我在页面上有以下 JavaScript 函数：
function setFields(){
var menu = document.getElementById('EditLocation');
var itemDataArray = menu[menu.selectedIndex].value.split('|');
form.LocationShortName.value = itemDataArray[0];
form.LocationLongName.value = itemDataArray[1];
form.Phone.value = itemDataArray[2];
form.Address1.value = itemDataArray[3];
form.CityStateZip.value = itemDataArray[4];
form.MapLink.value = itemDataArray[5];
}
在表格上，我有以下内容：
<select class="input2" name="EditLocation" id="EditLocation" onchange = "setFields();">
<option value="-Add New-"<?php if($editlocation=='-Add New-'){echo(' selected="selected"');} ?>>-Add New-</option>
<?php require_once('connection.php');
$connection = mysql_connect($hostname,$username,$password) or die (mysql_errno().": ".mysql_error()."<BR />");
mysql_select_db($database);
$sql = "SELECT * FROM directions ORDER BY dirshortname";
$query = mysql_query($sql);
while ($row = mysql_fetch_array($query)) {
echo('<option value="'.stripslashes($row['dirshortname']).'|'.stripslashes($row['dirlongname']).'|'.stripslashes($row['dirphone']).'|'.stripslashes($row['dirstreet']).'|'.stripslashes($row['dircsz']).'|'.stripslashes($row['dirmaplink']).'"');
if ($editlocation==stripslashes($row['dirshortname']))
{
echo(' selected="selected"');
}
echo('>'.stripslashes($row['dirshortname']).'</option>');
}
?>
本质上，PHP 应该将从 MySQL 中提取的数据元素打包到 SELECT 框的 OPTION VALUE 部分。一旦用户选择了一条记录，JavaScript 就会将打包的数据分开并填充 FORM 上的其他数据元素。这一切都在 IE 中运行得很好，但在 FF 中，字段不会填充数据。
表格有点长，但为了完整起见，我还是会包含它。
