jQuery on the fly URL shortener

Here is an example how to get a shortened URL with Bitly API and jQuery:

function get_short_url(long_url, login, api_key, func)
{
    $.getJSON(
        "http://api.bitly.com/v3/shorten?callback=?", 
        { 
            "format": "json",
            "apiKey": api_key,
            "login": login,
            "longUrl": long_url
        },
        function(response)
        {
            func(response.data.url);
        }
    );
}

The following code could be used to get a short URL:

/*
Sign up for Bitly account at
 https://bitly.com/a/sign_up

and upon completion visit
https://bitly.com/a/your_api_key/ 
to get "login" and "api_key" values
*/
var login = "LOGIN_HERE";
var api_key = "API_KEY_HERE";
var long_url = "http://www.kozlenko.info";

get_short_url(long_url, login, api_key, function(short_url) {
    console.log(short_url);
});
