输入输入字段后,我在给定的“id”上附加了一行,但它没有附加。
function myfunction() {
var obj = "<tr><td>" + document.getElementById("name").value + "</td><td>" + document.getElementById("num").value + "</td><td>" + document.getElementById("address").value + "</td></tr>";
document.getElementById("table").innerHTML = obj;
}
<table>
<tr>
<td>Name: <input type="text" id="name"></td>
<td>Age:<input type="number" id="num"></td>
<td>Address:<input type="text" id="address"></td>
<td><input type="button" onclick="myfunction()" value="click on me"></td>
</tr>
<tbody id="table">
</tbody>
</table>
