Q:

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

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!

A:

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