AngularJS - How to use $routeParams in generating the templateUrl?
(8 answers)
Closed 3 years ago.
I am building an angularjs app, my app.js looks like this. However, it throws Unknown provider: $routeParams error. Any idea why?
var angularSite = angular.module('angularSite', [
'ui.router',
'ngRoute',
'siteController',
'siteDirectives'
])
.config(['$routeProvider', '$routeParams',
function($routeProvider,$routeParams) {
$routeProvider.
when('/Projects', {
templateUrl: 'partials/projects.html',
controller: 'ProjectController'
}).
when('/Projects/:projectId', {
template: 'partials/pages/'+$routeParams.projectId+'.html',
controller: 'ProjectDetailController'
}).
otherwise({
redirectTo: '/About'
});
}]);

$routeParams is a service and can not be injected in .config.
If you want to set your templateUrl from URL params, the correct way is to use a function to set the templateUrl (as following):
.when('/Projects/:projectId', {
templateUrl: function(params) { // <--
return 'partials/pages/' + params.projectId + '.html'
},
controller: 'ProjectDetailController'
})

Available in AngularJS 1.2 access route params at a configuration level replace.
template: 'partials/pages/'+$routeParams.projectId+'.html',
with:
templateUrl: function(params){ return 'partials/pages/' + params.projectId + 'html'; }
source - AngularJS - How to use $routeParams in generating the templateUrl?

In the config of an Angular module is not allowed to use services. $routeParams is a Service so you can not use it there.
I would recommend you to include one template or another through your controller ProjectDetailController.
In this controller you can inject and use the service $routeParams, in order to choose one template or another. Something like:
So, your config:
when('/Projects/:projectId', {
template: 'partials/pages/main.html',
controller: 'ProjectDetailController'
}).
Your controller:
Controller.$inject = ['$routeParams'];
/* #ngInject */
function Controller($routeParams) {
var vm = this;
vm.template = 'partials/pages/'+$routeParams.projectId+'.html';
}
And your main.html template:
<ng-include src="vm.template"/>

Loading modules in Angularjs

I have a problem trying to load some modules.
controller1.js:
angular.module('LPC')
.controller('lista_peliculas_controller', ['$scope', function($scope) {
$scope.hola="hola peliculas";
}]);
And app.js:
var app = angular.module('mis_peliculas', []);
app.config(function($routeProvider){
$routeProvider
.when("/pagina_principal",{
templateUrl: "views/pagina_principal.html",
controller: "lista_peliculas_controller"
})
.when("/lista_peliculas",{
templateUrl: "views/lista_peliculas.html",
controller: "lista_peliculas_controller"
})
.when("/lista_series",{
templateUrl: "views/lista_series.html",
controller: "lista_series_controller"
})
.otherwise({
redirectTo: "/pagina_principal"
})
});
The console says that there is a problem with the injector.
Can you find the error?
You must add angular-route.js . Reference
The ngRoute module provides routing and deeplinking services and
directives for AngularJS apps.
How do you fix it?
var app = angular.module('mis_peliculas', ['ngRoute','LPC']);
And
angular.module('LPC', [])
Update your code to use right module name:
angular.module('mis_peliculas')
.controller('lista_peliculas_controller', ['$scope', function($scope) {
$scope.hola="hola peliculas";
}]);
and if you want to use separate modules, you need to initiliaze it first and inject it into your main module
angular.module('LPC',[])
.controller('lista_peliculas_controller', ['$scope', function($scope) {
$scope.hola="hola peliculas";
}]);
var app = angular.module('mis_peliculas', ['LPC']);
I assume your routing is already set correctly.
without the complete log of the error i can't be more precise, but i think that the injection error could be related to your module not being instantiated.
try to change
angular.module('LPC') //here you get a reference to a module, that could cause your error
to
angular.module('LPC', []) //here you instantiate a module
You need to pass in the 'LPC' Module to your app 'mis_peliculas' module for it use the 'lista_peliculas_controller' Controller which is in 'LPC' Module.
Try this code
angular.module('LPC',[])
.controller('lista_peliculas_controller', ['$scope', function($scope) {
$scope.hola="hola peliculas";
}]);
This should be your controller1.js and should be defined before you define your app. Now the app.js should look like
var app = angular.module('mis_peliculas', ['LPC']);
app.config(function($routeProvider){
$routeProvider
.when("/pagina_principal",{
templateUrl: "views/pagina_principal.html",
controller: "lista_peliculas_controller"
})
.when("/lista_peliculas",{
templateUrl: "views/lista_peliculas.html",
controller: "lista_peliculas_controller"
})
.when("/lista_series",{
templateUrl: "views/lista_series.html",
controller: "lista_series_controller"
})
.otherwise({
redirectTo: "/pagina_principal"
})
});
This should remove all the errors and you should be able to use the controller from other module.
Hope it helps

