We propose a sensitive way to test the anomalous HVV couplings (V=W^\pm, Z^0) of the Higgs boson (H), which can arise from either the dimension-3 effective operator in a nonlinearly realized Higgs sector or the dimension-6 effective operators in a linearly realized Higgs sector, via studying the VV scattering processes at the CERN Large Hadron Collider (LHC). We show that, with an integrated luminosity of 300 fb^{-1} and sufficient kinematical cuts for suppressing the backgrounds, studying the process pp \to W^+ W^+ j j \to \l^+ \nu \l^+ \nu j j can probe the anomalous HWW couplings at a few tens of percent level for the nonlinearly realized Higgs sector, and at the level of 0.01-0.08 TeV^{-1} for the linearly realized effective Lagrangian.
