How to toggle a boolean variable in AngularJS when transitioning between states

Just getting started with AngularJS and trying to figure out how to tackle this issue.
I have set up the following route:

name: "Tracker",
url: "/tracker/:period",

and I have 3 distinct states for which I've created 3 separate functions to facilitate switching between URLs in my application.

 viewYearly() { 
    this.$state.go("Tracker", {"period": 'year'});
    this.viewWeek = false;
    this.viewMonth = false;
    this.viewYear = true;
  };

viewMonthly() { 
    this.$state.go("Tracker", {"period": 'month'});
    this.viewWeek = false;
    this.viewMonth = true;
    this.viewYear = false;
  };  

viewWeekly() { 
    this.$state.go("Tracker", {"period": 'week'});
    this.viewWeek = true;
    this.viewMonth = false;
    this.viewYear = false;
  };  

While the URL change works smoothly, I'm encountering an issue. I've declared these 3 variables:

viewWeek: boolean;
viewMonth: boolean;
viewYear: boolean;

in the controller so that I can use them with ng-show to hide certain content based on the URL being viewed.

As demonstrated in the functions, I assign True depending on the URL accessed.

The problem lies in the fact that it's functioning but not accurately - when I click a button in my view to switch to a Monthly URL, the new URL loads, BUT the ng-show utilizing the viewMonth variable only takes effect after a SECOND click of the button.

So, upon first click, the URL changes; on the second click, the corresponding actions are triggered using that boolean. I believe the solution might be simple, potentially related to how I initialized those variables. Any suggestions?

Edit 1: here is the button to alter the URL:

<div class="pull-right" ng-click="vm.viewYearly()"><i>View Year</i></div>

Edit 2:

views: {
      header: {
        templateUrl: "Views/Tracker/Header.htm",           
        controller: "trackerHeadCtrl",
        controllerAs: "vm"

Edit 3
SOLUTION:

I managed to resolve it by making the following adjustment,

viewYearly() { 
this.$state.go("Tracker", {"period": 'year'});

this function handles the state change, and instead of declaring and toggling 3 boolean variables, I utilized a function:

get viewMonth(): boolean {
        return this.period === "year";
    };

Appreciate your guidance regardless!

Answer №1

One issue lies in the fact that updates to variables like viewWeek, viewMonth, and viewYear are occurring outside of Angular's $digest circle. To resolve this quickly, consider enclosing these statements within a $timeout() function or utilizing $scope.$applyAsync().

Answer №2

The recommended approach is to change the state upon clicking, which will then set the variables accordingly. It's important to utilize the state as the primary source of truth in this scenario.

  displayYearlyData() { 
    this.$state.go("Tracker", {"period": 'year'});
  };

  displayMonthlyData() { 
    this.$state.go("Tracker", {"period": 'month'});
  };  

  displayWeeklyData() { 
    this.$state.go("Tracker", {"period": 'week'});
  };

  // Activate function
  function activate() {
    if ($state.params.period == 'year') {
      // Set necessary variables here based on yearly data
    }
  }
