Adding javascript onchange event on select tag

Hi,
I am writing following code for showing the drop down:-
<%= select("test", "type", ["test1", "test2"],
:onchange=>"alert('Test');")%>

My problem is I have to add onchange event and call a javascript.
Can anyone point me what is problem with my syntex?

Thanks,

Easy one…

The first hash is Select options, the second is HTML options. So you’re passing :onchange through as an option to the Rails helper, rather than having it pass through to an HTML attribute. What you want to do is this:

<%= select(“test”, “type”, [“test1”, “test2”], {}
{:onchange=>“alert(‘Test’);”} )%>

Note the empty {} after your normal parameter, that’s the empty select options, then your :onchange is in the HTML options hash.
