使用 Selenium 下载数据，但输入的教科书有默认列表可供选择 (Python)

Question

我正在尝试通过在文本框中输入股票代码并按搜索来打开一个页面。但是输入的股票代码会自动生成一个列表，其中包含其他可供选择的东西。怎样才能选出这样的列表中唯一的第一次？

从硒导入 webdriver

from selenium.webdriver.support.ui import Select
from selenium.webdriver.common.by import By

url = 'https://www1.hkexnews.hk/search/titlesearch.xhtml'
browser = webdriver.Firefox(executable_path = 'C:\Program Files\Mozilla Firefox\geckodriver.exe')
StockList = ['02192']
browser.get(url)
txtBox = browser.find_element_by_id('searchStockCode')
txtBox.send_keys(StockList[0])
txtBox.submit()

Answer 1

您可以使用下方 xpath 点击正在填充的第一个选项。

//div[@class='slimScrollDiv']/descendant::tbody/tr[1]

然后像这样点击它：

wait = WebDriverWait(driver, 20)
wait.until(EC.element_to_be_clickable((By.XPATH, "//div[@class='slimScrollDiv']/descendant::tbody/tr[1]"))).click()

进口：

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

如果您正在寻找完整的工作代码：

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.action_chains import ActionChains

driver = webdriver.Firefox(executable_path = "C:\Program Files\Mozilla Firefox\geckodriver.exe")
driver.maximize_window()
driver.implicitly_wait(30)
driver.get("https://www1.hkexnews.hk/search/titlesearch.xhtml")
wait = WebDriverWait(driver, 20)
StockList = ['02192']
wait.until(EC.element_to_be_clickable((By.ID, "searchStockCode"))).send_keys(StockList[0])
ele = wait.until(EC.element_to_be_clickable((By.XPATH, "//div[@class='slimScrollDiv']/descendant::tbody/tr[1]")))
ActionChains(driver).move_to_element(ele).click().perform()
wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, "a[class*='applyFilters']"))).click()
