AngularJS Routing using ngRoute Route parameters example
Example
This example extends the basic example passing parameters in the route in order to use them in the controller
To do so we need to:
- Configure the parameter position and name in the route name
- Inject
$routeParamsservice in our Controller
app.js
angular.module('myApp', ['ngRoute'])
.controller('controllerOne', function() {
this.message = 'Hello world from Controller One!';
})
.controller('controllerTwo', function() {
this.message = 'Hello world from Controller Two!';
})
.controller('controllerThree', ['$routeParams', function($routeParams) {
var routeParam = $routeParams.paramName
if ($routeParams.message) {
// If a param called 'message' exists, we show it's value as the message
this.message = $routeParams.message;
} else {
// If it doesn't exist, we show a default message
this.message = 'Hello world from Controller Three!';
}
}])
.config(function($routeProvider) {
$routeProvider
.when('/one', {
templateUrl: 'view-one.html',
controller: 'controllerOne',
controllerAs: 'ctrlOne'
})
.when('/two', {
templateUrl: 'view-two.html',
controller: 'controllerTwo',
controllerAs: 'ctrlTwo'
})
.when('/three', {
templateUrl: 'view-three.html',
controller: 'controllerThree',
controllerAs: 'ctrlThree'
})
.when('/three/:message', { // We will pass a param called 'message' with this route
templateUrl: 'view-three.html',
controller: 'controllerThree',
controllerAs: 'ctrlThree'
})
// redirect to here if no other routes match
.otherwise({
redirectTo: '/one'
});
});
Then, withoud making any changes in our templates, only adding a new link with custom message, we can see the new custom message in our view.
index.html
<div ng-app="myApp">
<nav>
<!-- links to switch routes -->
