Method and device for controlling logic of questionnaires

An embodiment of the invention discloses a method and a device for controlling logic of questionnaires. The method includes acquiring questions in the questionnaires and determining categories of the various questions; displaying questions of first subject categories in the questionnaires and hiding the questions of second question categories; displaying second questions corresponding to first questions specified by selection instructions after the selection instructions for selecting the first questions are received. The categories of the questions in the questionnaires include the first question categories and second question categories. The first questions are questions required to be displayed at present, and the second questions are questions which can be selected according to the first questions. According to the scheme, the method and the device have the advantages that the questions with set logic control are hidden in the questions in the questionnaires, and accordingly the questions can be displayed in incremental modes for users in operation procedures without disappearing; the selection instructions of the users are not adopted in a unidirectional jumping mode, accordingly, the subjects can be hidden without constraints on the quantities of selected subjects, and the questionnaires can be flexibly logically controlled.
