AngularJs routing involves handling server requests efficiently. Here are some common questions related to this topic

On my current webpage, the code looks like this:

<!doctype html>
<html lang="en" ng-app="myModule">
<head>
    <meta charset="utf-8">
    <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.min.js"></script>
    <script>

        var myModule = angular.module('somename', []);

          myModule.config(function ($routeProvider) {
            $routeProvider.
                    when('/zzz', {templateUrl:'' , controller: TestCtrl}).
                    when('/test1', {template:' ', controller: TestDataCtrl}).
                    when('/test2', {template:'/abc ', controller: function TestCtrl1() {alert("test2")} }).
                    when('/test/:userid', { controller: TestDataCtrl }).
                    when('/users/:userid', {templateUrl: '/users/:userid?html=true', controller: UserDataCtrl}).
                    otherwise({redirectTo: '/works'});

        });

        function TestCtrl($scope) { alert("test") }

        function UserDataCtrl($scope, $http) {
    ...
        }

        function TestDataCtrl($scope, $http, $routeParams, $route) {
          $http.get('users/1').success(function (data) {
            console.log("UserDataCtrl");
            $scope.user = data;
        });

        }

    </script>
</head>
<body ng-app="myModule">
<div ng-view></div>

{{1+1}}
</body>
</html>

1) Whenever I visit the url

http://localhost:7000/service/1#/test1
, the browser makes two requests to the server - one to http://localhost:7000/service/1 and another to
http://localhost:7000/archivarius/users/1
. Is there a way to handle the first unnecessary request using an AngularJS controller? I want only the actions in the test2 controller to occur when the user enters the url
http://localhost:7000/service/1#/test1
. Is this possible?

2) In the routing configuration, why am I required to specify either a template or templateUrl? Why can't I just specify a controller for each route instead?

Answer №1

It is essential to always trace a code that is syntactically correct. In this particular scenario, there are a few key issues:

  1. The name provided for the ng-app directive is incorrect (line 2: it should be ng-app="someoname" because your module's name is "somename")
  2. Your application is being initialized multiple times: - There is an ng-app on line 2 (
    <html lang="en" ng-app="myModule">
    ) and another one on your body tag (<body ng-app="myModule">)

Addressing these syntax errors will allow you to then analyze your app's logical flow effectively.

Answer №2

There may be two HTTP requests visible due to using $http.get('users/1') and the templateUrl in the '/users/:userid' route.

When configuring routing, make sure to specify either a template or templateUrl along with a controller for each route.
