Need a basename function in Javascript

Question

I need a short basename function (one-liner ?) for Javascript:

basename(\"/a/folder/file.a.ext\") -> \"file.a\"
basename(\"/a/folder/file.ext\") -> \"f         


        

Answer 1

Maybe try to use existing packages if you can. http://nodejs.org/api/path.html

var path = require('path');
var str = '/path/to/file/test.html'

var fileNameStringWithoutExtention = path.basename(str, '.html');
// returns 'test'

// let path determine the extension
var fileNameStringWithoutExtention = path.basename(str, path.extname(str));
// returns 'test'

Other examples:

var pathString = path.dirname(str);
var fileNameStringWithExtention = path.basename(str);
var fullPathAndFileNameString = path.join(pathString, fileNameString);
