#### 介绍

封装 vue2/vue3 拖拽排序组件组件

#### 使用

```vue
<template>
  <div class="xxxx">
    <el-row class="xxxx-container">
      <span class="xxxx-text">我的收藏: </span>
      <div class="tag-container">
        <jm-draggable class="my-tag-container" :list="list">
          <div class="my-tag" v-for="item in list" :key="item.module_name">
            <i class="el-icon-rank"></i>
            <span @click="$emit('item-click', item)">
              {{ item.module_name }}
            </span>
          </div>
        </jm-draggable>
      </div>
    </el-row>
  </div>
</template>

<script>
import { localCache } from "@/utils/cache";
export default {
  name: "Jmxxxx",
  props: {
    xxxxList: {
      type: Array,
      default: () => [],
    },
  },
  data() {
    return {
      list: [],
    };
  },
  watch: {
    arrayList: {
      handler() {
        localCache.setCache("cicd_xxxx_list", this.list);
      },
      deep: true,
    },
  },
  computed: {
    arrayList() {
      return this.list.map((item) => item.module_name) || [];
    },
  },
  mounted() {
    // 策略1： 获取缓存里面的数据进行 排序，缺点 换了浏览器的话，缓存不在排序数据丢失
    // 策略2： 前端把处理的排序顺序，一起给到后端，后端在进行 update 下，每次页面刷新都读取后端响应数据
    const cicd_xxxx_list = localCache.getCache("cicd_xxxx_list");
    if (cicd_xxxx_list.length) {
      this.list = cicd_xxxx_list;
    } else {
      this.list = this.xxxxList;
    }
  },
};
