In Flexible Classroom, the teacher clicks **Leave Classroom** to leave temporarily, which will not change the classroomroom state. To end the class, refer to the following steps:

1. The teacher calls `leaveClassroom`. The sample code is as follows:

   ```javascript
   this.classroomStore.connectionStore.leaveClassroom(LeaveReason.leave)
   ```

   At this point, the classroom state includes the following:

   ```javascript
   ClassState {
       beforeClass = 0,  // The class has not started
       ongoing = 1,      // The class is running
       afterClass = 2,   // The class has ended, but the classroom still exists
       close = 3         // The classroom is closed
   }
   ```

2. If you want to actively close the classroom, call `RoomStore:updateClassState` to update the room state. The sample code is as follows:

   ```javascript
   // Close the classroom
   this.classroomStore.roomStore.updateClassState(ClassState.close);
   ```

3. To end the class in the background, call [RESTful API](/en/api-reference/api-ref/flexible-classroom/classroom-rest-api#set-the-classroom-state) to set the classroom state to one of the following:

   * `0`: Not started.
   * `1`: Started.
   * `2`: Ended. The class is over, but users can still join and stay during the extended time.
   * `3`: Closed. The classroom is closed after the extended class time. All users are forced out and cannot join again.
