How could we chain $uibModal dialogs?


I am complete beginner in AngularJS. Now I want to create the chains of dialogs using ui.bootstrap $uibModal service. I want to receive the data to the dialogs from the .txt file. That means, I won't know initially the quantity of dialogs in the chain, it will depend on the .txt data. For now I tried to do that with the loop, but it`s dumb and then I won't be able to have such functional as "previous", "next", ok and cancel. Is there any wise solution to do that? Thank you in advance for the answer.

var app = angular.module('myApp', ['ui.bootstrap']);

angular.module('myApp').config(['$uibModalProvider', function($uibModalProvider) {
  $uibModalProvider.options.windowClass = 'show';
  $uibModalProvider.options.backdropClass = 'show';
}]);



app.factory('modalDialog', function($uibModal) {
    var arr_items = [];

    var showModalDialog =function(items) {
      return $uibModal.open({
         templateUrl:  'test.html', //just the dialog body for the info
         animation: true,
          size: 'sm',
          ariaLabelledBy: 'modal-title',
          ariaDescribedBy: 'modal-body',
          controller: 'dialogCtrl',
          controllerAs: "$ctrl",
          resolve: { items: function () { console.log("items before travelling" + JSON.stringify(items));
          return items; } }
        });
      
    }

     return {showModalDialog: showModalDialog};


});


app.controller('TestCtrl', function($scope, $http, modalDialog){
  $scope.cancelled = false;
  $scope.test = function(){
    $http.get('test.txt')
        .then(function(response) {
           $scope.items=response.data;
           for (var i=0; i<$scope.items.length; i++) {
            console.log($scope.cancelled); 
            if ($scope.cancelled) return ;
           var showModalDialog = function() {
              console.log("here");
              modalDialog.items = $scope.items[i];
              modalDialog.showModalDialog($scope.items[i]);
            };
            showModalDialog();
          };
        });
  };
});


app.controller('dialogCtrl', function ($scope, $uibModalInstance, items) {
  var $ctrl =this;
  console.log("here are my items" + items.request + " " + JSON.stringify(items));

  $scope.items = items;

  $ctrl.ok = function () {
    $uibModalInstance.close($scope.items);
  };

    $ctrl.cancel = function () {
      console.log("cancel");
      $scope.cancelled = true;
      return $uibModalInstance .dismiss('cancel');
  };
});

Solution

  • Here you go ! Check this plunkr.

    The main logic for loop resides in

    function initiateModal(itemList,index){
      modalDialog.showModalDialog(itemList[index]).result
        .then(function(resp){
                  if(resp === 'cancel'){ // if user cancel the process in between
                    $scope.userSeletion.length = 0;
                    return ;
                  }else if(itemList.length === (index+1)){ // for pushing the last modal data into array
                    $scope.userSeletion.push(resp);
                    return ;
                  }else{
                    $scope.userSeletion.push(resp);
                    index++;
                    initiateModal (itemList,index);
                  }
           })
    } 
    

    which waits for the promise of earlier modal to open the next one.

    For now, I am passing userInput as a data, which i can fill depending on the user form input
