Angular 1.5 component method templateUrl + function

Question

I\'m trying to get an app working with angular 1.5.0-beta.2

To make a \'directive\' I have the following code:

myApp.component(\'gridshow\', {
  bind         


        

Answer 1

I solved this problem by following technique. This may help you.

Template

<div data-ng-repeat="field in $ctrl.fields track by $index">
  <render-field data-field-type="{{field.type}}"></render-field>
</div>

A component

/**
 * @ngdoc Component
 * @name app.component.renderField
 * @module app
 *
 * @description
 * A component to render Field by type
 *
 * @author Mohan Singh ( gmail::mslogicmaster@gmail.com, skype :: mohan.singh42 )
 */
(function () {
  'use strict';

  angular
    .module('app')
    .component('renderField', {
      bindings: {
        fieldType: '@',
      },
      template: '<div ng-include="$ctrl.templateUrl">',
      controller: [
        function () {
          var $ctrl = this;
          $ctrl.$onInit = initialization;
          $ctrl.$onDestroy = onDestroy;
          $ctrl.$onChanges = onChanges;

          /**
           * public properties
           */
          /**
           * public methods
           */
          /**
           * @function
           * @name initialization
           * @description
           * A component's lifeCycle hook which is called after all the controllers on an element have been constructed and had their bindings initialized
           */
          function initialization() {
          }

          /**
           * @function
           * @name onChanges
           * @description
           * A component's lifeCycle hook which is called when bindings are updated.
           */
          function onChanges(bindings) {
            if(bindings.fieldType && bindings.fieldType.isFirstChange()){
              //$ctrl.fieldType['text' | 'textarea' | 'select' | 'radio']
              $ctrl.templateUrl = 'partials/fields/'+$ctrl.fieldType+'.html';
            }
          }
          /**
           * @function
           * @name onDestroy
           * @description
           * A component's lifeCycle hook which is called when is called on a controller when its containing scope is destroyed. 
           * Usefull to release external resources, watches and event handlers.
           */
          function onDestroy() { }
        }]
    });
})();

Answer 2

@estus solution worked for me until I uglified my scripts. Uglified it gave the following error:

Error: [$injector:unpr] Unknown provider: eProvider <- e

The solution that worked for me is:

['$element', '$attrs', function($element, $attrs) {
    return $attrs.uninterpolatedTemplateUrl;
}]

Answer 3

In 1.5.0-beta.2 templateUrl can be a function that is invoked by injector. $element and $attrs are injected into both template and templateUrl functions in component, as well as any other dependencies.

This means that

  ...
  templateUrl: function ($element, $attrs) {
    // access to $element and $attrs
    ...
    return $attrs.uninterpolatedTemplateUrl;
  }

can be done instead.
