Can you explain in a bit more detail what you are trying to do and how it is related to OpenStreetMap?

What sort of platform are you asking about (on the web, on a phone, something else?) and what sort of map (tile-based, vector based, something else again?)

Questions such as "how do I find the user's location from a web page" (which may be part of what you are asking) are general web technology questions - you'll find answers at this help site but much more in-depth answers elsewhere.

now can help me ?

er - not really, since it's unclear what "navigator" is in your code snippet. I can show you an example of web-based geolocation that works, though - see here. That's using leaflet (as you seem to be doing also). Pressing the "centre" button here will invoke it.

can set marker to center location ?

There's a ton of examples at the leaflet site here - including setting markers.
