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

Question

If you want to pass non-URL state, then you must not use url when setting up your state. I found the answer on a PR and did some monkeying around to better understand.

$stateProvider.state('toState', {
  templateUrl:'wokka.html',
  controller:'stateController',
  params: {
    'referer': 'some default', 
    'param2': 'some default', 
    'etc': 'some default'
  }
});

Then you can navigate to it like so:

$state.go('toState', { 'referer':'jimbob', 'param2':37, 'etc':'bluebell' });

Or:

var result = { referer:'jimbob', param2:37, etc:'bluebell' };
$state.go('toState', result);

And in HTML thusly:

<a ui-sref="toState(thingy)" class="list-group-item" ng-repeat="thingy in thingies">{{ thingy.referer }}</a>

This use case is completely uncovered in the documentation, but I think it's a powerful means on transitioning state without using URLs.

The Nathan Matthews's solution did not work for me but it is totally correct but there is little point to reaching a workaround:

The key point is: Type of defined parameters and toParamas of $state.go should be same array or object on both sides of state transition.

For example when you define a params in a state as follows you means params is array because of using "[]":

$stateProvider
.state('home', {
    templateUrl: 'home',
    controller:  'homeController'
})
.state('view', {
    templateUrl: 'overview',
    params:      ['index', 'anotherKey'],
    controller:  'overviewController'
})

So also you should pass toParams as array like this:

params = { 'index': 123, 'anotherKey': 'This is a test' }
paramsArr = (val for key, val of params)
$state.go('view', paramsArr)

And you can access them via $stateParams as array like this:

app.controller('overviewController', function($scope, $stateParams) {
    var index = $stateParams[0];
    var anotherKey = $stateParams[1];
});

Better solution is using object instead of array in both sides:

$stateProvider
.state('home', {
    templateUrl: 'home',
    controller:  'homeController'
})
.state('view', {
    templateUrl: 'overview',
    params:      {'index': null, 'anotherKey': null},
    controller:  'overviewController'
})

I replaced [] with {} in params definition. For passing toParams to $state.go also you should using object instead of array:

$state.go('view', { 'index': 123, 'anotherKey': 'This is a test' })

then you can access them via $stateParams easily:

app.controller('overviewController', function($scope, $stateParams) {
    var index = $stateParams.index;
    var anotherKey = $stateParams.anotherKey;
});

All I had to do was add a parameter to the url state definition like so

url: '/toState?referer'

Doh!

Not sure if it will work with AngularJS v1.2.0-rc.2 with ui-router v0.2.0. I have tested this solution on AngularJS v1.3.14 with ui-router v0.2.13.

I just realize that is not necessary to pass the parameter in the URL as gwhn recommends.

Just add your parameters with a default value on your state definition. Your state can still have an Url value.

$stateProvider.state('state1', {
    url : '/url',
    templateUrl : "new.html",
    controller : 'TestController',
    params: {new_param: null}
});

and add the param to $state.go()

$state.go('state1',{new_param: "Going places!"});

None of these examples on this page worked for me. This is what I used and it worked well. Some solutions said you cannot combine url with $state.go() but this is not true. The awkward thing is you must define the params for the url and also list the params. Both must be present. Tested on Angular 1.4.8 and UI Router 0.2.15.

In the state add your params to end of state and define the params:

url: 'view?index&anotherKey',
params: {'index': null, 'anotherKey': null}

In your controller your go statement will look like this:

$state.go('view', { 'index': 123, 'anotherKey': 'This is a test' });

Then to pull the params out and use them in your new state's controller (don't forget to pass in $stateParams to your controller function):

var index = $stateParams.index;
var anotherKey = $stateParams.anotherKey;
console.log(anotherKey); //it works!

In my case I tried with all the options given here, but no one was working properly (angular 1.3.13, ionic 1.0.0, angular-ui-router 0.2.13). The solution was:

.state('tab.friends', {
      url: '/friends/:param1/:param2',
      views: {
        'tab-friends': {
          templateUrl: 'templates/tab-friends.html',
          controller: 'FriendsCtrl'
        }
      }
    })

and in the state.go:

$state.go('tab.friends', {param1 : val1, param2 : val2});
