Menu
Hi there,
the following codes functions work only in this order: Press the stop button THEN press the start button
for some reason it does not fully work if I press the buttons in this order: start button THEN press the stop button
my question is, is it not working because of the order of the functions. Heres my code:
[CODE]<!DOCTYPE html>
<html>
<body>
<p id=”demo”>Click the button to get your position:</p>
<button onclick=”getLocation()”>Try It</button>
<button onclick=”stopLocation()”>Stop</button>
<button onclick=”additionStats()”>Add</button>
<div id=”mapholder”></div>
<script src=”http://maps.google.com/maps/api/js?sensor=false”></script>
<script>
var x=document.getElementById(“demo”);
function getLocation()
{
if (navigator.geolocation)
{
navigator.geolocation.watchPosition(showPosition,showError);
}
else{x.innerHTML=”Geolocation is not supported by this browser.”;}
}
function showPosition(position)
{
lat=position.coords.latitude;
lon=position.coords.longitude;
latlon=new google.maps.LatLng(lat, lon)
mapholder=document.getElementById(‘mapholder’)
mapholder.style.height=’250px’;
mapholder.style.width=’500px’;
var myOptions={
center:latlon,zoom:14,
mapTypeId:google.maps.MapTypeId.ROADMAP,
mapTypeControl:false,
navigationControlOptions:{style:google.maps.NavigationControlStyle.SMALL}
};
var map=new google.maps.Map(document.getElementById(“mapholder”),myOptions);
var marker=new google.maps.Marker({position:latlon,map:map,title:”You are here!”});
}
function stopLocation(position)
{
if (navigator.geolocation)
{
navigator.geolocation.getCurrentPosition(showStopPosition,showError);
}
else{x.innerHTML=”Geolocation is not supported by this browser.”;}
}
function showStopPosition(position)
{
lat1=position.coords.latitude;
lon1=position.coords.longitude;
x.innerHTML=”Latitude: ” + lat1 +
“<br>Longitude: ” + lon1;
}
function showError(error)
{
switch(error.code)
{
case error.PERMISSION_DENIED:
x.innerHTML=”User denied the request for Geolocation.”
break;
case error.POSITION_UNAVAILABLE:
x.innerHTML=”Location information is unavailable.”
break;
case error.TIMEOUT:
x.innerHTML=”The request to get user location timed out.”
break;
case error.UNKNOWN_ERROR:
x.innerHTML=”An unknown error occurred.”
break;
}
}
</script>
</body>
