1. hide your original button
2. create a new button that open your confirmation modal
3. if accepted, generate a click to the real hidden button. Eg: $("#myHiddenButton").trigger('click')

done

$("input[name='EMAIL']").val()

Thanks a lot Joseph for the example, so not javascript but jQuery actually, I see.

I tried with jQuery to get the parent element ID but it also did not work:
$(this).parent().attr('id')

Did you try on your side? Here is how to reproduce:

• Create a button section, give it an ID (edit element -> identification)
• Add a button in this section and create a cloud backend action
• Before the function call, check the box "execute a javascript" and add a code to trigger a confirmation pop up for e.g. Put the parent ID in that pop up:

//I tried this: 
var id = this.parentElement.id
//and this:
var id = $(this).parent().attr('id')

confirm(id)

Let me know if you succeed and how!
Thanks!
