Use a javascript confirm box to ask the user if they want to delete

Use a javascript confirm box to ask the user if they want to delete
<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>

Just a smart demo :)
