How to add onchange javascript event to select field

I would like to add javascript ‘onChange’ event handling for a select
field, such as
<%= collection_select(“job”, “client_id” , @clients, “id”, “name”) %>
with onChange=“xxx”

Anyone know how to make this work?
Thank you,
Scott

http://rubyonrails.org/api/classes/ActionView/Helpers/FormOptionsHelper.html#M000352

The full API is:

collection_select(object, method, collection, value_method,
text_method, options = {}, html_options = {})

Just add :onchange => “xxx” to the html_options and you are set.

Berin,
Thank you for responding. I cannot get the syntax correct. Would it be
something like:
<%= collection_select(“job”, “client_id” , @clients, “id”, “name”,
html_options = {:onchange => “alert(‘hello’)”} )%>

or

<%= collection_select(“job”, “client_id” , @clients, “id”, “name”,
{:onchange => “alert(‘hello’)”} )%>

Berin,
Thank you, that worked!

know if there is a way to know the id or the customer has selected??

this will give you the selected text if you want it. you can probably
figure out what you need from this example.

var grain = $(‘select#id_of_my_element option:selected’).text();

You have to get past the “options” parameter before you can use
“html_options”

<%= collection_select(“job”, “client_id” , @clients, “id”, “name”, {},
{:onchange => “alert(‘hello’)”} )%>
