ExtendScript, refer to the layer by name

[Vitaliy Grebennikov]

This script don’t work for me(

I tested it – tried to make layer with specific name to be labeled with some colour, but it doesn’t work…

var proj = app.project;

var itms = proj.items;

var itmsLen = itms.length;

var curItem, myComp;

for(var i=0; i<itmsLen; i++){

curItem = itms;

If(curItem instanceof CompItem){

If(curItem.name == “your comp name”){ //Will grab only the first name match

myComp = curItem;

break;

}

}

}

var chkLayer = myComp.layer(“Layer Name”);

if (chkLayer == undefined){

//do this

}else{

//do that

}

It seems more likely that the problem is in selecting the composition. Try to select the layer like this and see if it works. Before running the script, select your comp either in the project panel or just select the timeline.

var myComp = app.project.activeItem;
var chkLayer = myComp.layer("Layer Name");

Thx for your attention, Andrei!

I figured out why this formula didn’t work.

I tried to figure out this problem for a long time, went through many options, nothing worked, but it gave me a basic understanding of the patterns, and it turned out that the author posted this code simply with syntax errors (apparently, some text editor messed up the text).

Here is a working formula (I added a little to it so as not to mention the name several times.

var proj = app.project;
var itms = proj.items;
var itmsLen = itms.length;
var curItem = myComp;
var layerName = "/YOUR LAYER NAME/";
for(var i=0; i<itmsLen; i++){
     curItem = itms;
     if(curItem instanceof CompItem){
          if(curItem.name == layerName ){  //Will grab only the first name match
               myComp = curItem; 
              break;
              }
         }
    }
var chkLayer = myComp.layer(layerName );
if (chkLayer == undefined){
//do something
    }else{
//do something else
}
