I'm using this function with google maps

var currgeocoder;
navigator.geolocation.getCurrentPosition(function (position, html5Error) {
    geo_loc = processGeolocationResult(position);
    currLatLong = geo_loc.split(",");
    initializeCurrent(currLatLong[0], currLatLong[1]);
});

function processGeolocationResult(position) {
    html5Lat = position.coords.latitude; //Get latitude
    html5Lon = position.coords.longitude; //Get longitude
    html5TimeStamp = position.timestamp; //Get timestamp
    html5Accuracy = position.coords.accuracy; //Get accuracy in meters
    return html5Lat + ", " + html5Lon;
}
alert(html5Lat);

As you see I didn't use var to make the variable global, but the alert() doesn't work and if I place the alert() inside the function it works well. So how to make the html5lat and html5lon global to be accessed from another function?

The issue is you're alerting it before `processGeolocationResult` has run - `getCurrentPosition` results in an asychronous call. – James Thorpe Oct 14 '15 at 14:14
The issue has nothing to do with scope, but with timing. – Felix Kling Oct 14 '15 at 14:28
