Create a loading screen while clicking on UI action

[Nikhil65]

I have a heavy JS code which would take approx couple of mins to run.
Hence, I would like to show a dialog box(Loading Screen) to the user while the code is being run.

The Code will get triggered by a UI action button, and it would invoke a script include.

Is there a way to get the loading screen for the user, on clicking the UI action?

You can use GlideModal to show the dialog.

GlideModal doc: https://developer.servicenow.com/dev.do#!/reference/api/quebec/client/r_GMODV3-setWidth_S

Refer below link to add the loader:
