angularjs view not getting updated

angularjs view not getting updated - javascript

Here is a small self-contained html todo application using routes...
It has two views - list.html and add.html
list.html:
<div>
Add Task
<br />
<br />
<div class="container" id="tasks">
<ul>
<li ng-repeat="task in tasks">
<button ng-show="!task.done" ng-click="markTaskAsDone(task)" class="btn btn-default btn-xs"><span class="glyphicon glyphicon-ok-circle"></span></button>
<button ng-show="task.done" ng-click="markTaskAsNotDone(task)" class="btn btn-default btn-xs"><span class="glyphicon glyphicon-pushpin"></span></button>
<button ng-click="removeTask(task)" class="btn btn-default btn-xs"><span class="glyphicon glyphicon-remove-circle"></span></button>
<s ng-show="task.done">{{task.desc}}</s>
<span ng-show="!task.done">{{task.desc}}</span>
</li>
</ul>
<p ng-show="tasks.length == 0">Add few tasks</p>
</div>
</div>
add.html:
<div>
<span class="glyphicon glyphicon-arrow-left"></span> Back
<h2>Add a task</h2>
<div class="form-inline">
<input type="text" data-ng-model="newTask.desc" placeholder="Enter Task..." class="form-control" />
Add
</div>
</div>
I only have one controller.
controllers = {
ToDoController: function ($scope, $timeout, $location) {
//two items in by default...
$scope.tasks = [
{ desc: 'Buy milk', done: false },
{ desc: 'Collect newspaper', done: false }
];
$scope.newTask = { desc: '', done: false };
$scope.addNewTask = function () {
$location.path('/');
console.log('a');
$scope.tasks.push($scope.newTask);
}
$scope.markTaskAsDone = function (task) {
task.done = true;
console.log($scope.tasks);
}
$scope.markTaskAsNotDone = function (task) {
task.done = false;
};
$scope.removeTask = function (task) {
$scope.tasks.splice($scope.tasks.indexOf(task), 1);
};
//called to set newTask
$scope.setNewTask = function () {
$scope.newTask = { desc: '', done: false };
};
}
};
My shell page looks like this:

})
.otherwise({ redirectTo: '/list' });
});
</script>
</body>
</html>
Issue:
When I load index.html its shows the list.html. The two default items I've put shows up. I click on Add and navigate to the second view (add.html), enter details and click on the Add button in that page...I navigate to the list.html view, but its still showing the old list...not the updated list...
Surely missing some api call to do the update to the view...else this page is coming from some cache. What is the correct way to do this?

ToDoController is instantiated twice and separately for your two views. To maintain 1 instance of the controller to control both views, don't declare it in your routing, but declare it on a parent tag of the views.
For instance, like this:
<div data-ng-app="todoApp" data-ng-controller="ToDoController">
<div data-ng-view></div>
</div>
Even better is to write separate controllers for each view to put the view-specific logic into, and have 1 parent controller to store values that both controllers should have access to.
Another way to share scope among isolated controllers is using $rootScope, but you should normally try to avoid using that (like you would try to avoid using global variables in any programming language).

How can I create a modal list of values using just bootstrap and angular with springboot as a backend?

I am trying to make a generic "List of Values", a searchable modal with a natural identifier and a description. I have managed to create an angularjs app that does this in SpringBoot but it is not callable as a modal.
I want to use nothing but angularjs, bootstrap and springboot mvc, I don't want to get into node as the backend.
I attempted to follow the instructions here:
https://www.uibootstrap.net/angular-ui-bootstrap/angular-bootstrap-modal-example-demo/
But they are incomplete, code fragments. I have tried to put it all together and have the following three files:
At this point I am getting
Error: [$injector:modulerr] Failed to instantiate module TestApp due to:
[$injector:modulerr] Failed to instantiate module ui.bootstrap due to:
[$injector:nomod] Module 'ui.bootstrap' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.
I don't even know where this would get ui.bootstrap and the installation instructions for it say to use npm, I want to know what files are being used and place them in my springboot project. Npm and node are not in the architectural plans.

It seems you haven't connected linking between controller and view
The error Failed to instantiate module ui.bootstrap due to: you are getting due to it's not loaded and you are trying to use this module.
Please check below for how to show modal using ui.bootstrap
First you need to create proper directory structure in order to load files when application run in browser.
Directory structure example:
Now let's jump to index.html

That's it run this code and it will be open modal on button click
Note: This is just basic setup of angularjs. We can still improve this code if you have more features to built like routing, api calls, mvc pattern
Here is medium blog which explains some basics features of angularjs.

You need to add bootstrap script to your index.html file like <script src="https://cdnjs.cloudflare.com/ajax/libs/angular-ui-bootstrap/2.5.0/ui-bootstrap-tpls.min.js"></script>

AngularJS $location directory

Main page URL: http://localhost:3000/
Current second page URL: http://localhost:3000/#/titleDetails.html
Expected second page URL: http://localhost:3000/titleDetails.html
Currently when I click on the title in my main page, the URL contains an extra /# which causes the page to be redirected to titleDetails.html.
The directory of titleDetails.html and index.html is in the same directory.
May I know how can I fix this?

AngularJS is a SPA (single page application) oriented. Your links are still tied to the classic multiple page navigation. You will have to re-work your app since $location and $http.get are not the correct services for loading templates and navigation in your scenario.
AngularJS can load the template and update the address bar accordingly as long you use the $routeProvider. Scoth.io made a simple tutorial on how to setup routing.
But you basically have to include ngRoute to your application:
angular.module('ngRouteExample', ['ngRoute'])
Then configure your routes:
.config(function($routeProvider, $locationProvider) {
$routeProvider
.when('/', {
templateUrl: 'blogPosts.html',
controller: 'BlogController'
})
.when('/post/:id', {
templateUrl: 'titleDetails.html',
controller: 'TitleController'
});
}
Since the answer can get very long, the following Plunker demonstrates a simple routing implementation for you to learn:

How to load multiple page(cshtml) inside single page on button click with Angular.js?

I am creating crud operation in Angular.js with mvc with have following pages:
Index:This is the main page under which I want to display my list of employee page i.e _employeeList.cshtml.
AddNewEmployee.cshtml:This page will be used for creating new employee
EditEmployee.cshtml:For opening record in edit mode for particular employee.
All this pages I want to render inside Index.cshtml page i.e to create single page application.
When my page loads I want to display list of employees and when user clicks on Add Employee then I want to open new add employee page.
This is my current code:
Layout.cshmtl:
<!DOCTYPE html>
<html data-ng-app="empApp">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width" />
<title>#ViewBag.Title</title>
#Styles.Render("~/Content/css")
#Scripts.Render("~/bundles/modernizr")
<script src="~/Scripts/angular.js"></script>
</head>
<body>
#RenderBody()
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
#Scripts.Render("~/bundles/bootstrap")
#RenderSection("scripts", required: false)
</body>
</html>
Index.cshtml:
#{
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h1 style="margin-left:750px;">
List
</h1>
<input class="btn btn-primary" type="button" data-ng-click="AddEmployee()" value="Add Employee">
<div ng-controller="employeeListCtrl">
#Html.Partial("_employeeList")
</div>
<script src="~/AppScript/Module.js"></script>
<script src="~/AppScript/Service.js"></script>
<script src="~/AppScript/Employee.js"></script>
Module.js:
var app;
(function () {
app = angular.module("empApp", [])
config(function ($routeProvider) {
$routeProvider.when('')
{
}
});
})();
So basically I am stuck here. When user will click on Add Employee button, how I will load my AddNewEmployee.cshtml page in current index.cshtml page without page refresh?
Update:
Index.cshtml:
<h1 style="margin-left:750px;">
List
</h1>
<input class="btn btn-primary" type="button" data-ng-click="AddEmployee()" value="Add Employee">
#*<div ng-controller="employeeListCtrl">
#Html.Partial("_employeeList")
</div>*#
<ng-view></ng-view>
<script src="~/AppScript/Module.js"></script>
<script src="~/AppScript/Service.js"></script>
<script src="~/AppScript/EmployeeListController.js"></script>
Module.js:
var app = angular.module("empApp", ['ngRoute'])
.config(function ($routeProvider) {
$routeProvider.when('/employeelist',
{
templateUrl: 'Views/Home/_employeeList.cshtml',
controller: 'employeeListCtrl'
});
$routeProvider.otherwise({ redirectTo: '/Home' });
});
EmployeeListController:
app.controller('employeeListCtrl', function ($scope, crudService) {
alert()
});
But here my EmployeeListController doesnt gets called when my url is like this as shown in below pic and when I run my application why my url is like this as shown in below pic:

