The invention discloses an authorizing method of form field value operating authorization. The method comprises the steps of authorizing the form field value operating authorization and selecting the authorized; authorizing the form field value operating authorization comprises the steps of S1, selecting a form to be authorized, and displaying fields need to be controlled by the operating authorization in the form; S2, authorizing the operating authorization of the field values of all the fields separately; the authorized is one or more characters which are independent individuals rather than groups or classes, one character in the same time section can be only related to a single user. However, one user is related to one or more characters. According to the authorizing method of the form field value operating authorization, separate authorizing of the form field value operating authorization can be achieved, and the precision of system management is improved; multiple authorized characters can be selected at the same time to be authorized in bulk, and thus the authorizing efficiency is increased; besides, the method supports template authorizing, two ways are combined, and thus the authorizing efficiency of the form field value operating authorization is increased.
