So I have a json object and I need an array with data from that array, like this:

['city 1','city 2','city ..']

So here is the json output:

{"\u0000*\u0000_data":[{"id":"298506","Country":"br","City":"fazenda marrecas","AccentCity":"Fazenda Marrecas","Region":"06","Population":"0","Latitude":"-3.4","Longitude":"-39.883333"},

Pastebin ex, better indent: http://pastebin.com/kEfBSNX5

Here is my current code:

    $.each(data._data, function(i, obj) {
        locations.push([obj.City, obj.Latitude, obj.Longitude]);
    });

Error:

Uncaught TypeError: Cannot read property 'length' of undefined

//LE

  success: function(data)
  {
     var locations = [];
    $.each(data,function(k,v){
        $.each(v,function(key,value){
            locations.push(value['City']); 
        }); 
    });
        console.log(locations);
        return locations;
  }
});

请看看这个小提琴

您是否试图获取数组中的所有城市值。

var city = [];
$.each(data,function(k,v){
    $.each(v,function(key,value){
        city.push(value['City']); 
    }); 
    alert(city)
});

我在小提琴示例中做到了这一点。让我知道这是否是您的要求。
