该页面使用angularjs和ionic制成。我是棱角和离子的新手。需要在名字之前或名字旁边上传图片。可以使用该离子图标“”上传图像。使用了ng-upload，但无法正确理解。

该怎么做？

Answer 1

您是否安装了Angular File Upload？以下是使用Angular File Upload的步骤：在我们的代码中使用它之前，我们需要安装Angular File Upload。

打开命令提示符
转到您的项目根目录
运行命令npm install angular-file-upload 安装angular-file-upload后，我们需要将其作为依赖项添加到我们的angular模块中。
要注入依赖项，请运行以下命令：

var app = angular.module（'my-app'，[ 'angularFileUpload' ]）;

现在您可以在代码中的任何地方使用它。

例如：在HTML中：

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

在uguglar模块中：

.module('app', ['angularFileUpload'])
.controller('AppController', function($scope, FileUploader) {
    $scope.uploader = new FileUploader();
});

您可以在此link上找到简单的示例。希望对您有所帮助。
