Transition

我们可以使用 transition 组件来实现过渡动画。

组件使用

[
  {
    "name": "Joao",
    "id": "1"
  },
  {
    "name": "Jean",
    "id": "2"
  },
  {
    "name": "Johanna",
    "id": "3"
  },
  {
    "name": "Juan",
    "id": "4"
  }
]

使用组件包裹过渡超出时可以滚动拖拽

  <button @click="handleAdd">Add</button>

  <div class="flex justify-between">
    <VueDraggable
      v-model="list"

    >
      <TransitionGroup
        type="transition"
        tag="ul"
        name="fade"
        class="sort-target"
      >
        <li
          v-for="(item, index) in list"
          :key="item.id"
          class="h-50px bg-gray-500/5 rounded flex items-center justify-between px-2"
        >
          <IconSort class="handle cursor-move"></IconSort>
          <input type="text" v-model="item.name" />
          <iconClose class="cursor-pointer" @click="remove(index)"></iconClose>
        </li>
      </TransitionGroup>
    </VueDraggable>
    <preview-list :list="list" />
  </div>
</template>

<script setup lang="ts">
import { ref } from 'vue'
import { VueDraggable } from 'vue-draggable-plus'

const list = ref([
  {
    name: 'Joao',
    id: '1'
  },
  {
    name: 'Jean',
    id: '2'

  {

])

function handleAdd() {
  const length = list.value.length + 1
  list.value.push({
    name: `Juan ${length}`,
    id: `${length}`
  })
}

function remove(index: number) {
  list.value.splice(index, 1)
}
</script>

<style>
.fade-move,
.fade-enter-active,
.fade-leave-active {
  transition: all 0.5s cubic-bezier(0.55, 0, 0.1, 1);
}

.fade-enter-from,
.fade-leave-to {
  opacity: 0;
  transform: scaleY(0.01) translate(30px, 0);
}

.fade-leave-active {
  position: absolute;
}
.sort-target {
  padding: 0 1rem;
}
</style>

函数使用

[
  {
    "name": "Joao",
    "id": "1"
  },
  {
    "name": "Jean",
    "id": "2"
  },
  {

    "id": "3"
  },
  {
    "name": "Juan",
    "id": "4"
  }