You can write a function in controller like
$scope.AddEmployee = function()
{
$location.url("AddNewEmployee");
}
After this you can check condition in config like
.when("/AddNewEmployee",{
templateUrl : "AddNewEmployee.cshtml",
controller : ""
})

Call a controller when a menu is selected in single page application - angularJs

I have created a simple Single page application with angular js. I have a index page in which the route is defined and the ng-view is called.

App.js:
var app = angular.module('app', ['ngRoute']);
// configure our routes
app.constant('routes', [
{
url: '/',
config: {
templateUrl: 'dashboard.aspx',
menuItem: 'MainPage'
}
},
{
url: '/about',
config: {
templateUrl: 'about.aspx',
menuItem: 'aboutPage'
}
},
{
url: '/contact',
config: {
templateUrl: 'contact.aspx',
menuItem: 'contactPage'
}
}
]);
app.config(['$routeProvider', 'routes', '$controllerProvider', function ($routeProvider, routes, $controllerProvider) {
//$controllerProvider.allowGlobals();
app._controller = app.controller;
// Provider-based controller.
app.controller = function (name, constructor) {
$controllerProvider.register(name, constructor);
return (this);
};
routes.forEach(function (route) {
$routeProvider.when(route.url, route.config);
});
}]);
var controllerId = 'Index';
app.controller(controllerId, function ($scope, $location) {
var ind = this;
$scope.openDashboard = function () {
$location.path('/');

$scope.openOpportunity = function () {

I have created three separate aspx pages for each menu and separate .js file (in which controller is defined for each page).
When the page load, it calls dashboard page by default and it throws error as
Error: [ng:areq]
http://errors.angularjs.org/1.3.0-beta.17/ng/areq?p0=dashboardController&p1=not%20a%20function%2C%20got%20undefined
Here, dashboardController is the name of the controller defined in Dashboard page.
Dashboard.aspx:
<%# Page Language="C#" AutoEventWireup="true" CodeBehind="dashboard.aspx.cs" Inherits="SPA.Views.dashboard" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.25/angular.min.js"></script>
<script src="../Controllers/dashboard.js"></script>
</head>
<body>
<form id="form1" runat="server">
<div data-ng-controller="dashboardController">
{{message}}
</div>
</form>
</body>
</html>
and the associated controller file is as follows (dashboard.js):
(function () {
var app = angular.module('app');
var controllerId = 'DashboardController';
app.controller(controllerId, function ($scope) {
$scope.message = "Hello!!";
});
})();
The other pages also have the same code and that too provide the above mentioned error when a menu is selected.
When I tried to call 'dashboard.js' file in index.aspx itself, it display the page correctly.
But I don't want to call all the js file at the starting, since in future i will be using a large amount of data to display in each page and hence it might slow down the application.
Please let me know, how I should proceed to get the output by calling the controllers when that particular page is called.
Thanks in advance...

The error is pretty clear - stating dashboardController is not defined. You're attempting to call your controller DashboardController as such
<div data-ng-controller="dashboardController"> <!-- lowercase d -->
var controllerId = 'DashboardController'; // -- capital D
Forget the var and lowercase your controller name as such. Also, remove var app = angular.module('app');. You're overwriting your prior module definition, which you already have in App.js. The entire contents of dashboard.js should be the following
app.controller('dashboardController', function ($scope) {
$scope.message = 'Hello!!';
});
