The invention discloses a needle control method for knitting and eyeleting of a computerized flat knitter. The method comprises the steps that 1, a selection needle, a spring needle and a long needle enter needle walking grooves synchronously; 2, a knitter head swings leftwards and rightwards to enable a crochet hook to be in a knitting state, and a needle selector does not work; 3, the selection needle passes through a first needle push triangle and a second needle push triangle to enter a needle-connection doubling-stitch needle walking groove; 4, the spring needle walking groove changes along with needle-selection needle-connection doubling-stitch needle walking groove; a stepping motor rotates, left and right needle connection pressing pieces slide upwards, a doubling-stitch pressing piece slides downwards, and a spring needle doubling-stitch needle walking groove is formed; the spring needle enters the lower end of a back stitch triangle, passes through the left needle connection pressing piece, doubling-stitch pressing piece and the right needle connection pressing piece and pushes the long needle, so that the long needle enters a w-shaped disc medium-needle groove from the upper end of the return needle triangle, passes through the middle of a stitch setting guide block and slides leftwards and rightwards between a W-shaped protector and the stitch setting guide block; the long needle pushes the crochet hook, so that crochet hook knitting and eyeleting pattern knitting are achieved.
