javascript - json getting attribute in position 0 -

so if have following json

{ "data": {     "sectionlist": {         "section124": [{                 "a": "test",                 "b": "test",                 "c": "test",                 "d": "test",                 "e": "test2013-04-14"             }, {                 "a": "test",                 "b": "test",                 "c": "test",                 "d": "test",                 "e": "test2013-04-14"             }         ]     },     "section00824": [         [{                 "a": "test",                 "b": "test",                 "c": "test",                 "d": "test",                 "e": "test2013-04-14"             }, {                 "a": "test",                 "b": "test",                 "c": "test",                 "d": "test",                 "e": "test2013-04-14"             }         ]     ] } 

}

and ajax on within code , have callback returns result need know first section called

i know can this:

return result.data.sectionlist.section124; 

but problem dont know name can change every time

i tried

return result.data.sectionlist.*; return result.data.sectionlist[0]; 

but not allowed

any ideas?

thanks

if have 1 section, can name doing object.keys(result.data.sectionlist)[0]. however, if have more 1 section , want first, can't result object since objects in javascript don't preserve key ordering.
