Having trouble with changing the state within an AngularJS (Ionic Framework) controller?

My goal is to switch views within the Search controller after receiving search results from the server through $http. However, my current approach doesn't seem to be working as intended. I also need to pass the response to the new view for displaying the results properly.

In my app.js:

.....state('tab.search', {
  url: '/search',
  views: {
      'tab-search': {
          templateUrl: 'templates/tab-search.html',
          controller: 'SearchCtrl as search'
      }
  }
})
.state('tab.search-results', {
  url: '/results',
  views: {
      'tab-search-results': {
          templateUrl: 'templates/tab-search-results.html',
          controller: 'SearchResultsCtrl as searchResults'
      }
  }
})

My Search controller contains:

.controller('SearchCtrl', function($scope, $state, $location, $ionicPopup, service) {
....
 $scope.doSearch = function(state) {
    .....
    var result  = service.doSearch(dataObj);
    result.then(function(response) {
        console.log("I'm here");
        $state.go('tab.search-results');
        ......

The basic structure of my search results view (tab-search-results.html) looks like this:

<ion-view view-title="Search Results">
    <ion-content padding="true">
        hello world
     </ion-content>
</ion-view>

This setup is similar to my other pages/views as well.

Upon performing a search, the console message appears and the URL changes to /results according to the tab.search-results state, however, the template/view does not change or display.

If I modify $state.go('tab.search-results'); to target another app state/view that works, it functions correctly. It seems that there is an issue with this specific state/view.

If there is a more effective way to achieve the same outcome or if you have any suggestions on how to pass the "response" from SearchCtrl to SearchResultsCtrl, please advise. Any help is greatly appreciated.

Thank you.

For your specific need, it seems like you should utilize the $stateParams.

var result  = service.doSearch(dataObj);
result.then(function(response) {
  $state.go('tab.search-results', {'searchData':response});
}

Incorporate this snippet in your routes file:

.state('tab.search-results', {
  url: '/results/:searchData',
  views: {
      'tab-search-results': {
          templateUrl: 'templates/tab-search-results.html',
          controller: 'SearchResultsCtrl as searchResults'
      }
  }
})

Additionally, update your SearchResultsCtrl with:

.controller($stateParams) {
  console.log($stateParams.searchData) // retrieve search results
}

Please note: If you prefer not to transmit data through the URL, consider using the params key within the .state() method.

.state('tab.search-results', {
  url: '/results',
  params: {
    'searchData':null
  },
  views: {
      'tab-search-results': {
          templateUrl: 'templates/tab-search-results.html',
          controller: 'SearchResultsCtrl as searchResults'
      }
  }
})

After some troubleshooting, I discovered the reason why my view wasn't updating correctly. The solution involved adjusting the views within the sub-view to reference the parent view.

Issue (sub-view named differently from parent):

.....state('tab.search', {
  url: '/search',
  views: {
      'tab-search': {
          templateUrl: 'templates/tab-search.html',
          controller: 'SearchCtrl as search'
      }
  }
})
.state('tab.search-results', {
  url: '/results',
  views: {
      'tab-search-results': {
          templateUrl: 'templates/tab-search-results.html',
          controller: 'SearchResultsCtrl as searchResults'
      }
  }
})

Solution (sub-view now references parent as 'tab-search'):

.....state('tab.search', {
  url: '/search',
  views: {
      'tab-search': {
          templateUrl: 'templates/tab-search.html',
          controller: 'SearchCtrl as search'
      }
  }
})
.state('tab.search-results', {
  url: '/results',
  views: {
      'tab-search': {
          templateUrl: 'templates/tab-search-results.html',
          controller: 'SearchResultsCtrl as searchResults'
      }
  }
})

After some investigation, I believe I have resolved the issue. It appears that the search results page was incorrectly placed under the abstract state called tab.search-results instead of just search-results. This oversight likely caused the problem since there is no specific tab for search results. By renaming the state to simply search-results and updating the $state.go function to use 'search-results' rather than 'tab.search-results', the issue was successfully resolved. Can someone confirm if my approach is correct?
