如果你的webdriver中没有 `find_element_by_css_selector` 这个方法,可能是因为你使用的是旧版本的webdriver。建议你升级webdriver到最新版本,或者使用其他的定位方法,例如 `find_element_by_xpath`、`find_element_by_id` 等等。另外,如果你想使用CSS选择器定位元素,你也可以使用 `find_element(By.CSS_SELECTOR, css_selector)` 方法。

WebDriver有无find_element_by_css_selector用法
在Selenium中,WebDriver对象本身没有直接的`find_element_by_css_selector`方法。相反,您应该使用WebDriver对象的`find_element`方法,然后将`By.CSS_SELECTOR`作为定位器参数传递进去。
以下是使用WebDriver对象的`find_element`方法和CSS选择器的示例代码:
```python
from selenium import webdriver
from selenium.webdriver.common.by import By
# 启动浏览器
driver = webdriver.Chrome()
# 打开网页
driver.get("https://www.example.com")
# 使用CSS选择器查找元素
element = driver.find_element(By.CSS_SELECTOR, "h1.title")
# 打印元素文本
print(element.text)
# 关闭浏览器
driver.quit()
```
在上述示例中,我们使用了`driver.find_element`方法,并将`By.CSS_SELECTOR`作为第一个参数传递进去,然后将CSS选择器`"h1.title"`作为第二个参数传递进去。这样就可以使用CSS选择器来定位元素。您可以根据需要修改CSS选择器来匹配您想要查找的元素。
webdriver object has no attribute find_element_by_css_selector
This error occurs when you try to use the method "find_element_by_css_selector" on a webdriver object that does not support this method.
There are a few possible reasons why this error may occur:
1. You may have misspelled the method name. Double-check that you have spelled it correctly: "find_element_by_css_selector".
2. You may be using an outdated version of the webdriver or the Selenium library. Make sure you have the latest version installed.
3. You may be using the wrong type of webdriver. Not all webdrivers support the "find_element_by_css_selector" method. For example, if you are using the "Firefox webdriver", it does not support this method. You should use the "Chrome webdriver" or the "Edge webdriver" instead.
To fix this issue, make sure you are using the correct webdriver and that you have spelled the method name correctly.
