Javascript: Select Options [Resolved]
Hi,
I've 2 select boxes. When the user changes the option in the first select box, the options in the second select box will change/populated.
I used the onchange event on the first select box, but the options in the second select box is not populated.
My codes:
Code:
<html>
<head>
<script language="Javascript">
var NW = new Array("Network/User Admin", "Hardware", "Software");
var BA = new Array("Email", "Intranet");
function main_change(mymain) {
var _main = mymain.value;
if (_main == "NW") {
for (var k=0; k< NW.length; k++) {
OPT = new Option;
OPT.Text= NW[k];
OPT.Value= NW[k];
document.forms['issue']['subCat'].options[k] = OPT;
}
}
else if (_main == "BA") {
for (var k=0; k< BA.length; k++) {
OPT = new Option;
OPT.Text= NW[k];
OPT.Value= NW[k];
document.forms['issue']['subCat'].options[k] = OPT;
}
}
}
</script>
</head>
<body>
<form name="issue">
<table>
<tr>
<td>Main Category:</td>
<td width=10> <select name="main" onchange="main_change(this);">
<option>Please Choose One...</option>
<option value="NW">Network</option>
<option value="BA">Business App</option>
</select>
</td>
<td>Sub Category:</td>
<td> <select name="subCat">
<option>Please Choose One...</option>
</select>
</td>
</tr>
</table>
</form>
</body>
</html>
