Why Does navigator.geolocation.getCurrentPosition Fail Intermittently?

navigator.geolocation.getCurrentPosition Occasionally Fails

Despite seemingly straightforward code, you have observed inconsistent behavior with navigator.geolocation.getCurrentPosition, experiencing failures after several successful executions.

One potential issue lies in the default infinite timeout for getCurrentPosition. Without setting a timeout, the error handler will never be triggered if the request hangs indefinitely. To avoid this, specify a timeout in the function call:

navigator.geolocation.getCurrentPosition(successCallback,errorCallback,{timeout:10000});

The timeout ensures that you receive a response within a specified timeframe, such as 10 seconds in this example.

However, even with the timeout resolved, you have encountered additional variations in behavior across different devices and browsers. This suggests that the underlying infrastructure for geolocation may not be as reliable as advertised.

Specifically, you have noticed that:

• Different computers within the same network have varying degrees of success with geolocation.
• The same computer can have intermittent failures, working at one time but failing later.

These observations indicate that the back-end infrastructure may be less consistent than expected. It is essential to note that setting the timeout parameter allows the error handler to function correctly when the request times out.

In summary, while setting a timeout can mitigate the issue of an infinite request, the underlying inconsistency of the geolocation infrastructure may still lead to occasional failures.
