Javascript代码

<script type="text/javascript">
function getFileSize(filePath)
{
var fso = new ActiveXObject("Scripting.FileSystemObject");
alert("文件大小为："+fso.GetFile(filePath).size);
}
</script>
<body>
<INPUT TYPE="file" NAME="file" SIZE="30" onchange="getFileSize(this.value);">
</body>

<script type="text/javascript"> function getFileSize(filePath) { var fso = new ActiveXObject("Scripting.FileSystemObject"); alert("文件大小为："+fso.GetFile(filePath).size); } </script> <body> <INPUT TYPE="file" NAME="file" SIZE="30" onchange="getFileSize(this.value);"> </body>

不推荐，也不多说

src，dynsrc，start，alt，controls，loop，loopdelay，hspace，vspace....

fileCreatedDate、fileModifiedDate、fileSize、fileUpdatedDate、filters...

Javascript代码

<script type="text/javascript">
function getFileSize(filePath)
{
var image=new Image();
image.dynsrc=filePath;
alert(image.fileSize);
}
</script>
<body>
<INPUT TYPE="file" NAME="file" SIZE="30" onchange="getFileSize(this.value)">
</body>

<script type="text/javascript"> function getFileSize(filePath) { var image=new Image(); image.dynsrc=filePath; alert(image.fileSize); } </script> <body> <INPUT TYPE="file" NAME="file" SIZE="30" onchange="getFileSize(this.value)"> </body>

推荐，没的说
