Answer 1

I had to adjust Jota.Toledos answer a bit so that it works for me, I had to take out the second and the last property of the extras - object:

   navigateToFoo(){
     this._router.navigate([], {
      queryParams: {
        newOrdNum: '123'
      },
      queryParamsHandling: 'merge',
    });
   }
