Selenium Python无法点击搜索按钮问题求助

我正在编写代码实现搜索栏输入内容并点击搜索按钮的功能：

• 搜索栏输入内容的部分运行正常；
• 但点击搜索按钮的部分始终无法实现，查了大量资料、试了好几个小时，所有方法都没用……

目标网站：https://ec.europa.eu/info/funding-tenders/opportunities/portal/screen/opportunities/topic-search

搜索按钮的HTML结构：

<button type="submit" id="f2q3fi9kd" class="btn ux-button btn-accent btn-lg ux-button--large ux-button--icon-only" tabindex="0" aria-disabled="false" data-e2e="ux-button">

初始代码：
（xxx为需要填写的按钮定位代码）

from selenium import webdriver
from bs4 import BeautifulSoup as soup
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.service import Service as ChromeService 
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver import ActionChains
from selenium.webdriver.common.keys import Keys 

cc_driver = webdriver.Chrome(service=ChromeService(ChromeDriverManager().install())) 
cc_driver.get('https://ec.europa.eu/info/funding-tenders/opportunities/portal/screen/opportunities/topic-search')
action = ActionChains(cc_driver)

searchTextbox = WebDriverWait(cc_driver, 20).until(EC.presence_of_element_located((By.CSS_SELECTOR, "input[placeholder='Type your Keywords...']" )))
action.move_to_element(searchTextbox).click().send_keys("CREA-CROSS-2023-JOURPART-PLURALISM").perform()

save_Button = WebDriverWait(cc_driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, 'xxx')))
action.move_to_element(save_Button).click()

更新后的尝试代码：

from selenium import webdriver
from bs4 import BeautifulSoup as soup
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.service import Service as ChromeService 
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver import ActionChains
from selenium.webdriver.common.keys import Keys 

cc_driver = webdriver.Chrome(service=ChromeService(ChromeDriverManager().install())) 
cc_driver.get('https://ec.europa.eu/info/funding-tenders/opportunities/portal/screen/opportunities/topic-search')
action = ActionChains(cc_driver)

# 输入搜索内容
searchTextbox = WebDriverWait(cc_driver, 20).until(EC.presence_of_element_located((By.CSS_SELECTOR, "input[placeholder='Type your Keywords...']" )))
action.move_to_element(searchTextbox).click().send_keys("CREA-CROSS-2023-JOURPART-PLURALISM").perform()

# 尝试1
save_Button = WebDriverWait(cc_driver, 20).until(EC.element_to_be_clickable((By.CLASS_NAME, 'icon-search.ux-u-font-size-h2')))
cc_driver.execute_script("arguments[0].click();", save_Button)

# 尝试2
save_Button = WebDriverWait(cc_driver, 20).until(EC.element_to_be_clickable((By.CLASS_NAME, 'icon-search.ux-u-font-size-h2')))
action.move_to_element(save_Button).click()
cc_driver.execute_script("arguments[0].click();", save_Button)

# 尝试3
save_Button = WebDriverWait(cc_driver, 20).until(EC.element_to_be_clickable((By.CLASS_NAME, 'icon-search.ux-u-font-size-h2')))
save_Button.click()

# 尝试4
save_Button = WebDriverWait(cc_driver, 20).until(EC.element_to_be_clickable((By.CLASS_NAME, 'icon-search.ux-u-font-size-h2')))
save_Button.click()
cc_driver.execute_script("arguments[0].click();", save_Button)

你的问题核心是元素定位错误，以下是可行的修复方案：

1. 正确定位搜索按钮 #

你之前用By.CLASS_NAME定位icon-search.ux-u-font-size-h2是错误的：

• CLASS_NAME不支持多类名（.分隔的多个类）；
• 这个类属于按钮内部的图标元素，而非按钮本身。

根据提供的HTML，推荐两种可靠定位方式：

• 方案A：用data-e2e属性定位（e2e标识一般不会轻易变动）

save_Button = WebDriverWait(cc_driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, 'button[data-e2e="ux-button"]')))

• 方案B：用按钮的类组合+类型定位

save_Button = WebDriverWait(cc_driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, 'button.btn.ux-button.btn-accent.btn-lg.ux-button--large.ux-button--icon-only[type="submit"]')))

2. 简化交互逻辑 #

搜索场景下，直接给搜索框发送回车键比点击按钮更稳定，可替代按钮点击：

searchTextbox.send_keys(Keys.ENTER)

完整修复代码 #

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.service import Service as ChromeService 
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.common.keys import Keys 

cc_driver = webdriver.Chrome(service=ChromeService(ChromeDriverManager().install())) 
cc_driver.get('https://ec.europa.eu/info/funding-tenders/opportunities/portal/screen/opportunities/topic-search')

# 方式1：输入内容后回车搜索（推荐）
searchTextbox = WebDriverWait(cc_driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input[placeholder='Type your Keywords...']")))
searchTextbox.click()
searchTextbox.send_keys("CREA-CROSS-2023-JOURPART-PLURALISM")
searchTextbox.send_keys(Keys.ENTER)

# 方式2：定位按钮后点击（二选一即可）
# save_Button = WebDriverWait(cc_driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, 'button[data-e2e="ux-button"]')))
# save_Button.click()

额外提示 #

• 优先用EC.element_to_be_clickable代替presence_of_element_located，确保元素可交互；
• 避免重复定位同一元素，浪费资源；
• 若页面有Cookie弹窗等遮挡元素，需先处理弹窗再操作。
