React使用antd Table生成层级多选组件
一、需求
用户对不同的应用需要有不同的权限,用户一般和角色关联在一起,新建角色的时候会选择该角色对应的应用,然后对应用分配权限。于是写了一种实现的方式。首先应用是一个二级树,一级表示的是应用分组,二级表示的是应用,这是table的最左边的数据。然后是按钮的数据,这里显示在table的头部。
二、效果图如下
三、具体代码

利用antd table实现层级多选组件。
具体思路:
addDataPid(btnGroupColumns, appData) {//生成新的列, 并且为非表头的每一个单元格设置固定 id,(防止表格渲染时 id发生变化) if(!appData) return; for(var i=0; i<appData.length; ++i) { for(var j=0; j<btnGroupColumns.length; ++j) { if(!appData[i][btnGroupColumns[j].colname]) { appData[i][btnGroupColumns[j].colname] = btnGroupColumns[j].id + ‘_‘ + (++this.cid);//为这一行数据添加新的列 //判断应用对应的按钮是否已经选择上, judgeDefaultChecked if(appData[i].select && appData[i].select[btnGroupColumns[j].id]) {//btnGroupColumns[j].id == btnGroupId this.checkboxIdMapState.put(this.cid, true); } else { this.checkboxIdMapState.put(this.cid, false); } } else if(btnGroupColumns[j].colname == ‘name‘){ if(appData[i][btnGroupColumns[j].colname].indexOf(‘_‘) >= 0) continue; appData[i][btnGroupColumns[j].colname] += ‘_‘ + (++this.cid); this.checkboxIdMapState.put(this.cid, false); } } this.addDataPid(btnGroupColumns, appData[i].children); }}addColName(btnGroupColumns, appData){//为每一列添加 映射字段 colname if(btnGroupColumns) { btnGroupColumns.map((elem, index)=> { if(!elem.colname) { elem.colname = elem.id; } elem.cid = ++this.cid; }); } if(appData) { this.addDataPid(btnGroupColumns, appData); /////清空数据 var keySet = this.childrenRow.keySet(); for(var key in keySet){ if(this.childrenRow.get(keySet[key]) && this.childrenRow.get(keySet[key]).length) this.childrenRow.get(keySet[key]).length = 0; } /////总行数 this.rowNum = 0; this.addChildrenRow(appData); ++this.rowNum; /////判断应用对应的checkbox是否选中,列头对应的checkbox是否选中 this.checkGroupAndColumnState(); }}
2.RoleCheckbox.js
import {Checkbox} from ‘antd‘;import React from ‘react‘;class RoleCheckbox extends React.Component{ constructor(props) { super(props); this.onChange = this.onChange.bind(this); } onChange(e){ const cid = this.props.cid; const btnGroupId = this.props.btnGroupId; const appId = this.props.appId; this.props.onChecked(cid, btnGroupId, appId, e.target.checked); } render() { const checked = this.props.checked; const title = this.props.title; const cid = this.props.cid; return( <div> <Checkbox checked={checked} onChange={this.onChange}/>{title} </div> ); }}module.exports = RoleCheckbox;
封装antd 的Checkbox组件
3.Map.js
class Map { constructor(){ this.container = new Object(); } put(key, value){ this.container[key] = value; } get(key){ return this.container[key]; } keySet() { var keyset = new Array(); var count = 0; for (var key in this.container) { // 跳过object的extend函数 if (key == ‘extend‘) { continue; } keyset[count] = key; count++; } return keyset; } size() { var count = 0; for (var key in this.container) { // 跳过object的extend函数 if (key == ‘extend‘){ continue; } count++; } return count; } remove(key) { delete this.container[key]; } toString(){ var str = ""; for (var i = 0, keys = this.keySet(), len = keys.length; i < len; i++) { str = str + keys[i] + "=" + this.container[keys[i]] + ";\n"; } return str; }}module.exports = Map;
js实现的Map工具类。
四、需求变更
功能虽然完成了,但是总是避免不了需求的变更。要求选择左边应用对应的checkbox时,不在操作该应用对应的按钮的checkbox,也就是整个行不是全选了。应用对应的checkbox用来进行删除操作。
1.改变后的Table效果
