import time

def open_new_url(url):
    # 就在当前标签页打开网页
    driver.execute_script("window.open('"+url+"', '_blank');")

    # 获取所有窗口句柄并切换到最后一个
    handles = driver.window_handles
    driver.switch_to.window(handles[-1])

def scroll_page(driver):
    for i in range(1,21):
        dest = str(i/20)
        driver.execute_script("window.scrollTo(0, document.body.scrollHeight*"+dest+");")
        time.sleep(0.5)

if __name__ == '__main__':
	
    # 指定驱动路径
    driver_path = '/opt/soft/chromedriver-linux64/chromedriver'
    # 创建Service对象并传入ChromeOptions
    service = Service(driver_path)
    # 得到options
    chrome_options = Options()
    chrome_options.add_experimental_option("debuggerAddress", "127.0.0.1:9222")
    driver = webdriver.Chrome(options=chrome_options,service=service)
    # 通过JavaScript在新窗口打开URL
