Need Notification for attaching the handler On Closing of the HTML Extension in Indesign CC 2014
I need to process a couple of tasks after clicking on cross button(on top right corner of HTML extension) and before the Extension actually gets closed.
As I Understand, Extension is using chromium browser.
I tried attaching an event listener to "onbeforeunload" event of chrome but it suppresses any alerts being thrown and closes the extension, without waiting for
background processes to complete.
Is there a way through scripting/Plugin or any other way to achieve it?
