猜数字游戏

请输入一个1-100之间的数字：

index.js

const randomNumber = Math.floor(Math.random() * 100) + 1;
let count = 0;
const history = document.getElementById('history');
function checkGuess() {
    const userGuess = parseInt(document.getElementById('userGuess').value);
    if (isNaN(userGuess) || userGuess < 1 || userGuess > 100) {
        document.getElementById('userResult').textContent = '请输入一个有效的数字（1-100）';
        return;
    }
    count++;
    let message = '';
    if (userGuess === randomNumber) {
        message = `恭喜您，猜对啦，一共用了${count}次`;
        document.getElementById('userGuess').disabled = true;
        document.querySelector('button').disabled = true;
    }
    else if (userGuess < randomNumber) {
        message = `对不起，您猜小了，请继续猜测`;
    }
    else {
        message = `对不起，您猜大了，请继续猜测`;
    }
    document.getElementById('userResult').textContent = message;
    document.getElementById('count').textContent = `猜测次数${count}`;
    const li = document.createElement('li');
    li.textContent = `第${count}次猜测：${userGuess}  ${message}`;
    history.appendChild(li);
    document.getElementById('userGuess').value = '';
}
function refresh(){
        location.reload()
    
}
