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，并得到以下错误：

Internal Server Error: /identigo

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

下面是我的代码，由于与我的问题无关，所以省略了导致该页面的脚本。

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，用户选择约会日期和时间；我希望脚本等待“开始”按钮被推，然后在下面的截图中点击“继续”：

null

当我单击“View page source”时，弹出的html不会显示在源代码中，所以我假设它是用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webdriverwait(driver,1000000)行更改为webdriverwait(driver,30)，则会出现以下错误：

Internal Server Error: /identigo

到目前为止的项目代码，所以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

...暗示WebDriver实例（即driver）无法在视口内滚动元素以调用click()。

首先，由于您的习惯是在元素上调用click()，因此理想情况下，您需要将ExpectedConditions用作element_to_be_clickable()，而不是使用presence_of_element_locited():

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

null

另外，根据错误消息，要在调用click()之前在视口中滚动元素，还可以使用element.scrollintoView（）方法。

您可以在下面找到详细的讨论：-不同滚动选项之间的区别是什么？

在这一点上值得一提的是，以下方法：

null

DevTools快照：

由于所需的元素位于模态对话框中，因此要在元素上找到并调用click()，您必须为element_to_be_clickable()导入WebDriverWait，您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()

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