javascript - 更改输入文本时不会应用过滤器 : ReactJS

Question

我正在尝试实现一个搜索过滤器，用于搜索整个表中的字符。过滤器未正确应用。我正在使用react-table作为数据网格。我在每个输入上触发更改处理程序，然后使用过滤器过滤掉数据。无法实现相同的目标

如果有帮助，我们将不胜感激。

在您的第二种方法中，错误来自handleSetData = data =>{this.setState({data});};您正在根据filterdata更改数据状态，这就是为什么您的数据会消失您需要做的是传递设置数据过滤器状态，如下所示:

handleSetData = data => {this.setState({filteredData: data });};

并且在 ReactTable 你需要像这样渲染FilterData或data:

数据={this.state.filteredData ? this.state.filteredData : 数据}

import React from "react";
import ReactDOM from "react-dom";
import GlobalSearchComponent from "./GlobalSearchComponent";
import ReactTable from "react-table";
import "react-table/react-table.css";
import "./styles.css";

export default class App extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      data: [],
      filteredData: null,
      columns: [],
      searchInput: ""
    };
  }

  componentDidMount() {
    this.getData();
    this.getColumns();
  }

  getColumns = () => {
    let columns = [
      {
        Header: "First Name",
        accessor: "firstName",
        sortable: false,
        show: true,
        displayValue: " First Name"
      },
      {
        Header: "Status",
        accessor: "status",
        sortable: false,
        show: true,
        displayValue: "Status "
      },
      {
        Header: "Visits",
        accessor: "visits",
        sortable: false,
        show: true,
        displayValue: " Visits "
      }
    ];
    this.setState({ columns });
  };

  getData = () => {
    let data = [
      { firstName: "aaaaa", status: "Pending", visits: 155 },
      { firstName: "aabFaa", status: "Pending", visits: 155 },
      { firstName: "adaAAaaa", status: "Approved", visits: 1785 },
      { firstName: "aAaaaa", status: "Approved", visits: 175 },
      { firstName: "adaSaaa", status: "Cancelled", visits: 165 },
      { firstName: "aasaaa", status: "Cancelled", visits: 157 },
      { firstName: "aweaaaaaewea", status: "Approved", visits: 153 },
      { firstName: "adaAAadsdweaa", status: "Approved", visits: 17585 },
      { firstName: "aAaaaa", status: "Approved", visits: 175 },
      { firstName: "adadsdSaaa", status: "Cancelled", visits: 165 },
      { firstName: "dsdcdaaaaa", status: "Cancelled", visits: 157 },
      { firstName: "aaadvsaa", status: "Submitted", visits: 5153 },
      { firstName: "aaaaswea", status: "Pending", visits: 1555 },
      { firstName: "aaaaauwe", status: "Submitted", visits: 155 }
    ];
    this.setState({ data });
  };

  handleSetData = data => {
    this.setState({ filteredData: data });
  };

  render() {
    let { data, columns } = this.state;
    return (
      <div>
        <GlobalSearchComponent
          data={this.state.data}
          handleSetData={this.handleSetData}
        />
        <ReactTable
          data={this.state.filteredData ? this.state.filteredData : data}
          columns={columns}
          defaultPageSize={10}
          className="-striped -highlight"
        />
      </div>
    );
  }
}

const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);
