在javascript中輸入完整文件名時如何獲取文件路徑？

Question

我希望獲取文件名的路徑，就像輸入字符串/storage/emulated/0/Pictures/Photo-2017-02-17-10-08-38_2271.JPG時獲得結果/storage/emulated/0/Pictures/ /storage/emulated/0/Pictures/Photo-2017-02-17-10-08-38_2271.JPG

我該如何使用JavaScript？ 謝謝！

Answer 1

嘗試

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

Answer 2

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

Answer 3

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

+1將包含最后一個正斜杠。
