Why is the UI Router controller failing to function properly after loading the view from the $templateCache?

I've been utilizing gulp-angular-templatecache to convert my filename.view.html files into a consolidated templates.js file.

Afterwards, I use $stateProvider to define states and fetch the templates from $templateCache, including an abstract "root" state.

$stateProvider
    .state('app', {
        abstract: true,
        template: '<div ui-view></div>'
    })
    .state('app.login', {
        url: '/login',
        template: $templateCache.get('components/login/login.html'),
        controller: 'LoginController as login'
    });

Thus far, everything seems to be loading correctly on the page, but for some reason, I am unable to get the controllers to function properly.

The modules and corresponding controllers are fairly straightforward:

(function () {

    'use strict';

    angular
        .module('login', [])
        .controller('LoginController', LoginController);

    function LoginController() {

        var vm = this;

        vm.loginID = 'test';
        vm.password = 'test';

        vm.doLoginRequest = function () {
            console.log('Performing login request...');
        }

    }

})();

I have attempted different methods to resolve this issue, such as:

  • Moving the template to the .run(...) part of the module and adding it to $templateCache there instead
  • Exploring variations of template, templateUrl, and templateProvider in the state configuration
  • Eliminating the controllerAs syntax from the state and opting for ng-controller instead
  • Utilizing the traditional controller syntax (without controllerAs syntax)

If anyone has any suggestions on how to fix this problem, I would greatly appreciate it. I've been trying to figure it out for hours!

Answer №1

After some investigation, I discovered that the problem stemmed from using a <form> element in my login template that was not compatible with Angular. It seems that I may have incorrectly implemented the <form> which caused it to clash with Angular's functionality.

Once I removed the <form> element, the issue was resolved.

Instructions on preloading templates:

1) Start your task to create the template.js view file

2) Pre-load all templates in your main index file

  <script src="build/templates.js"></script>

3) Include your module as a dependency (automated tasks might generate a separate module, so verify the module name)

angular.module('app', ['templates'])

4) In the app.config section, refer to the views as if you were loading them without caching

 .state('home', {
        url: '/home',
        views: {
            "@": {
                controller: 'homeController',
                templateUrl: 'app/views/home.html'

            },
        }

    })
