Preserving Line Breaks In AngularJS

Question

I am working on an app that uses AngularJS. My controller looks like this: function TestCtrl($scope) { $scope.lines = 'var x=1;\nvar y=2;'; } My view looks like this:

Solution 1:

So far, the only way to do it would be using ng-bind-html (-unsafe) (check your angular version because you might need to use $sce) to bind HTML to an element, like this:

Angular 1.0.X:

<code ng-bind-html-unsafe="lines"></code>

Angular 1.2+:

<code ng-bind-html="lines"></code>

but it needs $sce:

$scope.lines = $sce.trustAsHtml('var x=1;<br />var y=2;');

And of course, use the HTML line break: <br />

Here is a working example: http://jsfiddle.net/3fha088t/

Same example here as a snippet:

function TodoCtrl($scope) {
  $scope.lines = 'var x=1;<br />var y=2;';
}

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.8/angular.min.js"></script>
<div ng-app>
  <div ng-controller="TodoCtrl">
      <p>Working version: </p>
        <code ng-bind-html-unsafe="lines"></code>
      <p>Original version: </p>
      <code>{{lines}}</code>
  </div>
</div>

Angular 1.2 version, using $sce:
