Make a JavaScript array from URL

I need to make a Javascript array from URL, eg:

turn this:

http://maps.google.com/maps/api/staticmap?center=Baker Street 221b, London&size=450x450&markers=Baker Street 221b, London&sensor=false

Into something like:

array['center'] = Baker Street 221b, London
array['size'] = 450x450
// and so on...

I need to make this serializaion/unserialization work both ways (url to array and array to the part of the url). Are there some built-in functions that do this?

Thanks in advance!

Answer

URL to array: (adapted from my answer here)

function URLToArray(url) {
    var request = {};
    var pairs = url.substring(url.indexOf('?') + 1).split('&');
    for (var i = 0; i < pairs.length; i++) {
        if(!pairs[i])
            continue;
        var pair = pairs[i].split('=');
        request[decodeURIComponent(pair[0])] = decodeURIComponent(pair[1]);
     }

     return request;
}

Array to URL:

function ArrayToURL(array) {
  var pairs = [];
  for (var key in array)
    if (array.hasOwnProperty(key))


      pairs.push(encodeURIComponent(key) + '=' + encodeURIComponent(array[key]));
  return pairs.join('&');
}
