How to switch after the page has been fully displayed by the swiper plug-in?

I now have such a need:
is similar to the frequently seen mobile end swiping up and down to switch to the next page;
because some of the information to be displayed is too long to be displayed on the phone screen, you need to be able to scroll to view more information.
example: for example, I have 6 display pages, in which the contents of the third and fourth screens are too long and need to be scrolled to see all of them. The other screens can be displayed in one screen. The effect I want is to switch between the other screens and the complete content of the 3 and 4 screens. Ask God to give me a solution. It may be that carelessness did not find the ending plan in https://www.swiper.com.cn/api, and look at it for help

personal feeling is this
method one:
when it comes to the third, direction becomes vertical becomes vertical
the fourth and
becomes horizontal becomes horizontal
method 2:
or when the second is about to switch to the third

var i=0 //31
var mySwiper = new Swiper('.swiper-container',{
  on: {
    slideChangeTransitionStart: function(){
         if(this.activeIndex==3 && i==0){
             alert('');
             mySwiper.slideTo(2);
         }
    },
  },
})
