I am uplifting a chat application from AngularJS to VueJS and I don't have much clue about how the AngularJS. There isn't really a great resources available on AngularJS right now to gain some insight.
If someone could help me in this I'd really appreciate it.
I wish to convert this below AngularJS code to VueJS completely.
var app = angular.module('IBMfinder', ['ngRoute']);

Try to search on google first.
If you can't understand something ask a concrete question with an example (it doesn't have to be the full code) so we can help you better.
I don't know if you have experience with Vue.js, I can tell you worse what those tutorials will explain way better. AngularJS uses a different approach than Vue, Angular 2+ or React.
Those frameworks use a component approach so you divide the app into multiple components that have properties.
Angular use an MVC-ish approach, you define modules with angular. module those modules can have external or core dependencies defined in the array.
A module can have a router, a router will define the views and the controller of each view. The views have angular directives and HTML, and the controllers have the logic.
Use one of those tutorials to learn more.
I am trying to pre-load data based on ng-controller attributes prior to displaying the html and in turn prior to button click(submit). I am new to angular js and not sure how to accomplish the task.
There will be one question and n number of answer options
May last try is as seen in code but I need to get to the controller other than button click. I need to see the question and possible answers before the html is present.

I have a function which updates the object, the problem is when I go back from the update form field to the detailed view, it initializes the old object instead of the updated object.
I want to populate the cars list in the CarService instead of the app.js
This is my carService:
window.app.service('CarService', ['HTTPService', '$q',
'$http', function (HTTPService, $q, $http) {
'use strict';
this.cars = [];
this.get = function () {
var deferred = $q.defer();
HTTPService.get('/car').then(function resolve(response) {
deferred.resolve(response.data);
}, function reject(response){
deferred.reject(response);
});
};
this.add = function (formCar) {
var deferred = $q.defer();
console.log("CarService response 1 : ");
$http.post('/#/car', formCar).then(function resolve(response){
deferred.resolve(response.data);
}, function reject(response){
deferred.reject(response);
});
return deferred.promise;
};
this.showDetails = function (carId){
var deferred = $q.defer();
$http.get('/car/view/{{carId}}').then(function resolve(response){
HTTPService.get('/car/view/' + carId).then(function
resolve(response) {
deferred.resolve(response.data);
}, function reject(response){
deferred.reject(response);
});
return deferred.promise;
};
this.put = function (carformUpdate, opleidingsprofielId) {
var deferred = $q.defer();
$http.put('/#/car/:carId/update', carformUpdate).then(function resolve(response){
deferred.resolve(response.data);
}, function reject(response){
deferred.reject(response);
});
return deferred.promise;
};
}]);
This is my updateCar controller:
window.app.controller('updateCarCtrl', ['$scope', '$routeParams',
'CarService', '$location', function ($scope, $routeParams, CarService,
$location) {
'use strict';
$scope.carId = $routeParams.carId;
initCar($scope.carId);
function initCar(carId) {
CarService.showDetails(carId).then(function success(car) {
$scope.car = car;
}, function error(response) {
});
}
$scope.updateCar = function (carId) {
carId = $scope.carId;
if($scope.car !== null){
CarService.put($scope.car, carId).then(function
success(response) {
$scope.car = response;
$location.path('/car/view/' + carId);
alert("Car updated");
}, function error(response) {
$scope.error = response.statusText;
$scope.myform = {};
});
}
};
}]);
This is my carView controller:
window.app.controller('carViewCtrl', ['$scope', '$routeParams', '$location',
'CarService', function ($scope, $routeParams, $location, CarService) {
'use strict';
$scope.carId = $routeParams.carId;
initCar($scope.carId);
function initCar(carId) {
CarService.showDetails(carId).then(function success(car) {
$scope.car = car;
}, function error(response) {
});
}
}]);
My carView initializes the object again when it gets redirected with $location.path('/car/view/' + carId); but as the original object and not the updated object.
I'm trying to do this on an ngMock backend.
