标签： javascript angularjs angular-file-upload

我需要使用angular-file-upload指令（https://github.com/nervgh/angular-file-upload）。

我从github获取了html以及控制器示例：

HTML：

<body ng-controller="GeekController" nv-file-drop="" uploader="uploader" filters="queueLimit, customFilter">
<div class="container">
    <div class="navbar navbar-default">
        <div class="navbar-header">
            <a class="navbar-brand" href="https://github.com/nervgh/angular-file-upload">Angular File Upload</a>
        </div>
        <div class="navbar-collapse collapse">
            <ul class="nav navbar-nav">
                <li class="active dropdown">
                    <a href="#" class="dropdown-toggle" data-toggle="dropdown">Demos <b class="caret"></b></a>
                    <ul class="dropdown-menu">
                        <li class="active"><a href="#">Simple example</a></li>

                    </ul>
                </li>
                <li><a href="https://github.com/nervgh/angular-file-upload">View on Github</a></li>
                <li><a href="https://raw.github.com/nervgh/angular-file-upload/master/angular-file-upload.min.js">Download</a></li>
            </ul>
        </div>
    </div>
    <div class="row">
        <div class="col-md-3">
            <h3>Select files</h3>
            <div ng-show="uploader.isHTML5">

                <div class="well my-drop-zone" nv-file-over="" uploader="uploader">

                <div nv-file-drop="" uploader="uploader" options="{ url: '/foo' }">
                    <div nv-file-over="" uploader="uploader" over-class="another-file-over-class" class="well my-drop-zone">
                        Another drop zone with its own settings
                    </div>
                </div>
            </div>
            <!-- Example: nv-file-select="" uploader="{Object}" options="{Object}" filters="{String}" -->

            Single
            <input type="file" nv-file-select="" uploader="uploader" />

控制器：

angular.module('GeekCtrl', ['angularFileUpload'])
    .controller('GeekController', ['$scope', 'FileUploader', function($scope, FileUploader) {
        var uploader = $scope.uploader = new FileUploader({
            url: 'upload.php'
        });
// FILTERS
        uploader.filters.push({
            name: 'customFilter',
            fn: function(item /*{File|FileLikeObject}*/, options) {
                return this.queue.length < 10;
            }
        });
// CALLBACKS
        uploader.onWhenAddingFileFailed = function(item /*{File|FileLikeObject}*/, filter, options) {
            console.info('onWhenAddingFileFailed', item, filter, options);
        };
        uploader.onAfterAddingFile = function(fileItem) {
            console.info('onAfterAddingFile', fileItem);
        };
        uploader.onAfterAddingAll = function(addedFileItems) {
            console.info('onAfterAddingAll', addedFileItems);
        };
        uploader.onBeforeUploadItem = function(item) {
            console.info('onBeforeUploadItem', item);
        };
        uploader.onProgressItem = function(fileItem, progress) {
            console.info('onProgressItem', fileItem, progress);
        };
        uploader.onProgressAll = function(progress) {
            console.info('onProgressAll', progress);
        };
        uploader.onSuccessItem = function(fileItem, response, status, headers) {
            console.info('onSuccessItem', fileItem, response, status, headers);
        };
        uploader.onErrorItem = function(fileItem, response, status, headers) {
            console.info('onErrorItem', fileItem, response, status, headers);
        };
        uploader.onCancelItem = function(fileItem, response, status, headers) {
            console.info('onCancelItem', fileItem, response, status, headers);
        };
        uploader.onCompleteItem = function(fileItem, response, status, headers) {
            console.info('onCompleteItem', fileItem, response, status, headers);
        };
        uploader.onCompleteAll = function() {
            console.info('onCompleteAll');
        };
        console.info('uploader', uploader);
    }]);

当我运行它时，我收到以下错误：

" "<div class="well my-drop-zone" nv-file-over="" uploader="uploader">"

我需要更改什么才能使其正常工作？

2 个答案:

答案 0 :(得分：0)

在html中使用{{uploader}}来访问控制器的上传器，或者在控制器中执行$ scope.uploader = new FileUplader（...）

答案 1 :(得分：0)

这与"Uploader" must be an instance of FileUploader

类似

您可以在div中使用指令ng-if 

<div class="well my-drop-zone" ng-if="uploader" nv-file-over="" uploader="uploader">
