Question

我目前正在使用一个脚本来自动完成游戏little alchemy 2。

随着游戏的进行，已经发现的物品的库会增加，最终您必须滚动才能找到一些较低的物品。当我尝试抓住的项目不在屏幕上时，Selenium会引发异常MoveTargetOutOfBoundsException。

我试图通过捕获异常来解决此问题，然后使用move_to_element使该物品到达Selenium的范围。但是当我尝试时，什么也没发生。有任何想法吗？

try:
            ActionChains(driver).drag_and_drop(elempic2, workspace).perform()
        except MoveTargetOutOfBoundsException:
            print ("Need to Scroll because if element 2")
            ActionChains(driver).move_to_element(elempic2).perform()
            ActionChains(driver).drag_and_drop(elempic2, workspace).perform()
        print ("Element 2 dragged: " + str(elemname2.text))

引发的错误：

Traceback (most recent call last):
  File "littlealch.py", line 60, in findelements
    ActionChains(driver).drag_and_drop(elempic2, workspace).perform()
  File "/home/joco/.local/lib/python3.6/site-packages/selenium/webdriver/common/action_chains.py", line 80, in perform
    self.w3c_actions.perform()

  File "/home/joco/.local/lib/python3.6/site-packages/selenium/webdriver/remote/errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.MoveTargetOutOfBoundsException: Message: (1624, 957.5) is out of bounds of viewport width (1920) and height (942)

如果您想自己尝试一下，here是仓库。

谢谢您的帮助：）

我会将滚动逻辑转换为不需要显示目标元素的东西，例如沿着这些方向的东西：

y_position = 0
searching = True

while searching:
  try:
    ActionChains(driver).drag_and_drop(elempic2, workspace).perform()
    searching = False
  except MoveTargetOutOfBoundsException:
    y_position += 500
    driver.execute_script('window.scrollTo(0, ' + str(y_position) + ');')
  print ('Element 2 dragged: ' + str(elemname2.text))

这只是使用JavaScript向下滚动页面，直到可以执行工作为止。

Selenium Python：move_to_element不动
