Angularjs - How to send and retrieve parameters using $state.go toParams and $stateParams?

In AngularJS, when you want to send parameters using $state.go and retrieve them using $stateParams, you typically use the following approach:

Sending Parameters with $state.go

To send parameters to a state using $state.go, you pass an object containing the parameters as the second argument. For example:

$state.go('stateName', { param1: 'value1', param2: 'value2' });

Here:

  • 'stateName' is the name of the state you want to navigate to.
  • { param1: 'value1', param2: 'value2' } is an object containing parameters and their corresponding values.

Retrieving Parameters with $stateParams

To retrieve parameters sent via $state.go, you use $stateParams in the destination controller or component. First, ensure you have injected $stateParams into your controller or component:

app.controller('MyController', ['$scope', '$stateParams', function($scope, $stateParams) { // Access parameters from $stateParams $scope.param1 = $stateParams.param1; $scope.param2 = $stateParams.param2; }]);

Here:

  • $stateParams is injected into the controller or component.
  • param1 and param2 are accessed directly from $stateParams.

Example

Let's say you want to navigate to a state named userDetails with parameters userId and userName, and then retrieve these parameters in the UserDetailsController:

Sending Parameters

// Navigating to state with parameters $state.go('userDetails', { userId: 123, userName: 'John Doe' });

Retrieving Parameters

// Define the state configuration app.config(['$stateProvider', function($stateProvider) { $stateProvider.state('userDetails', { url: '/user/:userId', templateUrl: 'user-details.html', controller: 'UserDetailsController' }); }]); // UserDetailsController to retrieve parameters app.controller('UserDetailsController', ['$scope', '$stateParams', function($scope, $stateParams) { // Access parameters from $stateParams $scope.userId = $stateParams.userId; $scope.userName = $stateParams.userName; }]);

Explanation

  • Sending Parameters: Use $state.go with the state name (userDetails) and an object containing parameters ({ userId: 123, userName: 'John Doe' }).
  • Retrieving Parameters: In the UserDetailsController, inject $stateParams and access parameters directly ($stateParams.userId and $stateParams.userName).

Notes

  • Ensure that the parameter names (userId, userName) match between the state definition (url: '/user/:userId') and how they are passed ({ userId: 123, userName: 'John Doe' }) to $state.go.
  • AngularJS will automatically populate $stateParams with parameters extracted from the URL or those passed directly via $state.go.

This approach allows you to effectively send parameters using $state.go and retrieve them using $stateParams in your AngularJS application.

Examples

  1. AngularJS $state.go with parameters example

    • Description: Learn how to use $state.go to navigate between states and pass parameters in AngularJS.
    • Code:
      // Sending parameters $state.go('stateName', { param1: 'value1', param2: 'value2' }); // Retrieving parameters app.controller('ControllerName', function($stateParams) { console.log($stateParams.param1); // Output: 'value1' console.log($stateParams.param2); // Output: 'value2' });

    • Description: Use $state.go to send parameters and access them using $stateParams in AngularJS.
    • Code:
      // Sending parameters $state.go('stateName', { paramA: 'dataA', paramB: 'dataB' }); // Retrieving parameters app.controller('ControllerName', function($stateParams) { console.log($stateParams.paramA); // Output: 'dataA' console.log($stateParams.paramB); // Output: 'dataB' });

  5. AngularJS $state.go pass and retrieve parameters

    • Description: Pass parameters with $state.go and retrieve them using $stateParams in AngularJS.
    • Code:
      // Sending parameters $state.go('stateName', { userId: 456, userName: 'Jane Doe' }); // Retrieving parameters app.controller('ControllerName', function($stateParams) { console.log($stateParams.userId); // Output: 456 console.log($stateParams.userName); // Output: 'Jane Doe' });

  6. Passing parameters with $state.go in AngularJS and using $stateParams

    • Description: Send parameters using $state.go and utilize $stateParams to retrieve them in AngularJS.
    • Code:
      // Sending parameters $state.go('stateName', { paramX: 'valueX', paramY: 'valueY' }); // Retrieving parameters app.controller('ControllerName', function($stateParams) { console.log($stateParams.paramX); // Output: 'valueX' console.log($stateParams.paramY); // Output: 'valueY' });

  7. AngularJS $state.go pass and retrieve URL parameters

    • Description: Pass and retrieve URL parameters using $state.go and $stateParams in AngularJS.
    • Code:
      // Sending parameters $state.go('stateName', { key1: 'data1', key2: 'data2' }); // Retrieving parameters app.controller('ControllerName', function($stateParams) { console.log($stateParams.key1); // Output: 'data1' console.log($stateParams.key2); // Output: 'data2' });

  8. Sending parameters in $state.go and accessing them with $stateParams in AngularJS

    • Description: Use $state.go to send parameters and $stateParams to access them effectively in AngularJS.
    • Code:
      // Sending parameters $state.go('stateName', { param1: 'value1', param2: 'value2' }); // Retrieving parameters app.controller('ControllerName', function($stateParams) { console.log($stateParams.param1); // Output: 'value1' console.log($stateParams.param2); // Output: 'value2' });

  9. AngularJS navigate to state with parameters using $state.go and $stateParams
