Question

我尝试通过滚动到元素来单击隐藏的按钮，但仍然无法正常工作。仅当我手动滚动它时，编码才起作用。我可以知道原因吗？谢谢！网站：https://www1.hkexnews.hk/search/titlesearch.xhtml?lang=en

Answer 1

您可能会滚动到element（button）。如果您的网页具有任何功能区，那么这又将被隐藏。尝试滚动到其上方的任何其他元素。这解决了我的问题。

Answer 2

您必须先滚动到每个菜单项，然后才能使用JavaScript arguments[0].scrollIntoView(true);

您可以使用常规方法进行滚动，然后再单击下面的代码，就像下面的代码一样：

def click(element):
    driver.execute_script("arguments[0].scrollIntoView(true);", element)
    element.click()


driver = webdriver.Chrome()
driver.get("https://www1.hkexnews.hk/search/titlesearch.xhtml?lang=en")

driver.find_element_by_css_selector(".searchType").click()
driver.find_element_by_xpath("//div[@class='droplist-item' and ./a[.='Headline Category']]").click()
driver.find_element_by_id("rbAfter2006").click()

click(driver.find_element_by_xpath("//a[.='Debt and Structured Products']"))
click(driver.find_element_by_xpath("//a[.='Debt Securities']"))
click(driver.find_element_by_xpath("//a[.='Issuer-Specific Report - Debt Securities']"))

或者您可以使用如下所示的菜单选择特定方法：

def select_menu(menu_text):
    element = driver.find_element_by_xpath(f"//a[.='{menu_text}']")
    driver.execute_script("arguments[0].scrollIntoView(true);", element)
    element.click()


driver = webdriver.Chrome()
driver.get("https://www1.hkexnews.hk/search/titlesearch.xhtml?lang=en")

driver.find_element_by_css_selector(".searchType").click()
driver.find_element_by_xpath("//div[@class='droplist-item' and ./a[.='Headline Category']]").click()
driver.find_element_by_id("rbAfter2006").click()

select_menu("Debt and Structured Products")
select_menu("Debt Securities")
select_menu("Issuer-Specific Report - Debt Securities")

选择搜索条件的更通用的方法：

def select_search_criteria(criteria, *menus):
    driver.find_element_by_css_selector(".searchType").click()
    criteria_element = driver.find_element_by_xpath(f"//div[@class='droplist-item' and ./a[.='{criteria}']]")
    data_value = criteria_element.get_attribute("data-value")
    criteria_element.click()

    document_type_element = driver.find_element_by_id(data_value)
    if document_type_element.find_element_by_css_selector("a.combobox-field").get_attribute("aria-expanded") == "false":
        document_type_element.click()

    for menu in menus:
        element = document_type_element.find_element_by_xpath(f".//a[.='{menu}']")
        driver.execute_script("arguments[0].scrollIntoView(true);", element)
        element.click()


driver = webdriver.Chrome()
driver.get("https://www1.hkexnews.hk/search/titlesearch.xhtml?lang=en")

select_search_type("Headline Category", "Debt and Structured Products", "Debt Securities")
select_search_type("Document Type", "Circulars")
