You could do it with split(), pop() and replace()...

var filename = x.split('\\').pop().replace(/\..+$/, '');

jsFiddle.

You could also use a single regex...

var filename = x.replace(/.*\\|\..*$/g, '');

jsFiddle.

Ensure you escape the \ in your string literal too.

Working like a charm :-) Very thanks. I am very poor in regular expressions that is why I have asked for help.

You can use: "[^\\]*$"

but why not using regular javascript functions like indexOf() etc.

"[^\\]$" will match the very last character of the extension. He appears to not want the extension, and he does want more than one letter.

for the first problem you are correct it was a typo, and I fixed it, as for the second my bad I thought he needed the filename
