Python selenium error: no such element: able to locate eleme

Question

我一直在试图找出这个错误，直到现在几个小时。

我试着点击屏幕上的红色按钮，但是不知为什么我不能使用xpath方法。

错误信息如下:

Message: no such element: Unable to locate element: {"method":"xpath","selector":"//*[@id="mapContainer"]"}
(Session info: chrome=107.0.5304.107)

我的目标是抓取当按钮被点击时弹出屏幕显示的信息。

我不认为你做错了什么。添加显式等待总是会提高可靠性，因为您不太容易受到时间问题的影响:

iframe = WebDriverWait(dr, 10).until(EC.presence_of_element_located((By.ID, "DivMapOpenLayers")))
driver.switch_to.frame(iframe)
CHOICE = {'경기':2, '강원':3, '충북':4, '충남':5, '전북':6, '전남':7, '경북':8, '경남':9, '제주':10}
CHOICE = CHOICE.get('전남') 
WebDriverWait(dr, 10).until(EC.presence_of_element_located((By.XPATH, f'//*[@id="xcontainer_reservoir"]/table[3]/tbody/tr[{CHOICE}]/td[2]'))).click()
WebDriverWait(dr, 10).until(EC.presence_of_element_located((By.XPATH, f'//*[@id="xcontainer_reservoir"]/table[3]/tbody/tr[2]/td[2]'))).click()
ee = WebDriverWait(dr, 10).until(EC.presence_of_element_located((By.XPATH, '//*[@id="mapContainer"]')))
print(ee.get_attribute("textContent"))
