**[jQuery File Uploader](http://blueimp.github.io/jQuery-File-Upload/basic.html)**
[](http://blueimp.github.io/jQuery-File-Upload/basic.html)
这是最受欢迎的 [**jQuery**](http://www.cnblogs.com/lhb25/category/277997.html) 文件上传组件，支持批量上传，拖放上传，显示上传进度条以及校验功能。
支持预览图片、音频和视频，支持跨域上传和客户端图片缩放，支持的服务端平台有：PHP, Python, Ruby on Rails, Java, Node.js, Go 等等。
使用示例：
~~~
$(function() {
'use strict';
// Change this to the location of your server-side upload handler:
varurl = window.location.hostname === 'blueimp.github.io'?
'//jquery-file-upload.appspot.com/': 'server/php/';
$('#fileupload').fileupload({
url: url,
dataType:'json',
done:function (e, data) {
$.each(data.result.files,function (index, file) {
$('<p/>').text(file.name).appendTo('#files');
});
},
progressall:function (e, data) {
varprogress = parseInt(data.loaded / data.total * 100, 10);
$('#progress .progress-bar').css(
'width',
progress +'%'
);
}
}).prop('disabled', !$.support.fileInput)
.parent().addClass($.support.fileInput ? undefined :'disabled');
});

**[DropZoneJS](http://www.dropzonejs.com/)**
[](http://www.dropzonejs.com/)
DropzoneJS 是一个用于现代浏览器的开源的拖放上传插件，最大的特色是即时图片预览功能。
使用方法非常简单，只需添加 class 即可：
[?](#)
<table cellpadding="0" cellspacing="0" border="0"><tbody><tr><td class="code"><div class="container"><div class="line number1 index0 alt2"><code class="html plain"><</code><code class="html keyword">form</code><code class="html color1">id</code><code class="html plain">=</code><code class="html string">"my-awesome-dropzone"</code><code class="html color1">action</code><code class="html plain">=</code><code class="html string">"/target"</code><code class="html color1">class</code><code class="html plain">=</code><code class="html string">"dropzone"</code><code class="html plain">></</code><code class="html keyword">form</code><code class="html plain">></code></div></div></td></tr></tbody></table>
或者手动实例化：
[?](#)
<table cellpadding="0" cellspacing="0" border="0"><tbody><tr><td class="code"><div class="container"><div class="line number1 index0 alt2"><code class="javascript keyword">new</code><code class="javascript plain">Dropzone(</code><code class="javascript string">"div#my-dropzone"</code><code class="javascript plain">, {</code><code class="javascript comments">/* options */</code> <code class="javascript plain">});</code></div></div></td></tr></tbody></table>
可以添加更多参数：
[?](#)
<table cellpadding="0" cellspacing="0" border="0"><tbody><tr><td class="code"><div class="container"><div class="line number1 index0 alt2"><code class="javascript plain">Dropzone.options.myAwesomeDropzone = { maxFilesize: 1 };</code></div></div></td></tr></tbody></table>
发可以自定义事件：
[?](#)
<table cellpadding="0" cellspacing="0" border="0"><tbody><tr><td class="code"><div class="container"><div class="line number1 index0 alt2"><code class="javascript plain">Dropzone.options.myDropzone({</code></div><div class="line number2 index1 alt1"><code class="javascript spaces"/><code class="javascript plain">init:</code><code class="javascript keyword">function</code><code class="javascript plain">() {</code></div><div class="line number3 index2 alt2"><code class="javascript spaces"/><code class="javascript keyword">this</code><code class="javascript plain">.on(</code><code class="javascript string">"error"</code><code class="javascript plain">,</code><code class="javascript keyword">function</code><code class="javascript plain">(file, message) { alert(message); });</code></div><div class="line number4 index3 alt1"><code class="javascript spaces"/><code class="javascript plain">}</code></div><div class="line number5 index4 alt2"><code class="javascript plain">});</code></div><div class="line number6 index5 alt1"><code class="javascript comments">// or if you need to access a Dropzone somewhere else:</code></div><div class="line number7 index6 alt2"><code class="javascript keyword">var</code><code class="javascript plain">myDropzone = Dropzone.forElement(</code><code class="javascript string">"div#my-dropzone"</code><code class="javascript plain">);</code></div><div class="line number8 index7 alt1"><code class="javascript plain">myDropzone.on(</code><code class="javascript string">"error"</code><code class="javascript plain">,</code><code class="javascript keyword">function</code><code class="javascript plain">(file, message) { alert(message); });<span style=</code><code class="javascript string">"line-height: 1.5;"</code><code class="javascript plain">> </span></code></div></div></td></tr></tbody></table>
