I want to combine Geolocation and Mouse Position Display (lng/lat; outside of map)from the Openlayer and geocodezip site.I tried various combinations of codes But only the Mouse Position Display (lng/lat; outside of map) is correct.Geolocation does not work.In fact, both of them do not work together. This is the code I've tested the last time. please guide me.Thanks.

</html>There's an error in your code "Uncaught ReferenceError: view is not defined". In line projection: view.getProjection() the variable view is not defined.
Not sure if view needs to be a global variable but if you define it outside the function then the location API is consumed. Jsfiddle here
