html部分
<!DOCTYPE html>

<head><title>表格示例</title>
</head>
<body><table border="1"><thead><tr><th>更新时间</th><th>操作</th></tr></thead><tbody id="tableBody"><!-- 这里是虚拟数据行，你可以根据需要添加更多 --><tr><td>2023-10-13 10:00 ---- PM</td><td><button onclick="moveUp(this)">上移</button><button onclick="moveDown(this)">下移</button><button onclick="moveToTop(this)">置顶</button><button onclick="moveToBottom(this)">置底</button><button onclick="removeRow(this)">删除</button></td></tr><tr><td>2023-10-13 02:30 ---- AM</td><td><button onclick="moveUp(this)">上移</button><button onclick="moveDown(this)">下移</button><button onclick="moveToTop(this)">置顶</button><button onclick="moveToBottom(this)">置底</button><button onclick="removeRow(this)">删除</button></td></tr></tbody></table><button onclick="addRow()">添加数据行</button><script>//添加行function addRow() {var tableBody = document.getElementById("tableBody");var newRow = document.createElement("tr");newRow.innerHTML = `<td>${getCurrentTime()+'----'+Math.round(Math.random()*100+1)}</td><td><button onclick="moveUp(this)">上移</button><button onclick="moveDown(this)">下移</button><button onclick="moveToTop(this)">置顶</button><button onclick="moveToBottom(this)">置底</button><button onclick="removeRow(this)">删除</button></td>`;tableBody.appendChild(newRow);}//移除行function removeRow(button) {var row = button.parentNode.parentNode;row.remove();}function getCurrentTime() {var now = new Date();var year = now.getFullYear();var month = (now.getMonth() + 1).toString().padStart(2, '0');var day = now.getDate().toString().padStart(2, '0');var hours = now.getHours().toString().padStart(2, '0');var minutes = now.getMinutes().toString().padStart(2, '0');var time = `${year}-${month}-${day} ${hours}:${minutes}`;return time;}</script>
</body>
</html>上移
function moveUp(button) {var row = button.parentNode.parentNode;if (row.previousElementSibling) {console.log("🚀 ~ file: tabel.html:67 ~ moveUp ~ row.previousElementSibling:", row.previousElementSibling)row.parentNode.insertBefore(row, row.previousElementSibling);}}
下移
function moveDown(button) {var row = button.parentNode.parentNode;if (row.nextElementSibling) {console.log("🚀 ~ file: tabel.html:74 ~ moveDown ~ row.nextElementSibling:", row.nextElementSibling)row.parentNode.insertBefore(row.nextElementSibling, row);}}
置顶
function moveToTop(button) {var row = button.parentNode.parentNode;var tableBody = row.parentNode;tableBody.insertBefore(row, tableBody.firstElementChild);}
置底
function moveToBottom(button) {var row = button.parentNode.parentNode;var tableBody = row.parentNode;tableBody.appendChild(row);}这篇关于简单实现一个todoList（上移、下移、置顶、置底）的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
