selenium相关操作

1.selenium相关操作

from selenium import webdriver
import time


brower = webdriver.Chrome(executable_path='./chromedriver.exe') # 引入chrome驱动
brower .maximize_window() # 窗口最大化
brower .get('https://www.taobao.com/') # get方式请求淘宝
time.sleep(3)
search_input = brower .find_element_by_id('q') # 根据id找到淘宝搜索框
search_input.send_keys("iphone 手机壳") # 在框中输入搜索内容
brower .execute_script('window.scrollTo(0,document.body.scrollHeight)') # 执行js代码，滚动屏幕
btn = brower .find_element_by_css_selector('.btn-search') # 根据标签找到按钮
btn.click() # 点击
time.sleep(2)
brower .get("https://www.sogou.com/") 
time.sleep(2)
brower .back() # 页面后退
time.sleep(2)
brower .forward() # 页面前进
time.sleep(5)
brower .quit() # 退出浏览器

2.selenium中的iframe操作

如果定位的标签在iframe中，需要用bro.switch_to.frame(id)切换到指定id的iframe作用域中

from selenium import webdriver
from selenium.webdriver import ActionChains # 引包
import time
bro = webdriver.Chrome(executable_path='./chromedriver.exe')
bro.maximize_window()
bro.get('https://www.runoob.com/try/try.php?filename=jqueryui-api-droppable')
bro.switch_to.frame('iframeResult') # 切换浏览器标签的作用域
div = bro.find_element_by_id('draggable')
action = ActionChains(bro) # 实例化
action.click_and_hold(div) # 点击并保持
for i in range(5):
    # perform()立即执行动作链操作
    # move_by_offset(x,y); x 水平方向，y 竖直方向
    action.move_by_offset(14, 0).perform()
    time.sleep(0.3)
# 释放动作链
action.release()
bro.quit()
