  1.   

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
    <HTML>
    <HEAD>
    <title>ThorUploadFlash</title>
    <meta name="GENERATOR" Content="Microsoft Visual Studio .NET 7.1">
    <meta name="CODE_LANGUAGE" Content="C#">

    <script language="javascript">
    //获取对象
    function init()
    {
    document.Form1.reset();
    var BrowFile=document.getElementById("ThorUploadFileControl");}
    //选择一个文件
    function BrowAFile()
    {
    document.Form1.reset();var BrowFile=document.getElementById("ThorUploadFileControl");
    BrowFile.onchange=FileSelectChange;
    BrowFile.click();
    }
    //当已经选择了一个文件时
    function FileSelectChange()
    {
    var BrowFile=document.getElementById("ThorUploadFileControl");
    window.alert(BrowFile.value);
    //需要传递消息给FLASH
    }
    //开始上传
    function StartUpload()
    {
    //获取表单
    var BrowFile=document.getElementById("ThorUploadFileControl");
    BrowFile.onchange=null;
    document.Form1.action="saveuploadfile.aspx";
    document.Form1.submit();
    }
    </script>
    </HEAD>
    <body onload="init()"> 
    <a href="JavaScript:BrowAFile()">SelectFileName</a>

    <a href="JavaScript:StartUpload()">StartUpload</a> <form name="Form1"  id="Form1" enctype="multipart/form-data" action="POST">

    <INPUT id="button1" name="button1" type="submit" value="submit" > 
    </form></body>
    </HTML>
      

  2.   


    调用document.Form1.submit();
      

  3.   

    我把代码简化一下贴上来:
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
    <HTML>
    <HEAD>
    <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
    <title>ThorUploadFlash</title>
    <script language="javascript">function init()
    {
    document.Form1.reset();}function BrowAFile()
    {
    document.Form1.reset();var BrowFile=document.getElementById("ThorUploadFileControl");
    BrowFile.click();
    }function StartUpload()
    {
    document.Form1.submit();
    }
    </script>
    </HEAD>
    <body onload="init()"> 
    <a href="JavaScript:BrowAFile()">SelectFileName</a> 
    |
    <a href="JavaScript:StartUpload()">StartUpload</a> <form name="Form1"  id="Form1" enctype="multipart/form-data" action="POST" action="up.php">
    <INPUT id="ThorUploadFileControl" type="file" name="ThorUploadFileControl">
    <INPUT id="button1" name="button1" type="submit" value="submit" > 
    </form></body>
    </HTML>

    哦，有个地方敲错了<form name="Form1"  id="Form1" enctype="multipart/form-data" method="POST" action="up.php">谁帮我看一下这段代码应该怎么写？
