No.

I do some changes in my project and then try to save it so that I can test later. But it shows above message. If I click on 'ok' button below message, the project is still in unsaved mode.

Yes, I got it.
Thanks Evgene

I got above message many times while saving my project. If I change even single letter in form and click on save it, it shows above message. What can be the reason?

Hello Evgene,
Can you please elaborate more? Exactly what code should I put in js.
and where?

I used geolocation component to capture current location. But what if i don't want to show geolocation component on app and capture user's current location. i.e. latitude and longitude.

Can we set fields as required. So that a user can not go on next page without entering something in the fields?
