I am encountering some difficulties with the functionality of the angularjs dialog

I've been attempting to integrate an AngularJS dialog feature into my application by following the examples provided on material.angularjs.org. However, despite copying everything accurately, I am unable to get it to function. Can anyone help identify what I might be overlooking?

Below is the snippet of Javascript code:

// TABLE CONTROLS GO HERE 
app.controller('AddTableController',['$scope', function($scope,$mdDialog){
        $scope.allTables = tables;
        //method to add tables 
        $scope.showAdvanced= function(ev) {
            $mdDialog.show({
              controller:DialogController,
              templateUrl:'index_directives/dialog-add-table.html',
            })
        };
}]);
//HELPER METHOD FOR THE AddTableController//////////////////////////////
function DialogController($scope, $mdDialog) {
  $scope.hide = function() {
    $mdDialog.hide();
  };
  $scope.cancel = function() {
    $mdDialog.cancel();
  };
  $scope.answer = function(answer) {
    $mdDialog.hide(answer);
  };
}

Subsequently, the function is triggered upon button click:

<md-button class="md-fab add-button" ng-click="showAlert($event)">+</md-button>

The error log in the console displays something along these lines:

TypeError: Cannot read property 'show' of undefined
    at n.app.controller.$scope.showAlert (http://localhost/angular/js/app.js:24:16)
    at ib.functionCall (https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js:199:303)
    at Ec.(anonymous function).compile.d.on.f (https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js:216:74)
    at n.$get.n.$eval (https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js:126:15)
    at n.$get.n.$apply (https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js:126:241)

Answer №1

Don't overlook the importance of including the $mdDialog dependency:

app.controller('AddTableController',['$scope', '$mdDialog', function($scope,$mdDialog){

It's easy to forget to declare dependencies when working with AngularJS, so you might find @Michael Benford's advice on this post about ng-annotate helpful.
