javascript - Pass variable from directive to controller -

i have directive definition , want pass currentscriptpath testcontroller.

how do that?

(function(currentscriptpath){     angular.module('app', [])         .directive('test', function () {             return {                 restrict: 'e',                 scope: {},                 templateurl: currentscriptpath.replace('.js', '.html'),                 replace: true,                 controller: testcontroller,                 controlleras: 'vm',                 bindtocontroller: true         };     }); })(     (function () {         var scripts = document.getelementsbytagname("script");         var currentscriptpath = scripts[scripts.length - 1].src;         return currentscriptpath;     })() );  testcontroller.$inject = ['$scope'];  function testcontroller($scope) {     // try access $scope.currentscriptpath here } 

as want access currentscriptpath in directive controller. need attach variable current scope inside link function of directive & scope make currentscriptpath available controller testcontroller scope because have used bindtocontroller: true, in directive.

markup

<div ng-controller="ctrl">     <test></test> </div> 

directive

(function(currentscriptpath) {     angular.module('app', [])     .directive('test', function() {       return {         restrict: 'e',         scope: {},         templateurl: currentscriptpath.replace('.js', '.html'),         replace: true,         controller: testcontroller,         controlleras: 'vm',         bindtocontroller: true,         link: function(scope, element, attrs) {           scope.currentscriptpath = currentscriptpath; //will update value of parent controller.         }       };     }); })(   (function() {     var scripts = document.getelementsbytagname("script");     var currentscriptpath = scripts[scripts.length - 1].src;     return currentscriptpath;   })() ); 

controller

function testcontroller($scope, $timeout) {   var vm = this;   $timeout(function() {     alert($scope.currentscriptpath) //gets called after link function initialized   }) }
