Javascript Create Json -


i'm trying create , post json message in following format:

var listobjects = [];  $.each(results, function(index, value){  var item = new object(); item.title = value.title; item.code = value.code;  listobjects.push(item);  });  var jsonresult = json.stringify(listobjects);

basically create json this:

[{"title":"product 1","code":123456789012}, {"title":"product 2","code":123456789012}, {"title":"product 3","code":123456789012}, {"title":"product 4","code":123456789012}, {"title":"product 5","code":123456789012}, {"title":"product 11","code":123456789012}, {"title":"product 12","code":123456789012}, {"title":"product 13","code":123456789012}]

how can if want add metadata json not repeat each item @ top ... this:

category: x type:   y ...    items:          title: .....          code: ......

so category , type define whole items in json not repeated each item ...

how can if want add metadata json not repeat each item @ top

use object wrapper meta data , items array:

var jsonresult = json.stringify({     category: x,     type:     y,     items:    listobjects });

i'm assuming there x , y variables; if they're meant literals, put them in quotes.

side note: in javascript, there's no reason use new object. use {}, same thing. can put property initializers within it, rather assigning properties afterward. here's $.each changes (and indentation):

$.each(results, function(index, value){      var item = {         title: value.title,         code: value.code     };      listobjects.push(item);  });

you can, of course, combine those:

$.each(results, function(index, value){      listobjects.push({         title: value.title,         code: value.code     });  });

last not least: you're doing $.each $.map for:

var listobjects = $.map(results, function(index, value){     return {         title: value.title,         code: value.code     }; });

node.js - How do I prevent MongoDB replica set from querying the primary? -

read-operations-only: is there way have mongodb replica set, make mongodb instance on box connected to, mongodb gets queried? i have 3 ec2 instances behind aws load balancer. on each ec2 instance runs mongodb, part of replica set. i have express endpoints on nodejs , connect replica set follows mongodb.mongoclient.connect('mongodb://1.1.1.1,2.2.2.2,3.3.3.3.', function (err, db) { if (err) { complete('{}'); } else { i distribute load of queries evenly across 3 instances of mongodb replica set instead of default having queries routed ec2 instance primary mongodb defined, because destroys point of load balancer (which balance load of queries across 3 instances evenly). my understanding when connecting mongodb replica set, primary instance selected unless primary instance down, , therefore purpose of every secondary instance serve backup. in example people call hot,cold,cold. because there 2...
