使用 Lodash 获取字符串数组的部分字符串匹配

Question

我有一个字符串数组，想要使用 Lodash 查找部分字符串匹配。我希望搜索能够找到完整匹配项（例如与

broken

），但也希望找到部分匹配项（例如

virus

是

viruses

的一部分）

const textToSearch = 'The broken ship that caught fire also had viruses onboard';
const arrayOfKeywords = ['virus', 'fire', 'broken'];

到目前为止，我有一个方法可以将 textToSearch 拆分为一个数组，然后使用

_.include()

查找完整匹配项

const tokenize = text =>
    text
      .split(/(\w+)/)
      .map(x =>
        _.includes(arrayOfKeywords, x.toLowerCase())
          ? {content: x, type: 'keyword'}
          : x
      );

const tokens = tokenize(textToSearch);

Answer 1

实现模糊匹配的一种方法是使用

_.some

函数和自定义谓词来检查部分匹配。比如：

const textToSearch = 'The broken ship that caught fire also had viruses onboard';
const arrayOfKeywords = ['virus', 'fire', 'broken'];

const tokenize = text =>
  text
    .split(/(\w+)/)
    .map((x) =>
      _.some(arrayOfKeywords, (keyword) => x.toLowerCase().includes(keyword.toLowerCase()))
        ? { content: x, type: 'keyword' }
        : x
    );

const tokens = tokenize(textToSearch);
console.log(tokens);
