title: Show div if {{}} expression returns nothing with ng-show. Angular
body: <p>I have an Angular expression which returns some data</p>
  
  <pre><code>    &lt;span class="detail"&gt;
          {{details.info}}
      &lt;/span&gt;
  </code></pre>
  
  <p>But if the expression doesn't return any data, because there may be none to return in some cases, I want another div to appear. Obviously my approach is incorrect, could someone point me in the right direction?</p>
  
  <pre><code>    &lt;span ng-show="!details.info"&gt;
          &lt;p class="no"&gt;No Data&lt;/p&gt;
      &lt;/span&gt;
  </code></pre>
