jquery - Knockout.js mapping plugin, accessing json nested multiple levels -

is possible knockout.js mapping plugin access json nested data or can find first level data?

if mapping plugin cannot access nested data there solution?

in example, "number" mapping correctly "duedate" not map.

// json nested data {    "level1":[       {          "level2":{             "duedate":"\/date(1362124800000)\/",             },          "number":5499       }, }  // here's data model - need map "duedate" observable. var viewmodel; $.getjson('/myjsondata', function (data) {     viewmodel = ko.mapping.fromjs(data);     ko.applybindings(viewmodel); }); 

are sure can't access duedate ? because in fiddle can.

// json nested data var data = {     "level1": [{         "level2": {             "duedate": "\/date(1362124800000)\/",         },             "number": 5499     }] }; var viewmodel = ko.mapping.fromjs(data); ko.applybindings(viewmodel);  var duedate = viewmodel.level1()[0].level2.duedate;  alert(typeof duedate);
