As ng-bind-html-unsafe is deprecated, you can use this code instead.
You need to create function inside your controller:
$scope.toTrustedHTML = function( html ){
return $sce.trustAsHtml( html );
}
and use something like this in your view:
<span ng-bind-html='toTrustedHTML( myHTMLstring )'></span>
Don't forget to inject $sce:
AppObj.controller('MyController', function($scope, $sce) {
//your code here
});
