ruby - Rails: Split and wrap each character in a string? -

I have something like this:

  & lt;% = @ votes% & gt; ;  

Outputs just like a string:

  123  

Is it easy to wrap each letter Some HTML with the helpful way?

  & lt; Span class = "outerclass" & gt; & Lt; Span class = "innerclass" & gt; 1 & lt; / Span & gt; & Lt; / Span & gt; & Lt; Span class = "outerclass" & gt; & Lt; Span class = "innerclass" & gt; 2 & lt; / Span & gt; & Lt; / Span & gt; & Lt; Span class = "outerclass" & gt; & Lt; Span class = "innerclass" & gt; 3 & lt; / Span & gt; & Lt; / Span & gt;  

You can make such a helper:

  def wrap_each_char (string, and block) string.each_char.map (& block). Add End  

Then use it like this (erb):

  <% - @votes = "123" -%> ; & Lt;% - wrap_each_char (@votes). C | -% & gt; & Lt; Span class = "external" & gt; & Lt; Span class = "inner" & gt; & Lt;% = c% & gt; & Lt; / Span & gt; & Lt; / Span & gt; & Lt;% - end -% & gt;  

Update: The above example shows a helpful way to pass a block level content, but it is worth noting that this particular example Can be simplified by simply using the every_church method on the string and by completely avoiding the support:

  & lt;% - @ votes.each_char do | C | -% & gt; & Lt; Span class = "external" & gt; & Lt; Span class = "inner" & gt; & Lt;% = c% & gt; & Lt; / Span & gt; & Lt; / Span & gt; & Lt;% - end -% & gt;
