Saving variables outside of navigator.geolocation.getCurrentPosition? (javascript)
I'm trying to play with the scope of js to pull a variable out of navigator.geolocation.getCurrentPosition var lat; function callback (position) { lat = position.coords.latitude; } navigator.geolocation.getCurrentPosition(callback,fail,{timeout:10000}); // after getCurrentPosition succeeds alert(lat); // this alerts null The above code cannot store position.coords.latitude in the lat variable because of the scope. Is there a way to do this? You have to remember the async\ajax nature. this is the execution order of your code: var lat; alert(lat); // this alerts null navigator.geolocation
