Question

我有一个问题：我有一个自定义的onClick和onChange函数，希望将它们包含在选择复选框中

我该如何实现？这样，当有人选择从MT生成的复选框时，他们会运行自定义的onClick和onChange吗？

还想知道是否可以为搜索栏添加自动填充功能吗？

即，您开始输入文字，它会为您提供与数据中的内容相匹配的值或前5个值或数据中的某些内容，并允许用户通过单击下拉选项来填写自动填充。


  state = {
    items: [],
    chosen: [],
    selected: []
  }

  toggle = (id) => {

    const selected = this.state.selected;

    if (selected.includes(id)) selected.splice(selected.indexOf(id), 1); else selected.push(id);

    this.setState({ selected });
    localStorage.setItem('chosen', JSON.stringify(selected));

    console.log(this.state)

  }

  async componentDidMount() {

    this.setState({
      items: await (await fetch(`${process.env['REACT_APP_API']}/items`)).json(),
      selected: JSON.parse(localStorage.getItem('chosen')) || []
    }); 

  }

render() {
return (

    selection: true,
    pageSize: 10,
    doubleHorizontalScroll: true,

  }}

{/* I CANT GET THIS TO WORK =/ */}
  onRowClick={(event, rowData) => { this.state.selected.includes(rowData.id); }}
  onSelectionChange={data => {this.toggle.bind(this, data.id)}}
 />
</Fragment>

);
}
});

Answer 1

onSelectionChange传递选定行的数组。因此data参数没有id。

要自动完成搜索字段，您可以在github上打开功能请求问题。

Answer 2

您不应直接更改状态，而应使用setState。

import React, { Fragment, Component } from "react";
import MaterialTable from "material-table";
import ReactDOM from "react-dom";

import "./styles.css";

class App extends Component {
  state = {
    items: [],
    chosen: [],
    selected: []
  };

  toggle = id => {
    const selected = this.state.selected;

    if (selected.includes(id)) selected.splice(selected.indexOf(id), 1);
    else selected.push(id);

    this.setState({ selected });
    localStorage.setItem("chosen", JSON.stringify(selected));

    console.log(this.state);
  };

  async componentDidMount() {
    this.setState({
      items: await (await fetch(
        `${process.env["REACT_APP_API"]}/items`
      )).json(),
      selected: JSON.parse(localStorage.getItem("chosen")) || []
    });
  }

  render() {
    return (
      <Fragment>
        <MaterialTable
          columns={[
            {
              title: "myChecbox",
              render: rowData => {
                return (
                  <input
                    className="toggle_checkbox toggle"
                    type="checkbox"
                    checked={this.state.selected.includes(rowData.id)}
                    onChange={this.toggle.bind(this, rowData.id)}
                  />
                );
              },
              cellStyle: {
                width: 20,
                maxWidth: 20,

                return (

您打错了，在“选项”中激活选择时，必须像数组一样使用dataRow。所以这是一个如何使用它的例子 https://codesandbox.io/s/7zz0v3m91x

关于自动填充，此表现在还不可用，但是如果您像在远程模式下那样使用该表，则几乎可以达到相同的效果，因为它将在表中显示要完成的元素
