无法选择元素

Question

我正在尝试用selenium选择一个元素，但我无法选择它。我尝试用xpath，css和执行javascript来选择它来点击它但没有运气。有什么想法吗？

我能够使用katalon ide自动化插件和javascript控制台选择它，这让我相信有一种方法可以做到这一点。

以下是代码：

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

driver = webdriver.Firefox()
driver.get(url="https://www.google.com/recaptcha/api2/demo")
driver.switch_to.frame(0)
driver.find_element(By.CSS_SELECTOR, "div.recaptcha-checkbox-checkmark").click()
driver.switch_to.default_content()
driver.switch_to.frame(1)
WebDriverWait(driver, 30).until(EC.presence_of_element_located((By.CSS_SELECTOR, "a.rc-audiochallenge-tdownload-link")))
driver.find_element(By.CSS_SELECTOR, "a.rc-audiochallenge-tdownload-link").click()

我正在尝试选择音频按钮：

非常感谢任何帮助。

Answer 1

There is no such element locator with a.rc-audiochallenge-tdownload-link, There is id recaptcha-audio-button present on audio button... Try Id selector..e.g.

WebDriverWait(driver, 30).until(EC.presence_of_element_located(By.ID, "recaptcha-audio-button"))
driver.find_element(By.CSS_SELECTOR, "recaptcha-audio-button").click()

Answer 2

我不知道你是怎么写下这样的定位器的：a.rc-audiochallenge-tdownload-link，整个页面中没有这样的元素。网页后来改变了吗？

Answer 3

要点击#recaptcha-audio-button，可以使用（已测试）：

from selenium import webdriver
from selenium.webdriver.common.by import By

driver = webdriver.Firefox()
driver.get(url="https://www.google.com/recaptcha/api2/demo")
driver.switch_to.frame(0)
driver.find_element(By.CSS_SELECTOR, "div.recaptcha-checkbox-checkmark").click()
driver.switch_to.default_content()
driver.switch_to.frame(driver.find_element(By.XPATH, "//iframe[@title='recaptcha challenge']"))
driver.find_element(By.ID, "recaptcha-audio-button").click()
