<body>
<input type="text" id="txt1" />
<input type="file" id="file1" />
<input type="button" id="btnUpload" value="Upload" />
<script type="text/javascript">
$(document).ready(function () {
//1.配置
$("#file1").uploadify({
swf: "/Scripts/uploadify/uploadify.swf",
uploader: "/Upload2.ashx",
fileTypeExts: "*.apk;*.zip;*.rar;*.7z",
fileSizeLimit: "10MB",
uploadLimit: 1,
auto: false,
multi: false,
onUploadStart: function () {
$("#file1").uploadify("settings", "formData", {
txt1: $("#txt1").val(),
t: (new Date()).getTime()
});
},
onUploadError : function(file, errorCode, errorMsg){
alert(file.name + "上传失败！" + errorCode + ":" + errorMsg);
},
onUploadSuccess: function (file, data) {
alert(file.name + "上传成功！");
}
});
//2.上传
$("#btnUpload").click(function () {
$("#file1").uploadify("upload");
});
});
</script>
</body>
</html>Upload.ashx：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace com.mzwu.www
{
public class Upload : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
JSONResult result = new JSONResult() { stat = -1, msg = "" };
try
{
HttpPostedFile file = context.Request.Files["Filedata"];//固定Filedata
file.SaveAs(context.Server.MapPath(file.FileName));
result.stat = 1;
}
catch (Exception ex)
{
result.msg = ex.Message;
}
context.Response.Write(result.ToString());
}
public bool IsReusable
{
get
{
return false;
}
}
}
public class JSONResult
{
public int stat { get; set; }
public string msg { get; set; }
public override string ToString()
{
return string.Format("{{\"stat\":{0},\"msg\":\"{1}\"}}", stat, msg);
}
}
}
上边方法的优点是参数和文件能一起上传到服务器，当页面只上传一个文件时处理起来比较简单，若要上传多个文件则不能用这个方法，因为Uploadify每次只能上传一个文件，每传一个文件参数都会提交一次，这时，参数和文件最好分开传：
<script type="text/javascript">
$(document).ready(function () {
//1.配置
$("#file1").uploadify({
swf: "/Scripts/uploadify/uploadify.swf",
uploader: "/Upload.ashx",
auto: false,
onQueueComplete: function (queueData) {
if (queueData.uploadsErrored == 0) {
//全部文件上传完成，这边单独提交参数
}
}
});
//2.上传
$("#btnUpload").click(function () {
$("#file1").uploadify("upload", "*");
});
});
</script>上面两个方法表单提交都依赖于文件上传，所以，当文件上传是可选时，上面两个方法都不能用，这时可参见《同一页面多个Uploadify实例+表单提交示例》。
以上代码在Uploadify v3.2.1测试通过。
