question

Dear Developers,

Can anyone explain to me how do I update the FMC Progress page with the following new code?

import {B787_10_FMC} from './B787_10_FMC';
import * as HDSDK from './../../hdsdk/index';


export class B787_10_FMC_ProgressPage {
   
    static _timer = 0;


    static ShowPage1(fmc: B787_10_FMC) {
   
        fmc.cleanUpPage();
        B787_10_FMC_ProgressPage._timer = 0;
        fmc.pageUpdate = () => {
   
            B787_10_FMC_ProgressPage._timer++;
            if (B787_10_FMC_ProgressPage._timer >= 15) {
   
                B787_10_FMC_ProgressPage.ShowPage1(fmc);
            }
        };
