Will this help? Watch for word-wrap.

<html>
<head>
<title>show.htm </title>
<script type="text/javascript">
function showfile() {
var pathname = location.pathna me;
var filename =
pathname.substr (pathname.lastI ndexOf("\\")+1, pathname.length );
alert(filename) ;
}
function showpath() {
var pathname = location.pathna me;
pathname = pathname.substr (1,pathname.len gth);
alert(pathname) ;
}
function showimage(that) {
alert(that.name );
}
</script>
</head>
<body>
<input type="button" value="Path+Fil e" onclick="showpa th()">

Re: javascript for capturing filename

Wow that solved my problem to the gr8 extent.

What I wanted exactly is that the script function should only pick the
primary name of the filename. Example.. if the file name is we1234.xyz
The function should pick we1234 and display on alert.

Pls help

This is redundant.
substr(startInd ex [,endIndex]).
endIndex is optional.
If endIndex is omitted, the substr goes to the end.

To get rid of your extention try this.
filename = pathname.substr (pathname.lastI ndexOf("\\")+1,
pathname.lastIn dexOf("."));

I don't remember off hand if substr includes the character at lastIndex or
not. If so, subtract one from the endIndex argument.
filename = pathname.substr (pathname.lastI ndexOf("\\")+1,
pathname.lastIn dexOf(".")-1);

Re: javascript for capturing filename

this has solved my problem. Either when we do alert or pass the result
to some div or span, it shows the primary name of the filename.

function showfile(that) {
var pathname = that.src;
var filename =
pathname.substr (pathname.lastI ndexOf("/")+1,pathname.l ength);
document.getEle mentById("disp" ).innerText = filename;

Thanks for your help

The prev ex. solved the problem, with some changes done.
But still I can have the filename as we1234.xyz & not as we1234, what
I want to achieve. Actually I want to give the primary part of
filename as the name of the picture, so that I donr have to put in the
picture name again n again for 1000's of them. So i found the result
thru

var filename = pathname.substr (pathname.lastI ndexOf("/")+1,pathname.l ength);
document.getEle mentById("disp" ).innerText = filename;

this gives filename(primar y.ext), but I want only primary name.
thanks and waiting for reply

var filename = pathname.split( ".");
document.getEle mentById("disp" ).innerHTML = filename[filename.length-1]

function showfile(that) {
var pathname = that.src;
var filename =
pathname.substr (pathname.lastI ndexOf("/")+1,pathname.l ength);
var filename = filename.substr (filename,filen ame.lastIndexOf ("."));
document.getEle mentById("disp" ).innerText = filename;
}

works with "lulu.lili_lolo .jpg"

var filename = pathname.split( ".");
document.getEle mentById("disp" ).innerHTML = filename[filename.length-2]

"length-2"

var filename = pathname.split( "/");
document.getEle mentById("disp" ).innerHTML =
filename[filename.length-1].split(".")[0]

Disregard earlier answer.

Were you waiting for me to respond?

Here's a variation of what I posted before.

Watch for word-wrap.

<html>
<head>
<title>show.htm </title>
<script type="text/javascript">
function showfile() {
var pathname = location.pathna me;
var filename =
pathname.substr (pathname.lastI ndexOf("\\")+1, pathname.length );
alert(filename) ;
}
function showpath() {
var pathname = location.pathna me;
pathname = pathname.substr (1,pathname.len gth);
alert(pathname) ;
}
function showpref() {
var pathname = location.pathna me;
var filename =
pathname.substr (pathname.lastI ndexOf("\\")+1, pathname.length );
filename = filename.substr (0,filename.ind exOf("."))
alert(filename) ;
}
function showimage(that) {
alert(that.name );
}
</script>
</head>
<body>
<input type="button" value="Path+Fil e" onclick="showpa th()">
<input type="button" value="File Only" onclick="showfi le()">
<input type="button" value="File Pref" onclick="showpr ef()">
