How to pass parameters using ui-sref in ui-router to the controller

📝 Tech Blog: Passing Parameters using ui-sref in ui-router to the Controller

Hey there, tech enthusiasts! 👋 Today we are here to tackle a common question that often leaves developers scratching their heads: "How can I pass parameters using ui-sref in ui-router to the controller?" We'll dig deep into this issue, provide easy solutions, and empower you to navigate this challenge with ease. Let's get started! 💪

To set the stage, imagine you have a link that needs to transition from one state to another while passing some parameters to the destination state. Here's an example that demonstrates how you can achieve this using the ui-sref attribute:

<a ui-sref="home({foo: 'fooVal', bar: 'barVal'})">Go to home state with foo and bar parameters</a>

In the above code snippet, we're specifying the state to transition to as "home" and passing the foo and bar parameters with values "fooVal" and "barVal", respectively.

Now, let's talk about how to receive these parameters in your controller. In AngularJS, you can access them via the $stateParams service. However, in your provided code, you encountered an issue of getting undefined for $stateParam in the controller.

The reason behind this error is most likely due to a typo. The correct service name is $stateParams, plural, not $stateParam. 🙃

Here's an updated code snippet of your controller, with the corrected service name:

app.controller('SomeController', function($scope, $stateParams) {
  // ..
  var foo = $stateParams.foo; // Now you'll get the value "fooVal"
  var bar = $stateParams.bar; // Now you'll get the value "barVal"
  // ..
});

Now you're all set! By accessing $stateParams.foo and $stateParams.bar in your controller, you'll be able to retrieve the values passed as parameters using ui-sref.

In case you're wondering, your ui-router configuration hasn't been provided, but to give you an idea, here's a sample snippet:

.state('home', {
  url: '/',
  views: {
    '': {
      templateUrl: 'home.html',
      controller: 'MainRootCtrl'
    },
    'A@home': {
      templateUrl: 'a.html',
      controller: 'MainCtrl'
    },
    'B@home': {
      templateUrl: 'b.html',
      controller: 'SomeController'
    }
  }
});

Feel free to adapt this to fit your project structure! 😉
