jQuery Hover Drop-Down-Menu Full Width Size

问题:

I have a vertical menu in my Website. Now i need a dropdown system in some links.
I've see this example on the internet: http://jsfiddle.net/4jxph/3018/ But i want a full width submenu. The Dropdown System of Sony is what I want. Dropdown system by Sony: Sony I've always craetet a full width size dropdown menu.
My Code: http://www.jsfiddle.net/3aK9k/4.
So what i want, when i hover the content so the submenu and again to the menu link which slidedown the submenu than the submenu should be there without some moves.

I hope I've explain what i want to do. I think it is possible but that overwhelmed my knowledge of JS and jQuery.

Can anyone tell me how to that?

You can achieve that with only CSS. Cleaner, simpler.

Live demo here : http://jsfiddle.net/4jxph/3031/

Here's the modified CSS :

body {
font-family:Arial, Helvetica, sans-serif;
font-size:12px;
background-color: #333333;
}

#container {
    margin: auto;
}

#header {
    background-image: url(images/header.png);
    background-repeat: no-repeat;
    height: 42px;
    width: 490px;
    margin-bottom: 20px;
}

#button {
    height: 32px;
    width: 184px;
    margin: auto;
}
#button:hover .file_menu {
    max-height: 100000px; 
    opacity: 1;
}
ul, li {
    margin:0; 
    padding:0; 
    list-style:none;
}

.menu_class {
    border:1px solid #1c1c1c;
}

.file_menu {
    max-height: 0;
    overflow: hidden;
    opacity: 0;
    width:100%;
    border: 1px solid #1c1c1c;
    transition: all .2s;
}

.file_menu li {
    background-color: #302f2f;
}

.file_menu li a {
    color:#FFFFFF; 
    text-decoration:none; 
    padding:10px; 
    display:block;
}

.file_menu li a:hover {
    padding:10px;
    font-weight:bold;
    color: #F00880;
}

Because you want it, here's the JS solution (cleaner than other answer):

var link = $("li[class^=nav_menu_link_drop]");

$(link).hover(

    function(){ 
        var content = $(this).next('div[id^="content"]');
        $(content).stop(true).slideDown(350);
    },
    function(){
         var content = $(this).next('div[id^="content"]');
         $(content).delay(350).slideUp(350);


    }
);

Is that doing the job ? http://jsfiddle.net/3aK9k/27/

回答5:

If I got you right you don't want the animation, for that simply set the animation time to 0. You dont need .stop() and you should consider using .hover() instead of mouseenter and mouseleave. Here is a link: http://api.jquery.com/hover/

Example:

$(link1).hover(
    function(){ 
        $(content1).slideDown(0);
    },
    function(){
        $(content1).slideUp(0);
    }
);

Here is your fiddle with updated code: http://jsfiddle.net/3aK9k/2/

EDIT: I just noticed but you have invalid html your div-tag is inside the ul-tag put it in your li... seriosly CHECK your markup... thats not the only wrong thing i noticed...

EDIT: Uhm... OK... maybe you should rethink your approuch, only because it works you shouldn't use invalid html
