动作链

三种实现拖拽功能的方式

from selenium import webdriver
from selenium.webdriver import ActionChains
from selenium.webdriver.support.wait import WebDriverWait  # 等待页面加载某些元素
from selenium.webdriver.common.by import By
from selenium.webdriver.edge.service import Service

ser = Service()
ser.path = r'.\chromedriver.exe'

driver = webdriver.Chrome(service=ser)
driver.get("http://www.runoob.com/try/try.php?filename=jqueryui-api-droppable")
driver.implicitly_wait(10)
driver.maximize_window()

try:
    driver.switch_to.frame('iframeResult')  ##切换到iframeResult
    sourse = driver.find_element(By.ID, 'draggable')
    target = driver.find_element(By.ID, 'droppable')

    '''拿到actions对象后，对象有很多方法
        1 把标签1 拖动到标签2上
            actions.drag_and_drop(标签1,标签2) 
        2 一点点滑动某个标签
            actions.click_and_hold(标签1).perform()
            actions.move_by_offset(x,y) # 把标签1 滑动x轴和y轴的距离
        3 滑动某个标签，一些距离
            actions.drag_and_drop_by_offset(标签1,x,y)
    '''

    # 方式一：基于同一个动作链串行执行
    actions = ActionChains(driver)  # 拿到动作链对象
    actions.drag_and_drop(sourse, target)  # 把动作放到动作链中，准备串行执行
    actions.perform()

    # 方式二：不同的动作链，每次移动的位移都不同
    # ActionChains(driver).click_and_hold(sourse).perform()  # 鼠标点中源标签 不松开
    # distance=target.location['x']-sourse.location['x']
    # track = 0
    # while track < distance:
    #     ActionChains(driver).move_by_offset(xoffset=10, yoffset=0).perform()
    #     track += 10
    # ActionChains(driver).release().perform()

    # 方式三：
    # actions = ActionChains(driver)
    # actions.drag_and_drop_by_offset(sourse, 200, 0).perform()
    #
    # time.sleep(5)

finally:
    driver.close()
