例如有些地方需要使用到双击修改信息等，就需要使用到鼠标双击模拟操作
from selenium import webdriver
from selenium.webdriver import ActionChains
action_chains = ActionChains(self.driver)
action_chains.double_click(self.driver.find_element(By.ID,"span_shorturl")).perform()
2、右键单击
例如右键之后会出现菜单
from selenium import webdriver
from selenium.webdriver import ActionChains
action_chains = ActionChains(self.driver)
action_chains.
context_click
(self.driver.find_element(By.ID,"span_shorturl")).perform()
3、鼠标悬停
from selenium import webdriver
from selenium.webdriver import ActionChains
action_chains = ActionChains(self.driver)
action_chains.move_to_element(self.driver.find_element(By.ID,"span_shorturl")).perform()
4、鼠标拖动：比如 拖动某个对象、拖动滚动条
#定位元素的源位置
source = driver.find_element_by_id("id")
#定位元素要移到到的目标位置
target = driver.find_element_by_id("id")
action_chains = ActionChains(self.driver)
action_chains .drag_and_drop(source,target).perform()
