Newbie: working in a loop 1

[kconmle]

I have no ruby experience - can anyone give me some guidance:

I have a loop where I am outputting a row of a table i.e.

<% for lef in @lefs %>
<tr>
<td></td>
</tr>
<%end%>

I want to have an if-else in there where I can change the class of the td. How would I go about that?

Hi

For example to create a table with the letters of the alphabet, applying the appropriate [tt]class[/tt] of 'vowel' or 'consonant' to the [tt]tr[/tt] of each letter :

<%

@lefs=('a'..'z').to_a
vowel='aeiou'

%>

<table>

<% for lef in @lefs %>
<tr class="<%=vowel.index(lef)?'vowel':'consonant' %>">
  <td><%=lef %></td>
</tr>
<% end %>

</table>

Or if you want an example with the use of an [tt]if[/tt] statement, this outputs only the vowels :

<%

@lefs=('a'..'z').to_a
vowel='aeiou'

%>

<table>

<% for lef in @lefs %>
  <% if vowel.index lef %>
<tr>
  <td><%=lef %></td>
</tr>
  <% end %>
<% end %>

</table>
