I am trying out geolocation with HTML5. For some reason it works on firefox inconsistently and it does not work on chrome and throws an error called object positionerror.

I am trying out geolocation with HTML5. For some reason it works on firefox inconsistently and it does not work on chrome and throws an error called object positionerror.

2 questions

1.) How do i see the actual error (sorry I am new to javascript) 2.) Why is it working differently on chrome开发者_StackOverflow and firefox?

The script is as below -

<script>

if(!navigator.geolocation) {
    alert ('your browser sux');
} else {
    navigator.geolocation.getCurrentPosition(success, error);
}

function success(position) {
    var lat = position.coords.latitude;
    var lng = position.coords.longitude;

    document.write(lat + ', ' + lng);

} 


function error(error) {
    alert ('damn error' +error);




}


JavaScript doesn't have to be hard to debug. Every reasonably modern browser has a debugger:

  • Safari, Chrome, IE8+ and Firefox 4 have built-in developer tools
  • For Firefox 3 and 4, there's also Firebug

As for the actual issues with using navigator.geolocation, you might be interested in the Dive Into HTML5 Geolocation chapter.


To get to Chrome's Developer Tools, either:

  • Wrench -> Tools -> Developer Tools, or
  • View -> Developer -> Developer Tools

If you want to see the JavaScript code, add breakpoints, step through the code, etc. you'd use the Scripts tab. The other tab I spend most of my time in is the Console.
