Jquery Drop Down Hover Menu

I'm new to jQuery, I was hoping you guys could help me. I'm trying to make a hover dropdown menu, but it's extremely buggy. Can you help me clean up my Javascript? Look at my co

Solution 1:

You can do something like this:

$(document).ready(function() {
    $(".hoverli").hover(
        function() {
            $('ul.file_menu').stop(true, true).slideDown('medium');
        },
        function() {
            $('ul.file_menu').stop(true, true).slideUp('medium');
        }
    });
});

And here an example with sub-menus:

$(document).ready(function() {
    $(".hoverli").hover(
        function() {
            $('ul.file_menu').slideDown('medium');
        },
        function() {
            $('ul.file_menu').slideUp('medium');
        }
    );

    $(".file_menu li").hover(
        function() {
            $(this).children("ul").slideDown('medium');
        },
        function() {
            $(this).children("ul").slideUp('medium');
        }
    );
});

Solution 2:

For anyone who finds this in the future Aram's answer can be shortened with .slideToggle() to handle both up and down.

Here's the modified fiddle

http://jsfiddle.net/4jxph/2009/

If you have a sub-menu set to display: none; it will trigger it also, so what you'll want to do is set it to block, then add something like this

var subMenu = $('li.hoverli > ul > li');

subMenu.hover(function () {
            $(this).find("ul").slideToggle(200);
        });

And place it right below your first slideToggle. Why don't I just show you?

$(document).ready(function () {
    $(".hoverli").hover(function () {
     $(this).find('ul').slideToggle('medium');
    });

    var subMenu = $('li.hoverli > ul > li');

    subMenu.hover(function () {
      $(this).find("ul").slideToggle(200);
    });
});

Solution 3:

Not sure if you care but you want to make sure that you run the .stop() method that way the animations dont build themselves up and run over and over. Here's an example

http://jsfiddle.net/4jxph/1335/

$(document).ready(function () {
    $(".hoverli").hover(
  function () {
     $('ul.file_menu').stop(true, true).slideDown('medium');
  }, 
  function () {
     $('ul.file_menu').stop(true,true).slideUp('medium');
  }
);

});

Solution 4:

Use the finish function in jQuery to prevent the bug where you rapidly hover your mouse over the menu and out of the menu. Finish is better than the stop function previously suggested.

$(document).ready(
    function () {
        $(".hoverli").hover(
          function () {
             $('ul.file_menu').finish().slideDown('medium');
          }, 
          function () {
             $('ul.file_menu').finish().slideUp('medium');
          }
    );
});

Solution 5:

Aram Mkrtchyan's answer was almost there for me. Problem with his was if you add anything below the menu then it gets all screwy. Here is an example of what I mean, I added a div below his menu: http://jsfiddle.net/4jxph/3418/

I am submitting this updated answer using div instead of lists and list items (which I find much easier to work with, and way more flexible) and jQuery version 1.9.1

here is link to jFiddle: http://jsfiddle.net/4jxph/3423/

Here is the code:

--------------- HTML:

<divid="divMenuWrapper1"class="divMenuWrapper1"><divid="hoverli"><divclass="lbtn">
            Actions
        </div><divid="actions_menu"class="file_menu"><div><ahref="#file">File</a></div><div><ahref="#edit">Edit</a></div><div><ahref="#view">View</a></div><hr /><div><ahref="#insert">Insert</a></div><div><ahref="#modify">Modify</a></div><div><ahref="#control">Control</a></div><div><ahref="#debug">Debug</a></div><div><ahref="#window">Window</a></div><div><ahref="#help">Help</a></div></div></div></div><div>
    testing content below menu testing content below menu testing content below menu testing content below menu testing content below menu testing content below menu testing content below menu testing content below menu testing content below menu testing content below menu testing content below menu testing content below menu testing content below menu testing content below menu 
</div>

--------------- Css:

.lbtn
{
    display:inline-block;
    cursor:pointer;
    height:20px;
    background-color:silver;
    background-repeat:repeat-x;      
    border:1px solid black; /* dark navy blue */text-decoration:none;
    font-size:11pt;
    text-align:center;
    line-height:20px;
    padding:0px10px0px10px;
}

.divMenuWrapper1
{
    height: 25px;
    width: 75px;
}

.file_menu 
{
    display:none;
    width:250px;
    border: 1px solid #1c1c1c;
    background-color: white;
    position:relative;
    z-index:100000;
}

.file_menudiv 
{
    background-color: white;
    font-size:10pt;
}

.file_menudiva 
{
    color:gray; 
    text-decoration:none; 
    padding:3px; 
    padding-left:15px;
    display:block;
}

.file_menudiva:hover 
{
    padding:3px;
    padding-left:15px;
    text-decoration:underline;
    color: black;
}

--------------- jQuery (to be placed in document.ready or pageLoad()):

$("#hoverli").hover(
    function () {
        $('#actions_menu').finish().slideDown('fast');
    },
    function () {
        $('#actions_menu').finish().slideUp('fast');
    }
);
