声明浏览器对象

browser = webdriver.Chrome()

访问页面

browser.get('https://www.baidu.com')

查找元素（还有其他方法）

input = browser.find_element_by_id('kw')

交互

# input.send_keys('Python')
# input.clear()
# input.send_keys('Java')
# input.send_keys(Keys.ENTER)

print(browser.page_source)
# print(browser.get_screenshot_as_png())
# print(browser.get_screenshot_as_file('qqq.png'))
# browser.close()

执行js

# browser.execute_script('window.scrollTo(0,document.body.scrollHeight)')
# browser.execute_script('alert("To Bottom")')

获取属性

# browser.get('https://www.zhihu.com/explore')
# logo = browser.find_element_by_id('zh-top-link-logo')
# print(logo)
# print(logo.get_attribute('class'))

获取文本

(注意 element 和elements的区别？后者的输出为list，然后遍历该list)

# browser.get('https://www.zhihu.com/explore')
# quess = browser.find_element_by_class_name('question_link')
# print(quess.text)
# print(quess.id)
# print(quess.location)
# print(quess.tag_name)
# print(quess.size)
# browser.back()
# browser.forward()
# browser.close()

# print(browser.get_cookies())

选项卡管理

# browser.get('https://www.zhihu.com/explore')
# browser.execute_script('window.open()')
# print(browser.window_handles)
# browser.switch_to_window(browser.window_handles[1])
# browser.get('https://www.zhihu.com/explore')
# browser.switch_to_window(browser.window_handles[0])
# browser.get('https://www.baidu.com')
