Question

我对硒有一个问题：

我无法单击由我单击的第一个按钮创建的弹出窗口中包含的按钮

    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.webdriver.firefox.options import Options

    # Webdriver
    browser = webdriver.Chrome('C:\\Users\\zlell\\PycharmProjects\\PyroLello\\Userbot\\chromedriver.exe')
    browser.get("https://www.eventbrite.com/e/120621788015")

    # This button originates a pop-up
    python_button = browser.find_element_by_xpath('//*[@id="eventbrite-widget-modal-trigger-120621788015"]')

    # Click
    python_button.click()

    # The pop-up with the new button appears

    # Try to find the button included in the pop-up - Doesn't work
    python_button_2 = browser.find_element_by_css_selector("button.eds-btn.eds-btn--button.eds-btn--fill")

    # Click - Doesn't Work
    python_button_2.click()

错误：

第二个按钮-包括在弹出窗口中：

Answer 1

添加页面加载后的等待。抓住iframe并切换到它

iframe = WebDriverWait(browser, 10).until(EC.presence_of_element_located((By.TAG_NAME, "iframe")))
browser.switch_to.frame(iframe)
python_button_2 =WebDriverWait(browser, 10).until(EC.presence_of_element_located((By.CSS_SELECTOR, "button.eds-btn.eds-btn button.eds-btn fill")))
