聊天消息不会通过过滤器发送

Question

Me and my friend are making a chat room for students at our school to use during free time and stuff. I am trying to add a filter so that it will remain SFW. I am very new to JavaScript so when I added the filter you couldn't send messages in the chat anymore. However when I make the filter script a comment and disable it, the messages send just fine.

Filter Code:

    var array = array.js
message.replace(array, "****");

Messaging Code:

        if (message && connected) {
  $inputMessage.val("");
  addChatMessage({
    username: username,
    message: message
  });

  socket.emit("new message", message);
}}

My friend is responsible for the Messaging code since he is much more experienced at JavaScript, but he is very busy and can't add it right now so I am trying to.

Assuming you have a array to filter which is array you could split your message by white space and then check each word to see if it contains a bad word.

Two methodologies (FYI neither is perfect. both of these solutions have plenty of edge cases/loopholes: I'd recommend a js package that has more thought put into it npm: bad-words , npm: censor-sensor , or npm: swearhar )

Both split the message message.split(' ') and then iterate over each word to see if it needs replacing .map . The first checks to see if the current word is in array and the second sees if array words contain the current word, then if so replace with ****

 const array = ['badword', 'nsfw'] let message = 'my message is full of badwords which may be nsfw' message = message.split(' ').map(word => array.includes(word.toLowerCase())? '*****': word).join(' ') console.log(message) message = 'my message is full of badwords which may be nsfw' message = message.split(' ').map(word => array.some(nsfword=>word.toLowerCase().includes(nsfword))? '*****': word).join(' ') console.log(message)
