title: Javascript percentage validation
body: <p>I am after a regular expression that validates a percentage from 0 100 and allows two decimal places. </p>
  
  <p>Does anyone know how to do this or know of good web site that has example of common regular expressions used for client side validation in javascript?</p>
  
  <p>@Tom - Thanks for the questions. Ideally there would be no leading 0's or other trailing characters.</p>
  
  <p>Thanks to all those who have replied so far. I have found the comments really interesting.</p>
