Clear Script/Function/Interval on leave page

jmoeller — Mon, 14 Sep 2020 12:24:02 GMT

Hey guys,

I'm running a script with sets an interval to reload an alv every x minutes.

I now have the problem, that the function/script still seems to run, even when I route to another page of the flavor.

This is the error i get:

And the pages leaves in this loading state until I refresh with F5.

Any tips?

Regards,
Julian

Hi Julian,

You need to leverage the window clearInterval() method to cancel the timer in case the context changes.

You can read and store the ABAP program/number pair through the scripting API and compare the context in an onAfterRefresh script. If the context has changed, call the clearInterval method with the given timer ID to cancel the scheduler.

Thank you!

Hi Krists,

thanks for your fast reply. So, my futher questions are:

1.) Were do I get the ABAP program/number pair from?

2.) Do I have to call the onAfterRefresh of the current or next screen?

3.) I don't see where I can give my timer an ID. Where can I set this?

Regards,

Julian

Hi Julian,

I think, it would be faster to have a call tomorrow or some other day. Please send me an e-mail to: krists.magons@sap.com and we will set-up a screen sharing session.

Thank you!
