How to make the layer visible on and off

Hi, experts

this is my script:

        var docs = app.documents;

             for (var i = docs.length-1; i >= 0; i--) {

                    docs.layers.item("Chi").visible = true;

                    docs.layers.item("Chi").locked = false;

                    docs.layers.item("Eng").visible = false;

                    docs.layers.item("Eng").locked = true;

                     }

      alert("Done.")

but how can make the layer

1. if the layer "chi" visible = true; while "eng" visible = false

"chi" locked = false; while "eng" locked = true

just to turn the

layer "chi" visible = false; while "eng" visible = true 

"chi" locked = true; while "eng" locked = false

just like two layer switch;

regard

Try this,

var docs = app.documents;
for (var i = docs.length-1; i >= 0; i--) {
    if(docs.layers.item("Chi").visible == true && docs.layers.item("Chi").locked == false)
    {
        docs.layers.item("Chi").visible = false;
        docs.layers.item("Chi").locked = true;
        docs.layers.item("Eng").visible = true;
        docs.layers.item("Eng").locked = false;
    }
    else if(docs.layers.item("Eng").visible == true && docs.layers.item("Eng").locked == false)
    {
        docs.layers.item("Chi").visible = true;
        docs.layers.item("Chi").locked = false;
        docs.layers.item("Eng").visible = false;
        docs.layers.item("Eng").locked = true;
    }
}
alert("Done.")

    Couple of things to note:

    1. You should get layer by name layer.itemByName

    2. Consider reuse and error handling

    You can modify below code if you think your requirement is not translated.

    // Toggle between Chi and Eng layers

    function toggleLayers() {

         var total = app.documents.length;

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

              var doc = app.documents.item(i);

              var chiLayer = doc.layers.itemByName("Chi");

              if(chiLayer && chiLayer.isValid && chiLayer.visible) {

                   lockLayer(doc, "Eng");

                   unlockLayer(doc, "Chi");

              } else {

                   lockLayer(doc, "Chi");

                   unlockLayer(doc, "Eng");

              }

         }

    }

    // Lock layer and make it invisible

    function lockLayer(doc, layerName) {

         try{

              var layer = doc.layers.itemByName(layerName);

              if(layer && layer.isValid) {

                   layer.visible = false;

                   layer.locked = true;

              }

         }catch(e) { }

    }

    // Unlock layer and make it visible

    function unlockLayer(doc, layerName) {

         try{

              var layer = doc.layers.itemByName(layerName);

              if(layer && layer.isValid) {

                   layer.visible = true;

                   layer.locked = false;

              }

         }catch(e) {}

    }

      Like this maybe ?

      var main = function() {
        var docs = app.documents,
        layers,
        n = docs.length,
        chi, eng;
        while ( n-- ) {
        layers = docs.layers;
        chi = layers.item("Chi");
        eng = layers.item("Eng");
        if ( chi.isValid && eng.isValid ) {
        eng.visible = chi.locked = !chi.visible;
        eng.locked = chi.visible;
        }
        }
      }
      main();
