在javascript中输入完整文件名时如何获取文件路径？

我希望获得文件名的路径，就像输入字符串/storage/emulated/0/Pictures/时获得结果/storage/emulated/0/Pictures/Photo-2017-02-17-10-08-38_2271.JPG一样

如何使用javascript？谢谢

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

+1包括最后一个正斜杠。

试试看

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

尝试var path=filename.match/*[\/\\]/[1]||；将第二行替换为fullpath.substr0，fullpath.lastIndexOf'/'+1@GovindaRajbhar感谢您的观察。忘了更改伪造的变量名。

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