动作链 selenium的ActionChains
selenium 执行JS代码  JavaScript  execute_script()
获取节点信息

from selenium import webdriver
from selenium.webdriver import ActionChains
browser = webdriver. Chrome()
url = ‘https://www.zhihu.com/explore‘
browser.get ( url)
# logo= browser.find_element_by_id (‘zh-top-link-logo‘)
# print(logo)  #
# print(logo.get_attribute(‘class‘ ))
input = browser.find_element_by_class_name(‘zu-top-add-question‘)  #WebElement
print(input.text)
print(input.id)     #
print(input.location) #位置
print(input.tag_name) #标签名
print(input.size)     #尺寸
# 获取id 位置 标签名 大小
# WebElement节点还有些其他属性，比如 id 属性可以获取节点 id ,location 属性可以获
# 取该节点在页面中的相对位置， tag_name 属性可以获取标签名称， size 属性可以获取节点的大小，也
# 就是宽高
