纯JS中表格元素的下一步/上一步按钮

// 示例代码：绑定事件监听器
document.getElementById('nextBtn').addEventListener('click', function() {
    console.log('Next button clicked');
    // 执行下一步逻辑
});

document.getElementById('prevBtn').addEventListener('click', function() {
    console.log('Previous button clicked');
    // 执行上一步逻辑
});

// 示例代码：简单的导航逻辑
let currentIndex = 0;
const dataRows = document.querySelectorAll('table tr');

document.getElementById('nextBtn').addEventListener('click', function() {
    if (currentIndex < dataRows.length - 1) {
        currentIndex++;
        updateTableDisplay();
    }
});

document.getElementById('prevBtn').addEventListener('click', function() {
    if (currentIndex > 0) {
        currentIndex--;
        updateTableDisplay();
    }
});

function updateTableDisplay() {
    // 根据currentIndex更新表格显示内容
}
