AngularJS format array values in textarea

Question

I have a angularJS application, in which I have an array.

  $scope.data[0] =  x1;
  $scope.data[1] =  x2;

and a text area

Answer 1

This is exactly what ng-list does:

This also works on all other kinds of inputs as it hooks into ngModels parsers/formatters.

See this fiddle: http://jsfiddle.net/xbYzT/1/

The problem with this is that ng-list always joins with a ',' as the separator, so it's not really bi-directional.
