title: External template in Underscore
body: <p>I use <a href="http://documentcloud.github.com/underscore/#template" rel="noreferrer">Underscore template</a>. It is possible to attach a <strong>external file as template</strong>?</p>
  
  <p>In Backbone View I have:</p>
  
  <pre><code> textTemplate: _.template( $('#practice-text-template').html() ),
  
   initialize: function(){                                            
    this.words = new WordList;            
    this.index = 0;
    this.render();
   },
  </code></pre>
  
  <p>In my html is:</p>
  
  <pre><code>&lt;script id="practice-text-template" type="text/template"&gt;
     &lt;h3&gt;something code&lt;/h3&gt;
  &lt;/script&gt;
  </code></pre>
  
  <p>It works well. But <strong>I need external template</strong>.
  I try:</p>
  
  <pre><code>&lt;script id="practice-text-template" type="text/template" src="templates/tmp.js"&gt;
  </code></pre>
  
  <p>or</p>
  
  <pre><code>textTemplate: _.template( $('#practice-text-template').load('templates/tmp.js') ),
  </code></pre>
  
  <p>or </p>
  
  <pre><code>$('#practice-text-template').load('templates/tmp.js', function(data){ this.textTemplate = _.template( data ) })
  </code></pre>
  
  <p>but it did not work.</p>
