Not supproted multi-dimensional objects on jQuery.ajax options.data

[aiky]

options.data = {

a: 'a',
b: 'b',
c: {

d: 'd',
e: 'e'

}

}

POST:
a a
b b
c [object+Object]

What would you expect the result to be ?

[aiky]

I need to receive on server side:

array(

a=>'a',
b=>'b',
c=>array(

d=>'d',
e=>'e'

)

)

as realised in JsHttpRequest

You can do something like this though:

options.data = {
    a: 'a',
    b: 'b',
    c[d]: 'd',
    c[e]: 'e'
}

And on the server-side, the POST request would automatically see c as an array of values.

I do this to pass an array of checkboxes to a php script, the name of each input is something like "input_name[some_index]". Then in php, $_REQUESTinput_name? becomes an array where "some_index" becomes the key.

I do agree though that it should accept multi-dimensional objects as well though, it makes it much easier.

Yes, may to find some ways for emulating multi-dimensional objects. But would be most corretly to use multi-dimensional objects transparent by core level of jQuery as JSON is multi-dimensional data format and much using in AJAX interactions.

Ok. Next code translating multi-dimensional object to simple list and can be include to jQuery core for transparent using multi-dimensional objects:

var object2list = function(object, list, _key){
  if(!list) var list = {};
  for(var key in object){
    if(!_key) var _key_ = key;
    else var _key_ = _key + '[' + key + ']';
    if(typeof(object[key]) != 'object') list[_key_] = object[key];
    else list = object2list(object[key], list, _key_);
    object[key] = null;
  }
  return list;
}

Object must be Key/Value pairs. If value is an Array, jQuery serializes multiple values with same key i.e. {foo:["bar1", "bar2"]} becomes '&foo=bar1&foo=bar2'.
