Menu
I have 2 different SELECT OPTION in a form.
The first one is Source, the second one is Status. I would like to have different OPTIONS in my Status drop-down list depending on the OPTION selected in my Source drop-down.
Source:
<select id="source" name="source">
<option>MANUAL</option>
<option>ONLINE</option>
</select>
Status:
<select id="status" name="status">
</select>
Options: - If Source is MANUAL, then Status is OPEN or DELIVERED - If Source is ONLINE, then Status is OPEN or DELIVERED or SHIPPED
My non-working attempt:
<script>
$(document).ready(function () {
var option = document.getElementById("status").options;
if (document.getElementById('source').value == "MANUAL") {
$("#status").append('<option>OPEN</option>');
$("#status").append('<option>DELIVERED</option>');
}
if (document.getElementById('source').value == "ONLINE") {
$("#status").append('<option>OPEN</option>');
$("#status").append('<option>DELIVERED</option>');
$("#status").append('<option>SHIPPED</option>');
}
});
</script>

You will have to simply execute the script named CreateCascadingDatabase. sql stored in the SQL Folder of the attached sample and it will create the complete database with data. Below is the HTML Markup which contains three ASP.Net DropDownList controls each for Country, State and City.
Go to Data > Data Validation. On the Settings tab, click in the Source box, and then on the worksheet that has the entries for your drop-down list, Select cell contents in Excel containing those entries. You'll see the list range in the Source box change as you select.
Create three dropdown lists, inside an HTML form. The second and third dropdown list will display different options, depending on the value selected in the parent dropdown list.
Try something like this... jsfiddle demo
HTML
<!-- Source: -->
<select id="source" name="source">
<option>MANUAL</option>
<option>ONLINE</option>
</select>
<!-- Status: -->
<select id="status" name="status">
<option>OPEN</option>
<option>DELIVERED</option>
</select>
JS
$(document).on('ready', function () {
$("#source").on('change', function () {
var el = $(this);
if (el.val() === "ONLINE") {
$("#status").append("<option>SHIPPED</option>");
} else if (el.val() === "MANUAL") {
$("#status option:last-child").remove();
}
});
});
I am posting this answer because in this way you will never need any plugin like jQuery and any other, This has the solution by simple javascript.
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script language="javascript" type="text/javascript">
function dynamicdropdown(listindex)
{
switch (listindex)
{
case "manual" :
document.getElementById("status").options[0]=new Option("Select status","");
document.getElementById("status").options[1]=new Option("OPEN","open");
document.getElementById("status").options[2]=new Option("DELIVERED","delivered");
break;
case "online" :
document.getElementById("status").options[0]=new Option("Select status","");
document.getElementById("status").options[1]=new Option("OPEN","open");
document.getElementById("status").options[2]=new Option("DELIVERED","delivered");
document.getElementById("status").options[3]=new Option("SHIPPED","shipped");
break;
}
return true;
}
</script>
</head>
