Python Selenium 每次刷新页面时ID标签都会改变

Question

I am currently trying to automate a data entry process. Every time I refresh the page the ID tags change and make it impossible. I read that I can use CSS selectors or a possible xpath using tags that don't change. It seems that only the ID tags are the problem.

Below is the HTML code for the button. Every time i try and use the CSS selector i got a no such element exception. I think I am doing it wrong. Please help.

<button type="button" class="dark button secondary" data-automation-id=
"btn-footer-save" data-dojo-attach-event="onclick:saveAndStayPressed"
 data-qbo-bind="visible:shouldShowSaveAndStayButton" style>Save</button>

Try this:

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



wait = new WebDriverWait(driver, 20)
wait.until(EC.element_to_be_clickable((By.XPATH, "//button[contains(text(),'Save')]"))).click()

The element gets wrapped in a WebDriverWait until it is interactable, in this case clickable
