沒有 iframe我收到此錯誤Unable to locate element

我嘗試使用此命令

driver.find_element_by_xpath('//*[@id="root"]/div/div[2]/header/div/button/div/div/svg').click()

Answer 1

您的 xpath 不正確。 使用.dropButton button css 選擇器和WebDriverWait等待元素可點擊。 您可以在此處找到有關定位器策略的有用信息。

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

wait = WebDriverWait(driver, 15)
wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, '.dropButton button'))).click()

如果有更多帶有選擇器的按鈕，請添加具有root ID 的元素：

wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, '#root .dropButton button'))).click()
