<script> function confirmDelete(delUrl) { if (confirm("Are you sure you want to delete")) { document.location = delUrl; } } </script> <a href="javascript:confirmDelete('delete.page?id=1')">Delete</a>Another way
<a href="delete.page?id=1" onclick="return confirm('Are you sure you want to delete?')">Delete</a>
