Question

我将react-table用于数据网格。我正在尝试实现一个搜索过滤器，该过滤器可搜索整个表中的数据并使用过滤器方法进行过滤。我为搜索维护了一个单独的组件，并在搜索组件中设置了表的数据。从搜索过滤器中删除字符时，过滤将中断。我在这里做错什么了吗？

SearchComponent

import React from "react";
import { Input } from "semantic-ui-react";

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

  handleChange = event => {
    this.setState({ searchInput: event.target.value }, () =>
      this.globalSearch()
    );
  };

  globalSearch = () => {
    let { searchInput } = this.state;
    let filteredData = this.props.data.filter(value => {
      return (
        value.firstName.toLowerCase().includes(searchInput.toLowerCase()) ||
        value.status.toLowerCase().includes(searchInput.toLowerCase()) ||
        value.visits
          .toString()
          .toLowerCase()
          .includes(searchInput.toLowerCase())
      );
    });
    this.props.handleSetData(
      (filteredData.length > 0 && filteredData) || searchInput
        ? filteredData
        : this.props.data
    );
  };

  render() {
    return (
      <>
        <br />
        <Input
          size="large"
          name="searchInput"
          value={this.state.searchInput || ""}
          onChange={this.handleChange}
          label="Search"
        />
        <br />
        <br />
      </>
    );
  }
}

import React from "react";

不更新原始数据，而是在主应用程序中更新过滤的数据。

SearchComponent

从状态中删除filteredData[]，并将全局搜索更改为

globalSearch = () => {
  let { searchInput } = this.state;
  let filteredData = this.props.data.filter(value => {
    return (
      value.firstName.toLowerCase().includes(searchInput.toLowerCase()) ||
      value.status.toLowerCase().includes(searchInput.toLowerCase()) ||
      value.visits
        .toString()
        .toLowerCase()
        .includes(searchInput.toLowerCase())
    );
  });

  this.props.handleSetData(filteredData);

};

应用组件

更改handleSetData以更新filteredData而不是数据。

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

getData = () => {

  let data = [...]

  this.setState({ data, filteredData: data });
};

// change your render to 

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