We present a combinatorial method for a calculation of the knot Floer homology of (1, l)-knots, and then demonstrate it for nonalternating (1, 1)-knots with 10 crossings and the pretzel knots of type (-2,m, n). Our calculations determine the unknotting numbers and 4-genera of the pretzel knots of this type.
