How to use Swiper slideTo() in Vue3.0?

Question

Vue version:3.0.2

Swiper version:6.3.5

I'd like to use Swiper's slideTo method in Vue3.0, but it doesn't seem to work.

Can you tell me how to use it? https://codesandbox.io/s/interesting-hooks-1jblc?file=/src/App.vue

You seem to be using one library but referring to the other for documentations.

• https://github.com/nolimits4web/swiper (official)
• https://github.com/surmon-china/vue-awesome-swiper

You are importing the library from swiper/vue, so it has to be the official one; in which case, there is a slight difference in accessing the Swiper instance: You need to store the Swiper instance. (see Controller mode). So in your case:

<template>
  <swiper
    style="border: 1px solid red; width: 400px"
    :slides-per-view="1"
    @swiper="onSwiper"
  >
    <swiper-slide>Slide 1</swiper-slide>
    <swiper-slide>Slide 2</swiper-slide>
    <swiper-slide>Slide 3</swiper-slide>
    <swiper-slide>Slide 4</swiper-slide>
  </swiper>

  <button @click="handleSlideTo">slide to 4</button>
</template>

<script>
import { Swiper, SwiperSlide } from "swiper/vue";
import "swiper/swiper-bundle.css";

export default {
  name: "App",
  
  components: {
    Swiper,
    SwiperSlide,
  },

  data() {
    return {
      swiper: null,
    };
  },

  methods: {
    onSwiper(swiper) {
      this.swiper = swiper;
    },

    handleSlideTo() {
      this.swiper.slideTo(3);
    },
  },
};
</script>

Not to be confused with the use of ref by the other library (vue-awesome-swiper).
