Javascript to check particular layer is available in the Artwork or not

[Surya24]

Hello Everyone,

Currently, I am using the script to hide the Layer "TB"  and lock all layers in the active document:

var document = app.activeDocument;

document.activeLayer = document.layers["TB"]
document.activeLayer.visible = false;

var lc = document.layers.length;
for (var i=1; i<=lc; i++) {
document.layers[i-1].locked = true;
}

But in some cases, my document doesnot have the "TB " layer, in that case i need to skip this step and need to run further. 

Please give your inputs to overcome this.

Hi,

You can use, try and catch.

var document = app.activeDocument;
try {
    document.activeLayer = document.layers["TB"];
    document.activeLayer.visible = false;
} catch (e) {

}
var lc = document.layers.length;
for (var i = 1; i <= lc; i++) {
    document.layers[i - 1].locked = true;
}
