Question

我是一个满意的Fullpage.js用户！
我只想添加一个类（.num）来显示当前幻灯片数/幻灯片总数。

我正在使用这个功能正常，问题是它不会在幻灯片更改时更新。

$('.section').each(function(){
    var section = $(this),
    sectionSlides = section.find('.slide'),
    totalItems = sectionSlides.length,
    currentIndex = sectionSlides.filter('.active').index() + 2,
    numContainer = section.find('.num');

numContainer.html(currentIndex + ' / ' + totalItems);
});

三种方式：

使用onSlideLeave等回调。
使用其中一个state classes added by fullPage.js

Answer 2

我相信这段代码可以解决我的问题，我只需要改变那个警告吗？

$('#fullpage').fullpage({
    onSlideLeave: function( anchorLink, index, slideIndex, direction, nextSlideIndex){
        var leavingSlide = $(this);

        //leaving the first slide of the 2nd Section to the right
        if(index == 2 && slideIndex == 0 && direction == 'right'){
            alert("Leaving the fist slide!!");
        }

        //leaving the 3rd slide of the 2nd Section to the left
        if(index == 2 && slideIndex == 2 && direction == 'left'){
            alert("Going to slide 2! ");
        }
    }
});
