Google Maps V3: How to disable "street view"?

The answer is actually in the 2nd paragraph you linked to, but your code should look something like this:

 var mapOptions = {
      center: mapCenter,
      zoom: 10,
      streetViewControl: false,
      mapTypeId: google.maps.MapTypeId.ROADMAP
   };

I'd like to add to the chosen answer and say that if you want to remove the zoom controls (plus-minus buttons) too, then change

  streetViewControl: false,

with

   disableDefaultUI: true,

It was more useful for a mobile touchscreen, since you can zoom in with two fingers.
