问题

我对Selenium还不太熟悉，正在开发一个小测试脚本：

```python
from selenium import webdriver
from selenium.webdriver.firefox.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
from selenium.common.exceptions import NoSuchElementException
from selenium.webdriver.common.action_chains import ActionChains

url = "https://www.imdb.com/title/tt0368226/reviews"

options = Options()
# options.add_argument('-headless')
driver = webdriver.Firefox(options=options)

# 加载IMDb页面
driver.get(url)

while True:
    try:
        button = WebDriverWait(driver, 10).until(
            EC.visibility_of_element_located((By.ID, 'load-more-trigger')))
        actions = ActionChains(driver)
        actions.move_to_element(button).perform()
        button.click()
    except NoSuchElementException:
        break

我希望这个脚本能够不断点击“加载更多”按钮，直到该按钮不再出现在页面上。然而，当我运行这个脚本时，它只点击了一次按钮，然后我收到了这个错误消息：selenium.common.exceptions.MoveTargetOutOfBoundsException: Message: (479, 4602) is out of bounds of viewport width (1280) and height (827)

我查看了许多相关的Stack Overflow问题，但都没有解决我的问题。我觉得问题已经很接近了，可能是我漏看了什么。非常感谢您的帮助！

so i&#39;m pretty new to selenium and have a little test script i&#39;m working on:

from selenium import webdriver
from selenium.webdriver.firefox.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
from selenium.common.exceptions import NoSuchElementException
from selenium.webdriver.common.action_chains import ActionChains

url = "https://www.imdb.com/title/tt0368226/reviews"

options = Options()

options.add_argument('-headless')

driver = webdriver.Firefox(options=options)

Load the IMDb page

driver.get(url)

while True:
try:
button = WebDriverWait(driver, 10).until(
EC.visibility_of_element_located((By.ID, 'load-more-trigger')))
actions = ActionChains(driver)
actions.move_to_element(button).perform()
button.click()
except NoSuchElementException:
break

what i'd like for this script to do is to continuously click on the 'load more' button until it is no longer on the page. however, when i run this script, it presses the button once and then i receive this error: ``` selenium.common.exceptions.MoveTargetOutOfBoundsException: Message: (479, 4602) is out of bounds of viewport width (1280) and height (827) ```

i've checked out numerous SO questions with solutions and none have done the trick so far. i feel like this is very close and i'm just overlooking something. any help would be greatly appreciated. thanks all!

这里不需要使用`ActionChains`来执行对`Load More`按钮的点击。

以下是解决方案：
```python
from selenium import webdriver
from selenium.webdriver.firefox.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
from selenium.common.exceptions import NoSuchElementException, TimeoutException

url = "https://www.imdb.com/title/tt0368226/reviews"

options = Options()
# options.add_argument('-headless')
driver = webdriver.Firefox(options=options)

# 加载 IMDb 页面
driver.get(url)

while True:
    try:
        button = WebDriverWait(driver, 10).until(
            EC.visibility_of_element_located((By.ID, 'load-more-trigger')))

        button.click()
    except (NoSuchElementException, TimeoutException):
        break

这个while循环会不断寻找Load More按钮并点击，直到没有更多的Load More按钮可点击，最终会超时并退出循环。

from selenium import webdriver
from selenium.webdriver.firefox.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
from selenium.common.exceptions import NoSuchElementException, TimeoutException

url = "https://www.imdb.com/title/tt0368226/reviews"

options = Options()
# options.add_argument('-headless')
driver = webdriver.Firefox(options=options)

# Load the IMDb page
driver.get(url)

while True:
    try:
        button = WebDriverWait(driver, 10).until(
            EC.visibility_of_element_located((By.ID, 'load-more-trigger')))

        button.click()
    except (NoSuchElementException, TimeoutException):
        break
