can't push to array Objects

Question

I have problem with array Objects. I have variable "setting". If I write:

var settings=[];
var tempSettings=[{
   id:1,
   name:"Test1"
  },
  {
    id:2,
    name:"Test2"
   }
];
settings=tempSettings;
console.log(settings[0]);

All right-all work. settings[0]- no problem;

But if I received data from file and do:

 jQuery.getJSON("myurl", function(data) {
console.log(data);                  
var zones=data.split("~");          
jQuery.each(zones, function(key, value) {
          var set = value.split(",");
          var tset={
                  id:set[0],
                  name:set[1]
               };

          settings.push(tset);         
    }); 
});
console.log(settings[0]);

This not work settings[0] - undefined. What my mistake?

Data I received and console.log(data); get me string data.

Added:

console.log(tempSettings) in variant hardcodded does:

[Object { Id=1, name="Test1"},Object { Id=2, name="Test2"} ]

and console.log(settings) in received variables does: [].

but in after click in console I see:

[0] Object { id="3", name="Test3"}, [1] Object { id="4", name="Test4"}.

It's likely that whatever data you're splitting on ~ does not have anything to iterate over. I would inspect what's in data to make sure it has something you expect. — Kyle Falconer

Do you have a sample of data that you receive from the server? — fajarkoe

I can only presume that what you're returning from your server is not valid JSON. The data passed to the callback of .getJSON should be an object, not a string. — scarlz

You're missing the closing }); from your getJSON in that code btw. — Andy

what does console.log(set[0]); and console.log(set[1]); output? also, jQuery.getJSON is not closed properly — briosheje

getJSON is asynchronous. You need to include the console.log within the callback function:

jQuery.getJSON("myurl", function(data) {
  console.log(data);
  var zones=data.split("~");
  jQuery.each(zones, function(key, value) {
    var set = value.split(",");
    var tset = {
      id:set[0],
      name:set[1]
    };
    settings.push(tset);         
  });
  console.log(settings[0]);
});
