Return table TR ID

Return table TR ID

Hi,

My table is:

  1. <table id="yourtable">
  2.         <tr>
  3.             <th width="14%">Date/Time</th>
  4.             <th width="16%">Show</th>
  5.             <th width="25%">Comment</th>
  6.             <th width="15%">Response</th>
  7.         </tr>
  8.         <tr id="1202154">
How can I reference the ID of the tr when a  button is clicked, in this case button clicked id = 1202154


Thanks
