The invention provides a form construction method and device and a storage medium, and aims to solve the problem that a user interaction behavior response action in a form item cannot be described. The method comprises the steps of obtaining an event identifier corresponding to a specified event after an event sent by a Vue component is monitored as the specified event after an incoming parameterincluding a path of a Veex module sent by a service layer is received; and according to a preset corresponding relationship between the event identifier and the Veex event, sending the Veex event corresponding to the obtained event identifier to the Veex module corresponding to the path, and after the Veex module executes the service logic, sending the data of the Veex module to the visual component to perform form item reconstruction. Therefore, the event triggered by the object in the form item can be monitored, and the event and the Veex event are correspondingly sent to the Veex module, sothat the Veex module can execute the service logic according to the event triggered by the object, and the response to the operation of the object for the form item is realized.
