How to refresh the page after jquery delete

After using jQuery to delete an element or a list item, sometimes we need to reload the page or refresh the page after deletion to display the updated data. This article will explain how to use jQuery to refresh the page after deletion and how to prevent the page from refreshing after deletion.

1. Refresh the page after deletion

When we delete an element or list item, we hope that the data displayed on the page can be updated in time. After using jQuery's .remove() method to delete an element or list item, we can use the location.reload() method to refresh the entire page.

The following is a sample code snippet:

$(document).on('click', '.delete-item', function() {
  $(this).closest('li').remove();
  location.reload();
});

In this code snippet, when the user clicks a button .delete-item, it will find the nearest li element and delete it. Then, the location.reload() method reloads the entire page. In this way, the data displayed on the page will be updated in time.

2. Do not refresh the page after deletion

However, sometimes we do not want to refresh the entire page after deleting an element. In this case, we can use jQuery's $.ajax() method to update the data on the page through an AJAX request without refreshing the entire page.

The following is a sample code snippet:

$(document).on('click', '.delete-item', function() {
  var id = $(this).data('id');
  $.ajax({
    url: '/delete-item',
    type: 'POST',
    data: { id: id },
    success: function(response) {
      $('#' + id).remove();
    }
  });
});

In this code snippet, when the user clicks a button .delete-item, it will get the element to be deleted ID and sends it to the /delete-item route on the server. The route on the server will remove the element and return a response. After a successful response, the client code finds the ID of the deleted element on the page and deletes it.

The above code snippet shows a way to delete elements without refreshing the entire page. This method is faster and more efficient than reloading the entire page, so it is very popular in large applications.

Summary

After using jQuery to delete an element or list item, we can use the location.reload() method to refresh the entire page, or use AJAX to request an update on the page data without refreshing the entire page. Which method you choose depends on the size and needs of your application. Either way, we need to make sure that the removed element has been completely cleared from the page so that developers can customize page updates to their needs.
