先来看看效果图吧:

 

下面就是在as iframe里面加的代码.

import flash.net.FileReference;
import mx.controls.Alert;

var my_pb:mx.controls.ProgressBar;
var maxSize = 1000*1000*100; //文件大小限制:100M
//设置进度栏模式
my_pb.mode = "manual";
my_pb.label = "上传进度:%1%";
my_pb._visible=false
//进度栏增加前的最小数值
my_pb.minimum = 0;
// 进度栏停止前的最大值
my_pb.maximum = 100;
var increment_num:Number = my_pb.minimum;

var allTypes:Array = new Array();
var imageTypes:Object = new Object();
imageTypes.description = "Images (*.jpg, *.jpeg, *.gif, *.png)";
imageTypes.extension = "*.jpg; *.jpeg; *.gif; *.png";
allTypes.push(imageTypes);

//var textTypes:Object = new Object();
//textTypes.description = "Text Files (*.txt, *.rtf)";
//textTypes.extension = "*.txt;*.rtf";
//allTypes.push(textTypes);

var flvType:Object =new Object();
flvType.description ="flv Files (*.flv)";
flvType.extension ="*.flv";
allTypes.push(flvType);

var rmType:Object =new Object();
rmType.description ="rm Files (*.rm)";
rmType.extension ="*.rm";
allTypes.push(rmType);

// 定义警告确认后的动作。
var myClickHandler:Function = function (evt_obj:Object) {
if (evt_obj.detail == Alert.OK) {
trace("start stock app");
}
};

var listener:Object = new Object();

listener.onSelect = function(file:FileReference):Void {

//}
   if (file.size<=maxSize)
   {
     //strState.text = "您选择得文件:" + file.name + "n";
     btnUpload.enabled = true;
   }else
   {
     msg( "对不起您选择的文件太大!");
     btnUpload.enabled = false;
   }
}

listener.onCancel = function(file:FileReference):Void {
trace("onCancel");
}

listener.onOpen = function(file:FileReference):Void {
trace("onOpen: " + file.name);
}

   my_pb.setProgress ((bytesLoaded / bytesTotal) * 100, my_pb.maximum);
}

listener.onComplete = function(file:FileReference):Void {
trace("111111111111onComplete: " + file.name);
   //msg("上传完毕!");
   getURL ("Javascript: formsub ()");
}

listener.onHTTPError = function(file:FileReference):Void {

   msg("onSecurityError: " + file.name + " errorString: " + errorString);
}

var fileRef:FileReference = new FileReference();
fileRef.addListener(listener);
this.btnBrowse.onRelease = function () {
   fileRef.browse(allTypes);
};
//this.btnUpload.onRelease = function () {
  // if(!fileRef.upload("/upload.php")) {
//trace("Upload dialog failed to open.");
//}
   // 显示警告对话框。

//}
//fileUploadURL="/upload.php";
function scrubba() {
 if(fileUploadURL){
  my_pb._visible=!false;
  btnBrowse.enabled = false;
  if(!fileRef.upload(fileUploadURL)) {
   trace("Upload dialog failed to open.");
  }
  fileUploadURL='';
 }
  }
_root.onEnterFrame = scrubba;

function msg(msgtxt:String) {
   Alert.show(msgtxt, "消息", Alert.OK , this, myClickHandler, "stockIcon", Alert.OK);
}
