Decode value from URL using Javascript

Question

I am taking a parameter value from the URL which is as follows:

users%2F3

Where it should be users/3

How can I decode the value I am getting using Javascript?

I tried the following before:

var a = "users%2F3"; 
console.log(decodeURI(a));

But the log shows the same encoded value.

With the imaginatively named decodeURIComponent function. (See also the specification).

@MiguelMoura Yes, a completely different function (`decodeURI`) doesn't do the same thing as `decodeURIComponent`. – JJJ Sep 08 '16 at 15:00
Ah now I see what I was doing wrong. Thanks. – Miguel Moura Sep 08 '16 at 15:02

If you want you can create your own function like

function urldecode(str) { return decodeURIComponent((str+'').replace(/\+/g, '%20')); };

this will also replace the '+' from the decodeURI component into spaces
