Create a bit.ly URL by passing the URL you want shortened and preforming a function with it

jQuery_bitlyfi.js

function bitlyfi(url, func) {
	var defaults = {
		token: '',
		longUrl: url
	};
	// Build the URL to query
	var bitly = 'https://api-ssl.bitly.com/v3/shorten?' + '&access_token=' + defaults.token + '&longUrl=' + defaults.longUrl + '&format=json&callback=?';

	// Utilize the bit.ly API
	$.getJSON(bitly, function (results) {
		if (results.status_txt === 'OK') {
			return func(results.data.url);
		} else {
			return func(url);
		}
	});
}

//Example usage
$('a').click(function (e) {
    e.preventDefault();
    var href = $(this).attr('href');
    bitlyfi(href, function (bitlyfiedURL) {
        alert(bitlyfiedURL);
    });
});
