How to change the text in a notification

Anvil Q&A

Is it possible to change the text in a notification?

I was thinking about something like this:

with Notification('Step 1') as n:
    do_step_1()
    n.text = 'Step 2'
    do_step_2()
    n.text = 'Step 3'
    do_step_3()

I don’t know if this can be done but you could do it with an alert with a label as the content and then address the label directly

The Notification doesn’t allow to use a component, the alert does, but it will stay there and would require me to create a custom form with the code to… It has to be easier.

I ended up using JQuery. Here is what I did:

# import JQuery
from anvil.js.window import jQuery as _S

# disable all the buttons, otherwise the user could interact with the 
# form while the notification is visible
self.button_x.enabled = False

# show the notification
self.notification = Notification('Hello', title='Title', timeout=0)
self.notification.show()

# hide the x button to prevent the user from closing the notification
_S('[role="alert"] [type="button"]').hide()

# store the notification text in a form attribute
self.notification_text = _S('[role="alert"] [data-notify="message"]')

# change the text, it works in the same function or in a tick event of
# a timer because it's a form attribute
self.notification_text.text('World')

# hide the notification and re-enable the buttons
self.notification.hide()
self.button_x.enabled = True
