title: Masked input field is being cleared if it is not completely entered
body: <pre><code>&lt;input id="format_ThisFormat" name="format_ThisFormat" type="hidden" value="##-##-##-##" /&gt;
  </code></pre>
  
  <p>So, I know this much to go on, but basically, my issue is that the input field is being cleared if the complete mask isn't being entered (For example, if just "12-44" is being input, the field will clear, but if "12-34-56-78" is entered, the field will stay.  I want the ability to allow for partial inputs.  Any ideas how I can edit this line to accomplish what I am trying to achieve? I'm assuming it's an issue with this line, I'm not just going to post thousands and thousands of lines of code because it won't make any sense, custom API in visual basic SPA.  </p>
