AngularJS open modal from controller

Question

I am new to angularjs, and writing an application where a template(inventory.html) containing grid is opened with , it has a validate button at bottom of grid, which calls validate() to validate selected grid rows, before that i need a modal to popup and take user name as input and then process further.

my validate function is inside controller of template(i.e. inventory.html) . I have a app.js which contains routing info and controller.js which contains controllers for all templates.

My question is, if there is any way that I can open modal from validate(), take user input and proceed further without writing separate controller for modal. (I have a separate userinput.html for modal.)

(Sorry If my question is not clear. Plz help I am stuck with this and have tried many options from web)

// This is my controller

var app = angular.module('app', []);
app.controller('InventoryCtrl',['$scope','$location','$http','$modal',function($scope, $location, $http,$modal{console.log("Inside inventory ctrlr");

 // Validate Function for validate button click
 $scope.validate = function() 
    {   
        $scope.user = null;
        $scope.build = null;
        // Show modal to take user inputs for environment
        var modalInstance = $modal.open(
        {
            controller : "inputModalCntrl",
            templateUrl : "../partials/addEnvironment.html",
            resolve: {
                $callback: function () {
                    return function(param,user,build){
                        /* This function print value(param) dispached in modal controller */
                        console.log(param,user,build);
                                    $scope.user = user;
                                    $scope.build = build;
                    };
                },
                $send: function(){
                    return function(){
                        /* This function send param for the modal */
                        return {param1:"Hello Word Main"};
                    };
                }
            }
        });
// This is further process of function
     postdata = {};
     var dlist = $scope.gridApi.selection.getSelectedRows();
        postdata['dlist'] = dlist;
     $http({ url: "/api/check",  data: postdata, method: "POST" })
    .success(function (response) { alert(response);})
    .error(function () { alert('Error getting data');});
 };
   }]);

and this is modal controller

app.controller("inputModalCntrl", function($scope, $modalInstance, $callback, $send) {
$scope.init = function(){
    /* This function print value(param) dispached in main controller */
    console.log($send);

    /* This send data to main controller */
    $callback({param1:"Hello Word Modal", user :user, build : build});
};
});

Solution 1

I would strongly suggest you write a separate controller for you modal. That will greatly help you to maintain your code later.

If I understand correctly (from your tags) you use an this one: https://angular-ui.github.io/bootstrap/ From your main controller, open the modal:

var modalInstance = $modal.open({
      animation: $scope.animationsEnabled,
      templateUrl: 'myModalContent.html',
      controller: 'ModalInstanceCtrl',
      size: size,
      resolve: {
        items: function () {
          return $scope.items;
        }
      }
    });

note the resolve function, you can pass extra parameters like this to modal controller.

In modal controller:

angular.module('your.awesomeApp').controller('ModalInstanceCtrl', function ($scope, $modalInstance, items) {

note the third parameter, it will be values, that you have passed.

Solution 2

You can use ui.bootstrap's components which include a modal. You won't have to use a separate controller.
