使用selenium点击链接

Question

我正在尝试使用 selenium 单击链接然后退出。我是编程新手，但我看过一些有关这方面的教程，但仍然无法点击进入页面。我的代码如下，任何帮助将不胜感激！当我只是想从有效的网站上提取建筑物名称时。我似乎无法弄清楚为什么这不会。

driver.get("https://www.usgbc.org/projects/?Country=%5B%22United+States%22%5D&Rating+System=%5B%22New+Construction%22%5D&Rating+Version=%5B%22v2009%22%5D&Certification=%5B%22Platinum%22%5D&State=%5B%22Texas%22%5D")
#check this is the right website
#print(driver.title)

buildings = []

try:
    project_profiles = driver.find_elements(By.CLASS_NAME, "grid-item--title")
    
    for profile in project_profiles:
        
        building_name = profile.text
        buildings.append(building_name)
        print(building_name)

        #load building profile page
        building_profile_link = driver.find_element(By.LINK_TEXT, building_name).click()
        time.sleep(5)
        
        driver.back()
except:
    driver.quit()

我尝试仅使用字符串和变量名称，但都不起作用

Answer 1

有两件事你必须解决 首先是将 Find by Linktext 替换为 PARTIAL_LINK_TEXT

building_profile_link = driver.find_element(By.PARTIAL_LINK_TEXT, building_name)

第二个是，一旦您单击当前页面中的链接，转到下一页并返回，project_profiles 元素列表将变得过时，您将在单击时获得过时的元素引用，因此您应该再次找到该列表以避免这种情况
