Selenium python错误：元素无法滚动到视图中

Question

我正在为我的公司自动化IdentiGO应用程序，并且出现以下错误：

Internal Server Error: /identigo

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

这是我的代码，省略了导致该页面的脚本，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()

在此代码之前的页面上，用户在其中选择约会日期和时间；我希望脚本等待“ Go”按钮被按下，然后在以下屏幕截图中单击“ Continue”：

如果您想查看确切的页面，请转至该 URL，然后必须使用以下信息进行一系列POST请求：

• 点击安排新约会
• 其他
• 供应商和承包商（儿童）
• tnvc00047
• 37204
• 随机约会

任何建议，将不胜感激！

更新资料

这是带有页面html的JS小提琴：

https://jsfiddle.net/khf4tym3/

当我单击“查看页面源代码”时，弹出HTML不会显示在源代码中，因此我认为它是用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>

如果将行更改WebDriverWait(driver, 1000000)为WebDriverWait(driver, 30)，则会出现以下错误：

到目前为止该项目的代码，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()

此错误消息...

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

...表示WebDriver实例，即驱动程序无法滚动Viewport中的元素以调用click()。

首先，作为你的用例是调用click()的元素，而不是理想的使用presence_of_element_located()，你需要使用ExpectedConditions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：

• 消息：尝试通过Selenium单击下拉菜单中的选项时，元素无法滚动到视图中
• org.openqa.selenium.ElementNotInteractableException：尝试单击按钮时无法将元素滚动到视图中

或者，根据错误消息，在调用之前在视口中滚动元素，click()也可以使用Element.scrollIntoView（）方法。

您可以在以下位置找到详细的讨论：- 不同的滚动选项之间有什么区别？

此时值得一提的是，以下方法：

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

将自动在视口内滚动元素。

您可以在以下位置找到详细的讨论：- 如何在Python中使用Selenium Webdriver滚动网页而不使用javascript方法execute_script（）

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。

DevTools快照：

由于所需元素位于“ 模态对话框”中，因此要click()在该元素上定位和调用，必须为引入WebDriverWait，element_to_be_clickable()然后可以使用以下“ 定位器策略”：

• 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
  

DevTools快照：

Answer 2

使用以下xpath并单击它。

element=WebDriverWait(driver,30).until(EC.element_to_be_clickable((By.XPATH,"//div[@class='ui-dialog-buttonset']/button[@class='ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only']/span[contains(.,'Continue')]")))
element.click()

如果以上单击不起作用，请尝试以下一项。

element=WebDriverWait(driver,30).until(EC.element_to_be_clickable((By.XPATH,"//div[@class='ui-dialog-buttonset']/button[@class='ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only']/span[contains(.,'Continue')]")))
element.location_once_scrolled_into_view
element.click()

或者您可以使用javascripts执行程序单击。

element=WebDriverWait(driver,30).until(EC.element_to_be_clickable((By.XPATH,"//div[@class='ui-dialog-buttonset']/button[@class='ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only']/span[contains(.,'Continue')]")))
driver.execute_script("arguments[0].click();", element)

EDITED

尝试下面的代码，它是单击继续按钮，那里既有继续按钮又有取消按钮。一旦您单击继续，您将另一个另一个继续按钮单击。我已从调度应用程序更新了代码。

#Schedule appointment
ele1=WebDriverWait(driver,40).until(expected_conditions.element_to_be_clickable((By.XPATH,'(//button[@class="jquiButton ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only"]/span[contains(.,"Schedule")])[1]')))
driver.execute_script("arguments[0].click();",ele1)
#click on continue button
WebDriverWait(driver,40).until(expected_conditions.element_to_be_clickable((By.XPATH,'//button[@class="twoButton continueButton ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only"]/span[contains(.,"Continue")]'))).click()
#click on second continue button
WebDriverWait(driver,40).until(expected_conditions.element_to_be_clickable((By.XPATH,'//button[@class="ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only"]/span[contains(.,"Continue")]'))).click()
