Keys

driver=webdriver.Chrome()

driver.maximize_window()

driver.implicitly_wait(30)

driver.get(";)

# #实例化ActionChains

actionChains=ActionChains(driver)

re=driver.find_element_by_id('kw')

re.send_keys('Selenium')

#选中搜索框的关键字ctrl+a

re.send_keys(Keys.CONTROL,'a')

t.sleep(3)

#复制搜索框的关键字ctrl+c

re.send_keys(Keys.CONTROL,'c')

t.sleep(3)

#按下Backspace删除搜索关键字

re.send_keys(Keys.BACKSPACE)

t.sleep(3)

#打开Bing搜索首页

driver.get(';)

Bre=driver.find_element_by_id('sb_form_q')

#复制关键字到bing搜索框ctrl+v

Bre.send_keys(Keys.CONTROL,'v')

t.sleep(3)

driver.quit()
