Parsing Json Array Object in specific format in javascript

Question

My JSON is:

var json = '{"name":"GeoFence","coordinate":[[1,2],[3,4],[5,6]]}',
obj = JSON.parse(json);
alert(obj.coordinate);

But i need to set the values of coordinates as follows:

var myTrip=[new google.maps.LatLng(1,2),new google.maps.LatLng(3,4),new google.maps.LatLng(5,6)];

Answer 1

Traverse the coordinates and create a new object for each, and add that to myTrip :

var myTrip = [];

for(var i=0; i < obj.coordinate.length; i++) {
    myTrip.push(new google.maps.LatLng(obj.coordinate[i][0],obj.coordinate[i][1]))
}

Answer 2

How about this:

var json = '{"name":"GeoFence","coordinate":[[1,2],[3,4],[5,6]]}',
var obj = JSON.parse(json);
var myTrip = [];
for (var i = 0; i < obj.coordinate.length; i++) {
    myTrip[i] = new google.maps.LatLng(obj.coordinate[i][0], obj.coordinate[i][1]);
}

Answer 3

You need to iterate over the collection of the coordinates:

var myTrip = getCoordinate ();

var getCoordinate = function(){
        var ret = [];

        for(var i = 0, length = coordinate.length; i < length; i++){
           ret.push(new google.maps.LatLng(coordinate[i][0], coordinate[i][1]))
        }

       return ret;
}
