Question

这是我的结果数组，现在我想添加额外的键以及当前键。尝试过。推送不是功能

aa[0]['new_key'] = 'blah';    // is not working

我的数组看起来像。

 var aa =  [
        {
          "main": "56d940bb2b5916181d0906e2",
          "current": 6544
        }
      ]

我原来的代码是使用mongoDB查询。

connection.modal.find( { 'user_id' : user_id }, { 'abc.def' : true}, function ( err, result ) {

            if ( !err ) {

                if( result.length ) {

                    result[0]['abc'].def[0]['new_key']  = 'blah';
                    response['success'] = true;
                    response['result'] = result[0]['abc'].def;
                    response['msg'] = 'data fetch';
                    res.json(response);
                } else {

                    response['success'] = false;
                    response['result'] = '';
                    response['msg'] = 'No record found';
                    res.json(response);
                }
            } else {

                response['success'] = false;
                response['result'] = '';
                response['msg'] = 'Error';
                res.json(response);
            }
        });

我也遇到了同样的问题，我使用这个

解决了这个问题

connection.modal.find( { 'user_id' : user_id }, { 'abc.def' : true}, function ( err, result ) {
 /// ADD THIS LINE /////////
result = JSON.parse(JSON.stringify(result));
 ....
