Question

我有以下脚本允许文件通过PHP脚本上传到我的Web服务器，但我希望将伪代码转换为纯动作脚本。此外，由于某种原因，我的进度条不会显示文件上传的实际进度。

以下是PHP代码：

<?php

$tempFile = $_FILES['Filedata']['tmp_name'];
$fileName = $_FILES['Filedata']['name'];
$fileSize = $_FILES['Filedata']['size'];

move_uploaded_file($tempFile, "./" . $fileName);

?>

以下是Adobe Flex代码：

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
               xmlns:s="library://ns.adobe.com/flex/spark"

               width="225" height="178" minWidth="955" minHeight="600">

    </fx:Declarations>

<fx:Script>
    <![CDATA[

        import flash.net.FileReference;
        public var fileRef:FileReference = new FileReference();
        public function uploadDialog(e:MouseEvent):void{
            errLabel.text="";
            var imgType:FileFilter = new FileFilter("Images (*.GIF,*.JPG,*.PNG)","*.gif;*.jpg;*.png");
            var filterArray:Array=new Array(imgType);
            fileRef.browse(filterArray);
            fileRef.addEventListener(Event.SELECT,fileSelect);
            fileRef.addEventListener(ProgressEvent.PROGRESS,fileProgress);
            fileRef.addEventListener(Event.COMPLETE,fileComplete);
        }

        public function fileSelect(e:Event):void{
            var fileURL:URLRequest = new URLRequest("upload.php");
            try
            {
                //filepath.text=fileRef.name;
                fileRef.upload(fileURL);
            }
            catch (err:Error)
            { 
                errLabel.text="Unable to Upload File.....";
            }
        }

        public function fileProgress(e:ProgressEvent):void
        {
            progBar.visible=true;
        }

        public function fileComplete(e:Event):void{

            errLabel.text="File Uploaded Sucessfully....."
            progBar.visible=false;

        }

Answer 1

选中此example：您必须设置maximum和minimum属性，并在fileProgress功能中致电setProgress

有两种方法可以将flex代码转换为纯as3：
*在flex-config.xml中设置<keep-generated-actionscript>true</keep-generated-actionscript> *重写代码而不使用mxml作为纯as3项目

Answer 2

这就是我在寻找有关进度条更新的内容。

private function progressHandler(event:ProgressEvent):void 
{ 
    pb.setProgress(event.bytesLoaded, event.bytesTotal); 
}

Adobe Flex到纯动作脚本。怎么样？
