Does your click event get called?

I think so, Popup modal opens, but then I press delete button with delete url it’s just refresh page.

According to your code it changes the delete link to go to darb.php with a "delete" param of the id. If your site redirects to that url when you click the delete link then it is doing what it is coded to do.

Show us your code in darb.php as well, you are calling the page but it seems that nothing happens (no deletion) in your php page, code seems to be wrong tehre as this is where the deletion will occur.

I add darb.php code

Great. add code - var_dump($bulk_options); after this line - $bulk_options = $_POST['bulk_options']; and let me know what was returned. For your delete to work, it should be 'Ištrinti'

That is a basic problem with jQuery and other JavaScript event handlers on the page. When you press a button, a JavaScript event is triggered that you attach to it, but that does not prevent the browser to perform the default action associated with the element.

For a button or input[type='submit'], the browser will post the content to the server and reload the page. In normal cases, a page is refreshed unless there is an action attribute applied to the form (if the element is within a form).

An easy way to handle this is to add a event.preventDefault() to the handler, which prevents the browser from "refreshing" the page. So your JavaScript code should be like:

JavaScript

$(document).ready(function(){
  $(".delete_link").on('click', function(){
      event.preventDefault(); // <-- this here

      var id = $(this).attr("rel");
      var delete_url = "darb.php?delete="+ id;
      $(".modal_delete_link").attr("href", delete_url);
      $("#myModal").modal('show');
  });
});

Now your code would run and show the modal—your modal will take it from here as the browser will not reload the page.
