如何使用硒将网页滚动到目标元素 [英] How to Scroll web page to the target element using selenium

问题描述

我想滚动到硒元素，但我希望它位于页面顶部，而不仅仅是在页面上可见.

I want to scroll to an element in selenium, but I want it to be at the top of the page, not just visible on the page.

如何使页面滚动，以便滚动到的元素位于浏览器的顶部?

How can I make it so that the page scrolls such that the element being scrolled to is at the top of the browser?

target = browser.find_element_by_css_selector(".answers-wrap")
actions = ActionChains(browser)
actions.move_to_element(target)
actions.perform()

推荐答案

以下是我们使用此页面的示例

要将网页垂直滚动1000像素，请使用 execute_script("window.scrollBy(0,1000)")

示例

import time
from selenium import webdriver

chrome_browser = webdriver.Chrome()
chrome_browser.get('https://stackoverflow.com/questions/61071131/'
                   'scroll-in-selenium-driver-to-make-element-at-top-of-the-page')
time.sleep(4)
''' execute_script("window.scrollBy(x-pixels,y-pixels)")
    scroll down the page by  1000 pixel vertical
'''
chrome_browser.execute_script("window.scrollBy(0,1000)")

execute_script("window.scrollBy(x-pixels,y-pixels)")

execute_script("window.scrollBy(x-pixels,y-pixels)")

_{x-pixels是x轴上的数字，如果number为正数则向左移动，如果number为负数则向右移动.y-pixels是y轴上的数字. ，如果数字为正，则向下移动；如果数字为负，则向上移动.}

将网页向下滚动到目标元素.

execute_script("arguments[0].scrollIntoView();", element)

execute_script("arguments[0].scrollIntoView();", element)

参数[0]"表示页面的第一个索引从0开始.

代码示例

import time
from selenium import webdriver

chrome_browser = webdriver.Chrome()
chrome_browser.get('https://stackoverflow.com/questions/61071131/'
                   'scroll-in-selenium-driver-to-make-element-at-top-of-the-page')
time.sleep(4)

element = chrome_browser.find_element_by_css_selector(
    "#footer > div > nav > div:nth-child(1) > h5 > a")

chrome_browser.execute_script("arguments[0].scrollIntoView();", element)
