一 Selenium剩余部分

二 BeautifulSoup4

一 Selenium剩余部分
1.元素交互操作:
 ——点击、清除
 ——Actions Chains

 ——frame的切换

 ——执行js代码

from selenium import  webdriver
from selenium.webdriver import ActionChains
from selenium.webdriver.common.keys import Keys
import time

driver=webdriver.Chrome(r'C:\Users\Administrator\Desktop\chromedriver.exe')
try:
    driver.implicitly_wait(10)
    driver.get('https://www.runoob.com/try/try.php?filename=jqueryui-api-droppable')
    time.sleep(5)
    driver.switch_to.frame('iframeResult')
    time.sleep(1)
    source=driver.find_element_by_id('draggable')
    target=driver.find_element_by_id('droppable')
    print(source.size)
    print(source.tag_name)
    print(source.text)
    print(source.location)
    distance=target.location['x']-source.location['x']
    ActionChains(driver).click_and_hold(source).perform()

    s=0
    while s<distance:
        ActionChains(driver).move_by_offset(xoffset=2,yoffset=2).perform()
        s+=2
        time.sleep(0.1)
    ActionChains(driver).release().perform()
    time.sleep(10)
finally:
    driver.close()
