Hi guys after fixing one problem with the project I'm working on I've hit another on, now I know this question as been asked quite a good few times but the solutions I have found don't seem to make a difference.
So I'm basically trying to integrate a get directions kind of function into my app, which I have basically taken from the demos of the API, It works perfectly on its own but when I add it to the code it works very very very intermittently, sometimes its there sometimes its not and sometimes its half there and only shows fully when refreshed .
I have included the main parts of the code below that relate to this section of the project help would be appreciated.
This is a reduced form of the HTML

Below is the javscript
$(document).delegate('#Archmap_page', 'pageinit', function () {
navigator.geolocation.getCurrentPosition(initialize);
});
$(document).on('click', '#submit', function(e) {
e.preventDefault();
calculateRoute();
});
var directionDisplay,
directionsService = new google.maps.DirectionsService(),
map;
function initialize()
{
directionsDisplay = new google.maps.DirectionsRenderer();
var mapCenter = new google.maps.LatLng(53.340617, -6.255244);
var myOptions = {
zoom:30,
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: mapCenter
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
directionsDisplay.setMap(map);
directionsDisplay.setPanel(document.getElementById("directions"));
}
function calculateRoute()
{
var selectedMode = $("#mode").val(),
start = $("#from").val(),
end = $("#to").val();
if(start == '' || end == '')
{
// cannot calculate route
$("#results").hide();
return;
}
else
{
var request = {
origin:start,
destination:end,
travelMode: google.maps.DirectionsTravelMode[selectedMode]
};
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
$("#results").show();
/*
var myRoute = response.routes[0].legs[0];
for (var i = 0; i < myRoute.steps.length; i++) {
alert(myRoute.steps[i].instructions);
}
*/
}
else {
$("#results").hide();
}
});
}
}
</script>
I have seen solutions that advise adding things like rel="external" in the anchor tags linking to a page with a google map. Can anyone shed some light on this I know its been asked before, but I wouldn't describe myself as good as javascript its more just a copy and paste job for me here.
Thanks
