要实现多个card组件之间的拖动和数据交换效果,可以使用Vue3的Composition API和element-plus提供的draggable指令。以下是一个简单的实现过程:
1. 安装element-plus和vuedraggable插件
```
npm install element-plus vuedraggable --save
```
2. 在main.js中导入element-plus和vuedraggable
```javascript
import { createApp } from 'vue'
import App from './App.vue'
import ElementPlus from 'element-plus'
import 'element-plus/lib/theme-chalk/index.css'
import draggable from 'vuedraggable'
const app = createApp(App)
app.use(ElementPlus)
app.component('draggable', draggable)
app.mount('#app')
```
3. 在组件中使用draggable指令实现拖动效果
```html
<template>
<div>
<draggable v-model="cards" :options="{animation: 200}">
<div v-for="(card, index) in cards" :key="card.id">
<el-card class="card">
<div>{{ card.content }}</div>
</el-card>
</div>
</draggable>
</div>
</template>
<script>
import { reactive } from 'vue'
export default {
setup() {
const cards = reactive([
{ id: 1, content: 'Card 1' },
{ id: 2, content: 'Card 2' },
{ id: 3, content: 'Card 3' },
{ id: 4, content: 'Card 4' }
])
return {
cards
}
}
}
</script>
<style>
.card {
margin-bottom: 10px;
}
</style>
```
4. 在draggable指令上添加事件监听,实现数据交换效果
```html
<template>
<div>
<draggable v-model="cards" :options="{animation: 200}" @end="onDragEnd">
<div v-for="(card, index) in cards" :key="card.id">
<el-card class="card">
<div>{{ card.content }}</div>
</el-card>
</div>
</draggable>
</div>
</template>
<script>
import { reactive } from 'vue'
export default {
setup() {
const cards = reactive([
{ id: 1, content: 'Card 1' },
{ id: 2, content: 'Card 2' },
{ id: 3, content: 'Card 3' },
{ id: 4, content: 'Card 4' }
])
const onDragEnd = ({ newIndex, oldIndex }) => {
const movedCard = cards.splice(oldIndex, 1)[0]
cards.splice(newIndex, 0, movedCard)
}
return {
cards,
onDragEnd
}
}
}
</script>
<style>
.card {
margin-bottom: 10px;
}
</style>
```
在onDragEnd函数中,首先通过splice方法将移动的卡片从原位置删除,再通过splice方法将卡片插入到新位置,从而实现数据交换效果。
以上就是在vue3,element-plus开发环境下实现多个card组件之间拖动,并达到数据交换效果的方法。
