IF it's just the chain is broke replace the chain they are sold separately at any hardware store. IF it's the valve you can replace it as well by shutting off the toilet water valve, next disconnect the hose and go buy a float assembly that is similar. Adjust the new float assembly to be the same length as the old one then install gasket on the float and put in the hole for the float, install second gasket on the float on the outside and then install the nut and install the hose. Before you tighten the nut on the float make sure the float valve lines up with the handle and the float then tighten down hook up new chain and tighten the water hose, tighten the nut on the float and open the water valve. Watch the water level fill up if it looks like it's going to run over you will have to adjust the float so that it does not run into the throat of the toilet.
