    I think you're trying to use a browser's `alert()` function in a server-side node.js application. – Aioros Jan 17 '19 at 19:14

  • Could you show your code ? In general, for debugging questions, the relevant code is expected, this often clarifies the problem a lot, and allows for quicker and more precise answers.

node.js is backend (server side) javascript and alert is supported in UI javascript. you can use console.log(data) in node.js to check result in node.js.

  1. User press Delete

  2. Show popup with Ok/Cancel

    <div>
    Do you want to delete?
    <div id="ok-button">OK</div>
    <div>Cancel</div>
 </div>

<script> $("#ok-button").on("click",function(){ $.ajax({ url: my_url, type: "POST", dataType: "json", data: {id : "id_to_delete"}, contentType: "application/json" }).done(function(notification_from_server) {alert(notification_from_server);}); }); </script>

  1. If user press Ok, do ajax call to server that do DB things
  2. Ajax call have call back for showing "Item has been deleted" notification when it is done.
