如何排除句子中的某些單詞。 正則表達式？

Question

我有一系列句子，例如：

 let arr = [
      "I like an apples",
      "I worked yesterday all day",
      "Anna went on holiday to Madrit",
      "They went to the party to LA"
       ]

我真的想排除一個句子，它有一個 LA 詞。 我不確定使用正則表達式是否可以。 我試過使用：

\b([a-z0-9])\b(!CLT)

讓所有句子都不是洛杉磯，但它不起作用。 知道這是解決這個問題的最佳解決方案嗎？

Answer 1

您可以簡單地使用filter()和includes()

 let arr = [ "I like an apples", "I worked yesterday all day", "Anna went on holiday to Madrit", "They went to the party to LA" ] const res = arr.filter(x => !x.includes('LA')); console.log(res)

如果你只想檢查單詞，那么你可以split(' ')然后filter()

 let arr = [ "I like an apples", "I worked yesterday all day", "Anna went on holiday to Madrit", "They went to the party to LA", "LAST Four words" ] const res = arr.filter(x => !x.split(' ').includes('LA')); console.log(res)

Answer 2

我想你想要這樣的東西-

 let arr = [ "I like an apples", "I worked yesterday all day", "Anna went on holiday to Madrit", "They went to the party to LA", "Hello world LA Demo" ]; let modifiedArr = arr.filter(v => { let regex = /\\bLA\\b/i; if (!regex.test(v)) { return true; } return false; }); console.log(modifiedArr);
