How to get basename of a file name?

[Wild Pete]

Is there an equivalent to a "basename" in javascript
that returns the last part of a file name?
For example, given "C:\My Documents\test.txt" and
"/usr/local/test.txt", both should return "test.txt".
Any help would be appreciated.

Backslashes in strings should be escaped with another backslash, so
use "C:\\My Documents\\test.txt" instead. Then run this regex:

var a="/usr/local/test.txt";
var b=a.match(/[\/|\\]([^\\\/]+)$/);
alert( b[1] );
