Question

我有一个字符串数组，我想用另一个单词数组过滤。目标是删除包含第二个参数的一个单词的整个字符串。

让我们以此为示例：

comments = [ "Very useful tutorial, thank you so much!",
  "React is not a damn framework, it's a LIBRARY"
  "Why you put bloody kitten pictures in a tech tutorial is beyond me!",
  "Which one is better, React or Angular?",
  'There is no "better", it depends on your use case, DAMN YOU'
]

bannedWords = ['bloody', 'damn']

我的代码返回了comments的完整数组，我不明白如何过滤bannedWords数组的所有元素。我可以肯定我在那里缺少基本的东西，但是现在我已经被卡住了一段时间，所以...谢谢！

这是我编写的代码：

  return comments.filter(comment => comment.includes(bannedWords) == false)
};

Answer 1

function filterOffensiveComments(comments, bannedWords) {
  return comments.filter(comment => !bannedWords.some(word => comment.includes(word)));
}

.includes仅接受一个String。使用some而不是every，因为它会提前返回。

Answer 2

检查您要遍历的注释中是否不包含.every个禁止词。确保首先在评论中致电toLowerCase：

const comments = ["Very useful tutorial, thank you so much!", "React is not a damn framework, it's a LIBRARY",
  "Why you put bloody kitten pictures in a tech tutorial is beyond me!", "Which one is better, React or Angular?", 'There is no "better", it depends on your use case, DAMN YOU'];
const bannedWords = ['bloody', 'damn'];

const result = comments.filter(comment => bannedWords.every(word => !comment.toLowerCase().includes(word)))
console.log(result);

或者，如果您想构造一个正则表达式：

const comments = ["Very useful tutorial, thank you so much!", "React is not a damn framework, it's a LIBRARY",
  "Why you put bloody kitten pictures in a tech tutorial is beyond me!", "Which one is better, React or Angular?", 'There is no "better", it depends on your use case, DAMN YOU'];
const bannedWords = ['bloody', 'damn'];
const re = new RegExp(bannedWords.join('|'), 'i');

const result = comments.filter(comment => !re.test(comment));
console.log(result);

Answer 3

function filterOffensiveComments(comments, bannedWords) {
  return comments.filter(item=>{
    let shouldDelete = false;
    bannedWords.forEach(word=>{
        if(item.includes(word)){
            shouldDelete = true;
        }
    })
    if(shouldDelete){
        return null
    }
    return item;
  })
};

试图使用回调实现-

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<fieldset  >
  <legend>want car?</legend> 
  <input id="k" type="radio" name="car9" /> <label for="m">yes </label>  
  <input type="radio" name="car9"  value="No" />No 
  <nav id="n">
    <ul>
     <div class="ok" style="display:none">
      <table>
          <tbody>
              <tr>
                  <th></th>
                  <th>Prod</th>
                  <th>Price $</th>
              </tr>
              <tr>
                  <td><input class="ok" name="car10" type="checkbox" /></td>
                  <td>car</td>
                  <td><input class="form-control input-sm" name="txtCostAmount80" value="380" type="text"            readonly="" /></td>
              </tr>
          </tbody>
      </table>
      </div>
  </ul>
  </nav>   
</fieldset>
