jQuery navigation bar mouse hover glitch

I've created a sidebar using jQuery, but I'm facing an issue. When I hover my mouse quickly on the sidebar and then move to the "red" area, the 3rd item should open a submenu, but it doesn't. How can I fix this?

Here's my jsfiddle with CSS, but it doesn't seem to work properly over there!

I am using my own CSS and jQuery version 1.11.0.

jQuery(window).load(function() {
  $('ul.insidenav > li').hover(function(e) {
    if ($(this).find('ul.insidenavsubmenu').length > 0) {
      $(this).find('ul.insidenavsubmenu').stop(true).slideDown('1000');
      $(this).addClass('arrow-down');
    }
  }, function() {
    if ($(this).find('ul.insidenavsubmenu').length > 0) {
      $(this).find('ul.insidenavsubmenu').stop(true).slideUp();
      $(this).removeClass('arrow-down');
    }
  });
});

jQuery(window).load(function() {
  $('ul.insidenavsubmenu > li').hover(function(e) {
    if ($(this).find('ul.dubinsidenavsubmenu').length > 0) {
      $(this).find('ul.dubinsidenavsubmenu').stop(true).slideDown('1000');
      $(this).addClass('arrow-down');
    }
  }, function() {
    if ($(this).find('ul.dubinsidenavsubmenu').length > 0) {
      $(this).find('ul.dubinsidenavsubmenu').stop(true).slideUp();
      $(this).removeClass('arrow-down');
    }
  });
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>

<body>
  <div class="sidebar">
    <ul class="insidenav">
      <li class="purple">
        <a href="" class="link purple"><span>ابر پژوهیار</span></a>
        <ul style="display: none;" class="insidenavsubmenu">

        </ul>
      </li>
    </ul>
  </div>
</body>

Answer №1

Your code is functioning correctly, but to ensure all elements are loaded before attaching event handlers, remember to load your custom script at the end of the body. To confirm this, adjust the JSFiddle javascript settings to "No wrap - in body"

UPDATE: It seems like specifying selector $('ul.insidenav > li') is not effective. Instead, using the more general $('ul.insidenav li') should work without any issues.

Looking at the W3Schools documentation on CSS selectors reveals a note about the ul.insidenav > li selector:

Note: Elements that are not directly children of the specified parent will not be selected.

This could be the reason for the issue, as the broader ul.insidenav li works smoothly. For a comprehensive guide on CSS selectors, refer to the complete documentation available here

Answer №2

To ensure that all of the document is loaded, it might be a good idea to wrap all the code in $(document).ready. Vladimir also suggests following this approach.

If you want more information, check out this link:

Additionally, consolidate all ready functions into one ready function ($(document).ready or $(function () {...})) and ensure that all event click bindings are within this function.
