Dropdown When Changed Client Side Event

The dropdown field only supports client-side event handlers for On Field Entry and On Field Exit. I'd like to execute a client-side script on a change, so it will need to be a hack. If anyone has a solution, please pass it along.

Hi Rob

Try this:

$addHandler(
    $get("MyDropdownField"), 
    'change', 
    function()
    {
        // do something when the dropdown value changes...
        alert( "Dropdown changed!" );
    });

Hi Iain,are you sure, it works? Shoul I run it on form load?

This works for "click" event, but not work for "change" like in your example.

Hi Greg

Apologies, my previous example only worked with Firefox.

This should work with both browsers (tested with Firefox 11 and IE 8)

$addHandler(
    $find('MyDropdownField').radComboBox.get_inputDomElement(), 
    'change', 
    function()
    {
        // do something when the dropdown value changes...
        alert( 'Dropdown changed!' );
    });

Thanks

Seems like this isn't working for me. It doesn't seem to like the argument

$find('MyDropdownField').radComboBox.get_inputDomElement(),

I'm on IE9 using BPM v9.1.2.1. What version of BPM are you using?

I'm also using 9.1.2.1

I've attached the sample that works for me on IE 8 (in compatibility mode) and Firefox 11

Wow! That was annoying. When I copy and paste from your solution it works like a charm, but when I do so from your post that gives an 'invalid character' error when loading the script. Evidently, there is a hidden character between 'E' and 'l' in '

get_inputDomElement' of your original post.
