<el-carousel trigger="click" height="750px" :interval="5000" arrow="always" >

  <el-carousel-item v-for="item in imgs" :key="item"  >
    <div><img :src="item" width="100%"></div>
  </el-carousel-item>

<div><img :src="img2" ></div>

Answer 1

可以监听el-carousel的change事件，示例如下：

<el-carousel height="320px" @change="onChange">
    ...
</el-carousel>
...
methods: {
    onChange(currentIndex, oldIndex) {
        console.log(`当前索引:${currentIndex},原索引：${oldIndex}`);
    }
}
