We study its strong decays with the combination of the Bethe-Salpeter method and the $^3P_{_0}$ model. Its electromagnetic (EM) decay is also calculated by the Bethe-Salpeter method within Mandelstam formalism. The strong decay widths are {$\\Gamma[X(3842)\\rightarrow D^{0}\\bar{D}^{0}]=1.28$ MeV}, $\\Gamma[X(3823)\\rightarrow D^{+}D^{-}]=1.08$ MeV, and the ratio ${\\cal B}[X(3842)\\rightarrow D^{+}D^{-}]/{\\cal B}[X(3823)\\rightarrow D^{0}\\bar{D}^{0}]=0.84$.
