title: jQuery get value from input type=number containing dash / minus
body: <p>I have an <code>&lt;input type="number"&gt;</code> as I want the numeric keyboard on mobile device.</p>
  
  <p>I need to get this value in javascript/jquery, which is normally just <code>$element.val()</code>. </p>
  
  <p>This works as long as the field contains a number <code>[0-9]</code>*, but if it contains a dash "-" I don't get any value at all.</p>
  
  <p>How can I get the value?, or can I use <code>&lt;input type="text"&gt;</code>; but still force the mobile device to use a numeric keyboard?</p>
