here is my downloadable link : download.xxxxxx.com/yyyyy.json
for company policy reason, I use xxxxxx and yyyyy to illustrate domain and json file name. but I have tested on my end, this is a downloadable link.
HTML
<input type="button" class="btn-round btn-primary" ng-href="winlink" value="Download">
Controller
$scope.winlink = 'http://download.xxxxxx.com'+ '/' + $scope.name;
the problem here is ng-href doesn't work at all. When I click the button, nothing happens.
