层级定位
1、定位一组对象 find_elements()
举例:
current = os.getcwd()
chrome_driver_path =os.path.join(current,'../webdriver/chromedriver') page_path = os.path.join(current,'../pages/element_samples.html') #本地html文件 driver = webdriver.Chrome(executable_path=chrome_driver_path) driver.get('file://'+page_path) # driver.implicitly_wait(20) elems = driver.find_elements(By.XPATH,'//*/input[@type="radio"]') print(type(elems),len(elems)) i =0 if elems: for el in elems: el.click() print('第%d次勾选'%(i+1)) i+= 1 time.sleep(2) else: print("没有找到该元素") driver.quit()
2、两个find_element层级定位:

driver.find_element(By.XPATH,'//div[@id="radio"]').find_element(By.XPATH,'//input[class="AliBaBa"]').click()
3、多层网页嵌套(页面有a,b两个frame,其中b在a内,要定位b的内容则需要先定位到a,再切到b)
1)switch_to_frame()方法,表示把当前定位主题切换到frame里,其参数必须是id或name
举例:
frame1 = driver.find_element(By.XPATH,'//iframe')
driver.switch_to.frame(frame1)
driver.find_element(By.XPATH,'//*/body/input[@id="input1"]').send_keys('dsd') driver.find_element(By.XPATH,'//*/body/input[2]').send_keys('dsd') # driver.switch_to_frame('frame1') #方法目前还可用,但是已有新方法 time.sleep(3) driver.quit()
2)再跳回到主框架页:driver.switch_to.default_content() #跳转主框架页