My app.js looks like this:
App.js
routing:
.when('/car', {
templateUrl: 'pages/car/car.html'
})
.when('/car/view/:carId', {
templateUrl: 'pages/car/carView.html',
controller: 'carViewCtrl',
controllerAs: 'ctrl'
})
.when('/car/addCar', {
templateUrl: 'pages/car/carAdd.html'
})
.when('/car/:carId/update', {
templateUrl: 'pages/car/carUpdate.html',
controller: 'updateCarCtrl',
conrtollerAs: 'ctrl'
})
app.run: this is where my mock backend is defined
window.app.run(function($httpBackend) {
var cars = [
{
id: 0,
name: ‘car0’,
address: 'adress0',
tel: 'tel0',
email: 'email0'},
{
id: 1,
name: ‘car1’,
address: 'adress1',
tel: 'tel1',
email: 'email1'
}];
var carUrl = “/#/car”;
$httpBackend.whenGET(carUrl).respond(function(method,url,data) {
return [200, cars, {}];
});
$httpBackend.whenGET(/\/#\/car\/view\/(\d+)/, undefined,
['carId']).respond(function(method, url, data, headers, params) {
return [200, cars[Number(params.carId)], {
carId : params.carId
}];
});
$httpBackend.whenPUT('/#/car/:carId/update').respond(function(method, url,
data, carId) {
var car = angular.fromJson(data);
return [200, car, {}];
});
Thanks for any help!
It looks like your update function calls the CarService.put, which in turn calls a HTTPService.put. In your mocked backend you have this:
$httpBackend.whenPUT
-> add new car;
So it always adds a new car, and doesn't update one. This means that when you do the get, you probably get the first car back that matches the given id, which isn't the updated one.
In pseudo code:
// carService.cars = [{id:1,name:"name"}]
var myCar = carService.get(1); // returns {id:1,name:"name"}
myCar.name = "otherName";
carService.put(car); // -> cars.push(car); -> cars = [{id:1,name:"name"},{id:1,name:"otherName"}]
goToDetails(1);
var myCar = carService.get(1); // iterate over the cars, and return the one with id = 1,
// which is {id:1,name:"name"}
I have this in the controller
angular.module('myApp')
.controller('TaskController', function ($scope, TaskFactory) {
$scope.addTodo = function () {
$scope.todos.push({text : $scope.formTodoText});
$scope.formTodoText = '';
};
});
and this in the factory
angular.module('myApp')
.factory('TaskFactory', function ($q, $http) {
var sendTasks = function(params) {
var defer = $q.defer();
console.log(1, params);
$http.post('http://localhost:3000/task/save', params)
.success(function(data) {
console.log(2);
console.log('data', data);
})
.error(function(err) {
defer.reject(err);
});
return defer.promise;
}
return {
sendTask: function(taskData) {
console.log('taskData', taskData);
return sendTasks('/task/save', {
taskData : taskData
})
}
}
});
all I need is to know, how to send the data from the controller to the factory in order to do the POST to the specified route ?
You just need to call the function/method inside factory with the required params.
angular.module('myApp')
.controller('TaskController', function ($scope, TaskFactory) {
$scope.addTodo = function () {
$scope.todos.push({text : $scope.formTodoText});
TaskFactory.sendTask({data : $scope.formTodoText})
$scope.formTodoText = '';
};
});
You can follow Dan Wahlin blog post.
Controller:
angular.module('customersApp')
.controller('customersController', ['$scope', 'dataFactory', function ($scope, dataFactory) {
$scope.status;
dataFactory.updateCustomer(cust)
.success(function () {
$scope.status = 'Updated Customer! Refreshing customer list.';
})
.error(function (error) {
$scope.status = 'Unable to update customer: ' + error.message;
});
}
Factory:
angular.module('customersApp')
.factory('dataFactory', ['$http', function($http) {
var urlBase = '/api/customers';
dataFactory.updateCustomer = function (cust) {
return $http.put(urlBase + '/' + cust.ID, cust)
};
}
Hope that solve your problem.
You can call the function directly on the TaskFactory that you pass into the controller as a dependency.
