swiper属性/组件查询

vue中使用swiper

步骤：

① npm install swiper 安装

② 基础模板：

<div><swiper class="swiper-box" :direction="'vertical'":grabCursor="true" :mousewheel="true" :mousewheelControl="true" :resistanceRatio = "0":observeParents = "true":options="swiperOption"><!-- 幻灯片内容 --><swiper-slide class="slide-box" v-for="(item, index) in dataList" :key="index"><div><video class="video-box" ref="videos" controls autoplay :videoList="item" :src="item.url" :index="index" ></video></div><div class="info-bar-" >...</div><div class="video-box-right">...</div></swiper-slide></swiper>
</div>

<script>
import { Swiper, SwiperSlide } from 'swiper/vue';
import "swiper/swiper-bundle.css";
export default {name: 'VideoList',components: {Swiper,SwiperSlide,},data() {return {...}}
}
</script>

如图：

属性：

direction = " 'vertical' " ，滑动方向，vertical 垂直方向。（注：一定要两对引号包裹着，否则不生效，还要给swiper设置实高）

modules = "modules"

grabCursor="true"，鼠标手掌形状，拖动时变抓手形状

slidesPerView = "1"，slider容器能够同时显示的slides数量(carousel模式)

mousewheel = "true"，鼠标滚轮控制Swiper切换

setWrapperSize="true"，swiper使用flexbox布局，这个会在wrapper上添加等于slides相加的宽和高

observeParents = "true"，当Swiper 的祖先元素发生变化时，例如show/hide、第一级子元素增加/删除等，则更新Swiper 并触发 observerUpdate 事件

resistanceRatio: 0，抵抗率。边缘抵抗力的大小比例。值越小抵抗越大越难将slide拖离边缘，0时完全无法拖离。

navigation="true"，导航栏

autoplay = "true"，自动播放

loop = "true"，无限循环播放

space-between，每张轮播图之间的距离，该属性不可以和margin属性同时使用。

pagination = "{ clickable: true }"，分页器（是否点击圆点切换轮播）

注：在标签上格式为 :属性=”值“，如 :direction="vertical"

在 js 中格式为属性:值，如 direction:verical

完整代码：

<script>
import { Swiper, SwiperSlide } from 'swiper/vue';
import "swiper/swiper-bundle.css";
export default {name: 'VideoList',components: {Swiper,SwiperSlide,},data() {return {page: 1,swiperOption: {on: {// tap方法 是swiper组件提供的点击方法tap: () => {this.playAction(this.page - 1)},// 上滑（屏幕向上滑时，跳到下一个视频）slideNextTransitionStart: () => {this.page += 1;this.nextVideo(this.page - 1)console.log(this.page);},// 下滑（屏幕向下滑时）slidePrevTransitionEnd: ()=> {if(this.page > 1){this.page -= 1;this.prevVideo(this.page - 1)console.log(this.page);}},}}}},methods: {playAction(index) {     // 入参 是 当前屏幕显示的是第几个视频this.$refs.videos[index].playOrStop();},// 向下nextVideo(index){this.$refs.videos[index-1].stop()this.$refs.videos[index].play()},// 向上prevVideo(index){this.$refs.videos[index+1].stop()this.$refs.videos[index].play()},},setup(){}
