html - Angularjs fallback, hide for none javascript users

I know about the script-tag for adding content that none javascript users can read.

What is the best way to hide html blocks that is created for angularjs?

Example:

<div>
{{this_code_is_converted_to_angular_js_code_when_javascript_is_active}}
</div>

The line above is not that beautiful for a none javascript user. What is the best way to remove it if the user is not using javascript?

are you using the ng-view directive? If i'm looking at source in developer tools for chrome it doesn't look like you are. You have everything inside the same html file. You should make a SPA application where Angular switches out your views. – furier Commented Jun 10, 2014 at 13:47
No I'm just dumping it in so far. Maybe a "SPA"-thing would be better. I'm quite new to Angularjs. – Jens Törnell Commented Jun 10, 2014 at 13:51

Use the <noscript> tag to display content when JavaScript is not enabled.

Also the main.html file should not have any {{content}} tags, instead you should have sub views which are loaded into the <div ng-view=""></div>

This way if JavaScript is not enabled, only content in the noscript tag will be displayed because the ng-view div is empty, as AngularJS is JavaScript and will never insert anything into the ng-view div.

Example HTML

<!DOCTYPE html>
<!--[if lt IE 7]>      <html lang="en" ng-app="myApp" class="no-js lt-ie9 lt-ie8 lt-ie7"> <![endif]-->
<!--[if IE 7]>         <html lang="en" ng-app="myApp" class="no-js lt-ie9 lt-ie8"> <![endif]-->
<!--[if IE 8]>         <html lang="en" ng-app="myApp" class="no-js lt-ie9"> <![endif]-->
<!--[if gt IE 8]><!--> <html lang="en" ng-app="myApp" class="no-js"> <!--<![endif]-->
<head>
  <meta charset="utf-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <title>My AngularJS App</title>
  <meta name="description" content="">

  <script src="bower_ponents/html5-boilerplate/js/vendor/modernizr-2.6.2.min.js"></script>
</head>
<body>
  <!--[if lt IE 7]>

  <![endif]-->

  <div ng-view></div>
  <noscript>Enable JavaScript to view this web page.</noscript>

  <!-- In production use:
  <script src="//ajax.googleapis./ajax/libs/angularjs/x.x.x/angular.min.js"></script>
  -->
  <script src="bower_ponents/angular/angular.js"></script>
  <script src="bower_ponents/angular-route/angular-route.js"></script>
  <script src="js/app.js"></script>
  <script src="js/services.js"></script>
  <script src="js/controllers.js"></script>
  <script src="js/filters.js"></script>
  <script src="js/directives.js"></script>
</body>
</html>

If you just want to hide elements you can use ng-cloak https://docs.angularjs/api/ng/directive/ngCloak

You have a few options...

Since you specifically don't want to display HTML block for NON-Angular (non-javascript), then you should ONLY place that HTML code within either:

use ngBindTemplate (preferred):

<script>
  function Ctrl($scope) {
    $scope.salutation = 'Hello';
    $scope.name = 'World';
  }
</script>
<div ng-controller="Ctrl">
 Salutation: <input type="text" ng-model="salutation"><br>
 Name: <input type="text" ng-model="name"><br>
 <pre ng-bind-template="{{salutation}} {{name}}!"></pre>
</div>

or... ngBind:

<script>
  function Ctrl($scope) {
    $scope.name = 'Whirled';
  }
</script>
<div ng-controller="Ctrl">
  Enter name: <input type="text" ng-model="name"><br>
  Hello <span ng-bind="name"></span>!
</div>

The main difference being that "...unlike ngBind, the ngBindTemplate can contain multiple {{ }} expressions. This directive is needed since some HTML elements (such as TITLE and OPTION) cannot contain SPAN elements.": https://docs.angularjs/api/ng/directive/ngBindTemplate

In your specific example/question:

 <div ng-bind="hide-this-when-no-js">
   {{this_code_is_converted_to_angular_js_code_when_javascript_is_active}}
 </div>

I don't know if this is what you are looking for but if you don't want to display {{ }} marks in your page when javascript is not enabled you should try using ng-bind and/or ng-bind-template instead.
