Leverage the power of both ui-sref and $state.go for seamless state transitions in Angular's ui

Currently, I am in the process of constructing a sign-up form that will collect user input and then transition to a logged-in state with a template tailored specifically for this new user.

To achieve this, my understanding is that I need to utilize ng-submit() in the HTML template along with $state.go() in the controller.

Here's how the code looks:

<form ng-submit="register(name, password)">
  ...
  <input class="btn btn-success btn-lg btn-block" type="submit" value="Sign Up">
</form>

And here is the controller implementation:

angular.module('myApp').controller('RegisterController',
        ['$scope','userService', function($scope, userService) {
          $scope.register = function(name, password) {
            userService.register(name, password);
            $state.go("app.home");
          }
}])

Although, I have noticed that I only require using $state.go() in a few instances, since most cases can be handled by using ui-sref in the HTML template. Is it considered good practice to mix ui-sref and $state.go()? While both essentially accomplish the same goal as per the ui-router documentation, having state transitions split between two different areas (template and controller) seems like it may lead to code smell.

I attempted combining ui-sref with ng-submit, but unfortunately, the ng-submit was disregarded. So, what would be the recommended approach in this scenario?

Answer №1

When you use the ui-sref directive, it simply creates an href attribute with the URL for the specified state.

If you need to navigate to a different state based on user interaction that cannot be accomplished using an href (such as submitting a form), then you will have to utilize $state.go.

Think of it this way:

  • ui-sref: Binds an href attribute to an element.
  • $state.go: Transitions to another state, controlled by your JavaScript code.

Answer №2

It is essential to follow this practice as it is the most effective way of achieving the desired outcome. Trying to use both ui-sref and ng-submit simultaneously would result in being redirected to a new state, which defeats the purpose.

Utilizing ng-submit for form submission is highly recommended, while using $state.go allows for seamless transitions between states within your controller.

There are instances where transitioning to another state through the controller is necessary, making it perfectly acceptable to combine these methods.
