我有一堆同名的元素,我试图用 onchange 函数同时删除它们。
这是javascript:
<script type="text/javascript">
function removeoldAccounts() {
var e = document.getElementById("account_table")
var accounts = document.getElementsByName("extraaccounts");
e.removeChildren(accounts);
}
</script>
(甚至不确定 removeChildren 是否是一个真正的命令)以及我将 onchange 操作赋予的元素:
<select id="piname" name="pi_name" onChange="removeoldAccounts" />
我试图删除的元素:
<tbody id="account_table">
<tr>
<td>Account Number<span>*</span>:</td>
<td id="accounts">
<select id="accountnum" name="account_number">
<option value="5636745946254">5636745946254</option>
<option value="23164847322">23164847322</option>
</select>
</td>
<td>
<input type="hidden" id="theValue3" value="81">
<input type="button" value="Add More" onclick="addaccount()">
</td>
</tr>
<tr id="80" name="extraaccount">
<td>
<select id="80" name="account_number">
<option value="5636745946254">5636745946254</option>
<option value="23164847322">23164847322</option>
</select>
</td>
<td>
<input type="text" size="20" name="account_comment80">
</td>
<td>
<input type="button" onclick="removeaccount(80)" value="remove">
</td>
</tr>
<tr id="81" name="extraaccount">
<td>
<select id="81" name="account_number">
<option value="5636745946254">5636745946254</option>
<option value="23164847322">23164847322</option>
</select>
</td>
<td>
<input type="text" size="20" name="account_comment81">
</td>
<td>
<input type="button" onclick="removeaccount(81)" value="remove">
</td>
</tr>
</tbody>
抱歉,如果 html 有点草率,但基本上,atbody
有一堆td
同名的 s (extraaccount)
