多次点击提交按钮后重复出现问题

// 防抖示例
function debounce(func, wait) {
    let timeout;
    return function(...args) {
        clearTimeout(timeout);
        timeout = setTimeout(() => func.apply(this, args), wait);
    };
}

document.getElementById('submitBtn').addEventListener('click', debounce(() => {
    // 提交逻辑
}, 1000));

    # 处理请求逻辑
