ActionChains类：
context_click()右击
double_click()双击
drag_and_drop()拖动
鼠标的双击、右击、拖动等应该怎样写呢？例如右击：
driver.find_element_by_id(“xxx”).context_click()
经过运行脚本得到了下面的错误提示：
AttributeError:’WebElement’objecthasnoattribute’context_click’
提示右点方法不属于webelement对象，通过查找文档，发现属于ActionChains类，但文档中没有具体写法。
一、鼠标右击：#coding=utf-8from selenium import webdriverfrom selenium.webdriver.common.action_chains import ActionChainsimport timedriver = webdriver.Firefox()driver.get("?referrer=http%3A%2F%2Fwebcloud.kuaibo.com%2F")#登陆快播私有云driver.find_element_by_id("user_name").send_keys("username")driver.find_element_by_id("user_pwd").send_keys("123456")driver.find_element_by_id("dl_an_submit").click()time.sleep(3)#定位到要右击的元素qqq =driver.find_element_by_xpath("/html/body/div/div[2]/div[2]/div/div[3]/table/tbody/tr/td[2]")#对定位到的元素执行鼠标右键操作ActionChains(driver).context_click(qqq).perform()'''#你也可以使用三行的写法，但我觉得上面两行写法更容易理解chain = ActionChains(driver)implement = driver.find_element_by_xpath("/html/body/div/div[2]/div[2]/div/div[3]/table/tbody/tr/td[2]")chain.context_click(implement).perform()'''time.sleep(3) #休眠3秒driver.close()
二、鼠标双击：
#定位到要双击的元素qqq =driver.find_element_by_xpath("xxx")#对定位到的元素执行鼠标双击操作ActionChains(driver).double_click(qqq).perform()
三、鼠标拖拽：
#定位元素的原位置element = driver.find_element_by_name("source")#定位元素要移动到的目标位置target = driver.find_element_by_name("target")#执行元素的移动操作ActionChains(driver).drag_and_drop(element, target).perform()
