已选数据

说明

  • 本插件需要使用uni-popup、uni-transition用于已选择数据弹框,因此需要有这些依赖,请自行导入
  • 本插件基于【虚拟列表】高性能渲染海量数据,加入动态高度、缓冲区
  • 本人只在微信小程序端和H5 使用Chrome浏览器测试和微信开发者工具

安装方式

本组件符合easycom规范,HBuilderX 3.1.0起,只需将本组件导入项目,在页面template中即可直接使用,无需在页面中import和注册`components

基本用法

<hyq-tree :label="props.label" :children="props.children" :key-code="props.keyCode" :has-path="props.hasPath"
        :nodes="props.nodes" :multiple="props.multiple" :checkStrictly="props.checkStrictly" :tree-node="treeNode"
        :feed-back-list="feedBackList" is-check show-search @handleConfirm="handleConfirm"
        @confirmSearch="confirmSearch"></hyq-tree>

<script setup lang="ts">
    import {
        ref
    } from 'vue'
    import {
        treeNode
    } from './data.js'
    const aprop = {
        label: 'name',
        children: 'children',
        keyCode: 'id',
        multiple: true,
        hasPath: false
    }
    const bprop = {
        label: 'name',
        children: 'children',
        keyCode: 'id',
        multiple: true,
        checkStrictly: true,
        hasPath: false
    }
    const cprop = { //单选模式(任意一项)

传入的数据结构说明-treeNode

[
    {
        id: 664214366998,
        name: "校长443",
        children: [{
            id: 885655454545454545678,
            name: "小陆"
        }]
    },
]

选中返回的结果feedBackList:返回一个二维数组

[
    {
        id: xxx,
        name: "xxx",
        path:[],//该值的路径
    },
]

功能说明

1、树形结构展示

2、包含搜索框、面包屑导航

3、单选模式(只选user)、单选模式(选择任意一项)、多选模式(关联下级)、多选模式(选择任意一项)

4、只需传checkList字段就可以回显默认选中

5、已选数据可以进行移除

属性

属性名 类型 默认值 说明
isCheck Boolean false 是否选中
showSearch Boolean false 是否开启搜索
keyCode String id 数据唯一标识(id列的属性名)
label String name 指定选项标签为选项对象的某个属性值
children String children 指定选项的子选项为选项对象的某个属性值
treeNode Array [] trees 传入的树形结构,每个对象必须包含唯一的id值
multiple Boolean false 是否开启多选模式
nodes Boolean false 是否开启单选模式的只选择子项,true :只选子项、false:任意一项
hasPath Boolean false 是否开启选中的数据包含路径
checkStrictly Boolean false 多选模式下是否要关联下级
feedBackList Array [] 选中的列表

事件

事件名 说明 返回值
@handleConfirm 点击完成按钮时触发事件 参数(选中的项值)
@confirmSearch 搜索完成后触发事件 参数(搜索结果的项值)
