selenium+chromeDriver配合使用（运行js脚本）

在python中调用selenium，访问百度，并运行js脚本爬取内容

python入口程序

from selenium import webdriver
import time

with open('./test.js', 'r',encoding='utf-8',errors='ignore') as f:
    str = f.read()
print(str)

brower = webdriver.Chrome()

brower.maximize_window()  # 最大化浏览器

brower.get("https://www.baidu.com")  # 通过get()方法，打开一个url站点
time.sleep(3)
clientWidth = brower.execute_script(str)

print('--------------------')
print(clientWidth)

with open('./test2.js', 'r',encoding='utf-8',errors='ignore') as f:
    str2 = f.read()
print(str2)
time.sleep(4)
txt = brower.execute_script(str2)
print('-----txt---------------')
print(txt)

test1.js

let height = document.body.offsetHeight;
document.getElementById('kw').value = '你好中国333';
document.getElementById('su').click();

return height

test2.js

let result = Array.from(document.querySelectorAll('#content_left h3')).map((el) => (el.innerText));
return result;
