alert when option from dropdown menu is selecteed

[leonk09]

hi all,

I really don't know much about javascripts (I know how to cut an paste them, but not much else).

I have a mail form, which already has plenty of javascript on there for validation.

One of the sections of my form is a dropdown menu. I need an alert box with a message to appear when a specific value is selected:

Here's the dropdown menu:

<SELECT name="lst_fn_9">
<option value="NOT SELECETED" selected>Please Select</option>
<option value="value 1" >Value 1</option>
<option value="Value 2" >Value 2</option>

So say for example somebody selects "value 2", I want an alert window to appear immedialtey on selection.

How would I go about doing this?

many thanks

use the onchange handler on the select box:

<script type="text/javascript">

function msg(obj) {
   if (obj.selectedIndex == 2) {
      alert("you have selected option 2");
   }
}

</script>
<select name="lst_fn_9" [b][COLOR=red]onchange="msg(this)"[/color][/b]>
<option value="NOT SELECETED" selected>Please Select</option>
<option value="value 1" >Value 1</option>
<option value="Value 2" >Value 2</option>
</select>
