On page 10 are div with the item class.
When you click on this div, a .remove() jquery occurs and the element is deleted via AJAX.
Now after applying remove I need to calculate how much div.item data is on the page, through the code inspector I counted 9, but the script counts 1 more, first 10 (but there are 9), then 9 (but 8).

 $('.item').click(function () { var divNumberOnPage = $('.item').length; console.log(divNumberOnPage); var setCurrentPagination = $('.number').html(divNumberOnPage); return setCurrentPagination; });

    And where in the code When you click on this div, the .remove () jquery occurs and the element is deleted via AJAX. ? I can assume that the number is displayed before deletion, so it seems that there was an error - Grundy

and the element is removed via AJAX

What is it like?

No elements are deleted via AJAX - requests occur through ajax. Perhaps the error is that you delete an element in the callback of the AJAX ( complete: function(r){..} or success: function(r){..} or .done(function(r){..}) ) : after making a request. And consider the amount outside the callback, for example after calling jQuery.ajax .

In this case, an error in understanding, since the ajax-answer comes later (and the callback is executed), than the next line is jQuery.ajax after jQuery.ajax .

And the counting algorithm is correct.

    Because it is necessary to consider in the same processor as delete. Otherwise, you send a request, recount the elements - there are still 10 of them, then you process the answer and delete one.
