硒没有找到特定的元素

Question

我试图导航到＆＃39;人物＆＃39;执行flickr.com搜索后的部分（https://www.flickr.com/search/?text=lake）。

我无法在<div id="content">中找到元素（HTML图片中从第6行开始）。基本上无论我尝试什么，都会抛出NoSuchElementException。

#! python3

# Saves photos to file from flickr.com using specified search term

    content = driver.find_element_by_id("content")
    content.find_element_by_class_name("search-subnav-content")

if __name__ == "__main__":

Answer 1

我会直接导航到搜索结果页面并等待结果显示：

driver.get("https://www.flickr.com/search/?text=" + search_term)

# wait for the search results to appear
wait = WebDriverWait(driver, 10)
wait.until(EC.visibility_of_element_located((By.CLASS_NAME, "search-photos-results")))

content = driver.find_element_by_id("content")
content.find_element_by_class_name("search-subnav-content")
