我必須找到這個文本并選擇。
我試過 ：
element = driver.find_element_by_xpath('//*[@id="product-detail-app"]/div/div[3]/div[1]/div[2]/div[3]/div[2]/div[3]').text
print(element)
但它給出了錯誤：
---------------------------------------------------------------------------

我嘗試了不同的解決方案，但沒有奏效。這是一個可選擇的div. 我必須找到我需要的文本并將其設定為可選。但是我找不到文本。請幫幫我，謝謝。
uj5u.com熱心網友回復：
嘗試在訪問元素之前添加等待，如下所示：
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
wait = WebDriverWait(driver, 20)
value = wait.until(EC.visibility_of_element_located((By.XPATH, '//*[@id="product-detail-app"]/div/div[3]/div[1]/div[2]/div[3]/div[2]/div[3]'))).text
print(value)
此外，您的 XPath 定位器看起來很糟糕。In 可能非常不可靠。
UPD
該元素的更好的 XPath 定位器可以是//div[@class='variants']//div[text()='38']這樣您的代碼將是：
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
wait = WebDriverWait(driver, 20)
value = wait.until(EC.visibility_of_element_located((By.XPATH, "//div[@class='variants']//div[text()='38']"))).text
print(value)
UPD
看來您必須切換到新視窗。
嘗試這個：
new_window = driver.window_handles[-1]
driver.switch_to_window(new_window)
要回傳第一個視窗，您必須執行以下操作：
old_window = driver.window_handles[0]
driver.switch_to_window(old_window)
