แบบนี้ครับ Go to : JavaScript Fixed Size and Get Size in HTML Element
Code (JavaScript)
<!DOCTYPE html>
<html>
<head>
</head>
<script language="JavaScript">
function fnc5Rows()
{
var ele = document.getElementById('ddlProvince');
ele.size = "5";
}
function fnc10Rows()
{
var ele = document.getElementById('ddlProvince');
ele.size = "10";
}
function fnc15Rows()
{
var ele = document.getElementById('ddlProvince');
ele.size = "15";
}
</script>
<body>
<input type="button" value="5 Rows" OnClick="fnc5Rows()">
<input type="button" value="10 Rows" OnClick="fnc10Rows()">
<input type="button" value="15 Rows" OnClick="fnc15Rows()"><br />
<select name="ddlProvince" size="20" id="ddlProvince" style="width:120px" >
</body>
</html>
ของคุณก็น่าจะเป็น
Code (JavaScript)
<script language = "JavaScript">
//**** List Province (Start) ***//
function ListProvince(SelectValue)
{
frmMain.ddlProvince.length = 0
<?
$intRows = 0;
$strSQL = "SELECT * FROM province ORDER BY PROVINCE_ID ASC ";
$objQuery = mysql_query($strSQL) or die ("Error Query [".$strSQL."]");
$intRows = 0;
while($objResult = mysql_fetch_assoc($objQuery))
{
$intRows++;
?>
x = <?=$intRows;?>;
mySubList = new Array();
strGroup = <?=$objResult["GEO_ID"];?>;
strValue = "<?=$objResult["PROVINCE_ID"];?>";
strItem = "<?=$objResult["PROVINCE_NAME"];?>";
mySubList[x,0] = strItem;
mySubList[x,1] = strGroup;
mySubList[x,2] = strValue;
if (mySubList[x,1] == SelectValue){
var myOption = new Option(mySubList[x,0], mySubList[x,2])
frmMain.ddlProvince.options[frmMain.ddlProvince.length]= myOption
}
<?
}
?>
var ele = document.getElementById('ddlProvince');
ele.size = "<?=$intRows;?>";
}
//**** List Province (End) ***//
</script>

แก้ใหม่ครับ
Code (JavaScript)
<script language = "JavaScript">
//**** List Province (Start) ***//
function ListProvince(SelectValue)
{
frmMain.ddlProvince.length = 0;
var i = 0;
<?
$intRows = 0;
$strSQL = "SELECT * FROM province ORDER BY PROVINCE_ID ASC ";
$objQuery = mysql_query($strSQL) or die ("Error Query [".$strSQL."]");
$intRows = 0;
while($objResult = mysql_fetch_assoc($objQuery))
{
$intRows++;
?>
x = <?=$intRows;?>;
mySubList = new Array();
strGroup = <?=$objResult["GEO_ID"];?>;
strValue = "<?=$objResult["PROVINCE_ID"];?>";
strItem = "<?=$objResult["PROVINCE_NAME"];?>";
mySubList[x,0] = strItem;
mySubList[x,1] = strGroup;
mySubList[x,2] = strValue;
if (mySubList[x,1] == SelectValue){
i++;
var myOption = new Option(mySubList[x,0], mySubList[x,2])
frmMain.ddlProvince.options[frmMain.ddlProvince.length]= myOption
}
<?
}
?>
var ele = document.getElementById('ddlProvince');
ele.size = i;
}
//**** List Province (End) ***//
</script>
