技术:
ant design vue1.7.8 的UI框架、
vue2.x版本
场景:需要实现div拖拽的效果
效果图:
第一步:安装vuedraggable插件
//npm方式安装
npm i -S vuedraggable
//或使用yarn安装
yarn add vuedraggable
第二步:在页面引入组件
script代码块里
<script>
//第一步 ***.引入组件
import draggable from 'vuedraggable'
export default {
components: {
draggable, //***.第二步
},
data() {
return {
tagsList: [],
treeClass: '',
classList: [],
checkedCategoryKeys: [],
categoryTree: [],
defaultProps: {
children: 'subGroupList',
title: 'groupName',
key: 'groupCode',
},
eventSelectedNode: null,
isLoading: false,
}
},
created() {
this.load_init()
},
methods: {
//拖拽动作 ***.第三步 拖拽完成事件
onDraggableUpdate(e) {
this.isLoading = true
setTimeout(() => {
this.isLoading = false
//老位置
const oldIndex = e.oldIndex
//新位置
const newIndex = e.newIndex
const newSort = this.tagsList[e.newIndex].sort
this.tagsList[e.newIndex].sort = this.tagsList[e.oldIndex].sort
this.tagsList[e.oldIndex].sort = newSort
console.log(this.tagsList)
this.$message.success('顺序变更成功!')
}, 1000)
},
//初始化
load_init() {
for (let index = 0; index < 98; index++) {
this.classList.push({
value: 'val' + index,
label: '树层级_' + index,
})
this.tagsList.push({
value: 'val' + index,
label: '树层级_' + index,
//是否编辑
isEditName: false,
//排序
sort: index,
//loading
isLoading: false,
})
}
},
},
}
</script>
template代码块
<div class="bodyRight">
<div class="bodyRightTitle">
<div><span>标签池</span></div>
<div><a-button type="primary">导入Excel</a-button></div>
</div>
<div class="bodyRightLabel">
<a-spin :spinning="isLoading">
<!-- ***.下面是第四步 -->
<draggable

</span>
<a-input
v-else

v-model="item.label"
:maxLength="22"
@pressEnter="sumbitLabel(item)"
placeholder="请输入标签名称"
@blur="sumbitLabel(item)"
></a-input>
</a-tag>
</transition-group>
</draggable>
</a-spin>
</div>
</div>
