我在javascript中输入完整文件名时如何获取文件路径？

Question

我希望得到文件名的路径，就像在输入字符串/storage/emulated/0/Pictures/时得到结果/storage/emulated/0/Pictures/Photo-2017-02-17-10-08-38_2271.JPG

我该怎么做javascript？谢谢！

Answer 1

尝试

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包含最后一个正斜杠。
