python - Selenium python 错误: element could not be scrolled into view

Question

我正在为我的公司自动化 IdentiGO 应用程序，但我收到以下错误:

Internal Server Error: /identigo
Traceback (most recent call last):

    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.ElementNotInteractableException: Message: Element <span class="ui-button-text"> could not be scrolled into view

这是我的代码，省略了通往此页面的脚本，因为它们与我的问题无关。

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC


WebDriverWait(driver, 1000000).until(EC.presence_of_element_located((By.XPATH, '/html/body/div[5]/div[3]/div/button/span'))).click()

On the page prior to this code, where the user selects an appointment date and time; I want the script to wait for the "Go" button to be pushed, then click on "Continue" in the following screenshot:

如果您想查看确切的页面，请转到 this url，那么您将必须使用以下信息发出一系列 POST 请求:

• 点击安排新约会
• 其他
• 供应商和承包商( child )
• tnvc00047
• 37204
• 随机安排约会

如有任何建议，我们将不胜感激!

更新

这是带有页面 html 的 JS Fiddle:

https://jsfiddle.net/khf4tym3/

当我点击“查看页面源代码”时，源代码中没有显示弹出的html，所以我认为它是用JS生成的。

<div class="ui-dialog-buttonset">
    <button type="button" class="ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only" role="button" aria-disabled="false">
        <span class="ui-button-text">Continue</span>
    </button>
</div>

更新2

如果我将行 WebDriverWait(driver, 1000000) 更改为 WebDriverWait(driver, 30)，则会收到以下错误:

到目前为止的项目代码，因此您可以跳过论坛条目。

工作解决方案:

WebDriverWait(driver, 20).until(expected_conditions.element_to_be_clickable((By.XPATH, "//div[starts-with(@aria-describedby, 'ui-id-')]//span[@class='ui-button-text' and text()='Continue']"))).click()

这个错误信息...

selenium.common.exceptions.ElementNotInteractableException: Message: Element <span class="ui-button-text"> could not be scrolled into view

...暗示 WebDriver 实例，即 driver 无法滚动 Viewport 中的元素调用 click()。

---

首先，由于您的用例是在元素上调用 click()，理想情况下您需要使用 ExpectedConditions 而不是使用 presence_of_element_located() 作为 element_to_be_clickable() 如下:

WebDriverWait(driver, 1000000).until(EC.element_to_be_clickable((By.XPATH, '/html/body/div[5]/div[3]/div/button/span'))).click()

您可以在以下位置找到一些详细的讨论:

• Message: Element could not be scrolled into view while trying to click on an option within a dropdown menu through Selenium
• org.openqa.selenium.ElementNotInteractableException: Element could not be scrolled into view when trying to click a button

---

作为替代方案，根据错误消息，要在调用 click() 之前滚动 Viewport 中的元素，您还可以使用 Element.scrollIntoView()方法。

---

此时值得一提的是，以下方法:

• move_to_element()来自 selenium.webdriver.common.action_chains
• element_to_be_clickable()来自 selenium.webdriver.support.expected_conditions

将自动滚动 Viewport 中的元素。

这个用例

文本为继续的按钮位于顶级内容中，但在模态对话框中呈现。

开发者工具快照:

由于所需的元素位于模态对话框中，因此要在该元素上定位并调用click()，您必须引入WebDriverWait 对于 element_to_be_clickable()，您可以使用以下 Locator Strategy :

• 使用 XPATH:

  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//div[starts-with(@aria-describedby, 'ui-id-')]//span[@class='ui-button-text' and text()='Continue']"))).click()
  

• 注意:您必须添加以下导入:

  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC
