问题

我在使用Selenium尝试点击按钮时遇到了这个问题。按钮的HTML如下所示：

<button class="Component-button-0-2-65 Component-button-d1-0-2-68">and 5 more</button>

我的代码如下：

button = EC.element_to_be_clickable((By.XPATH, './/button[contains(@class,"Component-button-d")]'))
if button:
    print("TRUE")
    button.click()

我的输出是：

TRUE
Traceback (most recent call last):
  File "", line 47, in 
    button.click()
AttributeError: 'function' object has no attribute 'click'

我困惑的是，Selenium找到了button元素（执行print(True)语句），但然后click()方法返回了属性错误。

我正在从此页面提取数据：https://religiondatabase.org/browse/regions
我能够提取页面上需要的所有信息，因此导致点击操作的代码是有效的。

我原本期望该元素是可点击的。我不确定如何排除属性错误（函数对象没有click属性）。因为如果我将XPath粘贴到网页上，它会突出显示正确的元素。

<button class="Component-button-0-2-65 Component-button-d1-0-2-68">and 5 more</button>

button = EC.element_to_be_clickable((By.XPATH,'.//button[contains(@class,"Component-button-d")]'))
    if button:
        print("TRUE")
        button.click()

TRUE
Traceback (most recent call last):
  File "", line 47, in <module>
    button.click()
AttributeError: 'function' object has no attribute 'click'

以下是翻译好的部分：

1. "The element search is always done through the driver object which is the WebDriver instance in its core form:" 翻译为："元素搜索始终通过 driver 对象进行，它是 WebDriver 的核心实例："

2. "driver.find_element(By.XPATH, "element_xpath")" 翻译为："driver.find_element(By.XPATH, "element_xpath")"

3. "But when you apply WebDriverWait, the wait configurations are applied on the driver object." 翻译为："但是，当您使用 WebDriverWait 时，等待配置将应用于 driver 对象上。"

4. "WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "element_xpath")))" 翻译为："WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "element_xpath")))"

5. "So even during WebDriverWait the driver object needs to be present along with the expected_conditions and the locator strategy." 翻译为："因此，即使在 WebDriverWait 过程中，driver 对象也需要与 expected_conditions 和 locator strategy 一起存在。"

6. "This usecase" 翻译为："这个用例"

7. "button = EC.element_to_be_clickable((By.XPATH,'.//button[contains(@class,"Component-button-d")]'))" 翻译为："button = EC.element_to_be_clickable((By.XPATH,'.//button[contains(@class,"Component-button-d")]'))"

8. "button object references to a junk value but on probing returns true and prints TRUE but the click can't be performed as button is not of WebElement type." 翻译为："button 对象引用了一个垃圾值，但在探测时返回 true 并打印 TRUE，但无法执行点击操作，因为 button 不是 WebElement 类型。"

9. "Solution" 翻译为："解决方案"

10. "Given the HTML:" 翻译为："给定的HTML："

11. "<button class="Component-button-0-2-65 Component-button-d1-0-2-68">and 5 more</button>" 翻译为："<button class="Component-button-0-2-65 Component-button-d1-0-2-68">and 5 more</button>"

12. "To click on the element you need to induce WebDriverWait for the element_to_be_clickable() and you can use either of the following locator strategies:" 翻译为："要点击元素，您需要使用 WebDriverWait 来诱导 element_to_be_clickable()，并可以使用以下任何一种 locator strategies："

13. "Using XPATH with classname:" 翻译为："使用 XPATH 和 classname："

14. "WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "//button[contains(@class,'Component-button-d')]"))).click()" 翻译为："WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "//button[contains(@class,'Component-button-d')]"))).click()"

15. "Using XPATH with classname and innerText:" 翻译为："使用 XPATH 、 classname 和 innerText："

16. "WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//button[contains(@class,'Component-button-d') and text()='and 5 more']"))).click()" 翻译为："WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//button[contains(@class,'Component-button-d') and text()='and 5 more']"))).click()"

17. "Note: You have to add the following imports :" 翻译为："注意：您必须添加以下导入："

driver.find_element(By.XPATH, "element_xpath")

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "element_xpath")))	

button = EC.element_to_be_clickable((By.XPATH,'.//button[contains(@class,"Component-button-d")]'))

<button class="Component-button-0-2-65 Component-button-d1-0-2-68">and 5 more</button>

你的代码有错误。以下是如何使用预期条件（以及WebDriverWait）的示例：

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
## [...定义你的驱动程序等等]

wait = WebDriverWait(driver, 25)

## [打开一个URL等等]
element = wait.until(EC.presence_of_element_located((By.XPATH, '//div[@class="input-group"]')))
element.click()

Selenium文档可以在这里找到。

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
## [...define your driver here, other imports etc]

wait = WebDriverWait(driver, 25)

##[open a url, etc]
element = wait.until(EC.presence_of_element_located((By.XPATH, '//div[@class="input-group"]')))
element.click()
