javascript - Get value of an array based on priority -

-

i have object array based on priority need form object array. below code tried

var data_res = [{    "action_type": "create",    "execution_type": "n_execution"    },     { "action_type": "create",   "execution_type": "r_pre_execution"    } ]; var arr =  ["r_pre_execution", "s_pre_execution", "n_execution"]; (var = 0; < data_res.length; i++) { (var temp in arr) {     if (data_res[i].rule_execution_type.indexof(arr[temp])>-1) {         console.log("data")         console.log(json.stringify(data_res[temp]))     } }

the output i'm getting is

data undefined data {"action_type":"create","execution_type":"n_execution"}

i want data based on array arr. first r_pre_execution data must formed s_pre_execution , n_pre_execution, don't know i'm going wrong.

it looks want sort data_res according order given arr.

var data_res = [{      "action_type": "create",      "execution_type": "n_execution"  }, {        "action_type": "create",      "execution_type": "r_pre_execution"  }]    var arr = ["r_pre_execution", "s_pre_execution", "n_execution"];    data_res.sort(function(a, b) {    var akey = arr.indexof(a.execution_type);    var bkey = arr.indexof(b.execution_type);      return akey - bkey;  });    document.write("<pre>" + json.stringify(data_res,0,3));
