显示文件上传的进度条 [英] Displaying progressbar for file upload

问题描述

我需要创建一个应用程序，可以在其中添加要上传的文件。当我添加上传项目时，一个进度条应该与每个添加的项目一起显示。而当我点击文件上传时，每个文件上传文件的进度都应该反映在进度条上。进度应该使用像

  ..... 
 addEventListener（ProgressEvent.Progress，uploadProgressHandler）; 
 
 private function uploadProgressHandler（event：ProgressEvent）：void 
 {
 var numPerc：Number = Math.round（（Number（event.bytesLoaded）/ Number（event.bytesTotal） ）* 100）; 
 
 //this.progBar.validateNow（）; 
 
 ..... 
} 
  

任何人都可以提供帮帮我吗？

解决方案

看起来像这样：

I need to create an application where I can add files for upload. As I add items for upload, a progressbar should be displayed along with each item added. And when I click for file upload, the progress of file upload for each file should be reflected in the progress bar. The progress should use the function like

.....
addEventListener(ProgressEvent.Progress, uploadProgressHandler);

private function uploadProgressHandler(event:ProgressEvent):void
{
    var numPerc:Number = Math.round((Number(event.bytesLoaded) / Number(event.bytesTotal)) * 100);

    //this.progBar.validateNow();

    .....
}  

Can anyone provide help me out?
