In AngularJS it has the ability to route a section of the page using ng-view. This is really nice for smaller projects but as projects get larger it does not scale very well due to the inability to load scripts in the script tag. I've seen a few other posts that regard this but I cannot get a solution to work. The only way I can get it to work (I consider it a hack and doesn't work the way I would like it) is if I include all the scripts at the top of the base Index.html.
What I would like is when the view changes to have the Javascript files, in the header of the View being loaded, be loaded at that point since they are going to actually be used at that point and not have to pre-load them at the beginning of the application.

In the demo project the Index.html calls the console.log command but I cannot get page1 or page2 to call the log command. Any help would be greatly appreciated.
I am using Angular 1.3.0 Beta 11.
2 things, in your view you don't have to write <html> or <body> tags, you've already got those on you main page. You should see the view as a part of the main page.
second, to add javascript to your views you add a controller to the view like this:
.config(function ($routeProvider) {
$routeProvider
.when('/page1', {
templateUrl: 'page1.html',
controller: function ($log) {
$log.info('page 1');
}
})
.when('/page2', {
templateUrl: 'page2.html',
controller: function ($log) {
$log.info('page 2');
}
});
});
it's also possible to add a controller to a view like this:
var app = angular.module('routeApp', ['ngRoute'])
.config(function ($routeProvider) {
$routeProvider
.when('/page1', {
templateUrl: 'page1.html',
controller: function ($log) {
$log.info('page 1');
}
})
.when('/page2', {
templateUrl: 'page2.html',
controller: 'ViewController'
});
});
app.controller('ViewController', function ($log) {
$log.info('page 2');
})

