title: Mobile numeric keyboard [0-9] in textarea
body: <p>Is it possible to open up the mobile numeric keyboard in a textarea box?</p>
  
  <p>The typical <code>pattern="[0-9]*"</code> does not seem to work with a textarea and I can't find any other information on this anywhere else. I am trying to get this working in an angular app, so is there some way to preventDefault() on the default keyboard and somehow trigger the numeric keyboard?</p>
  
  <p>e.g.</p>
  
  <pre><code>&lt;textarea id="searchBox" pattern="[0-9]*" ng-model="searchParams.searchString" rows="3" ng-blur="formatSearch()"&gt;&lt;/textarea&gt;
  </code></pre>
