angularjs - How to use scope in web worker using angular -

here code. getting error.please me on issue.

in controller

if(typeof(worker) !== "undefined") {     if(typeof(worker) == "undefined") {         var worker = new worker("assets/scripts/directives/custommultifilter.js");         worker.postmessage({ "getobject":scope.payloadrowcollection});           worker.onmessage = function(event) {                  console.log(event);                                                   }     }  } 

in web worker (custommultifilter.js)

self.addeventlistener("message", function(e) {   $scope.arr = [1,2,3];      postmessage($scope.arr); }, false); 

it not possible share variables between web workers , "main" script. run concurrency issues if was.

but can communicate via events:

// in worker self.postmessage('somedata);  // in angular worker.addeventlistener('message', function(e) {     console.log('worker said: ', e.data); }, false);