pass a variable into $routeProvider in angular between views? - angularjs

Wondering if there's an 'angular specific' way to try and achieve this.
I have a page with some views. When a user clicks an anchor, the views change, simple enough. What I'm curious is, if when the user clicks, is it possible to store a variable (say the span) then pass it to the $routeProvider to load the content a bit more dynamically?
so for anchor tag #name1, when that view is displayed, I can pass "name1" into nameHolder as a variable to load some files with same name.
HTML
<span>name1</span>
JS
var nameHolder = [];
var sampleApp = angular.module('sampleApp', ['ngRoute']);
sampleApp.config(['$routeProvider',
function($routeProvider) {
$routeProvider.
when('/' + nameHolder, {
templateUrl: 'templates/individkcd.html',
controller: 'individ',
nameofuser: nameHolder
}).
when('/', {
templateUrl: 'templates/home.html'
});
}]);
sampleApp.controller('individ', function($scope, $route) {
$scope.img = $route.current.nameHolder;
});
Thanks for any info.
UPDATED:
Solution at new thread.
angular js - passing a variable into $routeProvider
You need to add the parameter to your $routeProvider template:
sampleApp.config(['$routeProvider',
function($routeProvider) {
$routeProvider.
when('/' + nameHolder, {
templateUrl: 'templates/individkcd/:nameHolder',
controller: 'individ'
}).
when('/', {
templateUrl: 'templates/home.html'
});
}]);
Then in your target controller use $routeParams:
sampleApp.controller('individ', function($scope, $routeParams) {
$scope.img = $routeParams.nameHolder;
});
From the $routeProvider docs linked above:
path can contain named groups starting with a colon: e.g. :name. All
characters up to the next slash are matched and stored in $routeParams
under the given name when the route matches

Set variable in Angular per template

I need to update a variable on a per template basis.
My main index file (the layout file) displays this value. I can use ng-init, but that only works if I call ng-init before the expression.
If I use ng-init on the template pages, it does not work (I suspect due to code order).
ng-ignit
<div ng-init="amount='4'"></div>
Index.html (layout file)
<span class="amount">{{amount}}</span>
Main_controller.js
$scope.amount = 1; //default value
How can I have multiple templates with different values of the amount variable?
There are so many ways of achieving what you desire. But the most relevant way to what you're looking for is using a resolve.
Use a resolve in your routeProvider
var sampleApp = angular.module('phonecatApp', []);
sampleApp.config(['$routeProvider',
function($routeProvider) {
$routeProvider.
when('/page1', {
templateUrl: 'templates/page1.html',
controller: 'myController',
resolve: {
data: 1
}
}).
when('/showOrders', {
templateUrl: 'templates/page2.html',
controller: 'ShowOrdersController',
resolve: {
data: 2
}
}).
otherwise({
redirectTo: '/page1'
});
}]);
In your controller
sampleApp.controller('myController', function($scope, data){
$scope.amount = data;
})

