Rails 2.3.5, Ruby 1.86
I haven't been able to figure this out. The 'onchange' in the select below is not being written (no onchange written in the HTML). I haven't seen a reference to the syntax being different except in some older examples the onchange is surrounded in brackets:
<%= f.select :directory_id, options_for_select(@directories, @directory_to_select), :onchange => 'folder_lookup()' %>
results in:
<select id="contact_directory_id" name="contact[directory_id]">
<option value="2">test_1</option>
<option value="4">test_2</option>
<option value="33" selected="selected">test_3</option>
</select>
If I simply change "f.select" to "select_tag" the onchange is written correctly (not that I want to do that though):
<%= select_tag :directory_id, options_for_select(@directories, @directory_to_select), :onchange => 'folder_lookup()' %>
results in:
<select id="contact_directory_id" name="directory_id" onchange="folder_lookup()">
<option value="2">test_1</option>
<option value="4">test_2</option>
<option value="33" selected="selected">test_2</option>
</select>
Am I missing a syntax difference for onchange between a select and select_tag helper?
Thanks!
This is what you want:
<%= f.select :directory_id, options_for_select(@directories, @directory_to_select), {}, :onchange => 'folder_lookup()' %>
With select the method signature looks like this select(object, method, choices, options = {}, html_options = {})
. onchange is an html_option, since you don't have any options, you need an empty hash so that your last onchange is taken as an html_option.
