jQuery下拉菜单无法正常工作

Question

I tryd to made a Jquery dropdown menu when i slide the menu item it slides perfecly down and when i leave the menu item it slides perfecly up.

The only problem is when i move my mouse down into the submenu it slides up and what i want is that is stays open untill i leave the menu item or the submenu.

HTML

<ul>
    <a href="dashboard.php"><li class="dashboard icon-home">Dashboard</li></a>
    <a href="#"><li class="icon-pages">Paginas</li></a>
    <a class="trigger" href="#"><li class="afbeeldingen icon-image">Afbeeldingen</li></a>
    <div class="adminsubmenu">
        <a href="#">Submenu item</a>
        <a href="#">Submenu item</a>
        <a href="#">Submenu item</a>
    </div>
    <a href="#"><li class="icon-users">Gebruikers</li></a>
    <a href="#"><li class="icon-settings">Instellingen</li></a>
</ul>

CSS

div#adminmenu ul li {
    font-size:13px;
    font-weight:600;
    padding:7px 0 7px 28px;
    background-color:#fff;
    width:175px;
    border-bottom:1px solid #c2c2c2;
    border-right:1px solid #c2c2c2;
}

div.adminsubmenu {
    height:100px;
    width:175px;
    background:url(../images/adminmenu_bg.png) repeat-y top right #e6e6e6;
}

Jquery

$(document).ready(function(){

            $(".adminsubmenu").hide();

            $("a.trigger").mouseover(function(){
                $(".adminsubmenu").slideDown();
            }).mouseleave(function(){
                $(".adminsubmenu").slideUp();
            });

        });

And here is the Fiddle

Answer 1

You ought to put the <a> inside of the <li> , not the other way around, in order to make the HTML valid.

That said, just change your JavaScript to do exactly what you want:

$("a.trigger").mouseover(function(){
            $(".adminsubmenu").slideDown();
        });
$('.adminsubmenu').mouseleave(function(){
            $(".adminsubmenu").slideUp();
        });

Better yet, place the submenu inside the trigger element. That way, you'll still be hovering over the trigger as long as your mouse is over the submenu:

<li class="afbeeldingen icon-image trigger">
    <a class="" href="#">Afbeeldingen</a>
    <ul class="adminsubmenu">
        <li><a href="#">Submenu item</a></li>
        <li><a href="#">Submenu item</a></li>
        <li><a href="#">Submenu item</a></li>
    </ul>
</li>

new JS:

$(".trigger").mouseover(function () {
    $(".adminsubmenu").stop().slideDown();
}).mouseleave(function () {
    $(".adminsubmenu").stop().slideUp();
});

Answer 2

<li><a ... </a></li>

INSTEAD OF

<a><li> </li></a>

It's actually the other way round

Answer 3

It was doing exactly what you said. When the mouse leaves a.trigger the menu slides up. So you just have to change it to $(".adminsubmenu").mouseleave Here is what you want:

http://jsfiddle.net/2Ajuz/1/

$(document).ready(function(){

    $(".adminsubmenu").hide();

    $("a.trigger").mouseover(function(){
        $(".adminsubmenu").slideDown();
    })
    $(".adminsubmenu").mouseleave(function(){
        $(".adminsubmenu").slideUp();
    });

});
