selenium鼠標操作篇：鼠標懸停和偏移、拖動、長按

一、鼠標懸停
ActionChains對象調用move_to_element(元素），然后執行perform()
示例：

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common import action_chains

driver = webdriver.Firefox()
# 打開百度首頁
driver.get("https://www.baidu.com")
# 定位首頁的設置按鈕
ele_setting = driver.find_element(By.XPATH, "//span[@id='s-usersetting-top']")
# 實例化ActionChains對象，並傳入driver
action = action_chains.ActionChains(driver)
# 將鼠標懸停在設置按鈕處
action.move_to_element(ele_setting).perform()

示例的最終效果為，鼠標停留在按鈕元素處

 

二、鼠標偏移
ActionChains對象調用move_to_element_off_offset(元素未知，x，y)，然后執行perform()
示例:

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common import action_chains

driver = webdriver.Firefox()
# 打開百度首頁
driver.get("https://www.baidu.com")
# 定位首頁的設置按鈕
ele_setting = driver.find_element(By.XPATH, "//span[@id='s-usersetting-top']")
ele_login = driver.find_element(By.XPATH, "//a[@class='s-top-login-btn c-btn c-btn-primary c-btn-mini lb']")
s_location = ele_setting.location
l_location = ele_login.location
# 實例化ActionChains對象，並傳入driver
action = action_chains.ActionChains(driver)
# 將鼠標懸停在設置按鈕處
action.move_to_element_with_offset(ele_setting,
                                   s_location["x"]-l_location["x"],
                                   s_location["y"]-l_location["y"]).perform()

 

三、鼠標長按
鼠標長按：ActionChains對象調用click_and_hold()方法，然后調用perform()執行。

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common import action_chains

driver = webdriver.Firefox()
# 打開百度首頁
driver.get("https://www.baidu.com")
# 定位首頁的設置按鈕
ele_setting = driver.find_element(By.XPATH, "//span[@id='s-usersetting-top']")
# 實例化ActionChains對象，並傳入driver
action = action_chains.ActionChains(driver)
# 鼠標長按設置按鈕
action.click_and_hold(ele_setting)

 

四、鼠標拖動
拖動：
1，drag_and_drop(soure=起始元素, target=結束元素)
2，drag_and_drop_by_offset(soure=起始元素，xoffset，yoffset)，其中xoffset是水平便宜了，yoffset是垂直偏移量。
