Nested JSON objects - do I have to use arrays for everything

Question

Is there any way to have nested objects in JSON so I don t have to make arrays out of everything  For my object to be parsed without error I seem to need a structure like this     data     stuff          onetype              id  1  name   John Doe              id  2  name   Don Joeh                 othertype              id  2  company   ACME               otherstuff          thing             1 42   2 2                If I fetch this object into a variable called  result  I have to access the nested objects like this    result data 0  stuff 0  onetype 0    and  result data 1  otherstuff 0  thing 0    This seems clumsy and redundant to me  if possible I would prefer   result stuff onetype 0    and  result otherstuff thing   But how can I use the object keys directly when everything is an array  To my confused and uneducated mind something like this would seem more appropriate     data         stuff             onetype                  id  1  name                      id  2  name                            othertype                  id  2  xyz    -2 0 2   n   Crab Nebula   t  0  c  0  d  5                         otherstuff             thing                 1 42   2 2                       I ve probably misunderstood something fundamental here  but I cannot get the jQuery parser  nor the native FF parser used by jQuery 1 4  to accept the second style object  If anyone can enlighten me it would be gratefully appreciated

You have too many redundant nested arrays inside your jSON data, but it is possible to retrieve the information. Though like others have said you might want to clean it up.

use each() wrap within another each() until the last array.

for result.data[0].stuff[0].onetype[0] in jQuery you could do the following:

`

$.each(data.result.data, function(index0, v) {
    $.each(v, function (index1, w) {
        $.each(w, function (index2, x) {
            alert(x.id);
        });
    });

});

`

You don t need to use arrays   JSON values can be arrays  objects  or primitives  numbers or strings    You can write JSON like this           stuff              onetype                   id  1  name   John Doe                  id  2  name   Don Joeh                       othertype     id  2  company   ACME                otherstuff              thing     1 42   2 2              You can use it like this   obj stuff onetype 0  id obj stuff othertype id obj otherstuff thing 0  1     thing is a nested array or a 2-by-2 matrix                                I m not sure whether you intended to do that

Every object has to be named inside the parent object      data          stuff              onetype                    id   1   name                        id   2   name                            othertype                    id   2   xyz    -2  0  2    n    Crab Nebula    t   0   c   0   d   5                         otherstuff              thing                 1  42    2  2               So you cant declare an object like this   var obj    property1  property2     It has to be   var obj    property1   value   property2   value
