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 timefrom selenium import webdriverfrom selenium.webdriver.common.action_chains import ActionChainswith 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 timefrom selenium import webdriverfrom selenium.webdriver.common.action_chains import ActionChainswith 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 timefrom selenium import webdriverfrom selenium.webdriver.common.action_chains import ActionChainswith 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 timefrom selenium import webdriverfrom selenium.webdriver.common.action_chains import ActionChainswith 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 timefrom selenium import webdriverfrom selenium.webdriver.common.action_chains import ActionChainswith 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

import timefrom selenium import webdriverfrom selenium.webdriver.common.action_chains import ActionChainswith 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 timefrom selenium import webdriverfrom selenium.webdriver.common.action_chains import ActionChainsfrom selenium.common.exceptions import UnexpectedalertPresentExceptionwith 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 webdriverdriver = 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:
