class MyGlobals(_AppCtxGlobals):
    user: User

g: MyGlobals

Answer 1

当然，在合适的情况下，我总是更喜欢使用xpath来获取元素。话虽如此，我修改了您的代码以使用xpath找到前进按钮，并且它可以正常工作。

这是修改后的代码：

driver = webdriver.Chrome('chromedriver.exe', chrome_options=options)

driver.get('https://physionet.org/lightwave/?db=noneeg/1.0.0')

def get_spo2hr(subject):
    driver.find_element_by_xpath("//select[@name='record']/option[text()='" + subject + "']").click()
    driver.find_element_by_id('ui-id-3').click()
    driver.find_element_by_id('viewann').click()
    driver.find_element_by_id('viewsig').click()
    driver.find_element_by_id('lwform').click()
    driver.find_element_by_xpath('/html/body/div[1]/main/div/div/div/form/div[3]/table/tbody/tr/td[2]/div/button[3]').click()
    driver.save_screenshot('screenie.png')


get_spo2hr('Subject10_SpO2HR')

一件事是（如其他答案所述）不稳定的CSS选择器更喜欢xpath

但是最主要的是div在dom渲染时与a项重叠只需等待一秒钟，直到dom加载：

import time
time.sleep(1)

示例代码：

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions

driver = webdriver.Chrome()
driver.get('https://physionet.org/lightwave/?db=noneeg/1.0.0')

def get_spo2hr(subject):
    driver.find_element_by_xpath("//select[@name='record']/option[text()='"+subject+"']").click()

    import time
    time.sleep(1)

    driver.find_element_by_id('ui-id-3').click()
    driver.find_element_by_id('viewann').click()
    driver.find_element_by_id('viewsig').click()
    driver.find_element_by_id('lwform').click()
    driver.find_element_by_xpath('/html/body/div[1]/main/div/div/div/form/div[3]/table/tbody/tr/td[2]/div/button[3]').click()
    driver.save_screenshot('screenie.png')

get_spo2hr('Subject10_SpO2HR')

Python硒按类单击按钮不起作用
