ur.file: Native HTML5-based file input bindings for AngularJS

Example

l ng-app="myApp">

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.1/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.1/angular-resource.min.js"></script>
<script src="angular-file.js"></script>
<script>
    var app = angular.module('myApp', ['ur.file', 'ngResource']);

    app.controller('FileController', function($scope, $resource) {

        var Files = $resource('/files/:id', { id: "@id" });

        angular.extend($scope, {

            model: { file: null },

            upload: function(model) {
                Files.prototype.$save.call(model.file, function(self, headers) {
                    // Handle server response
                });
            }
        });

What's happening here?

• ng-model: You can now use it for <input type="file" /> elements, just like normal. Bind it to a scope property, and it will be assigned a File object when the file input is populated. However, this is effectively a read-only property, due to the security restrictions around manipulating file uploads with JavaScript.

• change: Typical change event. Triggered when a file is selected.

• Files.prototype.$save.call(): Treats the file object as an instance of $resource, and POSTs the raw contents of the file to the configured URL. The upload handler also sets four headers: X-File-Name, X-File-Size, X-File-Last-Modified, and Content-Type.

The X-File-Name header is encoded with URL encoding.
