angularjs - How to get input values outside the custom directive -


i need input values outside directive(num1,num2) count result in it(addition) on click button. proper way it? here html

<div ng-app="sumapp" >   <div ng-controller='sumappctrl' >      <input  ng-model='num1' type='text'  >     <span>+</span>     <input   ng-model='num2'  type='text'>     <span>=</span>     <bp-sum></bp-sum>     <input type="button" value="sum" ng-click="sumnumbers(num1,num2)" />    </div> </div>

and js code:

var sumapp = angular.module('sumapp', []);  sumapp.controller("sumappctrl", function ($scope) {  });   sumapp.directive('bpsum',function( ){  return  {      restrict:'e',     controller:         sumnumbers = function(num1,num2){          var items=[parseint(num1),parseint(num2)];         $scope.addition = _.reduce(items, function(memo, num){ return memo + num; }, 0);     },     template:"<input type='text' ng-model='addition' />"  }   })

according me..you should develop component addition this

<div ng-app="sumapp" >   <div ng-controller='sumappctrl' >       <bp-sum></bp-sum>     </div> </div>

directive

    sumapp.directive('bpsum', function() {      return {          restrict: 'e',         controller: function($scope) {              $scope.sumnumbers = function(num1, num2) {                  var items = [parseint(num1), parseint(num2)];                 $scope.addition = _.reduce(items, function(memo, num) {                     return memo + num;                 }, 0);             };          },         template: " <input  name='num1' ng-model='num1' type='text'  >" +             "<span>+</span>" +             "<input   name='num2' ng-model='num2'  type='text'>" +             "<span>=</span><input type='button' value='sum' ng-click='sumnumbers(num1,num2)'' />"+             "<label>sum : </label> <input type='text' ng-model='addition' />"       };   });