Angularjs Routing in Windws 8 Store Apps

I am new to windows store app development. Any how manage to get worked angularjs inside Windows 8 store app by editing angular js library. But Could not understand how to use angulerjs routing inside store app.
Can anyone explain how to use angular js routing in side Windows Store app or give an example to how to do that.
I'm building a universal app and I'm using angularjs.
It is my app.js
var app = angular.module('app', ['ngRoute']);
app.config(['$routeProvider', function ($routeProvider) {
$routeProvider.
when('/', {
templateUrl: '/views/default.html',
controller: 'default'
}).
when('/customers', {
templateUrl: '/views/customers.html',
controller: 'customers'
}).
when('/products/:param', {
templateUrl: '/views/products.html',
controller: 'products'
}).
otherwise({
redirectTo: '/'
});
}]);
I have the below code for opening customers screen.
$scope.openCustomers = function () {
$location.path('/customers');
}
I have the below code for opening products screen.
$scope.openProducts = function () {
$location.path('/products/123');
}
It is my customers controller code
app.controller('customers', ['$scope', function ($scope) {
});
It is my products controller code
app.controller('products', ['$scope', '$routeParams', function ($scope,$routeParams) {
$scope.param= $routeParams.param;
});

AngularJS dynamic routing

I currently have an AngularJS application with routing built in.
It works and everything is ok.
My app.js file looks like this:
angular.module('myapp', ['myapp.filters', 'myapp.services', 'myapp.directives']).
config(['$routeProvider', function ($routeProvider) {
$routeProvider.when('/', { templateUrl: '/pages/home.html', controller: HomeController });
$routeProvider.when('/about', { templateUrl: '/pages/about.html', controller: AboutController });
$routeProvider.when('/privacy', { templateUrl: '/pages/privacy.html', controller: AboutController });
$routeProvider.when('/terms', { templateUrl: '/pages/terms.html', controller: AboutController });
$routeProvider.otherwise({ redirectTo: '/' });
}]);
My app has a CMS built in where you can copy and add new html files within the /pages directory.
I would like to still go through the routing provider though even for the new dynamically added files.
In an ideal world the routing pattern would be:
$routeProvider.when('/pagename', { templateUrl: '/pages/pagename.html', controller: CMSController });
So if my new page name was "contact.html" I would like angular to pick up "/contact" and redirect to "/pages/contact.html".
Is this even possible?! and if so how?!
Update
I now have this in my routing config:
$routeProvider.when('/page/:name', { templateUrl: '/pages/home.html', controller: CMSController })
and in my CMSController:
function CMSController($scope, $route, $routeParams) {
$route.current.templateUrl = '/pages/' + $routeParams.name + ".html";
alert($route.current.templateUrl);
}
CMSController.$inject = ['$scope', '$route', '$routeParams'];
This sets the current templateUrl to the right value.
However I would now like to change the ng-view with the new templateUrl value. How is this accomplished?
angular.module('myapp', ['myapp.filters', 'myapp.services', 'myapp.directives']).
config(['$routeProvider', function($routeProvider) {
$routeProvider.when('/page/:name*', {
templateUrl: function(urlattr){
return '/pages/' + urlattr.name + '.html';
},
controller: 'CMSController'
});
}
]);
Adding * let you work with multiple levels of directories dynamically.
Example: /page/cars/selling/list will be catch on this provider
From the docs (1.3.0):
"If templateUrl is a function, it will be called with the following
parameters:
{Array.} - route parameters extracted from the current
$location.path() by applying the current route"
Also
when(path, route) : Method
path can contain named groups starting with a colon and ending with a star: e.g.:name*. All characters are eagerly stored in $routeParams under the given name when the route matches.
Ok solved it.
Added the solution to GitHub - http://gregorypratt.github.com/AngularDynamicRouting
In my app.js routing config:
$routeProvider.when('/pages/:name', {
templateUrl: '/pages/home.html',
controller: CMSController
});
Then in my CMS controller:
function CMSController($scope, $route, $routeParams) {
$route.current.templateUrl = '/pages/' + $routeParams.name + ".html";
$.get($route.current.templateUrl, function (data) {
$scope.$apply(function () {
$('#views').html($compile(data)($scope));
});
});
...
}
CMSController.$inject = ['$scope', '$route', '$routeParams'];
With #views being my <div id="views" ng-view></div>
