代码分为以下部分:

demo.php - 上传过程处理

PLAIN TEXTPHP:

<?php
 
include 'UploadPRogressMeter.class.php';
 
$fileWidget = new UploadProgressMeter();
 
if ($fileWidget->uploadComplete()) {
　　　  // 上传完毕的时候,从iframe发送一个js到主窗口表示一切ok
　　　  echo $fileWidget->finalStatus();
 
　　　  // 处理上传后的文件...
 
　　　  exit;
}
?>

demoserver.php - Ajax的服务端js,使用Pear:HTML_AJAX,直接调用UploadProgressMeterStatus类

PLAIN TEXTHTML:

<script src="http://www.ooso.net/demoserver.php?client=main,request,httpclient,dispatcher,json,util" type="text/javascript"></script>
<script src="http://www.ooso.net/demoserver.php?stub=UploadProgressMeterStatus" type="text/Javascript"></script>
<?php echo $fileWidget->renderIncludeJs(); ?>

进度条的样式表

PLAIN TEXTCSS:

.progressBar {
  position: relative;
  padding: 2px;
  width: 300px;
  height: 40px;
  font-size: 14px;
}
.progressBar .background {
  border: solid 1px black;
  width: 270px;
  height: 20px;
}
.progressBar .bar {
  position: relative;
  background-color: blue;
  width: 0px;
  height: 20px;
}

表单部分

PLAIN TEXTHTML:

<form action="demo.php" method="post" enctype="multipart/form-data">renderFormExtra(); ?>>
<?php echo $fileWidget->renderHidden(); ?></form><form action="demo.php" method="post" enctype="multipart/form-data"><label>Select File: </label>
<div><?php echo $fileWidget->render(); ?>
<?php echo $fileWidget->renderProgressBar(); ?></div>
</form>
