一、示例HTML代码如下：

<!DOCTYPE html>
<html>
<head>
<style type="text/css">
div.scroll
{
background-color:#00FFFF;
width:100px;
height:100px;
overflow:auto;
}

</style>
</head>

<body>

<p>overflow:scroll</p>
<div class="scroll">You can use the overflow property when you want to have better control of the layout. The default value is visible.aaaaaaaaaaaaaaaaaaaaaaaaaaaa</div>

</body>
</html>

我们用JS来控制里面的滚动条滚动：

# -*- coding: utf-8 -*-

"""
@author: lucas
@Function:
@file: divRoll.py
@time: 2021/8/24 10:29 上午
"""
import unittest
from time import sleep

from selenium import webdriver


class DivRoll(unittest.TestCase):

    def setUp(self):
        self.driver = webdriver.Chrome()

    def test_div(self):
        driver = self.driver
        driver.get('file:///Users/leiyuxing/PycharmProjects/pythonProject4/htmlData/div.html')
        sleep(1)
        # 用JS来控制里面的滚动条滚动
        # document.getElementsByClassName("scroll")[0].scrollHeight  # 获取滚动条高度
        # document.getElementsByClassName("scroll")[0].scrollWidth  # 获取横向滚动条宽度
        # document.getElementsByClassName("scroll")[0].scrollLeft = xxx  # 控制横向滚动条位置
        js = 'document.getElementsByClassName("scroll")[0].scrollTop=10000'
        driver.execute_script(js)
        sleep(3)

    def tearDown(self):
        self.driver.close()


if __name__ == "__main__":
    unittest.main()

二、推荐三种兼容firefox、chrome、IE浏览器的js写法

$(window).scrollTop(300);

$(document).scrollTop(300)

$("html,body").scrollTop(300);

都是jQuery的写法，原生js怎么办：

document.body.scrollTop = 300; // FireFox  IE9+ 不可以

document.documentElement.scrollTop = 300; // Chrome 不可以 document.documentElement  === html
