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 message usually indicates that you are trying to use the `find_element_by_css_selector` method on the wrong object.
Most likely, you are trying to use `find_element_by_css_selector` on a `webdriver` object, which does not have this method. Instead, you should use it on a `WebElement` object.
For example, if you want to find an element by its CSS selector, you can first use the `find_element` method to locate the element, and then use the `find_element_by_css_selector` method on the resulting `WebElement` object:
```
# Find the parent element
parent_element = driver.find_element(By.XPATH, '//div[@class="parent"]')
# Find the child element by CSS selector
child_element = parent_element.find_element_by_css_selector('.child')
```
Alternatively, you can use the `find_elements_by_css_selector` method on a `webdriver` object to find multiple elements that match the CSS selector:
```
# Find all elements with class "my-class"
elements = driver.find_elements_by_css_selector('.my-class')
```
