我對編碼比較陌生，對堆疊跟蹤錯誤有點不熟悉。我收到了這個錯誤，但我不確定我要修復代碼的哪一部分？錯誤是由于 NoSuchElementException 引起的，還是由于超時錯誤？
我認為在我的代碼中我已經處理了程式將如何面對 nosuchelement 例外。基本上，我的代碼搜索可用的插槽，并在插槽可用時禁用后退按鈕。但是，當網頁空閑時間過長時，我遇到了其他型別的錯誤，例如連接超時。因此，我現在的任務是過濾掉我面臨的不同問題，以便我可以分別處理這些問題。我添加了預期條件作為過濾器來區分我面臨的錯誤
代碼：
no_slot = True
while no_slot == 1:
for i in range(60):
search_button = browser.find_element(By.NAME, "btnSearch")
search_button.click()
try:
noslot_back_button = browser.find_element(By.CSS_SELECTOR, 'input[name="btnBack"]')
except NoSuchElementException:
if EC.presence_of_element_located(browser.find_element(By.XPATH, '//td[@]')):
# Proceed with booking (make sure that it is at the booking page (implementation)
slot_radio_info = browser.find_element(By.NAME, 'slot')
slot_id = slot_radio_info.get_attribute('id')
radio_button = browser.find_element(By.XPATH, '//input[@id="' str(slot_id) '"]')
radio_button.click()
slot_submit_button = browser.find_element(By.CSS_SELECTOR, 'input[value="Submit"]')
WebDriverWait(EC.element_to_be_clickable(slot_submit_button))
slot_submit_button.click()
double_cfm_button = browser.find_element(By.CSS_SELECTOR, 'input[value="Confirm"]')
double_cfm_button.click()
elif not EC.title_contains('BBDC: Booking For TP Driving Simulator Lesson'):
print("Connection timed out or something else happened")
else:
print("unaccounted condition")

...暗示在定位元素時引發了NoSuchElementException。
解決NoSuchElementException
如果定位器策略在HTML DOM 中唯一標識元素，則沒有元素的相關 HTML 將難以解決。
此外，雖然您正在使用，chrome=95.0.4638.69但您的ChromeDriver版本與 Chrome 瀏覽器版本不同步。因此，您會看到Backtrace。
解決方案
確保這件事：
- ChromeDriver更新到當前ChromeDriver v95.0級別。

Selenium 無法定位元素，
noslot_back_button = browser.find_element(By.CSS_SELECTOR, 'input[name="btnBack"]')
很可能是打字錯誤，或者您可能忘記命名 css 選擇器。
