I'm using Jquery getJson() to generate a json to be displayed on the
google maps 3 api.
I would like to display the poly line as per the :
[polyline-simple example](http://code.google.com/apis/maps/
documentation/javascript/examples/polyline-simple.html)
function initialize() {
var myLatLng = new google.maps.LatLng(0, -180);
var myOptions = {
zoom: 3,
center: myLatLng,
mapTypeId: google.maps.MapTypeId.TERRAIN
};
var map = new
google.maps.Map(document.getElementById("map_canvas"),
myOptions);
var flightPlanCoordinates = [
new google.maps.LatLng(37.772323, -122.214897),
new google.maps.LatLng(21.291982, -157.821856),
new google.maps.LatLng(-18.142599, 178.431),
new google.maps.LatLng(-27.46758, 153.027892)
];
var flightPath = new google.maps.Polyline({
path: flightPlanCoordinates,
strokeColor: "#FF0000",
strokeOpacity: 1.0,
strokeWeight: 2
});
flightPath.setMap(map);
}
JQuery:
$.getJSON("routefinder", { "lat1": lat1 , "lng1": lng1 , "lat2":
lat2 , "lng2": lng2 }, function(json) {
var poly = new google.maps.Polyline({
path: json,
strokeColor: "#FF0000",
strokeOpacity: 1.0,
strokeWeight: 2
});
poly.setMap(map);
});
the Jquery $.getJSON returns a string with polyline coordinates in
the [new google.maps.LatLng (lat, lng) ] format: [ new
google.maps.LatLng(53.369567, -6.323699), new
google.maps.LatLng(53.367705, -6.317386),new
google.maps.LatLng(53.337705,-6.917386), new
google.maps.LatLng(53.397705,-6.47386)];
But no line is generated, Can i return a json array containing
google.maps.LatLng objects ? Or what would be the best method to
display a polyline from a json. Or can generate a DirectionsResult
object and return it as a json ?
thanks
Paddy
