為什么在seleniumpython腳本中獲取selenium.common.exceptions.NoSuchElementException？

我是 selenium 的新手并撰寫了一個腳本來登錄，當我運行腳本時出現以下錯誤：-

錯誤：-

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":"[id="SignIn Form_email"]"}

腳本：-

url = "https://someurl.com"
driver = webdriver.Chrome(executable_path="C:\CustomDrivers\chromedriver_win32\chromedriver")
driver.get(url)
print(driver.title)
user_id = driver.find_element_by_id("SignIn Form_email")
user_id.send_keys("[email protected]")

user_password = driver.find_element_by_id("SignIn Form_password")
user_password.send_keys("web$$DD")

driver.find_element_by_xpath("//*[@id='SignIn Form']/div[3]/div/div/div/button").click()
print(driver.title)
time.sleep(5)

完整的錯誤跟蹤：-

提前致謝 希望您??能盡快到訪。

HTML 在哪里？沒有它，我們真的幫不了你。

順便說一句，你的user_id和user_password看起來像一個類名，你確定find_element_by_id方法嗎？你不應該用find_element_by_class嗎？

通過看到這個錯誤

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":"[id="SignIn Form_email"]"}

你必須確保

1. 這[id="SignIn Form_email"]不是在iframe.
2. 這[id="SignIn Form_email"]不是下一個shadow-root.
3. 您不應該在 selenium 啟動的新選項卡/視窗上。
4. 您可能正在嘗試與元素互動，但它尚未完全渲染。

另外，請檢查dev tools（谷歌瀏覽器）我們是否有唯一的條目HTML DOM。

您應該檢查的 xpath ：

[id="SignIn Form_email"]

檢查步驟：

Press F12 in Chrome- >去element節- >做一個CTRL F- >再貼上xpath看看，如果你需要的element是越來越強調與1/1匹配的節點。

現在，如果是iframe，請切換到iframe first。

wait = WebDriverWait(driver, 30)
wait.until(EC.frame_to_be_available_and_switch_to_it((By.XPATH, "")))

如果element不是呈現問題，請誘導網路驅動程式等待

wait = WebDriverWait(driver, 30)
wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, "")))

進口：

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