javascript - Simplest way to convert a JSON object to a newly structured JSON object? -

i've got json object structured this:

{     "xaxis": [         "foo",         "bar",         "baz"     ],     "yaxis": [         333,         992,         1365     ] } 

from i'd create json object stuctured this:

{      "piegraph": [         ["foo",333],          ["bar",992],          ["baz",1365]     ]  } 

doing conversion in client-side javascript save me additional development , server round-trip fetch same data.

i can employ jquery library if help.

assuming first json string parsed object, have iterate on elements of of 2 arrays, build result:

var result = { piegraph: [] }; // initialize piegraph empty array  var l = obj.xaxis.length; while(l--) {   result.piegraph[l] = [ obj.xaxis[l], obj.yaxis[l] ]; }  // result this: // {"piegraph":[["foo",333],["bar",992],["baz",1365]]} 

no libraries needed, plain sequential loop. ;)
