vue - - - - - vue3使用draggable拖拽组件

一、组件安装

yarn add vuedraggable@next
// or
npm i -S vuedraggable@next

二、插件使用

<template>
  <draggable
    item-key="id"
    class="list-group"
    v-model="list"
    @end="draggerEnd()"
  >
    <template #item="{ element }">
      <a-tag> {{ element }}</a-tag>
    </template>
  </draggable>
</template>
<script>
import { ref, watch, onMounted, reactive, toRefs } from "vue";
import draggable from "vuedraggable";
export default {
  name: "DrawerRight",
  components: { draggable },
  setup() {
    const list = ref([1, 2, 3, 4]);
    const draggerEnd = (v) => {
      console.log("draggerEnd", v);
    };

    return {
      list,
      draggerEnd,
    };
  },
};
</script> 

三、遇到的问题

1. missing required prop： “itemKey”

解决办法：添加item-key="id"
