一、BUG效果如下点击后报错:
二、复现代码import { EditableProTable } from '@ant-design/pro-table';
import React, { useState } from 'react';
const defaultData: any = new Array(3).fill(1).map((_, index) => {
return {
id: (Date.now() + index).toString(),
title: `活动名称${index}`,
decs: '这个活动真好玩',
state: 'open',
created_at: '2020-05-26T09:42:56Z',
};
});
export default () => {
const [editableKeys, setEditableRowKeys] = useState<React.Key[]>(() =>
defaultData.map((item) => item.id),
);
const [dataSource, setDataSource] = useState<any[]>(() => defaultData);
const columns: any = [

);
};
三、解决方案
自己写一个递归的方法将子行追加到选中行下即可,下面展示的是我项目中的代码,不能复制直接用,但思路是一样的。
首先在actionRender
中自定义“增加子行”的操作按钮,其中addChildToSource
为增加逻辑方法:
actionRender: (row, _, dom) => [
<a
key="addChild"
onClick={() => addChildToSource(row.id, type)}
>
增加子行
</a>
],
addChildToSource代码如下:
//增加子行
const addChildToSource = (rowKey: any, type: string) => {
let childRowKey = Date.now(); //rowkey的id不能重复,不然会回填异常
editableKeys[type].push(childRowKey);
let source = formRef.current.getFieldValue(`${type}_source`); //type_source为表格定义的formItem的name
source = addChildToSourceFunc(source, rowKey, childRowKey, type);
const _dict = {};
_dict[`${type}_source`] = source;
formRef.current.setFieldsValue(_dict);
setEditableKeys({ ...editableKeys });
};
上述方法调用的addChildToSourceFunc代码如下:
//删除参数edit及子级edit
const addChildToSourceFunc = (
source: any,
rowKey: any,
childRowKey: any,
type: string,
childName: any = null,
) => {
for (var i = 0; i < source.length; i++) {
const sourceItem = source[i];
if (sourceItem.id === rowKey) {
if (!sourceItem.children) {
sourceItem.children = [];
}
sourceItem.children.push({ id: childRowKey, required: true, param_type: 'string', name: childName });
break;
} else if (sourceItem.children) {
addChildToSourceFunc(sourceItem.children, rowKey, childRowKey, type, childName,);
}
}
return source;
};
成功解决了该问题,解决后的效果:
