“百度一下按钮”
from selenium import webdriver driver = webdriver.Firefox() driver.get("https://www.baidu.com") #输入框ID定位 driver.find_element_by_id("kw").send_keys("python") #"百度一下“按钮 ID定位 driver.find_element_by_id("su").click()
from selenium import webdriver driver = webdriver.Firefox() driver.get("https://www.baidu.com") #输入框class name定位 driver.find_element_by_class_name("s_ipt").send_keys("python") #"百度一下“按钮 class 定位 driver.find_element_by_class_name("s_btn").click()
from selenium import webdriver driver = webdriver.Firefox() driver.get("https://www.baidu.com") #输入框 xpath属性层级 定位 driver.find_element_by_xpath("//span[contains(@class, 's_ipt_wr')]/input").send_keys("python") #"百度一下“按钮 xpath属性层级 定位 driver.find_element_by_xpath("//span[@class='bg s_btn_wr']/input").click()
