Publication number: 20240104513Abstract: The embodiments of the present disclosure disclose a schedule sharing method, apparatus, and device, the schedule sharing method includes: determining a schedule to be shared after detecting a trigger operation of a first user; and sending the schedule to be shared to a target object based on a share operation triggered the first user. The target object is a page or webpage accessed by a user having an access authority. When a second user views the schedule information of the schedule to be shared through the target object, the authority information of the second user with respect to the schedule to be shared is obtained, so that an operation control matching authority information of the second user is displayed on the page corresponding to the schedule to be shared, thereby allowing the second user to interact with the schedule to be shared through the operation control.Type: ApplicationFiled: December 6, 2023Publication date: March 28, 2024Inventors: Zhaoyi LIU, Danyang ZHANG, Changyu GUO, Xingrun CHEN, Gang HU, Zhong Huang, Haohui QU, Xianjun LV
