Dynamic element in Jade with String and a variable

Question

I have a variable for example named "elem" , "elem" may be head, body and foot;

I want to create html element with for example;

if elem == "body"
  "t" + elem => tbody html element 
if elem == "head"
  "t" + elem => thead html element 
if elem == "foot"
  "t" + elem => tfoot element 

I tried many combination but not able to that. How can implement this case?

Answer 1

Try something like this (I assume elem = "foot" in this case):

- var tag = "t" + elem;
table
  thead
  tbody
  #{tag}

should render:

<table>
  <thead></thead>
  <tbody></tbody>
  <tfoot></tfoot>
</table>

But keep in mind this table is not html conform. It's just for demonstration.