I've cleaned up your code a bit and created a plunk for you here:
And here's the code:
Controller
(function(angular) {
// Initialise our app
angular.module('myApp', [])
.controller('TaskController', function($scope, TaskFactory) {
// Initialise our variables
$scope.todos = [];
$scope.formTodoText = '';
$scope.addTodo = function() {
// Add an object to our array with a 'text' property
$scope.todos.push({
text: $scope.formTodoText
});
// Clear the input
$scope.formTodoText = '';
// Call function to send all tasks to our endpoint
$scope.sendTodos = function(){
TaskFactory.sendTasks($scope.todos);
}
};
});
})(angular);
Factory
(function(angular) {
angular.module('myApp')
.factory('TaskFactory', function($q, $http) {
var sendTasks = function(params) {
var defer = $q.defer();
$http.post('http://localhost:3000/task/save', params)
.success(function(data) {
console.log('data: ' + data);
})
.error(function(err) {
defer.reject(err);
});
return defer.promise;
}
return {
sendTasks: sendTasks
}
});
})(angular);
I am working with wordpress' rest api and I am extracting a list of posts which allow the user to see a single post. Now I want to include the comments as well but I cannot wrap my head around this. I am using a factory for the calls:
.factory('Articles', function ($http) {
var articles = [];
storageKey = "articles";
function _getCache() {
var cache = localStorage.getItem(storageKey );
if (cache)
articles = angular.fromJson(cache);
}
return {
all: function () {
return $http.get("http://www.examplesite.com/tna_wp/wp-json/posts?filter[category_name]=test").then(function (response) {
articles = response.data;
console.log(response.data);
return articles;
});
},
get: function (articleId) {
if (!articles.length)
_getCache();
for (var i = 0; i < articles.length; i++) {
if (parseInt(articles[i].ID) === parseInt(articleId)) {
return articles[i];
}
}
return null;
}
}
})
My controller:
.controller('ExampleCtrl', function ($scope, $stateParams, _, Articles) {
$scope.articles = [];
Articles.all().then(function (response){
$scope.articles = response;
window.localStorage.setItem("articles", JSON.stringify(response));
},
function (err) {
if(window.localStorage.getItem("articles") !== undefined) {
$scope.articles = JSON.parse(window.localStorage.getItem("articles"));
}
}
);
$scope.doRefresh = function() {
Articles.all().then(function (articles){
var loadedIds = _.pluck($scope.articles, 'id');
var newItems = _.reject(articles, function (item){
return _.contains(loadedIds, item.id);
});
$scope.articles = newItems.concat($scope.articles);
$scope.$broadcast('scroll.refreshComplete');
});
};
})
//THIS IS WHERE I AM TRYING AND FAILING
.controller('ExampleInnerCtrl', function ($http, $scope, $stateParams, $cordovaSocialSharing, $ionicModal, Articles) {
$scope.article = Articles.get($stateParams.articleId);
var url = Articles.get($stateParams.articleId);
$scope.comments = [];
$http.get("http://www.example.com/tna_wp/wp-json/posts/" +url+ "/comments").then(function (response, commentId) {
$scope.comments = response.data;
console.log(response.data);
return $scope.comments;
});
$scope.comment = $stateParams.commentId;
$ionicModal.fromTemplateUrl('gauteng-comments.html', {
scope: $scope,
animation: 'slide-in-up'
}).then(function(modal) {
$scope.modal = modal
})
$scope.openModal = function() {
$scope.modal.show()
}
$scope.closeModal = function() {
$scope.modal.hide();
};
$scope.$on('$destroy', function() {
$scope.modal.remove();
});
$scope.sharePost = function(link){
window.plugins.socialsharing.share('I just read this article on The New engage: ', null, null, "http://example.com" + link);
};
})
now in the controller if I include the post id manually I can get the comments for that post, however I cannot seem to store that post ID in a variable to use
--------EDIT
.config(function ($stateProvider, $urlRouterProvider) {
$stateProvider
.state('app', {
url: "/app",
abstract: true,
templateUrl: "templates/menu.html",
controller: "NavCtrl"
})
.state('app.home', {
url: "/home",
views: {
'menuContent': {
templateUrl: "templates/home.html"
}
}
})
.state('app.provinces', {
url: "/provinces",
views: {
'menuContent': {
templateUrl: "templates/provinces.html"
}
}
})
.state('app.example', {
url: "/provinces/example",
views: {
'menuContent': {
templateUrl: "templates/example.html",
controller: "ExampleCtrl"
}
}
})
.state('app.exampleSingle', {
url: "/provinces/example/:articleId",
views: {
'menuContent': {
templateUrl: "templates/exampleSingle.html",
controller: "ExampleInnerCtrl"
}
}
})
;
$urlRouterProvider.otherwise("/app/home");
});
Ok it was my stupidity... I just stored the variable as: var url = $scope.article.ID;
