我正在嘗試使用selenium從steam 主頁上消失的下拉列表中找到一個元素。當您在搜索欄中鍵入內(nèi)容時，結(jié)果會下拉，如果您在搜索欄外單擊，則下拉結(jié)果會消失。如果您希望結(jié)果再次出現(xiàn)，則需要再次單擊它。無論如何，我的代碼在搜索欄中輸入了一個輸入，并且在運行時會顯示下拉列表input_elem.send_keys(game)（我使用“terraria”作為輸入），并且每個第一個結(jié)果都有相同的 css 選擇器。我也試圖用 xpath 找到元素，它也不起作用：from selenium import webdrivergame = input('Type the game you want to find here: ')# configure browserbrowser = webdriver.Firefox()browser.get('https://store.steampowered.com/')# input gameinput_elem = browser.find_element_by_css_selector('#store_nav_search_term')input_elem.send_keys(game)# click the first resultfirst_match = browser.find_element_by_css_selector('a.match:nth-child(1)')first_match.click()這是完整的錯誤：Traceback (most recent call last): File "/home/fanjin/Documents/Python Projects/web_projects/steam/game_finder.py", line 14, in <module> first_match = browser.find_element_by_css_selector('a.match:nth-child(1)') File "/home/fanjin/.local/lib/python3.8/site-packages/selenium/webdriver/remote/webdriver.py", line 598, in find_element_by_css_selector return self.find_element(by=By.CSS_SELECTOR, value=css_selector) File "/home/fanjin/.local/lib/python3.8/site-packages/selenium/webdriver/remote/webdriver.py", line 976, in find_element return self.execute(Command.FIND_ELEMENT, { File "/home/fanjin/.local/lib/python3.8/site-packages/selenium/webdriver/remote/webdriver.py", line 321, in execute self.error_handler.check_response(response) File "/home/fanjin/.local/lib/python3.8/site-packages/selenium/webdriver/remote/errorhandler.py", line 242, in check_response raise exception_class(message, screen, stacktrace)selenium.common.exceptions.NoSuchElementException: Message: Unable to locate element: a.match:nth-child(1)

要點擊第一個自動建議，您必須為引入WebDriverWaitelement_to_be_clickable()并且您可以使用以下任一定位器策略：
使用CSS_SELECTOR：
driver.get("https://store.steampowered.com/")
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input#store_nav_search_term"))).send_keys("terraria")
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "div#search_suggestion_contents>a"))).click()
使用XPATH：
driver.get("https://store.steampowered.com/")
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "http://input[@id='store_nav_search_term']"))).send_keys("terraria")
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "http://div[@id='search_suggestion_contents']/a"))).click()
注意：您必須添加以下導入：
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
