function - serialize()

//avantage comparé à la fonction .serialize() de JQuery?
//-> ça supporte tous les types d'input (email, range, number... etc)

function serialize(form) {
  var i, els = form.elements, r = "";

  for(i = 0; i < els.length; i++) {
    if(els[i].type != "submit" && els[i].type != "reset") {
      r += encodeURIComponent(els[i].name) + "=" + encodeURIComponent(els[i].value);
      if(i+1 != els.length && els[i+1].type != "submit" && els[i+1].type != "reset") {
        r += "&";
      }
    }
  }

  return r;
