Javascript 应该只考虑输出选择的相似性

如何解决Javascript 应该只考虑输出选择的相似性

这是我在这里的第一个问题。我开始学习 Javascript，现在正在修改脚本。（开源） 在输入字段（html）上，我告诉一个问题，用“Enter”将其发送到脚本。在constants.js 我写了所有的问题和答案。 如何更改脚本以便代码仅考虑预先创建的问题中的某些关键字。 还要忽略拼写错误？看起来不容易，但我不会学。我在网上和我所有的书上搜索，在 Javascript 中找不到答案。

非常感谢您的帮助！

const prompts = [
  ["hi"],["wie geht es dir"],["auch gut"],["gut"],["sehr gut"],

Index.js 验证输入并搜索正确答案。

const replies = [
  ["hallo"],["mir geht es gut,und dir"],["das ist schön. was kann ich für dich tun"],["oh,das ist nicht schön. was soll ich tun für dich"],

Index.js：

document.addEventListener("DOMContentLoaded",() => {
  const inputField = document.getElementById("input");
  inputField.addEventListener("keydown",(e) => {
    if (e.code === "Enter") {
      let input = inputField.value;
      inputField.value = "";
      output(input);
    

}
  });
});
function output(input) {
  let product;
let text = input.toLowerCase().replace(/\u00e4/g,"ae").replace(/\u00f6/g,"oe").replace(/\u00fc/g,"ue").replace(/\u00df/g,"ss").trim();
  text = text
    .replace(/ a /g," ")   // 'tell me a story' -> 'tell me story'
    .replace(/i feel /g,"")
    .replace(/whats/g,"what is")
    .replace(/please /g,"")
    .replace(/ please/g,"")
    .replace(/r u/g,"are you");
    

    

  if (compare(prompts,replies,text)) { 
    // Search for exact match in `prompts`
    product = compare(prompts,text);
  } else if (text.match(/danke/gi)) {
    product = "Gerne geschehen!"
  } else if (text.match(/(corona|covid|virus)/gi)) {
    // If no match,check if message contains `coronavirus`
    product = coronavirus[Math.floor(Math.random() * coronavirus.length)];
  } else {
    // If all else fails: random alternative
    product = alternative[Math.floor(Math.random() * alternative.length)];
  }

  // Update DOM
  addChat(input,product);
}

function compare(promptsArray,repliesArray,string) {
  let reply;
  let replyFound = false;
  for (let x = 0; x < promptsArray.length; x++) {
    for (let y = 0; y < promptsArray[x].length; y++) {
      if (promptsArray[x][y] === string) {
        let replies = repliesArray[x];
        reply = replies[Math.floor(Math.random() * replies.length)];
        replyFound = true;
        // Stop inner loop when input value matches prompts
        break;
      }
    }
    if (replyFound) {
      // Stop outer loop when reply is found instead of interating through the entire array
      break;
    }
  }
  return reply;
}

function addChat(input,product) {
  const messagesContainer = document.getElementById("messages");

  let userDiv = document.createElement("div");
  userDiv.id = "user";
  userDiv.className = "user response";
  userDiv.innerHTML = `<span>${input}</span>`;
  messagesContainer.appendChild(userDiv);

  let botDiv = document.createElement("div");
  let botImg = document.createElement("img");
  let botText = document.createElement("span");
  botDiv.id = "bot";
  botImg.src = "";
  botImg.className = "avatar";
  botDiv.className = "bot response";
  botText.innerText = "Moment,ich berechne die Antwort...";
  botDiv.appendChild(botText);
  botDiv.appendChild(botImg);
  messagesContainer.appendChild(botDiv);
  // Keep messages at most recent
  messagesContainer.scrollTop = messagesContainer.scrollHeight - messagesContainer.clientHeight;

  // Fake delay to seem "real"
  setTimeout(() => {
    botText.innerText = `${product}`;
    textToSpeech(product)
  },2000
  )
