CSS常用定位方法

1. find_element_by_css_selector（）
2. #id id选择器根据id属性来定位元素
3. .class  class选择器，根据class属性值来定位元素
4. [attribute='value'] 根据属性来定位元素
5. element>element 根据元素层级来定位 父元素>子元素

from selenium import webdriverfrom time import sleepdriver = webdriver.Chrome()driver.get("https://www.baidu.com/")#根据 class 定位driver.find_element_by_css_selector(".s_ipt").send_keys("你好")#根据id 定位driver.find_element_by_css_selector("#kw").send_keys("你好2")#根据属性定位driver.find_element_by_css_selector("[autocomplete='off']").send_keys("11")sleep(2)driver.get("https://www.baidu.com/")driver.find_element_by_css_selector(".s_ipt").send_keys("51zixuewang")sleep(1)driver.find_element_by_partial_link_text("我要自学网-视频教程").click()sleep(1)#根据层级定位driver.find_element_by_css_selector("form#loginForm>ul>input[type='password']").send_keys("51zxw")

下拉菜单元素定位

from selenium.webdriver.support.ui import Select

from selenium import webdriverfrom selenium.webdriver.support.ui import Selectfrom time import sleepdriver = webdriver.Chrome()driver.get("http://www.51zxw.net")select = Select(driver.find_element_by_css_selector("[name='CookieDate']"))sleep(1)select.select_by_index("1")sleep(3)select.select_by_value("1")sleep(3)select.select_by_visible_text("留一年")
