鼠标表示鼠标事件。 鼠标操作是通过使用低级界面执行的，该界面允许我们向Web浏览器提供虚拟化的设备输入操作。

鼠标动作操作方法详细介绍如下：
click_and_hold
移动到该元素，然后在给定元素的中间单击（不释放）
import time
from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
with webdriver.Chrome() as driver:
driver.get('https://www.baidu.com/')
time.sleep(2)
setting = driver.find_element_by_xpath('//*[@id="s-usersetting-top" and text()="设置"]')
ActionChains(driver).click_and_hold(setting).perform()
time.sleep(5)
context_click
首先将鼠标移动到元素的位置，然后在给定元素上执行上下文单击（右键单击）
import time
from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
with webdriver.Chrome() as driver:
driver.get('https://www.runoob.com/python/python-tutorial.html')
time.sleep(2)
setting = driver.find_element_by_xpath('//*[@rel="noopener noreferrer" and text()="Python 3.X 版本的教程"]')
ActionChains(driver).context_click(setting).perform()
time.sleep(5)
double_click
移动到该元素，并在给定元素的中间双击
import time
from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
with webdriver.Chrome() as driver:
driver.get('https://www.runoob.com/python/python-tutorial.html')
time.sleep(2)
setting = driver.find_element_by_xpath('//*[@rel="noopener noreferrer" and text()="Python 3.X 版本的教程"]')
ActionChains(driver).double_click(setting).perform()
time.sleep(5)
move_to_element
将鼠标移到元素的中间。 执行此操作时，该元素也会滚动到视图中，再进行定位操作
import time
from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
with webdriver.Chrome() as driver:
driver.get('https://www.baidu.com/')
setting = driver.find_element_by_xpath('//*[@id="s-usersetting-top" and @name="tj_settingicon"]')
ActionChains(driver).move_to_element(setting).perform()
driver.find_element_by_xpath('//*[text()="搜索设置"]').click()
time.sleep(5)
move_by_offset
将鼠标从其当前位置（或0,0）移动给定的偏移量。 如果坐标在视图窗口之外，则鼠标将最终在浏览器窗口之外
import time
from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
with webdriver.Chrome() as driver:
driver.get('https://www.baidu.com/')
setting = driver.find_element_by_xpath('//*[@id="s-usersetting-top" and @name="tj_settingicon"]')
ActionChains(driver).move_to_element(setting).perform()
time.sleep(5)
xOffset = 1
yOffset = 1
webdriver.ActionChains(driver).move_by_offset(xOffset, yOffset).perform()
driver.find_element_by_xpath('//*[text()="搜索设置"]').click()
time.sleep(5)
如我们把xOffset和yOffset的值稍微设置大一点，设置值为 100，就会报不在范围的错误：Message: move target out of bounds
/Users/lifeng/python-virtualenv/venv/bin/python3 /Users/lifeng/python-projects/test-python/selenium_script.py
Traceback (most recent call last):
File "/Users/lifeng/python-virtualenv/venv/lib/python3.9/site-packages/selenium/webdriver/remote/errorhandler.py", line 242, in check_response
raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.MoveTargetOutOfBoundsException: Message: move target out of bounds
(Session info: chrome=89.0.4389.82)
drag_and_drop
首先在源元素上单击并按住，然后移动到目标元素的位置，然后释放鼠标
import time
from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
with webdriver.Chrome() as driver:
driver.get('https://www.baidu.com/')
setting = driver.find_element_by_xpath('//*[@id="s-usersetting-top" and @name="tj_settingicon"]')
setting_one = driver.find_element_by_xpath('//*[@id="s-usersetting-top" and @name="tj_settingicon"]')
ActionChains(driver).drag_and_drop(setting, setting_one).perform()
driver.find_element_by_xpath('//*[text()="搜索设置"]').click()
time.sleep(5)
drag_and_drop中要传两个参数，传入第一个是源元素setting后按住，再点击传入的目标元素setting_one后，然后再释放掉setting_one
drag_and_drop_by_offset
首先在源元素上单击并按住，移至给定的偏移量，然后释放鼠标。可针对验证码滑动解锁操作
import time
from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
from selenium.common.exceptions import UnexpectedAlertPresentException
with webdriver.Chrome() as driver:
driver.get('https://mail.qq.com/')
time.sleep(2)
form_ = driver.find_element_by_xpath('//*[@id="login_frame"]')
driver.switch_to.frame(form_)
driver.find_element_by_xpath('//*[@id="u"]').click()
driver.find_element_by_xpath('//*[@id="u"]').send_keys('16688888888')
driver.find_element_by_xpath('//*[@id="p"]').click()
driver.find_element_by_xpath('//*[@id="p"]').send_keys('12345678999')
driver.find_element_by_xpath('//*[@id="login_button"]').click()
time.sleep(2)
code_iframe = driver.find_element_by_xpath('//*[@id="tcaptcha_iframe"]')
driver.switch_to.frame(code_iframe)
code_offset = driver.find_element_by_xpath('//*[@id="tcaptcha_drag_button"]')
ActionChains(driver).drag_and_drop_by_offset(code_offset, 179, 0).perform()
time.sleep(10)
官方文档中的介绍是可以这样操作：
from selenium import webdriver
driver = webdriver.Chrome()
driver.get("https://crossbrowsertesting.github.io/drag-and-drop")
sourceEle = driver.find_element(By.ID, "draggable")
targetEle = driver.find_element(By.ID, "droppable")
targetEleXOffset = targetEle.location.get("x")
targetEleYOffset = targetEle.location.get("y")
webdriver.ActionChains(driver).drag_and_drop_by_offset(sourceEle, targetEleXOffset, targetEleYOffset).perform()
但是实操使用了location.get()的方法，运行后报错了:
/Users/lifeng/python-virtualenv/venv/bin/python3 /Users/lifeng/python-projects/test-python/selenium_script.py
Traceback (most recent call last):
File "/Users/lifeng/python-projects/test-python/selenium_script.py", line 29, in <module>
xOffset = code_offset.location(170)
TypeError: 'dict' object is not callable
Process finished with exit code 1
release
将释放按下的鼠标左键
import time
from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
with webdriver.Chrome() as driver:
driver.get('https://www.runoob.com/python/python-tutorial.html')
text_python = driver.find_element_by_xpath('//*[@rel="noopener noreferrer" and text()="Python 3.X 版本的教程"]')
target_python = driver.find_element_by_xpath('//*[@rel="noopener noreferrer" and text()="Python 3.X 版本的教程"]')
webdriver.ActionChains(driver).click_and_hold(text_python).move_to_element(target_python).perform()
webdriver.ActionChains(driver).release().perform()
time.sleep(1)
