title: Using Jquery validate plugin for negative value checking on change of the input box
body: <p>I have multiple input boxes and I have to check whether the entered values are positive or negative using <a href="http://jqueryvalidation.org/validate" rel="nofollow noreferrer">jquery Validator plugin</a>.</p>
  
  <p>It is basically doing some calculation based on the value entered in the first input box. </p>
  
  <p>The value entered must be positive, if not I should throw an error message saying the value must be positive or greater than zero. </p>
