How to extract data from URLs in Angular

Looking into how to extract a specific value from the URL within Angular for parsing purposes.

For example:

 http://localhost:1337/doc-home/#/tips/5?paginatePage=1

The goal is to retrieve the value "5".

HTML snippet:

<a href="#/tips/comments/{{ tip.id }}?groupid={{ ????? }}" class="btn-yellow">Add / View Comments</a>

In module.js:

 .when('/tips/comments/:group?id', {
    templateUrl: 'partials/comments.html'

Inside controller.js:

  .controller('TipCommentsCtrl',

     function ($http, $scope, $routeParams, Categories, Tip, $location, error, $sce) {

UPDATE

Making progress with the help of feedback received so far. Another related question has been posted to provide more context on the issue.

Angular routeParams not working URL is changing

Answer 1

Answer №1

Based on your needs, you have a few options to consider:

If you are utilizing ngRoute in Angular, you can incorporate $routeParams into your controller. NgRoute is part of the core Angular module and works well for simple scenarios. URL: https://docs.angularjs.org/api/ngRoute http://docs.angularjs.org/api/ngRoute/service/$routeParams

If you are using RouteProvider and routeParams: The route connects the URL to your Controller/View, and the routeParams can be passed into the controller. Take a look at the Angular seed project. In the app.js file, there's an example for the route provider. To use params, simply add them like this:
```
   $routeProvider.when('/view1/:param1/:param2', {
     templateUrl: 'partials/partial1.html',    
     controller: 'MyCtrl1'
   });
```
Then inject $routeParams in your controller:
```
   .controller('MyCtrl1', ['$scope','$routeParams', function($scope,     
   $routeParams) {
     var param1 = $routeParams.param1;
     var param2 = $routeParams.param2;
     ...
   }]);
```

You can also retrieve other arbitrary parameters from the query string format /view/1/2?other=12 with $routeParams.other.

Ui-router is a contributed module that addresses the limitations of ngRoute, especially for Nested/Complex views. If you're using angular-ui-router, you can utilize $stateParams. URL: https://github.com/angular-ui/ui-router, https://github.com/angular-ui/ui-router/wiki/URL-Routing.

For instance: http://angular-ui.github.io/ui-router/sample/#/

While your question focused on parameter retrieval, I've provided additional information on choosing the right approach and how to implement it. I hope this assists you. Thank you.
