Hi. There's a lot of searching in the community.
I'm trying to solve the problem below using a script.

 

I want to put the indicator in a specific layer and finish the work area end.

For example, as shown in the attached photo,
When there's a layer of '01~06', I want to set the working area only to the activated '01~04' layer.

 

What method and script should I write to solve my problem?

More like this then, maybe:

var myComp = app.project.activeItem;
var maxLayer = null;
for (var i = 1; i <= myComp.numLayers; i++){
	if (myComp.layer(i).hasVideo && myComp.layer(i).enabled){
		if (maxLayer == null){
			maxLayer = myComp.layer(i);
			continue;
		}
		if (myComp.layer(i).outPoint > maxLayer.outPoint){
			maxLayer = myComp.layer(i);
		}
	}
}
if (maxLayer != null){
	myComp.time = maxLayer.outPoint;
	myComp.workAreaStart = 0;
	myComp.workAreaDuration = maxLayer.outPoint;
}

It could be something like this, for this specific example, but it could be a lot more complicated, depending on exactly what the rules are:

var myComp = app.project.activeItem;
try{
	var myLayer = myComp.layer("04.jpg");
	myComp.time = myLayer.outPoint;
	myComp.workAreaStart = 0;
	myComp.workAreaDuration = myLayer.outPoint;
	for (var i = 1; i < myLayer.index; i++){
		if (myComp.layer(i).hasVideo){
			myComp.layer(i).enabled = false;
		}
	}
}catch(e){
}

    @Dan Ebberts 

    Thank you, Dan.
    var myLayer = myComp.layer("04.jpg");
    Do not enter "04.JPG" directly in the syntax;
    Is there a way to specify only the layer with the show icon on the left?
