function formatHTML(content, length = 20){ let result = ""; // 内容过长换行 do{ result += content.substring(0, length) + "<br/>"; content = content.substring(length); }while(content.length > length); result += content; result = result.replaceAll(" ", "&nbsp;"); // 换行符替换 result = result.replaceAll("\n", "<br/>"); return result; } 修改上述代码，增添如下功能，可以在聊天界面连续问答。 其中： 1. 一个问题未回答前，不能发送下一个问题 2. 因任何原因无法正确响应的，要提示错误并做标记

下面是修改后的代码，增加了连续问答的功能，并在无法正确响应时进行错误提示和标记。

function formatHTML(content, length = 20){
        let result = "";
        // 内容过长换行
        do{
            result += content.substring(0, length) + "<br/>";
            content = content.substring(length);
        }while(content.length > length);

        result += content;
        result = result.replaceAll(" ", "&nbsp;");
        // 换行符替换
        result = result.replaceAll("\n", "<br/>");
        return result;
    }

// 定义问题和回答
const chatData = [
    {question: "What is your name?", answer: "My name is ChitGPT."},
    {question: "How old are you?", answer: "I am an AI, I don't have an age."},
    {question: "What is the meaning of life?", answer: "The meaning of life is subjective and can vary for each individual."},
    // 添加更多问题和回答
];

// 记录当前问题索引和是否已回答标记
let currentQuestionIndex = 0;
let isQuestionAnswered = true;

// 处理用户输入问题的函数
function handleUserInput(question) {
    if (!isQuestionAnswered) {
        // 如果上一个问题未回答，提示错误并做标记
        console.log("Error: Please wait for the previous question to be answered.");
        return;
    }

    // 查找当前问题的回答
    const currentQuestion = chatData[currentQuestionIndex];
    if (!currentQuestion) {
        // 如果问题索引超出范围，提示错误并做标记
        console.log("Error: No more questions available.");
        return;
    }

    // 检查用户输入的问题是否匹配当前问题
    if (question.toLowerCase().includes(currentQuestion.question.toLowerCase())) {
        // 回答匹配的问题
        const answer = currentQuestion.answer;
        console.log("Answer: " + answer);

        // 标记问题已回答
        isQuestionAnswered = true;

        // 增加问题索引，准备回答下一个问题
        currentQuestionIndex++;
    } else {
        // 如果问题不匹配，提示错误并做标记
        console.log("Error: Incorrect question. Please ask the correct question.");
    }
}

// 测试连续问答
handleUserInput("What is your name?");
handleUserInput("How old are you?");
handleUserInput("What is the meaning of life?");
handleUserInput("Incorrect question");
handleUserInput("What is the meaning of life?");

请注意，这只是一个简单的示例代码，仅用于演示连续问答的思路。在实际应用中，可能需要根据具体需求进行更复杂的逻辑设计和错误处理。
