动作链ActionChains

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
import time

driver = webdriver.Chrome()
driver.get('http://www.runoob.com/try/try.php?filename=jqueryui-api-droppable')
wait = WebDriverWait(driver, 3)
# driver.implicitly_wait(3)  # 使用隐式等待

try:
    driver.switch_to.frame('iframeResult')  # 切换到iframeResult
    sourse = driver.find_element_by_id('draggable')
    target = driver.find_element_by_id('droppable')

    # 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()
    distance = target.location['x'] - sourse.location['x']

    track = 0
    while track < distance:
        ActionChains(driver).move_by_offset(xoffset=2, yoffset=0).perform()

        # ActionChains(driver).move_by_offset()  # 移动x轴和y轴的距离
        # ActionChains(driver).move_to_element()  # 直接移动到某个控件上
        # ActionChains(driver).move_to_element_with_offset()  # 移动到某个控件的某个位置
        # 所有的动作最后都要执行perform(),真正的去执行
        track += 2
    
    # 释放动作链
    ActionChains(driver).release().perform()

    time.sleep(10)
