Question

Bootstrap-bootstrap有没有形式简单的文件上传组件

Answer 1

Fine Uploader特点如下:

Fine Uploader Features:

A：支持文件上传进度显示.

B：文件拖拽浏览器上传方式

C：Ajax页面无刷新.

D：多文件上传.

F：跨浏览器.

E：跨后台服务器端语言.

在Git Hub上Fine Uploader上下载打包源码,在Php Designer 8中打开其源码可以看到其源码结构如下:

2013-01-04_162943

在根目录中可以看到Client客户端调用需要使用文件.Server目录则是对应不同语言Perl/Php/Asp.net[VB]等版本实现.test目录则有包含一个完整本地Sample Demo.可供参考.

如何快速构建一个简单Demo? 其实官方在Basic-Demo-Page上已经给出一个简单的演示.这里基于Bootstrap方式构建.

首先新建一个Html空白页面.命名FineUploderDemo.html.添加如下CSS引用如下:

1: <link href="static/css/fineuploader.css" rel="stylesheet">
2: <link href="static/css/bootstrap.min.css" rel="stylesheet">
这两个文件时必须引用的.fineuploader.css则是对应下载Fine Uploder源码Client目录下.fineuploder.css 提供JS脚本中所需的CSS样式，主要包括按钮的样式、进度显示的样式以及上传结果的样式.添加JavaScript文件引用如下:

1: <script src="static/script/fineupload/header.js"></script>
2: <script src="static/script/fineupload/util.js"></script>
3: <script src="static/script/fineupload/button.js"></script>
4: <script src="static/script/fineupload/handler.base.js"></script>
5: <script src="static/script/fineupload/handler.form.js"></script>
6: <script src="static/script/fineupload/handler.xhr.js"></script>
7: <script src="static/script/fineupload/uploader.basic.js"></script>
8: <script src="static/script/fineupload/dnd.js"></script>
9: <script src="static/script/fineupload/uploader.js"></script>
其中uploder.js和uploder.basic.js则是前端的所有上传功能都在该脚本中实现.必须引用.

同时添加client目录下processing和loading两张进度显示所需要的动态图片.该图片都在fineuploder.css文件调用.

在body添加如下Code:

1: <div id="bootstrapped-fine-uploader"></div>
2: <script>
3: function createUploader() {
4: var uploader = new qq.FineUploader({
5: element: document.getElementById('bootstrapped-fine-uploader'),
6: request: {
7: endpoint: 'server/handlerfunction'
8: },
9: text: {
10: uploadButton: '<i class="icon-upload icon-white"></i> Click me now and upload a product image'
11: },
12: template:
13: '<div class="qq-uploader span12">' +
14: '<pre class="qq-upload-drop-area span12"><span>{dragZoneText}</span></pre>' +
15: '<div class="qq-upload-button btn btn-success" style="width: auto;">{uploadButtonText}</div>' +
16: '<span class="qq-drop-processing"><span>{dropProcessingText}</span>'+
17: '<span class="qq-drop-processing-spinner"></span></span>' +
18: '<ul class="qq-upload-list" style="margin-top: 10px; text-align: center;"></ul>' +
19: '</div>',
20: classes: {
21: success: 'alert alert-success',
22: fail: 'alert alert-error'
23: },
24: debug: true
25: });
26: }
27:
28: window.onload = createUploader;
29: </script>
这是基于Bootstrap实现对Fine Uploader最简单的前端调用.前端一般需要做两件事A:添加Css+Js文件引用.B：在Js中实例化qq.FineUploder对象.运行效果
