Creating an array in JavaScript from JSON file -

-

my json file:

[{"val0":"paul","val1":"jake","val2":null,"val3":"max"},  {"val0":"sam","val1":"tina","val2":"emily","val3":"hardwell"},  {"val0":"tom","val1":"julie","val2":null,"val3":"adi"}]

i want create array in javascript follows:

var dataset=[   ['paul','jake','null','max'],   ['sam','tina','emily','harwell'],   ['tom','julie','null','adi'] ];

i tried following code isn’t working. can please help?

$.getjson("filename.json", function(data) {   var items = [];   $.each(data, function(key, val) {     items.push(val);   });   // … });

i’m using array display purpose (using datatables), so, want create array in format.i'm using dataset array displaying in datatables follows:

var dataset = [     ['paul','jake','isha','mike','null','null','parth','tinker'],     ['tina','michael','null','blue','red','','emily','mina'] ];  $(document).ready(function() {     $('#demo').html( '<table cellpadding="0" cellspacing="0" border="0" class="display" id="example"></table>' );     $('#example').datatable( {         "data": dataset,         "columns": [             { "title": "name" },             { "title": "deadline" },             { "title": "additional fees" },             { "title": "requirements" },             { "title": "field" },             { "title": "award" },             { "title": "renewable requirements"},             { "title": "link" }         ]     } ); } );

a solution without jquery: 

var data = [          { "val0": "paul", "val1": "jake", "val2": null, "val3": "max" },          { "val0": "sam", "val1": "tina", "val2": "emily", "val3": "hardwell" },          { "val0": "tom", "val1": "julie", "val2": null, "val3": "adi" }      ],      dataset = data.reduce(function (r, a) {          var i, a0 = [];          (i in a) {              a0.push(a[i]);          }          r.push(a0);          return r;      }, []);  document.getelementbyid('out').innerhtml = json.stringify(dataset, null, 4);
<pre id="out"></pre>
