[英]Python selenium click button by class not working
我正在嘗試單擊帶有 class 的按鈕,但它會引發 ElementNotInteractableException。 這是網站 HTML 代碼
這是我正在使用的代碼
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_css_selector(".fwd").click()
driver.save_screenshot('screenie.png')
get_spo2hr('Subject10_SpO2HR')
當然,在合適的情況下,我總是更喜歡使用他們的 xpath 獲取元素。 話雖如此,我修改了您的代碼以使用其 xpath 找到前進按鈕並且它可以工作。
這是修改后的代碼:
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)不穩定的 css 選擇器更喜歡 xpath
但最主要的是 div 在 dom 渲染時重疊了 a 項只需等待一秒鍾即可等到 dom 加載:
import time
time.sleep(1)
示例代碼:
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')
