Dynamically create and delete JavaScript associative array key and values

I'm using jQuery 1.6

I'm not so good on JavaScript and I need to dynamically create an array having 2 dynamic parameters: json.id and json.name.

the array creation should result in :

[

[json.id]
         [ 
           json.name,
             开发者_如何学JAVAjson.name,
              json.name,
                etc .....
         ]
[json.id]
          [
           json.name, 
             json.name,
               json.name,
                  etc ....
         ]
etc ...
]

Then I need to be able to delete a json.id or a json.id json.name ....

Is there anyone can show me how to do this with all browser's support?

thx [EDITED]

the logic is this: (hoping it's clear :P )

    //first ajax call result:
    [{json.id_parent:json.name,json.id_parent:json.name,json.id_parent:json.name, etc..}]

    //second ajax call results passing the json.id_parent:
    [{json.id_parent_child:json.name,json.id_parent_child:json.name,json.id_parent_child:json.name,etc...}]
    //now for each call = id_parent create an associative array: 

{ 
id_parent:{id_parent_child,id_parent_child,etc ....},
id_parent:{id_parent_child,id_parent_child,etc ....},
etc...
}

    var myJson = {'id39':{'name':'Jesus','age':33}};
    var idDel = 'id39';
    delete myJson[idDel];// delete the complete reference with id
    var propDel = 'name';
    delete myJson[idDel][propDel];// delete only the property 'name' of the reference with id
// parsing complete json
    $.each(myJson, function(key, obj){// parse objects
      if(condition){
        delete myJson[key];// delete reference
      }
      $.each(obj, function(propName, val){// parse properties
        if(condition){
          delete obj[propName];// delete property
        }
      }
    });

Note, this sample assume you used json objects instead arrays so it is much easier and faster to remove sub objects or properties...
