Make a JavaScript array from URL

Question

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=450x45         


        

Answer 1

the above function URLToArray is not working when url string has elem[]=23&elem[]=56.. see below the adapted function... hope it is working - not 100% tested

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

          //check we have an array here - add array numeric indexes so the key elem[] is not identical.
          if(endsWith(decodeURIComponent(pair[0]), '[]') ) {
              var arrName = decodeURIComponent(pair[0]).substring(0, decodeURIComponent(pair[0]).length - 2);
              if(!(arrName in arr)) {
                  arr.push(arrName);
                  arr[arrName] = [];
              }

              arr[arrName].push(decodeURIComponent(pair[1]));
              request[arrName] = arr[arrName];
          } else {
            request[decodeURIComponent(pair[0])] = decodeURIComponent(pair[1]);
          }
        }
        return request;
    }

where endWith is taken from here

function endsWith(str, suffix) {
    return str.indexOf(suffix, str.length - suffix.length) !== -1;
}
