python - 作业未滚动到网页上的特定文本

Question

我有一个工作完美，除了滚动到这个元素://span[text()="Next Page"] on this page 。

当我手动滚动时，它往往会起作用。

我尝试解决滚动到此文本的问题:

element = driver.find_element_by_xpath('//span[text()="Next Page"]')
driver.execute_script("return arguments[0].scrollIntoView();", element)

以及:

clickMe = wait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, ('//span[text()="Next Page"]'))))
clickMe2 = driver.find_elements_by_xpath('//span[text()="Next Page"]')
actions = ActionChains(driver)
actions.move_to_element(clickMe2).click()
element = driver.find_element_by_xpath('//span[text()="Next Page"]')
element.location_once_scrolled_into_view
driver.execute_script("arguments[0].scrollIntoView();", clickMe2)

它会执行作业，然后在以下行给出错误:driver.execute_script("arguments[0].scrollIntoView();", clickMe2)

完整错误:

完整code

已更新。

我之前已经删除了这个:

#SCROLL_PAUSE_TIME = 0.5


#last_height = driver.execute_script("return document.body.scrollHeight")

#while True:

    #driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")


    #time.sleep(SCROLL_PAUSE_TIME)


    #new_height = driver.execute_script("return document.body.scrollHeight")
    #if new_height == last_height:
        #break
    #last_height = new_height

但是，它似乎滚动整个页面而不是滚动到该特定元素。这是:

clickMe = wait(driver, 15).until(EC.element_to_be_clickable((By.XPATH, ('//span[text()="Next Page"]'))))
element1 = driver.find_element_by_xpath('//span[text()="Next Page"]')
driver.execute_script("return arguments[0].scrollIntoView();", element1)

实际上，您正在向右滚动到所需的元素，但有一个导航面板(带有搜索栏、登录和立即加入按钮的导航面板)固定在顶部并覆盖了“下一步”按钮。您只需向上滚动一点即可使“下一步”按钮可见。尝试下面的代码:

from selenium.webdriver.common.keys import Keys

header = driver.find_element_by_tag_name('header')
driver.execute_script('arguments[0].hidden="true";', header)
element = driver.find_element_by_xpath('//span[text()="Next Page"]')
driver.execute_script("arguments[0].scrollIntoView();", element)
driver.find_element_by_tag_name('body').send_keys(Keys.UP)
element.click()
