javascript - Angular pass dynamic scope to directive -


i have directive takes attribute value http call so:

controller

app.controller("homecontroller", function($scope){   $http.get("/api/source").then(function(res){     $scope.info = res.data   }); });

html

<div ng-controller="maincontroller">   <ng-mydirective data-info="{{info}}"></ng-mydirective> </div>

directive:

app.directive("ngmydirective", function(){   return {     restrict: "e",     templateurl: "/partials/info.html",      link: function(scope, element, attrs){       scope.info = attrs.info;     }   } });

i'm trying pass info variable controller, directive, through attribute. doesn't work because variable value created asynchronous http call, @ time directive created, there no value.

is there way this?

you can observe attribute's value:

link: function(scope, element, attrs){       attrs.$observe('info', function(val) {         scope.info = val;       }) }

also, if can change directive scope isolated, can binding values:

app.directive("ngmydirective", function(){   return {     restrict: "e",     scope: {info: '='},     templateurl: "/partials/info.html",      link: function(scope, element, attrs){      }   } });  <div ng-controller="maincontroller">    <ng-mydirective info="info"></ng-mydirective> </div>
