Vue的优点
Vue具体轻量级框架、简单易学、双向数据绑定、组件化、数据和结构的分离、虚拟DOM、运行速度快等优势,Vue中页面使用的是局部刷新,不用每次跳转页面都要请求所有数据和dom,可以大大提升访问速度和用户体验。
因业务需求,需要一个树形表格,并且支持拖拽排序,任意未知插入,github搜了下,真不到合适的,大部分树形表格都没有拖拽功能,所以决定自己实现一个。这里分享一下实现过程,项目源代码请看github,插件已打包封装好,发布到npm上
本博文会分为两部分,第一部分为使用方式,第二部分为实现方式

安装方式
npm i drag-tree-table --save-dev
使用方式
import dragTreeTable from 'drag-tree-table'
模版写法
data参数示例
{
lists: [
{
"id":40,
"parent_id":0,
"order":0,
"name":"动物类",
"open":true,
"lists":[]
},{
"id":5,
"parent_id":0,
"order":1,
"name":"昆虫类",
"open":true,
"lists":[
{
"id":12,
"parent_id":5,
"open":true,
"order":0,
"name":"蚂蚁",
"lists":[]
}
]
},
{
"id":19,
"parent_id":0,
"order":2,
"name":"植物类",
"open":true,
"lists":[]
}
],
columns: [
{
type: 'selection',
title: '名称',
field: 'name',
width: 200,
align: 'center',
formatter: (item) => {
return ''+item.name+''
}
},
{
title: '操作',
type: 'action',
width: 350,
align: 'center',
actions: [
{
text: '查看角色',
onclick: this.onDetail,
formatter: (item) => {
return '查看角色'
}
},
{
text: '编辑',
onclick: this.onEdit,
formatter: (item) => {
return '编辑'
}
}
]
},
]
} onDrag在表格拖拽时触发,返回新的list
onTreeDataChange(lists) {
this.treeData.lists = lists
}到这里组件的使用方式已经介绍完毕
实现
•递归生成树姓结构(非JSX方式实现)
•实现拖拽排序(借助H5的dragable属性)
•单元格内容自定义展示
组件拆分-共分为四个组件
dragTreeTable.vue是入口组件,定义整体结构
row是递归组件(核心组件)
clolmn单元格,内容承载
space控制缩进
看一下dragTreeTable的结构
看起来分原生table很像,dragTreeTable主要定义了tree的框架,并实现拖拽逻辑
filter函数用来匹配当前鼠标悬浮在哪个行内,并分为三部分,上中下,并对当前匹配的行进行高亮
resetTreeData当drop触发时调用,该方法会重新生成一个新的排完序的数据,然后返回父组件
下面是所有实现代码
row组件核心在于递归,并注册拖拽事件,v-html支持传入函数,这样可以实现自定义展示,渲染数据时需要判断是否有子节点,有的画递归调用本身,并传入子节点数据
结构如下
{{model[subItem.field]}}
{{model[subItem.field]}}
