sursatraj,
Try this :
<script>
function fun(textAreaName,total)
{
   var i
   for(i=1;i<=total;i++)
  {
     document.getElementById(textAreaName+i).value = "";
   }
}
</script>

<input type="button" value="Clear All TextArea" onClick="javascript:fun('txtIssue','4')">

My previous solutions is clear all textarea. Here, clear textarea based on selected row.
If you want to clear 1 textarea accordingly the related button(row), try this :
<script>
function fun(textAreaName,id)
{
    document.getElementById(textAreaName+id).value = "";
}
</script>

<input type="button" value="Clear" onClick="javascript:fun('txtIssue','1')"> <-----first row
