jquery - How do I make my div IDs variable in rails? -

-

i feel there should simple way this, don't know is. have list of data display, , want include ajax "read more" function expand information @ bottom of each segment. this, need unique div ids within each segment. have code:

<% choice in @student_choices %>     <div id= "student_description", style="display:none;">         <%= choice[:description]%>     </div>     <%= link_to_function "read more", "element.show("student_description")"%> <% end %>

but since there multiple div ids, clicking "read more" displays first one. how insert variable div id? know how in php, has me stumped. if div id variable, how element.show accept variable?

you can like:

<% div_id = "student_description_#{choice.id}" -%>  <div id="<%= div_id -%>", style="display:none;">     <%= choice.description %> </div>  <%= link_to_function "read more", "element.show('##{div_id}')" %>
