如何用Python+Selenium获取元素的aria-disabled属性值？

我有一段基于Selenium的代码，能完成Instagram访问、账号登录、用户搜索操作，但始终无法实现查看类名为_aarf的div元素的aria-disabled属性是否为"true"并打印判断结果的需求。目标元素的HTML结构如下：

<div class="_aarf" aria-disabled="true" role="button" tabindex="-1">

现有实现代码如下：

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.webdriver.support.wait import WebDriverWait

# 指定chromedriver路径
driver = webdriver.Chrome('C:/Users/me/Desktop/IG_APP/chromedriver.exe')

# 打开Instagram
driver.get("http://www.instagram.com")

# 定位用户名输入框
username = WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input[name='username']")))
password = WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input[name='password']")))

# 输入账号密码
username.clear()
username.send_keys("MYUSERID")
password.clear()
password.send_keys("MYPASSWORD")

# 点击登录按钮
button = WebDriverWait(driver, 2).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "button[type='submit']"))).click()

# 处理弹窗
not_now = WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, '//button[contains(text(), "Not Now")]'))).click()
not_now2 = WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, '//button[contains(text(), "Not Now")]'))).click()

import time

# 定位搜索框
searchbox = WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "//input[@placeholder='Search']")))
searchbox.clear()

# 搜索目标用户
keyword = "@test"
searchbox.send_keys(keyword)

time.sleep(2)
searchbox.send_keys(Keys.ENTER)
time.sleep(2)
searchbox.send_keys(Keys.ENTER)
time.sleep(2)

要实现需求，核心是等待目标元素加载完成后，获取其aria-disabled属性值并进行判断。Instagram页面是动态渲染的，建议用WebDriverWait替代time.sleep来等待元素，确保元素已存在于DOM中。

修改后的完整代码如下：

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.webdriver.support.wait import WebDriverWait

# 指定chromedriver路径
driver = webdriver.Chrome('C:/Users/me/Desktop/IG_APP/chromedriver.exe')

# 打开Instagram
driver.get("http://www.instagram.com")

# 定位用户名输入框
username = WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input[name='username']")))
password = WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input[name='password']")))

# 输入账号密码
username.clear()
username.send_keys("MYUSERID")
password.clear()
password.send_keys("MYPASSWORD")

# 点击登录按钮
button = WebDriverWait(driver, 2).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "button[type='submit']"))).click()

# 处理弹窗
not_now = WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, '//button[contains(text(), "Not Now")]'))).click()
not_now2 = WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, '//button[contains(text(), "Not Now")]'))).click()

# 定位搜索框
searchbox = WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "//input[@placeholder='Search']")))
searchbox.clear()

# 搜索目标用户
keyword = "@test"
searchbox.send_keys(keyword)

searchbox.send_keys(Keys.ENTER)
searchbox.send_keys(Keys.ENTER)

# 等待目标元素加载完成，获取aria-disabled属性
target_element = WebDriverWait(driver, 10).until(
    EC.presence_of_element_located((By.CLASS_NAME, "_aarf"))
)
aria_disabled_value = target_element.get_attribute("aria-disabled")

# 判断并打印结果
is_disabled = aria_disabled_value == "true"
print(f"元素是否被禁用（aria-disabled=true）：{is_disabled}")

# 可选：关闭浏览器
# driver.quit()

关键修改说明 #

• 替换了部分time.sleep为WebDriverWait，确保页面元素加载完成后再执行操作
• 使用EC.presence_of_element_located等待目标元素出现在DOM中（如果需要元素可点击，可改用EC.element_to_be_clickable）
• 通过get_attribute("aria-disabled")获取属性值，注意属性值是字符串类型，需与"true"（小写）做比较
• 直接打印判断结果，清晰展示元素是否处于禁用状态
