Underscore.js Templates Within JSP

Question

Underscore.js templates use <%= %> for variable interpolation. Unfortunately that is also interpreted in a JSP (or GSP). Is there a way to use Underscore.js templates wit

Answer 1

@coderman's example was helpful, but, unfortunately, it doesn't work if you want to use newlines in your templates. For example:

   <@ 
      var numPages = 10;
      if ( numPages > 1 ) {
   @>
   
<@=numPages@>
   <@}@>

The problem is that the regex for evaluate won't match across newlines as described here: JavaScript regex multiline flag doesn't work

So, the solution that worked for me is:

_.templateSettings = {
    interpolate: /\<\@\=(.+?)\@\>/gim,
    evaluate: /\<\@([\s\S]+?)\@\>/gim,
    escape: /\<\@\-(.+?)\@\>/gim
};

NOTE: [\s\S] in the evaluate regexp. That's the key.
