javascript - How to access a factory data object inside of a $routeProvider config in Angular.JS? -

i trying create angular.js calculator, return user root page if factory data object empty. issue cannot figure out how access data.terms object see if empty inside of $routeprovider configuration under /condition path.

in code below, section says if (!data.terms) not working. want return value of terms stored in factory data function:

// creating module var myapp = angular.module("app-calculator", ["calculatorcontrols", "ngroute"])     .config(function ($routeprovider) {          $routeprovider.when("/", {             controller: "termscontroller",             controlleras: "vm",             templateurl: "/content/templates/termsview.html"         });          $routeprovider.when("/condition", {             controller: "conditioncontroller",             controlleras: "vm",             templateurl: "/content/templates/conditionview.html",             resolve: {                 mess: function ($location) {                      // check if data.terms field has been completed,                     // if not return root path.                     if (!data.terms) {                         $location.path('/');                     }                     //                  }             }         });  // data myapp.factory('data', function () {     var terms = '';      return {         terms: terms,     } }) 

you should inject data dependency in resolve section.

var myapp = angular.module("app-calculator", ["calculatorcontrols", "ngroute"])     .config(function ($routeprovider) {          $routeprovider.when("/", {             controller: "termscontroller",             controlleras: "vm",             templateurl: "/content/templates/termsview.html"         });          $routeprovider.when("/condition", {             controller: "conditioncontroller",             controlleras: "vm",             templateurl: "/content/templates/conditionview.html",             resolve: {                 mess: function ($location, data) {                      // check if data.terms field has been completed,                     // if not return root path.                     if (!data.terms) {                         $location.path('/');                     }                     //                  }             }         });
