在vue中使用swiper实现PC端横向内容左右滑动的效果

官方文档 https://www.swiper.com.cn/

效果图：

1、安装

cnpm install swiper vue-awesome-swiper --save

2、引入

（1）全局在main.js中引入

import VueAwesomeSwiper from 'vue-awesome-swiper'
import 'swiper/css/swiper.css'
Vue.use(VueAwesomeSwiper)

（2）局部引入

import { Swiper, SwiperSlide } from 'vue-awesome-swiper'
import 'swiper/css/swiper.css'

export default {
    components: {
       Swiper,
       SwiperSlide
    }
}

3、使用：

 用到的API：

this.swiper.setTransition(1000);//设定过渡的时间

this.swiper.setTranslate(-1000);//设定位移，可以为正数

获取某个点的宽高、位置：

this.$refs.item.getBoundingClientRect()   

代码：

<template>
    <div class="SegmentCell">
        <a @click="stepActive=item" v-for="item in [6,8,12,20,10]" :key="item" class="m-l-r-20">{{item}}</a>
        <swiper class="swiper-container" ref="mySwiper" :options="swiperOptions">
            <swiper-slide class="swiper-slide" :style="swiperStyle">
                <div class="item t-a-c" v-for="item in stepActive" :ref="'item'+item" @click="setTranslate(item)">{{item}}</div>
            </swiper-slide>
        </swiper>
    </div>
</template>

<script>
    // 引入swiper滑动组件
    import { Swiper, SwiperSlide } from 'vue-awesome-swiper'
    import 'swiper/css/swiper.css'
    export default {
        components: {
            Swiper,
            SwiperSlide
        },
        data() {
            return {
                swiperStyle: {},
                swiperOptions: {
                    slidesPerView: 'auto',
                    freeMode: true,   // 随意拖动位置
                    mousewheel: true
                },
                stepActive: 6
            }
        },
        computed: {
            swiper() {
                return this.$refs.mySwiper.$swiper;
            }
        },
        watch: {
            stepActive: {
                handler(newVal,oldVal) {
                    console.log(this.stepActive);
                    if(this.stepActive) {
                        this.swiperStyle = "width:"+ 500*this.stepActive/16 + "rem";    // 动态设置宽度
                    }
                },
                immediate: false
            }
        },
        mounted() {
            
        },
        destroyed() {
            this.swiper.destroy(false);  
        },
        methods: {
            setTranslate(index) {
                console.log(index,this.swiper.width,this.$refs["item"+index][0].getBoundingClientRect())
                this.swiper.setTransition(1000);// 设定过渡的时间
                this.swiper.setTranslate( 0 - 500*(index-1) + (this.swiper.width/2 - 500/2) );//设定位移，可以为正数
            }
        }
    };
