Question

What is the best way to update a page and retrieve fresh data from a service in Angular?

On my webpage, there is a table and two charts coming from three different controllers. I am looking for a way to refresh all of them simultaneously by clicking on a single refresh button. This will allow the data to be fetched from the webservice again and update the page accordingly.

I have attempted a few ideas:

$scope.refreshChart = function(){
    alert("refresh"); 
    // $scope.dashloader = true;
  $state.go('plm.creator');
  // $scope.dashloader = false;
   console.log("On page refresh called; not from dashboard page");


}

Unfortunately, these solutions are not meeting my expectations. Any assistance would be greatly appreciated.

Answer №1

If you're looking to refresh multiple controllers at once, one approach you can consider is using $scope.$broadcast(name, args) to trigger an event (you can choose any name for the event) that all controllers can listen for and then execute their code to refresh.

To listen for the event in a controller, you would use $scope.$on(event, listener)

For example, one controller could broadcast the event like this:

$scope.$broadcast('MyRefreshEvent', args);

And another controller could listen for the event like this:

$scope.$on('MyRefreshEvent', function (args) {
    // Perform refresh actions
});

If you need to refresh the entire page, you can achieve this with the following code snippet:

$state.transitionTo($state.current, $stateParams, {
            reload: true,
            inherit: false,
            notify: true
        });

However, I would advise against using this method unless absolutely necessary. It would be better to consider refactoring your code to streamline it by consolidating controllers that rely on multiple factories.
