javascript - searchWords.filter不是函数

我正在使用react-highlight-words包来突出显示在文本框中输入的文本

我提到了react-highlight-words文档，因为它们将searchWords作为数组传递。 https://www.npmjs.com/package/react-highlight-words

，但问题是当我将其传递给数组let searchBarText = [];时，我遇到了错误searchWords.filter不是函数。

您能告诉我如何修复它，以便将来我自己修复。

在下面提供我的沙箱和代码段。

https://codesandbox.io/s/00nm6k8orp

class SearchBar extends React.Component {
  constructor() {
    super();
    this.state = {
      // testHighlight: {}
      testHighlight: []
    };
    this.handleChange = this.handleChange.bind(this);
  }

  handleChange(e) {
    console.log(e.target.value); // your search bar text
    let object = document.getElementById("myDiv");
    console.log(object.textContent); // your div text

    // now that you have the two strings you can do your search in your favorite way, for example:
    let searchBarText = [];
    searchBarText = e.target.value;
    console.log("searchBarText --->", searchBarText);

    let divText = object.textContent;
    console.log("divText --->", divText);

    if (divText.includes(searchBarText)) {
      console.log("the div text contains your search text");
    } else {
      console.log("the div text doesn't contain search text");
    }

    // this.setState({ testHighlight: response.data });

    this.setState({ testHighlight: searchBarText });
  }

  render() {
    return (
      <div>
        <input
          type="text"
          className="input"
          onChange={this.handleChange}
          placeholder="Search..."
          // highlightText={this.handleChange}
          testHighlight={this.state.testHighlight}
        />

        <HighlighterImplementation testHighlight={this.state.testHighlight} />
      </div>
    );
  }
}

最佳答案

在SearchBar.js文件中，您正在将testHighlight更新为字符串:

this.setState({ testHighlight: searchBarText });

您不是要这样做:

 this.setState({ testHighlight: [searchBarText] });

或者，如果要将其添加到现有阵列中:

this.setState({ testHighlight: [...this.state.testHighlight, searchBarText] });
