sortablejs 拖拽排序部分情况动态禁用拖拽

创建 sortablejs 拖拽 排序

&lt;template&gt;
  &lt;div ref="sortablejsRefs" class="sortablejs-list"&gt;
    &lt;span v-for="(item, index) in dataList" :key="item.id"&gt;
      {{ item.title }}
    &lt;/span>
  </div>
</template>

<script>
import Sortable from "sortablejs";
export default {
  name: "sortablejs",
  data() {
    return {
      dataList: [
        {
          id: 0,
          title: "11111111111111111111111111111",
        },
        {
          id: 1,
          title: "22222222222222222222222222222",
        },
        {
          id: 2,
          title: "33333333333333333333333333333",
        },
      ],
      panelEl: null,
    };
  },
  mounted() {
    const panelEl = this.$refs.sortablejsRefs;
    this.panelEl = panelEl;
    Sortable.create(panelEl, {
      animation: 100,
      sort: true,
      onEnd: (evt) => {
        const { oldIndex, newIndex } = evt;
        const oldList = this.dataList;
        oldList.splice(newIndex, 0, oldList.splice(oldIndex, 1)[0]);
        this.dataList = oldList;
        console.log(this.dataList, "dataList");
      },
    });
  },
};
</script>

<style lang="scss" scoped>
.sortablejs-list {
  width: 300px;
}
span {
  display: block;
  line-height: 20px;
  background-color: aqua;
  margin-top: 10px;
}
</style>

引入 sortablejs，使用 c reate创建拖拽，很简单，如果只是子组件加载时需要判断是否禁用，只需使用sort来设置是否禁用拖拽，那如何在初始化之后进行动态禁用拖拽？

动态禁用拖拽

<template>
  <div>
    <el-input v-model="inputs" placeholder="搜索"></el-input>
    <div ref="sortablejsRefs" class="sortablejs-list">
      <span
        :class="{ 'not-sort': inputs }"   // 控制类名
        v-for="(item, index) in dataList"
        :key="item.id"
      >
        {{ item.title }}
      </span>
    </div>
  </div>
</template>

<script>
import Sortable from "sortablejs";
export default {
  name: "sortablejs",
  data() {
    return {
      inputs: null,
      dataList: [
        {
          id: 0,
          title: "11111111111111111111111111111",
        },
        {
          id: 1,
          title: "22222222222222222222222222222",
        },
        {

    };
  },
  mounted() {
    const panelEl = this.$refs.sortablejsRefs;
    this.panelEl = panelEl;
    Sortable.create(panelEl, {
      animation: 100,
      sort: true,
      filter: ".not-sort",  // 过滤.not-sort的元素
      onEnd: (evt) => {
        const { oldIndex, newIndex } = evt;
        console.log(oldIndex, newIndex);
        const oldList = this.dataList;
        oldList.splice(newIndex, 0, oldList.splice(oldIndex, 1)[0]);
        this.dataList = oldList;
        console.log(this.dataList, "dataList");
      },
    });
