Hello  @samarm,

I am not sure if you have tried it this way using javascript but it seems to have worked for someone else:

1) Add a Data Label to the Form

2) Change it to Visible - No, Literal - Yes

3) Add the following code to the Data Label Text: 

<script> window.onbeforeunload = function(e) {return 'Are you sure? You will lose your data.';};</script>
