Question

例如。我想检查一下，如果我的字符串消息包含一些来自 MySQL 对象（黑名单）的关键字

var message = "My keyword is blacklist";

MySQL 对象

[
  { keyword: 'blacklist'},
  { keyword: 'some'},
  { keyword: 'other'},
  { keyword: 'words'},
]

Answer 1

最佳解决方案如下

const message = 'My keyword is blacklist';
const blockedWords = [
  { keyword: 'blacklist'},
  { keyword: 'some'},
  { keyword: 'other'},
  { keyword: 'words'},
];
function isBlocked(message, blockedWords){
  for (const {keyword} of blockedWords){
      if (message.includes(keyword)){
         return true;
      }
  }
  return false;
}

const result = isBlocked(message, blockedWords);

console.log(result);

console.log(isBlocked('Love JS', blockedWords));

Answer 2

我将信息“消息字符串是否至少包含一个 MySQL 对象”存储在“包含”布尔值中：

var message = "My keyword is blacklist";

var contains = false;

var mysqlObject = [
  { keyword: "blacklist" },
  { keyword: "some" },
  { keyword: "other" },
  { keyword: "words" },
];

for (var i = 0; i < mysqlObject.length; i++) {
  if (message.includes(mysqlObject[i].keyword)) {
    contains = true;
  }
}

console.log(contains);
