hi...

i got this filename test.txt with the location of c:\testfolder\test.txt

i can get the full path name from the upload object. But i want to extract only the filename.(test.txt)

i tried using the split command but it gives me error when i run the javascript.
Error: object expected.

try using lastIndexOf(), and substring in combination.
fileName = filePath.substring(filePath.lastIndexOf("\\"));

Hi.. this method doesnt work.

i tried the following script:

var path=document.form.file.value;
var fname=path.substring(path.lastIndexOf("\\"));
alert(fname);

It gives me error:Object expected

Your problem lies here:
document.form.file.value

you have named your form as form, but form is treated as keyword in javascript, so change name of your form to frm or abcForm or anything you like (which is not a keyword), then your code will run smoothly.

Hi thanks for the reply.

document.upload_frm.file.value

change the name of file element too.
see whatever you give type to input elements those all are treated specially. so you shouldn't use them as names. (for example, text, file, submit, button, radio, etc..)

Ok thanks... Your code is using the "\\" separator for the file path. It doesnt work when the filepath have "\" as the separator. eg. C:\abc\xyz.txt

Any idea how to do that?

<script language="javascript" type="text/javascript">

function alertFileName()

{

dear "\\" is a single character, don't get confused due to that. see the example I gave you for file element.
