Python Selenium爬Glassdoor评论：搜索选列表第一项报错解决

错误原因 #

你代码中触发错误的核心问题在于这行代码：

Company=driver.find_element(By.ID,"sc\.keyword").send_keys("Amazon")

send_keys()方法执行后返回的是None，因此Company变量被赋值为None，后续调用Company.send_keys(Keys.ENTER)时，自然会抛出AttributeError: 'NoneType' object has no attribute 'send_keys'。

另外，你写的ID选择器"sc\.keyword"存在冗余转义，Glassdoor搜索框的实际ID是sc.keyword，不需要加反斜杠，这也可能导致元素定位失败，进一步加剧问题。

修复方案 #

1. 拆分元素定位与操作
   先单独定位搜索框元素，再分别执行输入和回车操作：

# 正确定位搜索框，去掉不必要的反斜杠
search_box = driver.find_element(By.ID, "sc.keyword")
# 输入公司名称
search_box.send_keys("Amazon")
# 发送回车触发搜索
search_box.send_keys(Keys.ENTER)

2. 优化元素定位稳定性
   尽量用WebDriverWait替代time.sleep，确保元素加载完成后再操作，同时修正导航栏元素的定位语法（By.CLASS_NAME不支持CSS伪类，改用By.CSS_SELECTOR）：

# 等待导航栏第二个元素可点击后点击
WebDriverWait(driver, 15).until(
    EC.element_to_be_clickable((By.CSS_SELECTOR, ".siteHeader__HeaderStyles__navigationItem:nth-child(2)"))
).click()

# 等待搜索框加载完成
search_box = WebDriverWait(driver, 15).until(
    EC.element_to_be_clickable((By.ID, "sc.keyword"))
)
search_box.send_keys("Amazon")
search_box.send_keys(Keys.ENTER)

3. 清理冗余代码
   你重复初始化了两次Chrome Driver，删掉其中一次，避免资源浪费：

# 删掉重复的这一行
# driver = webdriver.Chrome(driver_path, chrome_options=options)
