Selenium python 错误:元素无法滚动到视图中 [英] Selenium python Error: element could not be scrolled into view
问题描述
我正在为我的公司自动化 IdentiGO 应用程序，但出现以下错误:

Here is my code, with the scripts leading up to this page omitted since they aren't relevant to my problem.
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:
If you would like to see the exact page, go to this url, then you will have to make a series of POST requests using the following info:
- click schedule a new appointment
- other
- vendors and contractors (children)
- tnvc00047
- 37204
- make random appointment date
Any advice would really be appreciated!
Update
Here is a JS Fiddle with the html of the page:
https://jsfiddle.net/khf4tym3/
When I click "view page source", the popup html doesn't show in the source code, so I assume that it is generated with JS.
<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>
Update 2
If I change the line WebDriverWait(driver, 1000000) to WebDriverWait(driver, 30), I get the following error instead:
Internal Server Error: /identigo

code for the project so far, so you can skip the forum entry.

The working solution:
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()
This error message...
selenium.common.exceptions.ElementNotInteractableException: Message: Element <span class="ui-button-text"> could not be scrolled into view
...implies that the WebDriver instance i.e. driver was unable to scroll the element within the Viewport to invoke click().
First of all, as your usecase is to invoke click() on the element, ideally instead of using presence_of_element_located() you need to use the ExpectedConditions as element_to_be_clickable() as follows:
WebDriverWait(driver, 1000000).until(EC.element_to_be_clickable((By.XPATH, '/html/body/div[5]/div[3]/div/button/span'))).click()
You can find a couple of detailed discussions in:
- 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
As an alternative, as per the error message, to scroll an element within the Viewport before invoking click() you can also use the Element.scrollIntoView() method.
You can find a detailed discussion in: - What is the difference between the different scroll options?
At this point it is worth to mention, the following methods:
- move_to_element() from selenium.webdriver.common.action_chains
- element_to_be_clickable() from selenium.webdriver.support.expected_conditions
will automatically scroll the element within the Viewport.

This usecase
The button with text as Continue is within the Top Level Content but rendered within a Modal Dialog Box.
DevTools Snapshot:
As the desired element is within a Modal Dialog Box, so to locate and invoke click() on the element you have to induce WebDriverWait for the element_to_be_clickable() and you can use the following Locator Strategy:
Using
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()Note : You have to add the following imports :
from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.common.by import By from selenium.webdriver.support import expected_conditions as EC
