title: How to get a different link dynamically for each option tag value?
body: <p>I am creating a form through which customers can purchase an online service.<br>
  The form contains a dropdown list with a 'select' &amp; 'option' tag.<br>
  The dropdown list is created to choose a billing cycle (6 months, 1 year, 2 years, 3 years)<br>
  I want to send the user to different addresses depending on the selection of a billing cycle. </p>
  
  <p>For example:</p>
  
  <ul>
  <li>If 6 months is selected and "Order now" is clicked, the customer will be send to link 1.  </li>
  <li>If 1 year is selected and "Order now" is clicked, the customer will be send to link 2.  </li>
  <li>If 2 years is selected and "Order now" is clicked, the customer will be sent to link 3.</li>
  </ul>
  
  <p>I want to change the value of the href attribute dynamically for the ORDER NOW button for each billing cycle.<br>
  How to do the same?</p>
