我已经基于这个示例应用程序启动了一个 jquery/backbone.js 应用程序，并对其进行了相当大的修改以做我自己的事情，但 MVC 概念仍然存在。到目前为止，一切正常，我基本上只是添加我的内容/模型/等。当我也需要的时候。

我需要实现一个基本的文件上传器，发现这个JQuery-file-upload很棒（我不想重新发明轮子......因为，我很“匆忙”）。以前有人做过吗？到目前为止，我已经下载了 zip 文件并在 WampServer (PHP) 上运行它，它工作得很好（我阅读了安装手册）。在应用程序中合并/附加它怎么样（使用小部件）？你是怎么做的（我对插件没有太多经验）

代码部分：

tpl/ResourcesView.html（所以如果我们只从演示中提取有趣的部分）：

<div class="content fixed-fixed">              
<!-- The file upload form used as target for the file upload widget -->
    <form id="fileupload" action="plugin/jquery-fileupload/server/php/" method="POST" enctype="multipart/form-data">
        <!-- The fileupload-buttonbar contains buttons to add/delete files and start/cancel the upload -->
        <div class="row fileupload-buttonbar">
            <div class="span7">
                <!-- The fileinput-button span is used to style the file input field as button -->
                <span class="btn btn-success fileinput-button">
                    <i class="icon-plus icon-white"></i>

                </span>

                    <span>Start upload</span>

        {% } else { %}

            </button>
            <input type="checkbox" name="delete" value="1">
        </td>
    </tr>
{% } %}
</script>

然后是骨干部分

js/views/resources.js（渲染模板）：

window.ResourcesView = Backbone.View.extend({

    initialize:function () {
        this.render();
        $('#fileupload').fileupload();
           $('#fileUpload', this.el).fileupload('option', {
           url: '/resources'
        });
    },

    render:function () {
        $(this.el).html(this.template());
        return this;
    }

});

主.js：

var AppRouter = Backbone.Router.extend({

    routes: {
        "resources"         : "resources"},
    resources: function(){
        if (!this.resourcesView) {
            this.resourcesView = new ResourcesView();
        }
        $('#content').html(this.resourcesView.el);

        this.leftMenuView.selectMenuItem('resource-link');

    }
});

utils.loadTemplate(['ResourcesView' ], function() {
    app = new AppRouter();
    Backbone.history.start();
});

最后，我的 index.html：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <title>MPact App</title>
    <meta name="description" content="">
    <meta name="author" content="">

    <style>
        body {
            padding-top: 60px; /* 60px to make the container go all the way to the bottom of the topbar */
        }
    </style>
    <link href="css/bootstrap.css" rel="stylesheet">

    <!-- CSS to style the file input field as button and adjust the Bootstrap progress bars -->

1）主干应用程序，具有文件输入的视图：

<div class="fileUploadView">
  <input id="fileUpload" name="file" type="file"/>
</div>

2) 要添加插件，您的服务器上有 blueimp fileupload 插件 javascript 文件并从您的页面<head>或<body>页面引用？我通常有一个文件夹，例如 vendor/NAME 用于插件和小部件。这些包括以下所有内容：

<!-- The Iframe Transport is required for browsers without support for XHR file uploads -->
<script src="/vendor/fileUpload/js/jquery.iframe-transport.js"></script>
<!-- The basic File Upload plugin -->
<script src="/vendor/fileUpload/js/jquery.fileupload.js"></script>
<!-- The File Upload file processing plugin -->
<script src="/vendor/fileUpload/js/jquery.fileupload-fp.js"></script>
<!-- The File Upload user interface plugin -->
<script src="/vendor/fileUpload/js/jquery.fileupload-ui.js"></script>

3) 为了使它看起来像您在页面中提供并引用了 jquery.fileupload-ui.css 的演示：

<link rel="stylesheet" href="/vendor/fileUpload/css/jquery.fileupload-ui.css">

4) 在视图中调用 render() 后，假设所有必要的文件都在窗口中并且视图已被渲染，您可以这样做：

$('#fileUpload', this.el).fileupload();

如果您拥有所有资产，则应该显示小部件。最后，您需要将其指向您的 url 以接收文件上传：

$('#fileUpload', this.el).fileupload('option', {
  url: '/uploadreceiver'
});

实际渲染发生在 main.js 中，因此我将文件上传初始化放在了错误的位置（我想我错过了阅读或文档上的内容）。

资源.js：

window.ResourcesView = Backbone.View.extend({

    initialize:function () {
        this.render();
    },

    render:function () {
        $(this.el).html(this.template());
        return this;
    }

});

主.js：

resources: function(){
    if (!this.resourcesView) {
        this.resourcesView = new ResourcesView();
    }
    $('#content').html(this.resourcesView.el);
    $('#fileupload').fileupload();
       $('#fileUpload', this.el).fileupload('option', {
       url: '/resources'
    });

    this.leftMenuView.selectMenuItem('resource-link');

},
