We consider the photoproduction of $\\jpsi$ in the energy range relevant to HERA. The Weizs\\\"acker-Williams approximation is adopted in the evaluation of the cross sections for $ep$ collisions. We found that this process can give another independent test for the color-octet mechanism, and the different features for the two color-octet processes may provide further informations on the mechanism for inelastic $\\jpsi$ photoproduction.
