如何使用 selenium 将网页滚动到目标元素

How to Scroll web page to the target element using selenium(如何使用 selenium 将网页滚动到目标元素)

问题描述

我想滚动到 selenium 中的一个元素，但我希望它位于页面顶部，而不仅仅是在页面上可见.

我怎样才能使页面滚动以使滚动到的元素位于浏览器的顶部?

target = browser.find_element_by_css_selector(".answers-wrap")动作 = ActionChains(浏览器)actions.move_to_element(目标)动作.执行()

这是使用我们所在页面的示例

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

例子

导入时间从硒导入网络驱动程序chrome_browser = webdriver.Chrome()chrome_browser.get('https://stackoverflow.com/questions/61071131/''在页面顶部滚动硒驱动程序以制作元素')时间.sleep(4)''' execute_script("window.scrollBy(x-pixels,y-pixels)")垂直向下滚动页面 1000 像素'''chrome_browser.execute_script("window.scrollBy(0,1000)")

<块引用>

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

_{x-pixels 是 x 轴上的数字，如果数字是正数，它会向左移动，如果数字是负数，它会向右移动.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.}

向下滚动网页到目标元素.

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

"arguments[0]" 表示页面的第一个索引从 0 开始.

代码示例

导入时间从硒导入网络驱动程序chrome_browser = webdriver.Chrome()chrome_browser.get('https://stackoverflow.com/questions/61071131/''在页面顶部滚动硒驱动程序以制作元素')时间.sleep(4)元素 = chrome_browser.find_element_by_css_selector("#footer > div > nav > div:nth-child(1) > h5 > a")chrome_browser.execute_script("arguments[0].scrollIntoView();", 元素)

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.

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()

Here is example using this page we are on

To scroll the web page by 1000 pixel vertical use execute_script("window.scrollBy(0,1000)")

Example

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)")

_{x-pixels is the number at x-axis, it moves to the left if number is positive and it move to the right if number is negative .y-pixels is the number at y-axis, it moves to the down if number is positive and it move to the up if number is in negative .}

To scroll down the web page to the target element.

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

"arguments[0]" means first index of page starting at 0.

Code example

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)
