表单级别绑定

SpreadJS 支持绑定数据源到表单(绑定类型有表单级别绑定和单元格级别绑定。)

你可以使用 setDataSource 和 getDataSource 方法来设置获取数据源。 在设置数据源之前, 你可以使用 autoGenerateColumns 方法来控制是否自动生成绑定列。 例如: 你也可以使用 getDataItem 方法来获取指定行的数据信息。 你可以像这个例子版将数据字段绑定到指定的列:
import * as React from 'react'; import * as ReactDOM from 'react-dom'; import './styles.css'; import { AppFunc } from './app-func'; import { App } from './app-class'; // 1. Functional Component sample ReactDOM.render(<AppFunc />, document.getElementById('app')); // 2. Class Component sample // ReactDOM.render(<App />, document.getElementById('app'));
