javascript - Checking for Locked/Hidden Layers in Adobe Illustrator -

i working on script in adobe illustrator (ai), , running issue unable understand. maybe due underlying way ai works, know if there way work around this. ok, question this:

how check if sublayer in ai locked/hidden while not directly locked (top layer locked/hidden while sublayers 'inherit status').

i have script process (looping on layers) , long layer not locked/hidden. problem when top layer (parent layer) set locked or hidden, of sublayer/objects inherit trait (locked or hidden). problem having script these locked/hidden sublayers being classified visible , unlocked (or visible undefined). there way determine this?

script:

// javascript document if (app.documents.length > 0) {     var docref = app.activedocument;     var doclayers = docref.layers;     var searchtext = "";     var replacetext = "";     var found = false;      function recurselayers(currlayers) {         var length = currlayers.length;         var currentlayer = null;         var searchtext = searchtext;         var replacetext = replacetext;          try {             (var = length; i--;) {                 currentlayer = currlayers[i];                  replacename(currentlayer, searchtext, replacetext);                  if (currentlayer.layers) {                     recurselayers(currentlayer.layers);                 }             }         } catch (e) {             logger (e);         }     }      function replacename(objarray, searchtext, replacetext) {         try {             var visible = objarray.visible;             var locked = objarray.locked;             var typename = objarray.typename;             if (visible && !locked) {                 //var searchtext = "/\s*" + searchtext + "\s*\d*/";                 objarray.name = objarray.name.replace(searchtext, replacetext);             }         } catch (e) {             logger(e);         }     }       startgui();      function startgui() {          var win = new window("dialog", "replace layer name", undefined);          win.orientation = "column";         win.alignchildren = ["fill", "fill"];          // search         var searchgrp = win.add("panel", undefined, "search , replace");         searchgrp.orientation = "column";         searchgrp.alignchildren = ["fill", "fill"];          var titlemsgs = searchgrp.add("statictext", undefined, "layer name search:");         var txt_searchtext = searchgrp.add("edittext { characters: 1, justify: 'center', active: true }");          txt_searchtext.helptip = "input layer name replace";          var titlemsgr = searchgrp.add("statictext", undefined, "layer name replace with:");         var txt_replacetext = searchgrp.add("edittext { characters: 1, justify: 'center', active: true }");         txt_replacetext.helptip = "input layer name replace with";          // set first text box active         txt_searchtext.active = true;          win.addeventlistener ("keydown", function(kd) {enter(kd) });          // replace button         var replacebtn = searchgrp.add("button", undefined, "replace");         replacebtn.helptip = "replace layer name";         replacebtn.onclick = function() {             searchtext = txt_searchtext.text;             replacetext = txt_replacetext.text;              recurselayers(doclayers);             app.redraw();         }          function enter(k) {             if (k.keyname == "enter") {                 recurselayers(searchtext.text, replacetext.text);                 app.redraw();             }         }          // close button         var quitbtn = win.add("button", undefined, "close");         quitbtn.helptip = "press esc close";          // event listener quit button         quitbtn.onclick = function() {                win.close();            }            // centering & show window         win.center();         win.show();      }       // prints stack trace     function logger(e) {         var errormsg = "";          errormsg = errormsg.concat("an error has occured:\n", e.line, "\n", e.message, "\n", e.stack);         //$.writeln(errormsg);     }  } else {         alert("you not have document opened!"); } 

example: top layer (blue square) set locked (light lock symbol). while sublayers inheriting locked status (grayed out locked symbol). in ai, these sublayers considered locked, however, script labeled @ unlocked (using layer.locked).

update: working code, @ermax.

function recurselayers(currlayers) {         var length = currlayers.length;         var currentlayer = null;         var searchtext = searchtext;         var replacetext = replacetext;          try {             (var = length; i--;) {                 currentlayer = currlayers[i];                 replacename(currentlayer, searchtext, replacetext);                  if (currentlayer.layers) {                     recurselayers(currentlayer.layers);                 }             }         } catch (e) {             logger (e);         }     }      function replacename(currlayer, searchtext, replacetext) {         try {             var visible = currlayer.visible;             var locked = currlayer.locked;             var typename = currlayer.typename;             if (checklayervisibility(currlayer) && !checklayerlocked(currlayer)) {                 currlayer.name = currlayer.name.replace(searchtext, replacetext);             }         } catch (e) {             logger(e);         }     }      function checklayerlocked(layer) {         if(!layer.locked)              for(var parent = layer.parent; parent.typename=='layer'; parent = parent.parent) {                  if(parent.locked)                     return true;              }         return layer.locked;     }       function checklayervisibility(layer) {         if(layer.visible)          for(var parent = layer.parent; parent.typename=='layer'; parent = parent.parent) {              if(!parent.visible)                 return false;          }         return layer.visible;      } 

you can check sublayer visible status checking status in parent layers, if 1 of them hidden, hence sublayer hidden:

function checklayervisibility(layer) {     if(layer.visible)      for(var parent = layer.parent; parent.typename=='layer'; parent = parent.parent)     {          if(!parent.visible)             return false;      }     return layer.visible;  }  

for locked/unlocked status same way:

function checklayerlockedstatus(layer) {     if(!layer.locked)      for(var parent = layer.parent; parent.typename=='layer'; parent = parent.parent)     {          if(parent.locked)             return true;     }     return layer.locked;  }
