作者更新得似乎挺勤快的，先预览下代码：

<script src="angular.min.js"></script>
<!-- shim is needed to support non-HTML5 FormData browsers (IE8-9)-->
<script src="angular-file-upload-shim.min.js"></script>
<script src="angular-file-upload.min.js"></script> <div ng-app="fileUpload" ng-controller="MyCtrl">watching model:<div class="button" ng-file-select ng-model="files">Upload using model $watch</div><div class="button" ng-file-select ng-file-change="upload($files)">Upload on file change</div>Drop File:<div ng-file-drop ng-model="files" class="drop-box" drag-over-class="dragover" ng-multiple="true" allow-dir="true"accept=".jpg,.png,.pdf">Drop Images or PDFs files here</div><div ng-no-file-drop>File Drag/Drop is not supported for this browser</div>
</div>
```
```javascript
//inject angular file upload directives and services.
var app = angular.module('fileUpload', ['angularFileUpload']);app.controller('MyCtrl', ['$scope', '$upload', function ($scope, $upload) {$scope.$watch('files', function () {$scope.upload($scope.files);});$scope.upload = function (files) {if (files && files.length) {for (var i = 0; i < files.length; i++) {var file = files[i];$upload.upload({url: 'upload/url',fields: {'username': $scope.username},file: file}).progress(function (evt) {var progressPercentage = parseInt(100.0 * evt.loaded / evt.total);console.log('progress: ' + progressPercentage + '% ' + evt.config.file.name);}).success(function (data, status, headers, config) {console.log('file ' + config.file.name + 'uploaded. Response: ' + data);});}}};
}]);
```
