The barrier parameters of weakly and tightly bound nuclei on different target nuclei are obtained by the São Paulo potential, and the total reaction cross sections are obtained from analyzing the experimental elastic scattering data. In order to explore the breakup effects we systematically analyze the total reaction function F($x$) of weakly and tightly bound projectiles on light, medium-mass, and heavy target nuclei in comparison with the universal function F${}_0$($x$). From this comparison, we conclude that the breakup effect is not important for weakly bound projectiles on the light target nuclei, is suppressed on medium-mass and heavy target nuclei above the Coulomb barrier, and, oppositely, is enhanced for some weakly bound projectiles at energies near and below the Coulomb barrier. More experiments need to be performed for some unstable weakly bound nuclei on medium-mass and heavy target nuclei at low energies especially at sub-barrier energies.
