google maps call within a For Loop not returning distance
- by Richard Reddy
Hi,
I am calling google maps within a for loop in my javascript as I have mulitple routes that need to be costed separately based on distances.
Everything works great except that the distance is only returned for one of the routes.
I have a feeling that it is something to do with the way I have the items declared within the ajax call for the maps. Any ideas what could be the issue from the code below?
for (var i = 1; i <= numJourneys; i++) {
var mapContainer = 'directionsMap' + i;
var directionContainer = $('#getDistance' + i);
$.ajax({
async: false,
type: "POST",
url: "Journey/LoadWayPoints",
data: "{'args': '" + i + "'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
if (msg.d != '[]') {
var map = new GMap2(document.getElementById(mapContainer));
var distance = directionContainer;
var wp = new Array();
//routes
var counter = 0;
$.each(content, function () {
wp[counter] = new GLatLng(this['Lat'], this['Long']);
counter = counter + 1;
});
map.clearOverlays();
map.setCenter(wp[0], 14);
// load directions
directions = new GDirections(map);
GEvent.addListener(directions, "load", function () {
alert(directions.getDistance());
//directionContainer.html(directions.getDistance().html);
});
directions.loadFromWaypoints(wp, { getSteps: true });
}
}
});
}
