Question

I’m using this https://github.com/remy/html5demos/blob/master/demos/geo.html plug in.

If a user has blocked to share his location or if a user uses this in a un supported browser,
I want to show him a text box.

How can this be done in this code?

if (navigator.geolocation) {
    navigator.geolocation.getCurrentPosition(success, error);
} else {
    window.getElementById('idOfTextInput').value = message
}

There is a if else loop,that will show the error

Answer 1

That’s the error part in this code.

if (navigator.geolocation) {
    navigator.geolocation.getCurrentPosition(success, error);
} else {
    error('not supported');
}

If the Geolocation API is not supported at all (if (!navigator.geolocation)), the error('not supported') is executed. Furthermore the getCurrentPosition method takes two callbacks: success and error. The success callback is called when the location request was successful, the error callback is called when it was not.
