I have a path and I am trying to pop off everything after the last /, so 'folder' in this case, leaving the newpath as C://local/drive/folder/.
I tried to pop off the last / using pop(), but can't get the first part of the path to be the new path:
var path = C://local/drive/folder/folder
var newpath = path.split("/").pop();
var newpath = newpath; //should be C://local/drive/folder/
.slice() instead of
var newpath = path.split("/").slice(0, -1).join("/");
If you also need the last part, then just use
.pop(), but first store the Array in a separate variable.
var parts = path.split("/"); var last = parts.pop(); var first = parts.join("/");
last has the last part, and
first has everything before the last part.
Another solution is to use
.lastIndexOf() on the string.
var idx = path.lastIndexOf("/"); var first = path.slice(0, idx); var last = path.slice(idx + 1);
