                   <p>Country</p>
                   <select id="countryMobile" ng-model="countryMobile" class="select-styled" name="countryMobile" required>
                       <option ng-repeat="country in countries" value="{{country.id}}">{{country.name}}</option>

             <div class="modal-footer">
                 <input type="button" ng-click='confirm()' value="OK"/>
                <input type="button" ng-click='cancel()' value="Cancel"/>
             </div>
         </form>
     </script>

</form>


   $rootScope.openMobileUpdateModal = function () {

      $rootScope.countryMobile = $rootScope.country;
      var modalInstance = $modal.open({
        templateUrl: 'mobileModal.html',
        controller: ModalInstanceCtrl
      });
    };
    var ModalInstanceCtrl = function ($rootScope, $modalInstance) {
        $rootScope.confirm = function () {
         //do something
          $modalInstance.close();
        };
        $rootScope.cancel = function () {
          $modalInstance.dismiss();
        };
    };

Anyone know how to send value from $rootScope to modal, and set that value as default? Thanks

Answer 1

First of all there is syntax error you have double quote twise in you select tag code. Update it as below then try. And use $root in your ng-model.

<select id="countryMobile" ng-model="$root.countryMobile" class="select-styled" name="countryMobile" required>
      <option ng-repeat="country in countries" value="{{country.id}}">{{country.name}}</option>
</select>

I'm not sure that I understand your problem correct but try do not use rootScope or modify and avoid rootScope modification.

If you need use some value from rootScope:

1. extract this value to local scope of particular controller and after that use it
2. Use WATCH operator to avoid situations when you render some value before it initialised.

<option ng-repeat> does not work in angularjs. you should use

<select id="countryMobile" ng-model="countryMobile" class="select-styled"   name="countryMobile" required ng-options="country.id as country.name for country in contries"></select>
