[rnd me]

here is one way:

function ob2url(ob){
  var buffer=[], param, enc=encodeURIComponent;
  for(param in ob){if(ob.hasOwnProperty(param)&& !ob[param].call){
    buffer[buffer.length]= enc(param)+"="+enc(ob[param]);
  }}//next own
 return buffer.join("&");
}



//myData= <? echo json_encode($data); ?> ;
myData={"task": "getuniqueid", "id": 3}; //for demo

$.ajax({
url: '../resources/ajax.api.php?'+ob2url(myData),
success: function(data)
{
var task = data.task;
var id = data.id; 

}
