I made my project using Vuejs
and used Swiper
to slide the menu related to the page sections
tag.
I want the Swiper
slider to automatically change when the user scrolls on my page.
I tried the following code:
Swipe code
<swiper :slidesPerView="2.3" :spaceBetween="30" :centeredSlides="true" @swiper="onSwiper"> <swiper-slide v-for="(item,index) in categoriesList" :key="index"> <CategoryItem :title="item.title" :icon="item.icon"/> </swiper-slide> </swiper>
Category Item Example:
categoriesList: [ { foodsCount: 2, title: 'Pizza', icon: 'pizza.svg', tag: 'abcd-efgh-ijkl-mno1', }, ];
part
<section :id="'category-' + item.tag" v-for="(item,index) in categoriesList" :key="index"> <div class="text-center q-mb-md"> <b class="section-title">{{ item.title }}</b> </div> <food-item class="q-mb-md" v-for="i in item.foodsCount" :key="i"/> </section>
Hook created (check scrolling code)
created() { window.onscroll = () => { let current = ""; let prevIndex = this.currentIndex; let sections = document.querySelectorAll('section') sections.forEach((section) => { const sectionTop = section.offsetTop; if (pageYOffset >= sectionTop) { current = section.getAttribute("id"); this.currentIndex = this.categoriesList.findIndex(item => item.tag === current.replace('category-', '')) } }); if (this.currentIndex !== prevIndex) { let i = 0 document.querySelectorAll('.swiper-slide').forEach(item => { if (this.currentIndex === i) { item.classList = 'swiper-slide swiper-slide-active' } else if (this.currentIndex === (i - 1)) { item.classList = 'swiper-slide swiper-slide-next' } else if (this.currentIndex === (i + 1)) { item.classList = 'swiper-slide swiper-slide-previous' } else { item.classList = 'swiper-slide'; } i++; }) } };
Note: I cannot use the SlideTo
function because it breaks the dynamics when scrolling.
I think, it has something to do with transform
style swiper-wrapper
div but I can't handle it.
<div class="swiper-wrapper" style="transition-duration: 0ms; transform: translate3d(*, *, *);">
Is there any solution?
That’s what I do, no problem.
