If js is in separate file (.js), then it's not parsed by PHP and therefore PHP tags won't work there.

In this case You could solve this by 2 scenarios:

1) Move function declaration to file that is parsed by PHP (like second block of Your code, where this function is called)

2) Add input parameter to "confirmno" function. Parameter sets "nid" value and it is given by PHP file (instead of 'onclick="confirmno()' You would use 'onclick="confirmno()'.

Code:

<script type="text/javascript">
    function confirmno(nid) {
    var con=confirm('You want keep this?');
    if (con == true) {
      window.location="notification.php";
    } else {
      window.location="confirmed1.php?nid=" + nid;
    }
}
</script>

<a href = "javascript:void(0)" style="background: #EAEAEA; padding: 5px 7px; color: #000; float: right;" onclick="confirmno(<?php echo $nid; ?>)">X</a>
