I am trying to create a view/form that has a dropdown
<p>
<%= f.label :type_id%><br />
<%= f.select :type_id,Type.all.collect{|c| [c.description,c.id]},
:onchange=>"HERE I NEED TO DO SOMETHING WHAT?" %>
<!-- on change or on select show drop down for value otherwise
regular value -->
</p>
Now when they change and the id is now 5
HERE I NEED TO CHECK THE VALUE SELECTED BY THE FIRST SELECT
1. How do I access the id of the first select and what was selected?
I want to create:
<p>
<%= f.label :value %>
<%= f.select :value,Test.get_tests.all.collect{|c|
[c.description,c.test_id]} %>
</p>
If its not 5
I want
<p>
<%= f.label :value %><br />
<%= f.text_field :value %>
Please if you can tell me how to access the first select- do I set an
id? and what I do onchange since its in the same form a few lines down I
want to have a different field.
Thank you

Try a google search on ''rails observe_field select''. HTH, Bill

Two things: Every post I see determines a second select based on the first select. What I am trying to do is based on the first select either display a second select or display a text field(this will depend on the first select value) I tried to use the observe field and I am not sure of two things: the action=> ''funtion'' Do I need to create in the controller any function and if yes what? basically if there is a change in the select, I want to check the value if it equals 5, display a second select, if not display text field. Also what does the parameter :with do? The :update=> "myfield name" this field should be the second select name and then how to I display the text field instead? -- Posted via http://www.ruby-forum.com/.
Is this what you''re trying to do? http://railscasts.com/episodes/88-dynamic-select-menus
Lee Smith wrote:> Is this what you''re trying to do? > > http://railscasts.com/episodes/88-dynamic-select-menusThank you, Its similar. But all these posts are telling me based on one select to populate a second select. What if based on one select, I want to determine the other field- if its select or if its a text field. I am very new to Ruby on Rails and I am not sure how to go about this. Thank you -- Posted via http://www.ruby-forum.com/.
