JQuery上传插件uploadify整理（Options）

下载现在有两个版本了，我此次使用的依然是Flash版本的，虽然现在绝大部分浏览器都兼容HTMKL5，目前位置，除了做手机项目外，一般我们项目中不允许使用HTML5标签。

属性介绍(Options)

auto：是否自动上传，默认值true。如果设置为false，上传文件将会被放入到一个队列中，需要调用upload方法才会将队列中的文件上传到服务器，具体参见upload方法介绍。

 $(function () {

     $("#upload").uploadify({

         auto: false,

         swf: '/uploadify/uploadify.swf',

         uploader: '/ashx/upload.ashx'

     });

 });

效果图：

注意：不调用upload方法，将会永久在队列中。不会自动提交到服务器。

buttonClass：按钮的样式，默认值(Empty String)。想要设置样式还是很麻烦的，首先你要覆盖掉原有的样式，原有样式在uploadify.css（你也可以对次css文件进行精简），这个属性一般不怎么用，项目中让美工切button图片，直接赋值给buttonImage。这里只给出一个使用的例子：

 .some{

     background-color:Red;

     background-image:none;

 }

buttonClass

效果：

buttonCursor：鼠标悬停在按钮上的样式，默认值hand(手型)，可设置为arrow(箭头)。

buttonImage：按钮的图片路径，默认值null。这里需要强调一下，项目中不要把uploadify.css原封不动的引用，因为里面有默认样式。

最外层的div自带uploadify样式，可能会导致你新加的样式无效。

buttonText：按钮的文本，默认值'SELECT FILES'。

checkExisting：检测文件是否已经存在，提示是否执行覆盖操作。默认值false。

 $(function () {

     $("#upload").uploadify({

         'buttonText': '神马',

         'checkExisting': '/ashx/checkExisting.ashx',

         'swf': '/uploadify/uploadify.swf',

         'uploader': '/ashx/upload.ashx',

         onUploadError: function (data) { alert(data); }

     });

 });

 using System;

 using System.Collections.Generic;

 using System.Linq;

 using System.Web;

 namespace JQ_uploadify.ashx

 {

     /// <summary>

     /// checkExisting 的摘要说明

     /// </summary>

     public class checkExisting : IHttpHandler

     {

         public void ProcessRequest(HttpContext context)

         {

             context.Response.ContentType = "text/plain";

             context.Response.Write("");

         }

         public bool IsReusable

         {

             get

             {

                 return false;

             }

         }

     }

 }

后台暂时测试文件，以后完善

debug：调试必备，可以看到上传的详细信息。

SWFUpload Instance Info

fileObjName：设置一个名字，在服务器端根据该名字来取上传文件的数据。默认值Filedata，老版本fileDataName

fileSizeLimit：上传文件的大小限制（HTML也会对上传文件大小进行限制，好像是4M），默认单位KB，接受单位：B、KB、MB、GB。

fileTypeDesc：可选的描述文件。这个字符串出现在浏览文件对话框的文件类型下拉列表中。

fileTypeExts：允许扩展的列表,可以上传。手动输入文件名称可以绕过这种级别的安全,所以你应该检查你的服务器端脚本文件类型。分号分隔的多个扩展应该予以运行(即"*.jpg;*.png;*.gif")。这只是对上传文件的类型做了限制，服务器端必须进行校验。

formData：附加参数的提交方式，json格式提交，后台request获取。如果是想动态提交，可以在onUploadStart事件对应的方法中附加参数。

 $(function () {

     $("#upload").uploadify({

         'formData': { 'someKey': 'someValue', 'someOtherKey': 1 },

         'swf': '/uploadify/uploadify.swf',

         'uploader': '/ashx/upload.ashx',

         'onUploadStart': function (file) {

             $("#upload").uploadify("settings", "someOtherKey", 2);

         }

     });

 });

 public void ProcessRequest(HttpContext context)

 {

     context.Response.ContentType = "text/plain";

     string path = context.Request["upload"].ToString();

     string s1 = context.Request["someKey"].ToString();

     string s2 = context.Request["someOtherKey"].ToString();

     string s3 = context.Request["someOtherKey"].ToString();

     DirectoryInfo dir = new DirectoryInfo(path);

     context.Response.Write(dir.FullName);
