【问题描述】:
当我使用appendChild() 更新 HTML 表格时,整个表格被移动到文档的底部。如何在 DOM 中保留表格的位置?
我的示例也发布在JSFiddle。
<!--I want the existing table below to stay fixed in place after new rows are added.-->
<table id="table">
<tr>
<td> Table Cell 1</td>
<td> Table Cell 2</td>
</tr>
</table>
<!--The following button will add rows, but also move the table. How do I stop the move?-->
<input type="button" value="ADD NEW ROWS." onclick="generate_table()">
<script>
// This function just creates new rows for the table
function generate_table() {
var body = document.getElementsByTagName("body")[0];
var tbl = document.getElementById("table");
var tblBody = document.createElement("tbody");
for (var i = 0; i < 2; i++) {
var row = document.createElement("tr");
for (var j = 0; j < 2; j++) {
var cell = document.createElement("td");
var cellText = document.createTextNode("cell " + i + ", column " + j);
cell.appendChild(cellText);
row.appendChild(cell);
}
tblBody.appendChild(row);
}
tbl.appendChild(tblBody);
body.appendChild(tbl);
}
</script>
<style>
table,
th,
td {
border: 1px solid black;
border-collapse: collapse;
}
</style>
