从多级JSON对象中选择性地提取数据

Question

I have a multi-level JSON object which is contains an array of 143 other objects.

Running console.log(obj) on this object displays:

0: Object
  ActFTEs: 0.00
  Actual: 11111
  Bud_Month: "October"
  FY_CD: 2013
  Mission_Name: "RST"
__proto__: Object
1: Object
  ActFTEs: 0.00
  Actual: 10000
  Bud_Month: "FY Total"
  FY_CD: 2013
  Mission_Name: "RST"

etc.... through all 143 objects. However, the name/value pair Mission_Name:"RST" is only prevalent in the first n objects.

For example, obj 43 contains:

43: Object
   ActFTEs: 0.00
   Actual: 10000
   Bud_Month: "FY Total"
   FY_CD: 2013
   Mission_Name: "VAO"

I have created the following function, but this still returns the full range of 143 values for the name/value pair related to "Bud_Month".

function get_dataArray() {
 var arr = [];
 var i= 0;
 for (i=0;i<jsonobj.row.length;i++) {   
    if (jsonobj.row[i][name]="RST") {
         arr[i] = jsonobj.row[i]["Bud_Month"];
    }    
 } 
 console.log(arr);
 return arr;
}

This returns:

["October", "FY Total", "December", "January", "February", "March", "April", "May", "June", "July", "August", "September", "FY Total", "October", "November", "December", "January", "February", "March", "April", "May", "June", "July", "August", "September", "November", "October", "November", "December", "January", "February", "March", "April", "May", "June", "July", "August", "September", "FY Total", "October", "FY Total", "December", "January", "February", "March", "April", "May", "June", "July", "August", "September", "FY Total", "October", "November", "December", "January", "February", "March", "April", "May", "June", "July", "August", "September", "November", "October", "FY Total", "December", "January", "February", "March", "April", "May", "June", "July", "August", "September", "FY Total", "October", "November", "December", "January", "February", "March", "April", "May", "June", "July", "August", "September", "November", "October", "FY Total", "December", "January", "February", "March", "April", "May", "June"…]

Does anyone have any advice for how to return the value for "Bud_Month" only in objects containing the name/value pair of Mission_Name:"RST" ?

Answer 1

if (jsonobj.row[i][name]="HST") {
     arr[i] = jsonobj.row[i]["Bud_Month"];
}   

Should probably be:

if (jsonobj.row[i][name]=="RST") {
     arr[i] = jsonobj.row[i]["Bud_Month"];
}
