我正在尝试将由管道分隔的值发送到2个不同的字段。由于某种原因,它将无法正常工作。
有任何想法吗?
<script type="text/javascript">
function folder(selectVeld)
{
// Stuur informatie terug
var id = (selectVeld.options[selectVeld.selectedIndex].value).split('|');
// Id
document.getElementsByName('folder_id').value = id[0];
// Naam
document.getElementsByName('folder_naam').value = id[1];
}
</script>
<tr>
<td><?php echo $lang['folder']; ?>:</td>
<td><select name="folder" onChange="folder(this)">
<option value="geen"><?php echo $lang['no_folder']; ?></option>
<?php
$sql = "SELECT id, naam FROM 2_folder ORDER BY naam ASC";
$res = mysql_query($sql,$con);
while ($row = mysql_fetch_assoc($res)){
?>
<option <?php if($row['id'].'|'.$row['naam'] == $folder){ echo 'selected="selected"'; } ?> value="<?php echo $row['id'].'|'.$row['naam']; ?>"><?php echo $row['naam'] ?></option>
<?php } ?></select>
</td>
</tr>
<input type="text" name="folder_id" value="<?php echo $folder_id; ?>" size="5" style="background-color: #e7e7e9" readonly="readonly" />
<input type="text" name="folder_naam" value="<?php echo $folder_naam; ?>" size="5" style="background-color: #e7e7e9" readonly="readonly" />
最佳答案
document.getElementsByName
返回元素的array
,即使只有一个具有该名称的元素也是如此。
document.getElementsByName('folder_id')[0].value = id[0];
document.getElementsByName('folder_naam')[0].value = id[1];
应该可以。 jsfiddle sample
