Javascript (split) returns undefined, is there a way to return false if not true

[shortysbest]

I am building a hash navigation system for my website, but this problem is something I find with everything in javascript.

For this particular problem what I'm doing is splitting the hash url to get different data from it, the problem is when there are levels of the url not there instead of returning nothing, it returns "undefined" which goes into the spot the real data should have gone had there been data present.

 

example URL scenarios:

www.mysite.com/#/home

www.mysite.com/#/user/2

www.mysite.com/#/user/2/info

www.mysite.com/#/user/2/photos/album

www.mysite.com/#/user/2/photos/album/922

 

and it could just keep going on.

 

Here is the code I am using at the moment:

var hash_value = event.value; //would be /user/2/info   (or whatever the URL might be as shown above)

var uri = hash_value.split("/");
var page = uri[1];
var user_id = uri[2];
var page2 = uri[3];

 

That code works perfect if "user" "2" and "info" are all there, however if it were to be: "/user/2"

var page2 would be "undefined", I need it to just return blank ""

 

 

Any way I could do this?

var uri = hash_value.split("/");
var page = uri[1] ? uri[1] : '';
var user_id = uri[2] ? uri[2] : '';
var page2 = uri[3] ? uri[3] : '';

Ahhh I completely forgot about that, I have used that in the past. Been on break from coding haha, thank you.
