Is there any way to identify what property is selected with scripting?

[zachneel]

I'm writing a script to be able to change the value of a property based on a user input, and I'm wondering if there's a way to identify exactly what property is selected.

I mainly want to identify if they have scale selected so that instead of needing to input an x and y value you can just input one so it'll slot into both spots.

In your curent composition, you can retrieve an array of selected properties with: app.project.item(index).selectedProperties

Or on a layer, with  app.project.item(index).layer(index).selectedProperties

More info here: https://ae-scripting.docsforadobe.dev/layers/layer/#layer-selectedproperties and here https://ae-scripting.docsforadobe.dev/items/compitem/#compitem-selectedproperties

Thanks for the quick reply Tomas! I know you can get an array of selected properties, but I'm more wondering if there's some of way of specifically seeing if one of those is the scale property for example.

something like:

var props = app.project.activeItem.selectedProperties;
for (i=0; i<props.length; i++)
     {
      if (props[i]==scale)
           {
            do something
            }
     }

 Obviously I know it wouldn't be this exactly I'm just wondering if I can do something along these lines

you can check the matchName of the property

if(props[i].matchName == "ADBE Scale") {...}
