Content
The measurements of hadronic form factors using the data samples collected with the BESIII detector at BEPCII collider are presented. The cross section of $e^+e^-\to p\bar{p}$ at 12 energies from $2232.4$ to $3671.0$ MeV are measured, the electromagnetic form factor is deduced, and the ratio $|G_{E}/G_{M}|$ is extracted by fitting the polar angle distribution. The cross section of $e^+e^-\to\pi^+\pi^-$ between effective center-of-mass energy $600$ and $900$ MeV is measured by the ISR return method using the data set with the integrated luminosity of $2.93$ fb$^{-1}$ taken at $\psi(3773)$ peak, the pion form factor $|F_\pi|^2$ is extracted. The other preliminary results about the form factors of $e^+e^-\to\Lambda\bar\Lambda$, $\Lambda_c^+\bar\Lambda_c^-$, $K^+K^-$, and the measurement of the resonant parameters of $J/\psi$ will also be mentioned.
