JSP - input file, get fileName

[thesti]

hi,

i have this form in my .html file

<form method="post" action="test.jsp">
            <table width="100%">
                <tr>
                    <td>Attachment File</td>
                    <td><input type="file" name="attachment"></td>
                </tr>
                <tr>
                    <td></td>
                    <td><input type="submit" value="Update"><input type="reset"></td>
                </tr>
            </table>            
            </form>
 

now, i don't want to upload the file chosen to the server, i only want to get the filename of the chosen file by the user.

how can i do that?

thanks in advance

I'll move this to the Javascript forum.

Use this code it will give you the file name.But at first give Id to the field i.e where you are taking the input file name

as [HTML]<td><input type="file" id ="attachment" name="attachment"></td>[/HTML]

function getTheFileName(){alert();
 
var pathname=document.getElementById("attachment").value;
alert(pathname);
 
 
 
 
var partOfPath=pathname.split('\\');
 
var lengthOfPath=partOfPath.length;
var fileName=partOfPath[lengthOfPath-1];
alert(fileName);
 
}

does that code work in firefox 3?

there is no path on file input.value in ff3, so the hard-coded -1 makes me skeptical.

If it works at all in any browser I would think it would be a security issue. Most browser security models do not allow JavaScript to access the file input tag to prevent local file system information from being sent back to the server. Returning just the file name and not the path I guess is not going to be a problem.

actually, firefox 3 gives javascript full binary or text access to data in the file inputs...

all other browsers do not give this access, but they do give the full path.