For some reason, the second Controller isn't receiving the data from the Service.
I'm trying to make the communication between two Controllers using one Service for it.
The View:
<div class="btn-wrapper" ng-controller="FirstController">
<a ng-href="" ng-click="doPath()" id="go" class="button">GO!</a>
</div>
The FirstController.js:
angular.module('app')
.controller('FirstController', function($scope, sharedService) {
$scope.doPath = sharedService.searchPath;
});
The sharedService:
angular.module('myServices', [])
.service('sharedService', function($rootScope) {
this.searchPath = function() {
console.log("I got the service!");
$rootScope.$broadcast('Search', {
data: 'something'
});
}
});
And the SecondController.js
angular.module('app')
.controller('SecondController', function(sharedService, $scope) {
$scope.$on('Search', function(event, data){
console.log(data);
//this.search(); => I intent to run this function after this
});
});
The event is dispatched by a button in the View, that calls the doPath() function. This function does communication with the Service sharedService and the message "I got the service" is displayed.
However, the app stops here. And the communication between Service and the second Controller, using $rootScope.$broadcast, seems that not happening (the data isn't showing on console, neither any error).
I found some solutions here. I have tried already all of answers, so the problem is not the same, cause still not working.
EDIT
The ngRoute is here (app.js):
angular.module('app', ['ngRoute', 'myServices'])
.config(function($routeProvider){
$routeProvider
.when('/', {
templateUrl: 'views/main.html',
controller: 'FirstController'
})
.otherwise({
redirectTo: '/'
});
});
As everyone suggested 'Instantiation' of the Second controller is needed.
<div ng-controller="firstController">
//code
</div>
<div ng-controller="secondController">
//code
</div>
Like above.
I know you have used 'ngRoute'. Until you change your view the second controller will not be loaded in 'ngRoute' whereas in above code both the controllers are in the same view. That is why above code works and 'ngRoute' does not.
SecondController is not instantiated by Angular because you are referring only FirstController from html. You need to instantiate the SecondController on the same html using parent child or sibling relationship depending on your application.
I'm using Angular for my android application. After given time I need to open a template file. This is my app.js for the particular template file
.when('/tracker/',
{
templateUrl: 'views/tracker.html',
controller: 'MainController'
})
I want to open this tracker.html file directly from my MainController and I'm not sure how to do that. If you need more information let me know.
Since I'm still new to Angular any help would be appreciated to make this happen.
You can try linking one of your scope attributes to a modal (this would open your tracker.html as a popup and then you can define other stuffs)
function MainController($scope, $uibModal) {
var modalInstance;
$scope.open= function () {
modalInstance = $uibModal.open({
templateUrl: 'views/tracker.html',
controller: 'MainController'
});
};
}
What you've done seems sufficient, I'll explain your code snippet.
.when('/tracker/',...
The above snippet says, when a user or browser requests the URL yourhost.com/tracker/', do what's following,
.., {
templateUrl: 'views/tracker.html',
controller: 'MainController'
})
Direct them to the template views/tracker.html and use the controller MainController on the specified template above.
That's the simplest explanation i could come up with. I hope navigating your browser to the link, yourhost.com/tracker/ will show you the tracker.html template you need.
If the above fails, make sure you have correctly defined your ng-view directives in your index.html file (https://docs.angularjs.org/api/ngRoute/directive/ngView) or watch out the browser console for any errors.
Of course, I should mention that I'm new to this thing, so sorry if this is something trivial.
So I pretty much have 2 routes (views). localhost:3000 takes in and loads up a list of objects and localhost:3000/:slug shows information of the product the users wants to see more info about.
The initial listing is fine. You visit localhost:3000 and you see a list of items.
listPhoneController.js:
angular.module('cmscApp').controller('listPhoneController', ['$scope', '$http', '$location', 'searchBoxFactory',
function($scope, $http, $location, searchBoxFactory) {
$scope.listInfo = searchBoxFactory;
$scope.phoneList = [];
$http.get('/api/getallphones').then(function(res) {
$scope.phoneList = res.data;
}, function() {
$scope.errorMsg = 'Error in reaching data';
});
}]);
list.html:
<!-- ... --->
<div class="result" ng-repeat="phone in phoneList | hasImageFilter:listInfo.imageRequired
| nameFilter:listInfo.phoneName
| priceFilter:listInfo.price.from:listInfo.price.to">
<!-- filters don't seam to be the problem (removing them still causes the issue) -->
<a ng-href="/phone.slug">More info...</a>
<!-- ... -->
</div>
Now, if I click on the a tag, I get redirected to that phone's information view (ie. localhost:3000/samsung-galaxy-s4) and information is being loaded correctly. I also have a back button there, with a simple <a ng-href='/'>Back</a>
But, when I go back, even though the URL changes back to localhost:3000, the list doesn't appear. I get no errors, nothing, but the div's aren't there (when inspecting, nor anything).
Is this because $http is async, so it tries to load the page before it gets the info? If that's the case, why doesn't it just bind the data, as usual?
Here's my config:
angular.module('cmscApp').config(function ($routeProvider, $locationProvider) {
$routeProvider
.when('/', {
templateUrl: '/pages/list.html',
controller: 'listPhoneController',
controllerAs: 'lpc'
})
.when('/:phoneSlug', {
templateUrl: '/pages/detail.html',
controller: 'detailPhoneController',
controllerAs: 'dpc'
})
.otherwise({
templateUrl: '/error/404.html'
});
$locationProvider.html5Mode({
enabled: true,
requireBase: false
});
});
Any sort of help is more than welcome!! I thought about storing the data from $http to a factory, so then it loads that data every time the controller is run, while updating it as well. would that be a viable solution, or is there something better?
Turns out the scope didn't bind for some reason, so I had to edit the $http.get().then() method:
$http.get(...).then(function(res) {
$scope.data = res;
$scope.$apply();
}, function() { ... });
for anyone encountering a similar issue
I'm new to Angular.js which is why I have a basic question regarding routing. I figured out how to create routes and inject specific .htmls by $routeProvider
var app = angular.module('test', ['ngRoute']);
app.config(function($routeProvider) {
$routeProvider
.when('/', {
templateUrl: 'routes/view2.html'
});
});
but what I really don't get is how content or function of view2.html are handled in Angular.
Lets take view2.html. It has a <p> with some text in a specific color. Nothing to special. But also it has a little slideshow which is called by $('slideshow').cycle() function.
All what happens is it displays me the <p> tag in a different color and no slideshow function is called on my rootsite of the app.
Could you give me some approach how to actually solve this?
Thanks
Just load required view and then compile it. During compilation Angular processes all directives in view.
If you want to do this proper(Angular) way you should put such code like $('slideshow').cycle() inside of directive. And then use it like
<div my-slideshow=""></div>
angular.module('myModule', [])
.directive('mySlideshow', [function () {
return {
restrict: 'A',
link: function (scope, element) {
element.cycle();
}
}
}]);

Here's the [plunker]:http://plnkr.co/edit/iPsyEAIQWxJIJuneZb8B?p=preview
What I want is when I click login, the auth directive should change template to 'logout.html' automatically , and then when logout clicked, switch to use 'login.html'.
But so far, I should refresh page manully to make directive to switch template.
How can I achieve this purpose?
Using routes.
app.config(['$routeProvider', function ($routeProvider) {
$routeProvider
.when('/login', {
templateUrl: 'login.html',
controller: 'loginCtrl'
})
.when('/logout', {
templateUrl: 'logout.html',
controller: 'logoutCtrl'
})
}]);
Then you do $location.path('/logout') or $location.path('/login')

I've fixed a couple of bugs in your plunker. Check it out here
Your major error was the $watch expression. It should be scope.$watch('authed', function () {}); not scope.$watch(scope.authed, function () {});.
I've also played a bit with it and came up with this version. The idea is to separate logon/logout logic with cookie manipulation and get rid of explicit DOM manipulation, $compile() etc.
