Greetings...
I'm new to Perl, and need help writing a script that will tell me the file size of a file I wish to upload via an html form before I actually upload it. The below script is an activex example of what I want to do. I just don't want to use activex for my project. Thanks...
<html>
<head>
<title>File System Object Example</title>
<script language="javascript">
<!--//
var oFileSystem;
oFileSystem = new ActiveXObject("Scripting.FileSystemObject");
function getFile(sFilePath){
frm.display.value = oFileSystem.GetFile(sFilePath).Size;
}
</script>
</HEAD>
<BODY>
<b>Select the File you would like to get the size of</b>
<form name="frm">
<input type="file" name="filPath" onchange="getFile(this.value)">
<input type="text" name="display">
</form>
</body>
</html>

as fas as I know it's not possible with just perl. You will need to use something client side to get the file size and load that value in a form field and check the value of that form field. Maybe someone else will know something I am not aware of.
Code:
It depends whether your web page is LOCAL...
You only have client-side functionality until submission

or REMOTE...
You have server-side functionality that you can make use of

You will be able to get the file size - however, it might be a bit awkwardKind Regards
