How to pass a second parameter to geolocation success function ?

问题

This is what I'd like to do:

navigator.geolocation.getCurrentPosition( wallEventByCat( variable, position ), handle_errors );

in order to have this kind of callback:

function wallEventByCat( position, category )
{
}

Is this doable ? if yes, how ?

Thanks

You should use an anounymous function like:

navigator.geolocation.getCurrentPosition( function(position){
     wallEventByCat( variable, position );
}, handle_errors );
