How to split the ending of a file name using JavaScript

Question

How can I split the ending of a file, like for instance I want file01 instead of file01.xlsx

My written code:

var filename = $v('P40_UPLOAD').split('\\').pop().split('/').pop();

var s = $s("P40_NAME",filename);

s.split('.')[0];

Unfortunately it doens't work.

If dot is the separator in the filename, then why are you splitting on space? — Tim Biegeleisen, Jun 07 '18 at 07:16

If you know the length of the extension, you can use x.slice(0, -4) (where 4 is the three characters of the extension and the dot).

Try the following:

var file = "file01.xlsx";

var index = file.lastIndexOf(".");
 var filename = file.substring(0,index);
 console.log(filename);

Do this Regex:

var url = 'http://stackoverflow.com/file01.xlsx';
var filename = url.match( /([^\/]+)(?=\.\w+$)/ )[0];
console.log( filename )

Alternately, you can do this without regular expressions altogether, by finding the position of the last / and the last . using lastIndexOf and getting a substring between those points:

var url = 'http://stackoverflow.com/file01.xlsx';
var filename = url.substring(url.lastIndexOf( '/' ) + 1, url.lastIndexOf( '.' ));
console.log( filename )
