To display the selected pdf file in angular js while uploading - angularjs

Question

Hi Here I have to upload single/multiple files in angular js . I have used the below link for uploading files. In this they have uploaded the images but instead I have to upload pdf and image.
<div class="container">
<div ng-controller="MyCtrl" class="row">
<button class="btn btn-primary pull-right" ng-hide="images.length == 0" ng-click="clearAll()">Clear All</button>
<h3 ng-bind="name"></h3>
<input type="file" ng-click="$event = $event" ng-model="display" multiple onchange="angular.element(this).scope().upload(event)" accept="image/png, image/jpeg, image/gif" />
<div class="row">
<div class="col-md-12"> <span ng-repeat='img in images'> <a href="#" ng-click="setImage($index)">
<img ng-src="{{img}}"
alt="Generic placeholder thumbnail" style="max-height:100px;" class="thumbnail"/>
</a>
</span>
</div>
</div>
<img ng-src="{{display}}" ng-hide="!display" />
<h4>You have upload {{images.length}} images this session.
</h4>
</div>
</div>
var myApp = angular.module('myApp', []);
myApp.controller('MyCtrl', function ($scope) {
$scope.name = "Select Files to Upload";
$scope.images = [];
$scope.display = $scope.images[$scope.images.length - 1];
$scope.setImage = function (ix) {
$scope.display = $scope.images[ix];
}
$scope.clearAll = function () {
$scope.display = '';
$scope.images = [];
}
$scope.upload = function (obj) {
var elem = obj.target || obj.srcElement;
for (i = 0; i < elem.files.length; i++) {
var file = elem.files[i];
var reader = new FileReader();
reader.onload = function (e) {
$scope.images.push(e.target.result);
$scope.display = e.target.result;
$scope.$apply();
}
reader.readAsDataURL(file);
}
}
})
Thanks in advance.
