    Default XJOSS SCRIPT - Membuat ComboBOX Bertingkat PHP

    Xjoss Script - Berikut ini ada sedikit tips bagaimana membuat sebuah combobox bertingkat menggunakan ajax...,

    ComboBox bertingkat dalam artian, nilai combobox yang satu dipengaruhi oleh nilai pilihan pada combobox sebelumnya, misalnya:

    - pada combobox pertama dipilih propinsi BALI, nah pada combobox berikutnya akan tampil kota-kota khusus di BALI, misalnya DENPASAR, SINGARAJA dsb.

    - kemudian misalkan lanjut dr hal diatas, dipilih kota DENPASAR, maka pada combobox berikutnya akan muncul alamat-alamat rumah, kantor atau sebagainya khusus area DENPASAR...

<!-- ------------------------------------------- -->

<script type='text/javascript'>
function createRequestObject() {
    var ro;
    var browser = navigator.appName;
    if(browser == "Microsoft Internet Explorer"){
        ro = new ActiveXObject("Microsoft.XMLHTTP");
    }else{
        ro = new XMLHttpRequest();
    }
    return ro;
}

var xmlhttp = createRequestObject();

function rubah(combobox)
{
    var kode = combobox.value;
    if (!kode) return;
    xmlhttp.open('get', 'ambildata.php?kode='+kode, true);
    xmlhttp.onreadystatechange = function() {
        if ((xmlhttp.readyState == 4) && (xmlhttp.status == 200))
             document.getElementById("divkedua").innerHTML = xmlhttp.responseText;
			 document.getElementById("divketiga").innerHTML = "";
        return false;
    }
    xmlhttp.send(null);         
}

function rubah2(combobox)
{
    var kode2 = combobox.value;
    if (!kode2) return;
    xmlhttp.open('get', 'ambildata2.php?kode='+kode2, true);
    xmlhttp.onreadystatechange = function() {
        if ((xmlhttp.readyState == 4) && (xmlhttp.status == 200))
             document.getElementById("divketiga").innerHTML = xmlhttp.responseText;
        return false;
    }
    xmlhttp.send(null);         
}

</script>
</body>
</html>


    2. Buat file ambildata.php
    Spoiler:

    Code:
    <?
$kode = $_GET['kode'];

if ($kode == "BALI")
{
?>
<select name="kota" onChange="javascript:rubah2(this)">
<option value="DENPASAR">DENPASAR</option>
<option value="SINGARAJA">SINGARAJA</option>
</select>

<?
}
else if ($kode == "JATIM")
{
?>	
<select name="kota" onChange="javascript:rubah2(this)">
<option value="SURABAYA">SURABAYA</option>
<option value="SIDOARJO">SIDOARJO</option>
</select>
<?
}
else if ($kode == "JABAR")
{
?>	
<select name="kota" onChange="javascript:rubah2(this)">
<option value="JAKARTA">JAKARTA</option>
<option value="BOGOR">BOGOR</option>
</select>
<?
}
?>






    3. Buat ambildata2.php
    Spoiler:

    Code:
    <?php
//By XJOSS.NET - EXTREME ZONE

$kode = $_GET['kode'];

if ($kode == "DENPASAR")
{
?>
<select name="alamat">
<option value="">XJOSS.NET DENPASAR</option>
<option value="">TEUKU UMAR</option>
<option value="">IMAM BONJOL</option>
</select>

<?
}
else if ($kode == "SINGARAJA")
{
?>	
<select name="alamat">
<option value="">XJOSS.NET SINGARAJA</option>
<option value="">A YANI</option>
<option value="">DIPONEGORO</option>
</select>
<?
}
else if ($kode == "SURABAYA")
{
?>	
<select name="alamat">
<option value="">XJOSS.NET SURABAYA</option>
<option value="">A YANI</option>
<option value="">DIPONEGORO</option>
</select>
<?
}
else if ($kode == "SIDOARJO")
{
?>	
<select name="alamat">
<option value="">XJOSS.NET SIDOARJO</option>
<option value="">A YANI</option>
<option value="">DIPONEGORO</option>
</select>
<?
}
else if ($kode == "JAKARTA")
{
?>	
<select name="alamat">
<option value="">XJOSS.NET JAKARTA</option>
<option value="">A YANI</option>
<option value="">DIPONEGORO</option>
</select>
<?
}
else if ($kode == "BOGOR")
{
?>	
<select name="alamat">
<option value="">XJOSS.NET BOGOR</option>
<option value="">A YANI</option>
<option value="">DIPONEGORO</option>
</select>
<?
}
?>


    Note: ComboBOX bisa dibuat lebih dari contoh ini, kuncinya pada script berikut
    Spoiler:

    Code:
    function rubah(combobox)
{
    var kode = combobox.value;
    if (!kode) return;
    xmlhttp.open('get', 'ambildata.php?kode='+kode, true);
    xmlhttp.onreadystatechange = function() {
        if ((xmlhttp.readyState == 4) && (xmlhttp.status == 200))
             document.getElementById("divkedua").innerHTML = xmlhttp.responseText;
			 document.getElementById("divketiga").innerHTML = "";
        return false;
    }
    xmlhttp.send(null);         
}

dan

<div id="divkedua"></div>

dan

<select name="propinsi" onChange="javascript:rubah(this)">
  <option value="BALI">BALI</option>
  <option value="JATIM">JATIM</option>
  <option value="JABAR">JABAR</option>
</select>
    Perhatikan pada huruf yang berwarna merah.....
