JS dropdown menu doesn't work

Question

I have some js code, that has to open my menu on hover. But it doesn't react on mouseover/out. Where am i mistaken?

jQuery(document).ready(function() {
        jQuery('#user-menu').bind('mouseover', openSubMenu);
        jQuery('#user-menu').bind('mouseout', closeSubMenu);

        function openSubMenu() {
            jQuery(this).find('.dropdown-menu').css('display', 'block');    
        };

        function closeSubMenu() {
            jQuery(this).find('.dropdown-menu').css('display', 'none'); 
        };

    });

And some html code here

<div id="user-menu" class="pull-right btn-group"><a class="btn btn-success dropdown-toggle" data-toggle="dropdown" href="#">User menu
  <span class="caret"></span>
    </a>
    <ul class="dropdown-menu" id="user_dropdown_menu"><li class="menu-2 first"><a href="/courses/user">My account</a></li>
<li class="menu-15 last"><a href="/courses/user/logout">Log out</a></li>
</ul>
  </div>

Answer 1

I would suggest using jQuery's hover instead:

$(document).ready(function() {
    $('#user-menu').hover(function () {
        $(this).find('.dropdown-menu').toggle();
    });
});

Notes:

• passing one function to hover will fire it for both mouseover and mouseout
• toggle will show or hide depending on the element's current state

try this:

jQuery(document).ready(function() {
  function openSubMenu() {
         jQuery(this).find('.dropdown-menu').css('display', 'block');
  };
  function closeSubMenu() {
         jQuery(this).find('.dropdown-menu').css('display', 'none');
  };

  jQuery('#user-menu').bind('mouseover', openSubMenu);
  jQuery('#user-menu').bind('mouseout', closeSubMenu);
});
