Vue 在element-plus 中手动切换轮播图

复制官网demo

 <div class="block text-center" m="t-4" >
    <el-carousel trigger="click"  height="150px" :autoplay=false ref="myRef">
    <el-carousel-item v-for="item in 3" :key="item" >
        <h3 class="small justify-center" text="2xl">
            <router-view></router-view>
        </h3>
    </el-carousel-item>
    </el-carousel>
</div>

编写JS逻辑 : 轮播图根据changeIndexTo传入的value决定内容

<script setup>
    import {ref} from "vue"
    const myRef = ref(null)

    const changeIndexTo = (value)=>{
        console.log( myRef.value)
            myRef.value.setActiveItem(value) 
    }
</script>
