Selenium，webdriver - 找不到 - xpath/css_selector/... python

Question

有人可以上传点击此页面中复选框的代码IN PYTHON ONLY-https://www.google.com/recaptcha/api2/demo

我找不到此代码的 xpath ...

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
from selenium.common.exceptions import TimeoutException

driver1 = webdriver.Firefox()
driver1.get("https://www.google.com/recaptcha/api2/demo")
driver1.find_element_by_xpath(...).click()

如果不清楚，我想点击这个按钮（在圆圈中）

Answer 1

xpath 是//*[@class="recaptcha-checkbox-checkmark"]

复选框在iframe中，首先你需要切换到框架然后你可以找到元素并点击。

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
from selenium.common.exceptions import TimeoutException

driver1 = webdriver.Firefox()
driver1.get("https://www.google.com/recaptcha/api2/demo")
driver1.switch_to.frame(driver.find_element_by_css_selector('iframe'))
driver1.find_element_by_xpath('//*[@class="recaptcha-checkbox-checkmark"]').click()

我试过用java，它可以点击复选框，java代码如下。

driver=new FirefoxDriver();
driver.get("https://www.google.com/recaptcha/api2/demo");
driver.switchTo().frame(0);
new WebDriverWait(driver, 120).until(ExpectedConditions.visibilityOf(driver.findElement(By.className("recaptcha-checkbox-checkmark")))).click();

Answer 2

切换到 iFrame 会吸引很多人，但如果您有从不同域（在本例中为验证码）加载的内容，那么您需要使用

切换到该域

driver.switchTo().frame(<integer of frame or id>);

然后您将能够与您选择的选择器进行交互。
