With the observations of SDO/AIA 304 {\AA} and NVST H{\alpha} bands, wepresent the formation process of an active-region filament in active regionNOAA 11903 during the period from 02:00 UT to 10:00 UT on November 25, 2013. Aseries of jets occurring in the vicinity of the south-western footpoint of thefilament directly ejected cool and hot plasma to filament height and suppliedmaterial for the filament. Some newly emerging flux is found in the vicinity ofthe filament south-western footpoint during these jets. In this paper, wemainly focus on the material supply of the filament. The plasma mass uploadedby the jets and the mass of the filament are estimated, which manifests thefact that the mass carried by jets can supply sufficient material for theformation of the filament. We found two types of jets. one is H-alpha jet, andthe other is EUV jet. The significant finding is that some cool jets seen inthe H{\alpha} band but not in the SDO/AIA bands also could eject the coolmaterial for the filament. These results suggest that cool plasma in the lowatmosphere can be directly injected into the upper atmosphere and become thefilament material by two types of jets. Moreover, the newly emerging flux withnon-potential field plays an important role in the appearances of the jets andthe magnetic structure of the filament.
