Need regex to replace entire folderpath while preserving file name where last folder could by anything

Question

I need a regex that would replace something like this but leave the file name.

/folder1/folder2/folder3/anything/somefile.html

Also could someone show me how to implement this with replace method? Replacing the entire path match to empty string and again leaving the file and which would be anything.

Thanks in advance.

I wonder if it really is the purpose to have an answer on StackOverflow for every possible separator character... — trincot, May 28 '16 at 13:47

You can do it without regular expressions:

var filename = string.split('/').pop();
// "somefile.html"

@anubhava. The backticks are called string literals, and they don't need parentheses to execute the function. – Washington Guedes May 28 '16 at 13:57
Yes I know but are all browsers supporting them? – anubhava May 28 '16 at 14:01

I'd say modern browsers yes, but you are right, better to avoid them by now. – Washington Guedes May 28 '16 at 14:02

You can use .*\/.

. will match anything
* will repeat the previous zero or more times.
\/ is a literal slash (/). But needs to be escaped because it's part of the regex construct:

var str = '/folder1/folder2/folder3/anything/somefile.html';
str.replace(/.*\//, ''); // "somefile.html"

I updated my question. Would need to only replace the path without affecting the file. – Judson Terrell May 28 '16 at 13:39
@JudsonTerrell Isn't that was it does? – Andreas Louv May 28 '16 at 13:40
So you could have infinite levels with your solution it seems? – Judson Terrell May 28 '16 at 14:05
@JudsonTerrell The regex removes all up to and including the last slash. – Andreas Louv May 28 '16 at 14:08
