How to get file path when I input a full filename in javascript?

Question

I hope to get the path of a filename, just like get the result /storage/emulated/0/Pictures/ when I input the string /storage/emulated/0/Pictures/Photo-2017-02-17-10-08-38_2271.JPG

How can I do in javascript? Thanks!

try var path = filename.match(/(.*)[\/\\]/)[1]||'';

Try

var fullpath = "/storage/emulated/0/Pictures/Photo-2017-02-17-10-08-38_2271.JPG"
var pathWithoutFileName = fullpath.substr(0, fullpath.lastIndexOf('/') + 1);

var x = "/storage/emulated/0/Pictures/Photo-2017-02-17-10-08-38_2271.JPG"
var path = x.substr(0,x.lastIndexOf('/'));

var fullpath = "/storage/emulated/0/Pictures/Photo-2017-02-17-10-08-38_2271.JPG"
var path = fullpath.substr(0, fullpath.lastIndexOf('/') + 1);

The +1 is to include the last forward slash.

replace your second line as fullpath.substr(0, fullpath.lastIndexOf('/') + 1);

@GovindaRajbhar thanks for the observation. Had forgotten to alter the bogus variable names.
