Question

I need get from string, piece after last \ or /, that is from this string C:\fake\path\some.jpg result must be some.jpg

I tried this:

var str = "C:\fake\path\some.jpg";
var newstr = str.replace(/[^\\\/]+$/, "");
alert(newstr);

but not works, what is right regex for this?

Answer 1

You don't need a regex to do it, this should work:

var newstr = str.substring(Math.max(str.lastIndexOf("\\"), str.lastIndexOf("/")) + 1);
