UI-Router, how to get the name of the 'state' And How send it to the function That brings Template state

问题

I start in angular

And I want to write a function that will bring template For each state

And just when need it. As the principle of "Lazy loading"

And after that keep it in the cache when it's the first time

I wrote this code But I have errors, and I do not know what I'm wrong, Some things I did not understand in angular so I understand the problematic in my code

this is all my code :

http://plnkr.co/edit/qzKJUwNImVX8EGb3ymnT?p=preview

var app = angular.module('myApp', ['ui.router']);

var getTemplate = function(name) {

  templates = {pages: 'content of pagesTemplate.html. I very wish !!'};

  if (name in templates) {
    return templates[name];
  }

  $http.get(name + 'Template.html' ).then(
    function(response){
      templates[name] = response.data;
      return templates[name];
    }
  );
};

app.config(function($stateProvider, $urlRouterProvider, $locationProvider) {

  $locationProvider.html5Mode({
    enabled: true,
    requireBase: false
  });

  $stateProvider
    .state('pages', {
      url: '/:page',

      templateUrl: getTemplate(),  // Exist in line 18 ▲ 
                // Here I want to build a function or calld a function
                // To bring me the template of the page
                // But I want it will be stored in the cache, if it comes first time
                // And next time I will take it from the cache by the name of the 'state' ('pages').

      controller: function($stateParams) {
        alert($stateParams.page);

        // And here I want to receive From the server The content of the page By $stateParams.page

      }
    })

});

<a ui-sref="pages({ page: 'home' })">Home</a>
<div ui-view=""></div>

There is updated and working example

The best we can do is to combine two great features:

UI-Router templateProvider to dynamically built template path and
angular $templateRequest which is so smart, that it does load and caches templates for us

here is the templateUrl replacement:

// instead of templateUrl
templateProvider: ['$templateRequest', '$stateParams', 
    function($templateRequest,$stateParams){
      var pathToTemplate = 'pagesTemplate.html';

      // do some magic with pathToTemplate

      return $templateRequest(pathToTemplate);

    }],

Check it here in action

And also observe these:

Using templateRequest in angular + typescript ($templateRequest not a function)
ui router nested views condtions
