Simple question

[Simon]

How can i divide a string using javascript?
For example, i've got a textfield named "attach1", the value is: "
C:\Documents and Settings\Simon\Mijn documenten\calendaroptie.txt
"

So in javascript i start with:
var chk=document.TE.attach1.value
var filename= ?

Where filename must get the value of the last "slash" (calendaroptie.txt)

How do I do that?

Thanks,
Simon

how about this:

var filename=chk.substring(chk.lastIndexOf("\\"));

Ok thanks, but how do i recognize the last piece of the string?
I want to set a variable equal to the last "/". (This string can also be
variable).
I'm sorry, but I really don't know anything about javascript.
I would like it coded, all the way

Thanks..

Thanks,

It works, except for one thing, now the variable "filename" isn't equal to
"calendaroptie.txt" but to "/calendaroptie.txt"
Could you help me once more? (Remove the slash)

Please don't top-post, reply below trimmed quotes.

The suggested solution was:

var s = "/some/path/to/a/file"
var t = s.split('/');

so t is now an array of the bits of s split by '/'. To get the last
bit:

alert( t[t.length - 1] );

or, using a regular expression:

alert( s.replace(/^.*\//,'') );

I want to set a variable equal to the last "/". (This string can also be
variable).

Which makes me wonder what you are going to do with it.

I'm sorry, doesn't seem to work.

or, using a regular expression:

alert( s.replace(/^.*\//,'') );

window.alert(s.match(/[^\/]*$/)[0]);

is more efficient.

or, using a regular expression:
alert( s.replace(/^.*\//,'') );

window.alert(s.match(/[^\/]*$/)[0]);
is more efficient.

/[^\/]+$/.exec(s);

is even more so, since you don't have to test whether or not s is a
string (or that it is even defined, if you wrap it in a function).
