Here is live example: http://travel.demas.me Why can't I see 开发者_JAVA技巧the marker?

I'm seeing this error through Chrome's Developer Tools:

travel.demas.me:14 Uncaught TypeError: Cannot set property 'innerHTML' of null

On this line:

document.getElementById('message').innerHTML = center.toString();

Try removing this for debugging purposes.
