python - Selenium：选择带有子类别的多个下拉菜单

问题描述

尝试执行以下操作：

  1. 在“股票代码/股票名称”下输入股票代码，等到所有东西弹出并选择第一项
  2. 在标题类别和文件类型下，选择“标题类别”->“公告及通告”->“新上市（上市发行人/新申请人”）->“配发结果”
  3. 点击“搜索按钮”打开新页面
  4. 点击“公告及通告 - [配发结果]”下的链接

解决方案

有 3 到 4 个下拉菜单，在其中一个下拉菜单中我们必须向下滚动，我在 chrome 上尝试了以下代码，似乎工作正常。

示例代码：

driver = webdriver.Chrome(driver_path)
driver.maximize_window()
driver.implicitly_wait(30)
driver.get("https://www1.hkexnews.hk/search/titlesearch.xhtml")
wait = WebDriverWait(driver, 20)
wait.until(EC.element_to_be_clickable((By.ID, "searchStockCode"))).send_keys("01156")
wait.until(EC.element_to_be_clickable((By.XPATH, "//div[@class='slimScrollDiv']/descendant::tbody/tr[1]"))).click()

#first drop down
wait.until(EC.element_to_be_clickable((By.LINK_TEXT, "ALL"))).click()
wait.until(EC.element_to_be_clickable((By.LINK_TEXT, "Headline Category"))).click()

#Second,3rd, 4th drop down
wait.until(EC.element_to_be_clickable((By.LINK_TEXT, "ALL"))).click()
wait.until(EC.element_to_be_clickable((By.LINK_TEXT, "Announcements and Notices"))).click()
ele = wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, "div.droplist-group.droplist-submenu.level2")))
driver.execute_script("arguments[0].scrollTop = arguments[0].scrollHeight", ele)
i = 1
for item in driver.find_elements(By.XPATH, "//li[@class='droplist-item droplist-item-level-2']"):
    ActionChains(driver).move_to_element(driver.find_element_by_xpath(f"(//li[@class='droplist-item droplist-item-level-2'])[{i}]")).perform()
    i = i + 1
    if item.text == "New Listings (Listed Issuers/New Applicants)":
      item.click()
      break

wait.until(EC.element_to_be_clickable((By.LINK_TEXT, "Allotment Results"))).click()

#Search
wait.until(EC.element_to_be_clickable((By.LINK_TEXT, "SEARCH"))).click()
