title: Add special character at end of input fields string, jquery automatically adding comma
body: <p>I am adding % symbol at the end of the string on keyup event, first I get the current value of input field and then split('%') and then I use following code</p>
  
  <pre><code>$('.percent input[type=text]').val(str+'%');
  </code></pre>
  
  <p>But this also adding comma after newly added character.

  <p>Also Would love to do it by using css but the condition is only that there should not be any image used for it neither positioning used.(Can I use :after or :befor)</p>
