Identifying the order of the active layer

[Shulipa Bernad]

Good afternoon everyone!
If the active layer is the 3rd in order, then do something.
It would be something I'm looking for. Thank you!

Are you familiar with JavaScript? 

[Shulipa Bernad]

Minimum knowledge possible. Any suggestions friend?

[Bojan Živković]

You can't accomplish that task using conditional actions which has limited set of conditions but not one that you need.

[Shulipa Bernad]

It is a pity that I cannot achieve such conditions. I am grateful for your attention.

I have achieved this so far: I think that would be enough.

if(app.activeDocument.activeLayer.id == 3){alert ("OK!")} else{alert ("false")}

[c.pfaffenbichler]

Have you tested that piece of code yet? 

[Shulipa Bernad]

Hi c.pfaffenbichler I tested it, it worked fine. I had to use a script loop, but it would be necessary to add an extra function only in order 3 layer. Obtaining the ID of this layer I achieved my goal.

id != number in order

[c.pfaffenbichler]

Yeah, at least in AM code the itemIndex gives the position in the stack while the identifier is a unique number. 

[jazz-y · Accepted solution]

if(app.activeDocument.layers[app.activeDocument.layers.length- 3] == app.activeDocument.activeLayer) {alert ("OK!")} else {alert ("false")}

Thank you jazz-y

I don't think AM code would be needed, like jazz-y pointed we can reliably use the layers array. I also used the same approach in the discussion i mentioned below. Everything seemed to work fine the last time i checked. Do you see any cases that would be missed without AM

Thanks for suport Manan Joshi

See the following discussion, it will give you an idea on how to manipulate the layer order. It has code snippet for handling cases of layer groups as well
