javascript - remove everything before the last occurrence of a character

Question

I'm trying to perform the following action on a string :

• find the last occurrence of the character "/";
• remove everything before that character;
• return the remains of the string;

To be more explicit, let's say I have the following string :

var string = "/Roland/index.php"; // Which is a result of window.location.pathname

Now what I need to extract out of it is everything but the actual page, something like this :

var result = "index.php" // Which is what I need to be returned

Of course, that is just an example, because obviously I will have different pages, but the same principles apply.

I was wondering if someone could help me out with a solution for it. I tried the next actions but with no success :

var location = window.location.pathname;
var result = location.substring(location.lastIndexOf["/"]);

You have the right idea just replace the brackets with parentheses.

var string = "/Roland/index.php";
var result = string.substring(string.lastIndexOf("/") + 1);

Here is an example in jsfiddle and here is an explanation of the .lastIndexOf() method on the Mozilla Developer Network.