So now it works with standard routing and dynamic routing.
To test it I copied about.html called it portfolio.html, changed some of it's contents and entered /#/pages/portfolio into my browser and hey presto portfolio.html was displayed....
Updated
Added $apply and $compile to the html so that dynamic content can be injected.
I think the easiest way to do such thing is to resolve the routes later, you could ask the routes via json, for example. Check out that I make a factory out of the $routeProvider during config phase, via $provide, so I can keep using the $routeProvider object in the run phase, and even in controllers.
'use strict';
angular.module('myapp', []).config(function($provide, $routeProvider) {
$provide.factory('$routeProvider', function () {
return $routeProvider;
});
}).run(function($routeProvider, $http) {
$routeProvider.when('/', {
templateUrl: 'views/main.html',
controller: 'MainCtrl'
}).otherwise({
redirectTo: '/'
});
$http.get('/dynamic-routes.json').success(function(data) {
$routeProvider.when('/', {
templateUrl: 'views/main.html',
controller: 'MainCtrl'
});
// you might need to call $route.reload() if the route changed
$route.reload();
});
});
In the $routeProvider URI patters, you can specify variable parameters, like so: $routeProvider.when('/page/:pageNumber' ... , and access it in your controller via $routeParams.
There is a good example at the end of the $route page: http://docs.angularjs.org/api/ng.$route
EDIT (for the edited question):
The routing system is unfortunately very limited - there is a lot of discussion on this topic, and some solutions have been proposed, namely via creating multiple named views, etc.. But right now, the ngView directive serves only ONE view per route, on a one-to-one basis. You can go about this in multiple ways - the simpler one would be to use the view's template as a loader, with a <ng-include src="myTemplateUrl"></ng-include> tag in it ($scope.myTemplateUrl would be created in the controller).
I use a more complex (but cleaner, for larger and more complicated problems) solution, basically skipping the $route service altogether, that is detailed here:
http://www.bennadel.com/blog/2420-Mapping-AngularJS-Routes-Onto-URL-Parameters-And-Client-Side-Events.htm
Not sure why this works but dynamic (or wildcard if you prefer) routes are possible in angular 1.2.0-rc.2...
http://code.angularjs.org/1.2.0-rc.2/angular.min.js
http://code.angularjs.org/1.2.0-rc.2/angular-route.min.js
angular.module('yadda', [
'ngRoute'
]).
config(function ($routeProvider, $locationProvider) {
$routeProvider.
when('/:a', {
template: '<div ng-include="templateUrl">Loading...</div>',
controller: 'DynamicController'
}).
controller('DynamicController', function ($scope, $routeParams) {
console.log($routeParams);
$scope.templateUrl = 'partials/' + $routeParams.a;
}).
example.com/foo -> loads "foo" partial
example.com/bar-> loads "bar" partial
No need for any adjustments in the ng-view. The '/:a' case is the only variable I have found that will acheive this.. '/:foo' does not work unless your partials are all foo1, foo2, etc... '/:a' works with any partial name.
All values fire the dynamic controller - so there is no "otherwise" but, I think it is what you're looking for in a dynamic or wildcard routing scenario..
As of AngularJS 1.1.3, you can now do exactly what you want using the new catch-all parameter.
https://github.com/angular/angular.js/commit/7eafbb98c64c0dc079d7d3ec589f1270b7f6fea5
From the commit:
This allows routeProvider to accept parameters that matches
substrings even when they contain slashes if they are prefixed
with an asterisk instead of a colon.
For example, routes like edit/color/:color/largecode/*largecode
will match with something like this
http://appdomain.com/edit/color/brown/largecode/code/with/slashs.
I have tested it out myself (using 1.1.5) and it works great. Just keep in mind that each new URL will reload your controller, so to keep any kind of state, you may need to use a custom service.
Here is another solution that works good.
(function() {
'use strict';
angular.module('cms').config(route);
route.$inject = ['$routeProvider'];
function route($routeProvider) {
$routeProvider
.when('/:section', {
templateUrl: buildPath
})
.when('/:section/:page', {
templateUrl: buildPath
})
.when('/:section/:page/:task', {
templateUrl: buildPath
});
}
function buildPath(path) {
var layout = 'layout';
angular.forEach(path, function(value) {
value = value.charAt(0).toUpperCase() + value.substring(1);
layout += value;
});
layout += '.tpl';
return 'client/app/layouts/' + layout;
}
})();
