以特定格式转换JSON格式

Question

I have JSON object like

countryMap = Object {KE: 10, BR: 9, NP: 7}

Now I want it in form like

[
      {
          "code": "KE",
          "value": 10
      },
      {
          "code": "BR",
          "value": 9
      },
      {
          "code": "NP",
          "value": 7
      }

];

What I tried is

$.each(countryMap, function(key, value){
        item = {};
        item ["code"] = key;
        item ["value"] = value;
        totalCountries+=1;
        jsonObj.push(item);
}); 

But what I am getting is

    [
      {
          "code": "KE"
          "value": 10
      },
      {
          "code": "BR"
          "value": 9
      },
      {
          "code": "NP"
          "value": 7
      }

];

Note that missing comma after code value.

How do I achieve exact format which I want?

Try with this..

 countryMap = {KE: 10, BR: 9, NP: 7}; var jsonObj=[]; $.each(countryMap, function(key, val){ jsonObj.push({code:key,value:val}); }); alert(JSON.stringify(jsonObj));

You should try this:

$.each(countryMap, function(key, value){
   item = {"code": key, "value": value};
   totalCountries+=1;
   jsonObj.push(item);
});
