title: Add a percentage (%) symbol to input value, but not pass with form
body: <p>I currently have nouislider working fine. However I would like to add a postfix "%" symbol to my input fields, to show the user that the value is a percentage value, and the problem I'm having is that the value being passed with the form includes the % symbol. Does anyone know a workaround so that only the value is passed with the form?</p>
  
  <p>An alternative method that I tried, to the format:wNumb method suggested in the nouislider documentation is as follows:</p>
  
  <pre><code>slider.noUiSlider.on('update', function( values, handle ) {
      moistureValues[handle].value = values[handle] + '%';
  });
  </code></pre>
  
  <p>However this is still appending the percentage symbol to the url. Is there any other way that would solve this problem? Thanks</p>
