Question

I am an array in following format. I am reading following data from a file data.json like this

$.getJSON('data/data.json', function (ids) {
            for (var i = 0; i < ids.length; i++) {
                var id = ids[i];
                teams = id;
                $('<li>' + id + '</li>').appendTo(span);

            }
        });

here is data

[
"109 200",
"109 201",
"102 202",
"103 202"
]

So what I want is to copy this array to another lets say c but in following form

[
"109",
"109",
"102",
"103",
"200",
"201",
"202",
"202"
]

How can I do this using javascript or jquery?

Iterate over the result set, split each element by whitespace, and add the resulting two numbers to two different arrays, each representing one halve, and finally, concatenate the left part with the right part:

var left = [], 
    right = [];
for (var i = 0; i < ids.length; i++) {
  var pair = ids[i].split(" ");
  left.push(pair[0]);
  right.push(pair[1]);
}
var result = left.concat(right);
