Hi Friend,
Try the following code:
<html>
<h2>ComboBox</h2>
<script language="javascript">
var arr = new Array();
arr[0] = new Array("-select-");
arr[1] = new Array("Nokia","Sony","Motorola","Samsung");
arr[2] = new Array("Titan","HMT");
arr[3] = new Array("Liberty","Action","Bata");
arr[4] = new Array("Mercedes","Toyoto","Maruti","Innovo");
function change(combo1)
{
var comboValue = combo1.value;
document.forms["form"].elements["combo2"].options.length=0;
for (var i=0;i<arr[comboValue].length;i++)
{
var option = document.createElement("option");
option.setAttribute('value',i+1);
option.innerHTML = arr[comboValue][i];
document.forms["form"].elements["combo2"].appendChild(option);
}
}
</script>
<form name="form" method="post">
<select name="combo1" onchange="change(this);">
<option value="0">-Select-</option>
<option value="1">Mobiles</option>
<option value="2">Watches</option>
<option value="3">Shoes</option>
<option value="4">Cars</option>
</option>
