navigator.geolocation.getCurrentPosition Behavior Inconsistency
In your script, the navigator.geolocation.getCurrentPosition function behaves intermittently, working in some cases but not in others. This issue can arise due to various factors:
Infinite Default Timeout:
By default, getCurrentPosition has an infinite timeout, meaning it will never trigger the error callback if it encounters a hang in the back end. To ensure a timeout, specify an optional third parameter:
navigator.geolocation.getCurrentPosition(successCallback, errorCallback, {timeout: 10000});
This parameter sets a maximum wait time of 10 seconds.
Uneven Backend Infrastructure:
Despite claims of reliable geolocation services, some users experience inconsistent behavior across different computers and browsers. This suggests that the back end infrastructure may be less stable than advertised.
Error Handler Reliability:
The proper functioning of the error handler depends on the timeout setting being in place. Without a timeout, the error callback will not be invoked even when geolocation fails.
