我已经基于这个 sample application 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完成我自己的工作，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 uploader ，并发现了这个 JQuery-file-upload变得很棒(我不想重新发明轮子......因为我很“匆忙”)。以前有人这样做过吗？ 到目前为止，我已经下载了 zip 文件并在 WampServer (PHP) 上运行它，效果很好(我阅读了设置手册)。在应用程序中合并/附加它(使用小部件)怎么样？你是如何做到的(我对插件没有太多经验)
代码部分:
tpl/ResourcesView.html(因此，如果我们只从演示中获取有趣的部分):
<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>Add files...</span>
<input type="file" name="files[]" multiple>
</span>
<button type="submit" class="btn btn-primary start">
<i class="icon-upload icon-white"></i>
<span>Start upload</span>
</button>
<button type="reset" class="btn btn-warning cancel">
<i class="icon-ban-circle icon-white"></i>
<span>Cancel upload</span>
</button>
<button type="button" class="btn btn-danger delete">
<i class="icon-trash icon-white"></i>
<span>Delete</span>
</button>
<input type="checkbox" class="toggle">
</div>
<!-- The global progress information -->
<div class="span5 fileupload-progress fade">
<!-- The global progress bar -->

</div>
<!-- The extended global progress information -->
<div class="progress-extended"> </div>
</div>
</div>
<!-- The loading indicator is shown during file processing -->
<div class="fileupload-loading"></div>
<br>
<!-- The table listing the files available for upload/download -->
<table role="presentation" class="table table-striped"><tbody class="files" data-toggle="modal-gallery" data-target="#modal-gallery"></tbody></table>
</form>
</div>
<!-- The template to display files available for upload -->
<script id="template-upload" type="text/x-tmpl">
{% for (var i=0, file; file=o.files[i]; i++) { %}
<tr class="template-upload fade">
<td class="preview"><span class="fade"></span></td>
<td class="name"><span>{%=file.name%}</span></td>
<td class="size"><span>{%=o.formatFileSize(file.size)%}</span></td>
{% if (file.error) { %}
<td class="error" colspan="2"><span class="label label-important">{%=locale.fileupload.error%}</span> {%=locale.fileupload.errors[file.error] || file.error%}</td>
{% } else if (o.files.valid && !i) { %}
<td>
<div class="progress progress-success progress-striped active" role="progressbar" aria-valuemin="0" aria-valuemax="100" aria-valuenow="0"><div class="bar" style="width:0%;"></div></div>
</td>
<td class="start">{% if (!o.options.autoUpload) { %}
<button class="btn btn-primary">
<i class="icon-upload icon-white"></i>
<span>{%=locale.fileupload.start%}</span>
</button>
{% } %}</td>
{% } else { %}
<td colspan="2"></td>
{% } %}
<td class="cancel">{% if (!i) { %}
<button class="btn btn-warning">
<i class="icon-ban-circle icon-white"></i>
<span>{%=locale.fileupload.cancel%}</span>

{% } %}</td>
</tr>
{% } %}
</script>
<!-- The template to display files available for download -->
<script id="template-download" type="text/x-tmpl">
{% for (var i=0, file; file=o.files[i]; i++) { %}
<tr class="template-download fade">
{% if (file.error) { %}
<td></td>
<td class="name"><span>{%=file.name%}</span></td>
<td class="size"><span>{%=o.formatFileSize(file.size)%}</span></td>
<td class="error" colspan="2"><span class="label label-important">{%=locale.fileupload.error%}</span> {%=locale.fileupload.errors[file.error] || file.error%}</td>
{% } else { %}
<td class="preview">{% if (file.thumbnail_url) { %}
<a href="{%=file.url%}" title="{%=file.name%}" rel="gallery" download="{%=file.name%}"><img src="{%=file.thumbnail_url%}"></a>
{% } %}</td>
<td class="name">
<a href="{%=file.url%}" title="{%=file.name%}" rel="{%=file.thumbnail_url&&'gallery'%}" download="{%=file.name%}">{%=file.name%}</a>
</td>
<td class="size"><span>{%=o.formatFileSize(file.size)%}</span></td>
<td colspan="2"></td>
{% } %}
<td class="delete">
<button class="btn btn-danger" data-type="{%=file.delete_type%}" data-url="{%=file.delete_url%}">

<span>{%=locale.fileupload.destroy%}</span>
</button>
<input type="checkbox" name="delete" value="1">
</td>
</tr>
{% } %}
</script>
然后是主干部分
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;
}
});
main.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">

<meta name="description" content="">
<meta name="author" content="">

最佳答案
1) 主干应用程序，具有包含文件输入的 View :
<div class="fileUploadView">
<input id="fileUpload" name="file" type="file"/>
</div>
2) 要添加该插件，您的服务器上有 blueimp fileupload 插件 javascript 文件，并从 <head> 引用。或<body>你的页面？我通常有一个文件夹，例如用于插件和小部件的供应商/名称。其中包括以下所有内容:
<!-- 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) 为了使其看起来像您在页面中提供并引用的 jquery.fileupload-ui.css 的演示:
<link rel="stylesheet" href="/vendor/fileUpload/css/jquery.fileupload-ui.css">
4) 在 View 中调用 render() 后，假设所有必需的文件都在窗口中并且 View 已渲染，您可以执行以下操作:
$('#fileUpload', this.el).fileupload();
如果您已准备好所有资源，那么应该会显示小部件。最后，您需要将其指向接收文件上传的网址:
$('#fileUpload', this.el).fileupload('option', {
url: '/uploadreceiver'
});
